I have a DSC 1555 system. The main battery is going or is gone and I am getting a low battery error on the keypad.

The battery is a DSC BD 4-12. This is a 12 volt 4 amp sealed lead acid battery.

How close do the amps have to be?

Online there is only 1 source for the DSC BD battery that I can see on Google. In addition, most batteries I am finding online are basically 12 volt 4.5 amps. 12 volts 4 amps seems like a rare battery to find online.

I tried brick and mortar and went to Radio Shack and they sell a 12 volt 5 amp sealed lead acid battery for 29.99.

Will this work? Forgive my electricity ignorance but isn't the amp hours just a reflection of the storage capacity.

Please advise.

Thanks

The battery standards have changed. 4.5 to 5 ah is now the standard. The panel will charge up to about a 10 or 12 AH battery.

Anything in between will work. Bigger battery = longer backup power.
