Hi, I am making an adjustment to my house alarm so the 2 external siren boxes are powered by one lead acid battery (using in total about 25m of cable). Previously the siren boxes each ran on 6 D cells. I have a 6v 4ah lead acid battery, and a 3 stage (with float) 750ma charger which will be connected permanently to the battery.
Regarding series string vs parallel/etc... for battery balancing. Technically all batteries are a series string of cells (if more than 2 volts working voltage for lead acid). If you have a "bad or weak" cell--Trying to get it fixed without damaging the rest of the cells in series is the problem.
