Quality and safety
This BTC-DYC820VX battery (4000 mAh 21.6 V, Black) contains advanced technical components and has been tested according to strict CE safety standards.

Next to this, the BTC-DYC820VX battery is made from high quality cells that do not suffer from a so-called 'memory effect'.
Factory Fast
The BTC-DYC820VX battery is factory fast. Batteries lose performance over their lifetime, even when they are not used.

So you can be sure that you will get a brand new high quality battery!
