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.
The most common rechargeable batteries are lead acid, NiCd, NiMH and Li-ion. Here is a brief summary of their characteristics. Lead Acid – This is the oldest rechargeable battery system. Lead acid is rugged, forgiving if abused and is economically priced, but it has a low specific energy and limited cycle count.
