My husband loves his old mobile phone and didn't want to upgrade to a smart phone but he needed a new battery. He found out about you guys. We found the right battery easily on your website and ordering was very straight forward. We felt we could trust the site because it said it was a NZ site. We felt a bit apprehensive when the site was in pounds but felt the product wasn't too expensive so we took a chance.
About the product:
The battery arrived in reasonable time and we were deigned that it was exactly what we'd ordered and hoped it would be. It even came charged and ready to go. My husband is so happy

We didn't realise that our 'phone battery was so bad until we bought a new one from you. The price was cheap, the delivery very quick and the battery is better than the one which came with the 'phone. Thanks for your help, Mike Brooke

Quality and safety
This BTC-NK4USL battery (1000 mAh 3.7 V) contains advanced technical components and has been tested according to strict CE safety standards. The BTC-NK4USL battery contains a chip that prevents overcharging and short-circuiting. Next to this, the BTC-NK4USL battery is made from high quality cells that do not suffer from a so-called 'memory effect'.
Factory Fast
The BTC-NK4USL 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!
