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!

Assurance and warranty
The BTC-NK4LSL battery (1500 mAh 3.7 V) comes with 12 months warranty. Besides this, we offer a unique 30-day money back guarantee: in case you are not satisfied with the product, for whatever the reason, you can always return it and get your money back.
Quality and safety
This BTC-NK4LSL battery (1500 mAh 3.7 V) contains advanced technical components and has been tested according to strict CE safety standards. The BTC-NK4LSL battery contains a chip that prevents overcharging and short-circuiting. Next to this, the BTC-NK4LSL battery is made from high quality cells that do not suffer from a so-called 'memory effect'.
Factory Fast
The BTC-NK4LSL 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!
