Q: How do I recharge the battery?

Be VERY careful with this type of battery! If you do get it wrong you will have a chemical fire on your hands, that won't go out until the reaction has finished. Otherwise, the unit it is intended for will correctly charge it when fitted.

Q: will this battery fit a Nextbase 312G Dashcam.

Yes - it works on our dashcam. There is a Youtube video by someone who shows you how to do it. You will need a soldering iron and solder and some micro screwdrivers to do the work.

Q: Is this battery suited to a next base 522gw

Hi - not sure about it fitting a 522gw, fitted to mine which is a 512gw and works perfectly.

Q: I need a 7.4 v battery for my ebook and the exact replacement is not available in the uk. can i use 2 of these in series ? will it charge correctly ?

Hi, this is a li-ion battery I don't think it is suitable for charging in serial.
