Frequently asked questions

Throwing away a battery with the regular rubbish is undesired. A battery contains substances that are harmful to the environment. There are many places all over the country you can bring your batteries to, to dispose of them. The battery will then be recycled.

BatteryUpgrade.com sells some original batteries. Most batteries are from a compatible brand.

When you purchase a battery, the manufacturer provides an indication time. However, this is a prognosis based on optimal circumstances. The actual lifespan of the battery depends on the way that the device is used. For instance, if you are using the battery in a laptop or smartphone, the software has a significant influence on the actual lifespan.

The voltage indicates the amount of charge there is on a connection. The voltage of the battery needs to be the same as that of your current battery, or at least have a difference that is less than 0.5V.

mAh is the current intensity, or amperage. The current intensity is indicated in milliAmpere per hour. A battery with a high capacity (mAh) has a longer lifespan. The size of a battery with more mAh can in some cases be bigger, because it stores more energy.

Watt is a measurement unit used to quantify the rate of energy transfer. The power of a device expressed in watts corresponds to the energy required for its operation. You can calculate the wattage by multiplying the mAh with the Voltage.

The capacity of a laptop battery is measured in milliAmpere-hour (mAh). The higher this number, the longer you can use your device before it needs charging again. The mAh does not affect the operation of the battery with your device. More capacity does mean that the battery might physically be bigger.

Batteries largely consist of cells. The separate cells are packed together in a casing. The raw materials used for the electrical charge of a battery can differ by type. The most common types are: Li-ion, Li-po, Ni-MH and Ni-CD batteries. In Li-ion batteries, the cells contain lithium, and in Ni-MH batteries they contain nickel. Every device requires its own type of battery. Ni batteries are mostly used in electrical hand-operated appliances, and Li batteries in laptops and smartphones.

A battery is a product that stores electrical energy as chemical energy, and then releases it as electrical energy again when necessary.

Never throw a used battery in the rubbish bin. Batteries contain various harmful substances, and if you just throw them out these substances will end up in the environment. You can bring your batteries to a battery recycle location.

These are the (common) types of batteries:
1: Alkaline battery: an alkaline battery is not rechargeable. Examples of alkaline batteries are the AA and AAA batteries.
2: Ni-CD battery: are mainly used in power tools such as drills. These batteries suffer from the memory effect, which means that if you don't discharge the battery completely each time, they lose capacity. Under the new EU legislation that came into effect on 01-01-2017, the sale of Ni-CD batteries has been stopped.
3: Ni-MH battery: again, a battery that is mainly used in power tools, but also rechargeable AA and AAA batteries. The Ni-MH battery has a larger capacity than an Ni-CD battery, and can be seen as a replacement for Ni-CD batteries.
4: Li-ion battery: these batteries are mostly used in notebooks, smartphones and cameras. A Li-ion battery retains its capacity better.

A dry cell battery is completely sealed and maintenance-free. Whether you hold the battery straight or upside-down, it will always supply power. A wet cell battery, on the other hand, contains a liquid (electrolyte) that will seep out of it if you don't hold it completely horizontal. It is mostly used for industrial purposes or in vehicles.

Aside from the current (Volt), the internal resistance (Ohm) is important. You can compare the internal resistance of the battery with a tap that water runs through: if the internal resistance (Ohm) is low, it lets through a lot of water (current); if it is high, little water (current) can flow through.

Between the positive and the negative poles of a battery, there is a current (voltage). Since the current between these poles runs through the device, this device must be tuned to a certain voltage, otherwise the device will not work. The common cylindrical and rectangular batteries are 1.5 Volt. Some battery types are a little different. Especially for button cell batteries (for example lithium 3 Volt), the difference in voltage can influence the functioning of the device.

When the positive and negative poles come into contact with each other, short circuit occurs. After that, the battery doesn't work any more. Short circuiting must be avoided, because gases could be released due to the high internal pressure (heat). This can lead to the battery exploding.

1. Always place the battery with its positive and negative poles on the corresponding icons in the device. 2. Never open up batteries. 3. Do not attempt to weld or solder batteries yourself. 4. Never throw batteries into a fire. 5. Never throw batteries into the water. 6. Do not keep batteries in damp/wet spaces, such as the fridge, unless they are packed air-tight.

There are two types of non-rechargeable batteries. Alkaline and Zinc batteries. Alkaline batteries last longer and are better suited for devices that require more power.

Yes, alkaline batteries last longer.

You can recognise battery sizes by their name and code. Most names are universal. Some examples are: (L)R03 AAA: small penlite batteries, (L)R6 AA: penlite batteries, (L)R20 D: large block battery ,(L)R61 E: 9V block battery

No, normally, these batteries cannot be recharged.

Lithium batteries are characterised by a low self-discharge. The voltage is high. Therefore, these batteries are usually used in in applications that require higher voltage, such as microprocessors.

You can compare a rechargeable battery to a car battery. The battery can be recharged up to about a thousand times, when used properly. A rechargeable battery can maintain a current of 1.2 Volt almost until the end of its life. After that, the battery quickly dies.

1. longer lifespan (1000 charging cycles) 2. more environmentally-friendly than regular batteries (less waste)

Yes, usually. Rechargeable batteries have a stable current.

In extreme weather conditions, rechargeable batteries work better than non-rechargeable batteries.

It is best to use a charger that is meant for Ni-MH batteries. These charge the batteries with a high charging current. The often cheaper chargers suitable for Ni-CD batteries make use of a weaker charging current. It is possible that a Ni-MH battery does not get charged fully.

The most common types are: Ni-MH, Li-ion and Ni-CD batteries.

Ni-CD advantages: cheap, can handle extreme conditions well. Average lifespan (about 500 cycles). Disadvantages: they gradually lose their maximum capacity each time they are charged without being completely empty (memory effect). The cadmium component is toxic and is no longer allowed to be applied worldwide. Starting from 2017, Ni-CD batteries are not allowed to be sold any more. Ni-MH advantages: higher capacity than Ni-CD. Are charged faster than Ni-CD. Less toxic components. Disadvantages: average lifespan is shorter (about 400 cycles). Cannot handle extreme temperatures and deep discharge well. Li-ion advantages: high energy density, compact shape, no maintenance required (no memory effect), low self-discharge. Disadvantages: more expensive to produce, cannot handle deep discharge.

The capacity determines how long you can use your drill. However, the capacity is merely an indication. It is therefore unfortunately not possible to calculate the amount of hours you can use it. This depends entirely on the way you use the device.

1. Avoid exposure to extreme temperatures. Both heat and cold are not conducive to the battery capacity in the long run. 2. Keep the battery contacts clean. If there is more resistance than is desirable, there is less capacity to work with. 3. Use an Ni-CD or Ni-MH battery regularly. Self-discharging will reduce the capacity increasingly. 4. Only use the provided charger for charging the battery, or a charger of which you are certain that it's compatible. 5. Make sure that the battery can't get wet, and never place it in the freezer, oven, or microwave.

Lithium batteries contain relatively much energy, which is stored in a small space. Because devices, such as cameras for instance, have increasingly more functions, more energy is required from the battery.

It's better for the battery if you take it out after use, and store it somewhere on room temperature. Even when the camera isn't used, electrical currents can continue to run, causing self-discharging of the battery. This reduces the lifespan of the battery.

You can do that in two ways on BatteryUpgrade.com. You can search by the brand/model of your camera, or by the unique part number that is printed on the battery sticker.

With the newer types of batteries (Ni-MH and Lithium), it doesn't matter much if you put the phone back or not. However, the older Ni-CD type batteries are susceptible to the memory effect. It is better to not place these phones back in the docking station during the day.

You can find that out in two ways on BatteryUpgrade.com. 1: On your battery, you can find the part number (unique identification number). With this part number, you can search for the right product using the search bar. 2: You can search by the brand/model of your cordless phone in the search bar or through the navigation buttons.

Button cell batteries are often used for appliances such as watches or hearing aids.

The following types of button cell batteries are available: Silver oxide - used mainly in watches and cameras. Suitable for high, constant voltage. Alkaline - mainly used in electrical appliances. Suitable for high currents. Lithium - mainly used in cameras. Suitable for low load. Zinc-air batteries - used in hearing aids. No high loads

The negative pole is on the top side. The positive pole is on the wider bottom side. The side with the positive pole usually indicates the brand and type.

Air activates the battery, so to speak. When the sticker is removed, air can flow into the battery through tiny holes, which activates the battery.

The easiest way to find this out, is to search by the information that you find on the original battery, in the search bar on our website. Every battery has a unique part number that can easily be found in our database.

A button cell battery is a round battery with a diameter that is larger than its height. It kind of looks like a button, hence the name.

Take the laptop off the adapter. Next, take out the battery by opening the sliding locks (this doesn't apply to any internal batteries). You can now take the battery out of the laptop. You can place the replacement battery with the same method.

The voltage may deviate no more than about 0.5V. A difference of more than 0.5V can cause recognition issues, or even damage your device.

The capacity of a laptop battery is measured in milliAmpere-hour (mAh). The higher this number, the longer you can work on your laptop before it needs charging again. The mAh does not affect the way the battery works with your laptop. However, more capacity does mean that the battery will physically be bigger. So a battery with a higher capacity could stick out a little bit.

If your laptop is no longer charging, but works normally, it's usually a problem with the laptop battery. Check first if the adapter is correctly connected to the laptop and plugged into the power outlet. You can usually tell by the indication light. If a charging icon doesn't appear, that probably means that the laptop adapter or the charging port on the laptop are defective. If a charging icon does appear, that probably means that the battery doesn't work any more.

All our products meet all the right quality requirements. The products are manufactured with the utmost care. All products comply with the strict ISO9001, UL and CE requirements. In addition, all products comply with the RoHS environmental directive that has been in place since July 2006.

This is probably because you purchased a battery with a higher capacity (mAh). This means that the battery will last longer than a regular battery. More capacity generally means that more cells are used in a battery, making it physically larger in size. This can do no harm, the functionality of the battery remains the same.

The compatible batteries are not made by the original manufacturer and are therefore often cheaper. You can use a compatible battery without any problems. There is no difference in important factors, such as voltage and the connector.

BraunOni has been working with the same supplier for battery products for the past 13 years. The products are tested extensively and have all the necessary quality documents. Our products are manufactured with the highest possible care. All products comply with the strict ISO9001, UL and CE requirements. In addition, all our products comply with the RoHS environmental directive that has been in place since July 2006.

You can test this by turning on the laptop without the battery, but with the adapter. If the laptop starts up properly, the issue will probably be with the battery.

Laptop batteries can have many different part numbers. To keep all the information understandable, the most commonly used part number is indicated. It is therefore possible that this number is different from yours. It is no issue however, the battery will fit and work with your system.

Manufacturers often produce batteries for multiple laptop models. Each combination receives its own battery part number. As a result, it is possible that a battery has multiple part numbers.

A Li-ion or Li-Po battery does not require a start-up procedure. So the battery doesn't need to be charged and discharged for the best result.

It is wise to charge the battery for about 50%. Next, it is best to remove the battery and store it somewhere dry and on room temperature.

A battery will always get warmer when it's being used or charged. However, if a battery becomes unpleasantly hot, this indicates a battery problem and it is advisable not to use the battery again.

The only batteries that still contain heavy metals are the Ni-CD and Lead batteries. For that reason, the Ni-CD batteries may not be sold any more from 01-01-2017. The alternatives like the Ni-MH and Lithium batteries are also not very healthy for the environment, but they are less harmful.

Individuals, stores and companies can return used batteries to municipal collection points, or to battery collection points in stores for instance.

Most batteries are recycled.

The voltage specifications must match those of your old adapter (a small margin of 0.4V is allowed). The maximum current (MilliAmpere) may deviate positively. However, an adapter that provides too little capacity to a laptop can be dangerous. It will have to 'perform' harder and will overheat because of it.

You can find that out in two ways on BatteryUpgrade.com. 1: On your adapter, you can find a part number (unique identification number). With this part number, you can search for the right product using the search bar. 2: You can search by the brand/model of your laptop in the search bar or through the navigation buttons to find the right product.

It is normal for adapters to warm up. However, too hot is not good of course. It is therefore wise to keep the adapter out of the full sun.

It is very likely that the adapter port of your laptop is broken. This part is called the DC jack. The DC jack ensures that the electricity actually goes into your laptop.

Yes, that is possible. The most important thing about a replacement adapter is that its specifications correspond to the original adapter.

Yes, you can.
