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.

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.

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.

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.
