I've got a small sealed lead-acid 12V 1.3Ah battery I need to frequently keep charged (wireless tow lights), and I have some problems to solve around that.
1. The charge cord for the battery is "dumb" and just a simple lighter socket plug-in. If you follow the manufacturer's advice of "you can leave it plugged in all the time" you will kill the battery by over-charging it. Seen it happen many times, you'll leave it plugged in because you forget to unplug it.. boom, seriously shortened battery life.
2. I'd like to source an automatic charger that actually does what it claims. It seems the Battery Tender type stuff still just boils people's batteries to death. The charge cord plugs into a small socket on the bottom of the tow light housing. Whatever suitable charger I might find, I'd just hardwire the output to that charge cord end, and hardwire the input side of the charger to a 12V supply in my truck. There's all kinds of 120V->12V stuff that claims to do this (Battery Tender, Noco Genius, etc.) but I need a 12V->12V solution so it can live in my truck.
The batteries:
Any ideas? Thanks!
