About the product:
I love my phone and when you go to a phone outlet they tell you how difficult it is to get a new battery for your phone. Well I got one first time, and so pleased that I have my old phone back. Thanks again Happy to recommend you to others Linda(:-

Dear BatteryUpgrade, Thank you for price and service of the battery ordered. I thought the delivery was a little bit slow but to be expected, I suppose, in view of the fact that it was coming from Hong Kong - I was just a little impatient! Otherwise an excellent service, I have already recommended you to friends. Thanks! Kind regards, T. Harnisch

Unfortunately, didn't take note of when the battery arrived - only remember thinking it was a little on the late side.

Very good service. I ordered two batteries and when only one arrived I worried that they only sent me one. But after a mail I understood that they sent them both seperately. What a service!

Even though this order got stuck in customs, delaying the delivery and making me pay extra fees, the guys from www.batteryupgrade.com honored their word and have refunded me with those fees. Excellent seller, my personal recomendation for all your battery needs. No other seller has worked so hard in trying to fulfill his customers requests.
About the product:
Works flawlessly, as expected. The batteries from www.batteryupgrade.com are reliable and are not ripoffs.

General:
Good product offer. Delivery was slow (thereafter I read that this is normal because the products are shipped from the other site of the world)
About the product:
I expected longer battery time on my GSM, I don't see any difference between the new and old (3 years) battery. The other battery's where broken so it's working again. Nice.

Quality and safety
This BTC-NK4CXL battery (750 mAh 3.7 V, Black) contains advanced technical components and has been tested according to strict CE safety standards. The BTC-NK4CXL battery contains a chip that prevents overcharging and short-circuiting. Next to this, the BTC-NK4CXL battery is made from high quality cells that do not suffer from a so-called 'memory effect'.
Factory Fast
The BTC-NK4CXL battery is factory fast. Batteries lose performance over their lifetime, even when they are not used.

BatteryUpgrade.com makes sure that the ordered battery can be shipped directly after production by working together with the manufacturers. So you can be sure that you will get a brand new high quality battery!
