Synergy DigitalReplacement Battery, Compatible with Bushnell AE542730P Replacement, (Li-Pol, 3.7V, 400mAh) Ultra High Capacity, Replacement for Bushnell AE542730P Battery

easy install

I've tried to replace the internal battery to my Nextbase N522GW dash camera, as such, I was hoping to "beef up" the capacity of the OEM 350mAh battery and got this battery in it's place. Ultimately the space in the dash cam is the deciding factor on which battery I would use, and since the OEM and this battery was so close in mAh, I thought for sure this battery would be the best option.After ordering, the inner Tim the Toolman Taylor in me wanted to see if I could perhaps turbocharge the capacity and also ordered a 600mAh battery, but I had little hops that the 600mAh battery would fit as common sense would tell you; larger capacity - bigger in size battery.I've enclosed two pictures of the batteries; one side by side, and the other with this battery on top of the 600mAh battery (I have the battery offset as the battery covers the larger capacity battery width and thickness wise).Now granted one could say that the 600mAh battery is actually a 400mAh, and/or the 400mAh is actually a de-rated 600mAh battery listed as a 400mAh, so on and so on.Ultimately, I don't have the ability to test capacity and ended up using this battery as the length of the larger battery prevented me from closing up the dash cam when installed.I imagine that the majority of these batteries listed here are not of the highest quality and ultimately I may have just wasted my time and hopefully will remember to come back to update the battery's capacity and life span.Ultimately it's buyer beware.I hope this helps..

Battery has only 50% capacity. Must be years old?

don't buy. Took a charge once, dead after one round of golf.

Replaced the Bushnell geo original. Back to getting 5-6 rounds before charging. Easy to replace.
