About the product:
Upgrade battery for my trusty Nokia 2760. I know, old stuff, but my life is on that phone. The battery finally died before Christmas. Quick search took me to your site, and I was delighted that a battery was available. As it says, an upgrade too, so I don't have to keep recharging so frequently. Well pleased and many thanks for excellent service.

About the product:
Was so relieved to find a replacement battery for my old 'cellphone'. Didn't like the prospect of having to purchase a smart device just yet.

Excellent service. I didn't need to search far for what I wanted as it was a repeat order so a quick click on the right item already logged in to my account and it was that easy. Arrived promptly and in perfect condition. Thankyou.
About the product:
I am always doubtful about buying batteries for my mobile phone. I've been stung in the past with fakes. It's so good to finally find somewhere I can trust with the genuine article. Works fine. Thankyou again.

Quality and safety
This BTC-NK4BML battery (750 mAh 3.7 V, Black) contains advanced technical components and has been tested according to strict CE safety standards. The BTC-NK4BML battery contains a chip that prevents overcharging and short-circuiting. Next to this, the BTC-NK4BML battery is made from high quality cells that do not suffer from a so-called 'memory effect'.
Factory Fast
The BTC-NK4BML battery is factory fast. Batteries lose performance over their lifetime, even when they are not used. Many importers and resellers store their batteries in stock for a long time before they are sold. 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!
