Charging Back Up Battery?

12v so is it safe to use a car battery charger ?

Certainly not, there's every chance the alarm battery will suffer permanent damage and there's a small possibillity it could explode.

Alarm panel control batteries require trickle charging over a period of upto 24 hours from a regulated 1Amp max DC charger.

As the title says, "How do I charge up the back up battery from a control panel"?

I've replaced my old Optima G3 control panel and want to use the battery for other things. 12v so is it safe to use a car battery charger?

i'd wonder how old is this battery? if over 3 years likely a better use would be a door stop.

as for using a car charger not so good an idea as they can deliver far to much current to quickly into a faulty battery (some can develope intternal shorts if the plates buckle), thats when things get a bit hot and go pop - loudly, they are designed for higher capacity lead acid/gel as used on cars. if you have a battery conditioner as used on motor bikes or caravan to keep them topped up, that will do the job or you can buy a charger from Maplin's or most good model shops (used in r/c cars boats etc.).

if you want to experiment with electronics or powered models then get a stablised power supply where you can control the current and voltage limits, again from maplins as they are very reasonably priced.
