## Customer Reviews

### ⭐⭐⭐⭐⭐ Fits perfectly and came fully charged
*by M***B on 7 January 2022*

I wasn’t sure if buying a battery for my Nextbase Dash Cam was worth the risk but I can confirm that, despite being a fiddly fit, it is now back to it’s new state. Care needs to be taken when dismantling the unit, the 4 screws holding the case together are tiny and easily lost (a small magnet helps to keep them safe) and a further 4 tiny screws holding the motherboard in place are also fiddly. Once the board has been lifted free the battery needs to be carefully levered out of the base, it is held in place by double sided foam tape, and needs a little persuasion to release. My battery came with a tiny plug which I removed and I cut out the old battery which was distinctly pot bellied! Leaving a couple of inches attached to the board, soldering directly to the board is very fiddly so I opted to join the new leads to the tails of the old one using heat shrink tubing to cover the joints, in retrospect I could have made the new battery leads a little shorter, space in the case is limited and folding the leads around to fit it back together proved a little more difficult than I thought, shorter leads would have made it simpler. The overall result was a perfectly working Dash Cam back to original condition. Just a finishing note, you will need a very small watchmakers crosspoint screwdriver to remove the tiny screws.

### ⭐⭐⭐⭐⭐ Will fit a Nextbase 312GW
*by C***W on 13 July 2022*

Took a chance and ordered the battery for my Nextbase 312GW dashcam. Small Philips screwdriver required for the x4 outside screws & x4 which hold down the circuit board, 8 screws in all plus a very small tip soldering iron. Removed the old battery by using a razor to cut the adhesive tape because it is well stuck down, in that way you won't damage anything.Whilst fitting the new battery I didn't bother to stick it down like the original because this one is slightly longer and thicker and I wanted the battery to find its own place within the tight space, being slightly thicker it wasn't going to move. JOB DONE! Works a treat plus the higher mAh rating should allow it to hold a longer charge.

### ⭐⭐⭐⭐ Nextbase 312GW battery
*by B***2 on 31 October 2021*

Fits the nextbase 312gw and works but you do have to remove the plug and solder the wires onto the pcb.
