If I were to implement a simple battery backup system like this to power several WiFi radios in a field situation, how would the battery handle it? Would trickle charging it like that wear it out after several months? Or years?
For example, the system could have power for perhaps three or four months, and then need battery backup for half an hour if the mains power went out.
I have seen some battery systems that monitor the battery's charge, and when they do charge it, they use a pulse system.
Do I need something like that? Or will this simplistic approach be effective?
BTW, this is a standard 12v Lead-Acid battery like from a UPS.
