Quality and safety
This BTC-NK4SML battery (860 mAh 3.7 V) contains advanced technical components and has been tested according to strict CE safety standards. The BTC-NK4SML battery contains a chip that prevents overcharging and short-circuiting. Next to this, the BTC-NK4SML battery is made from high quality cells that do not suffer from a so-called 'memory effect'.
Factory Fast
The BTC-NK4SML 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.co.uk 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!
