Battery Replacement

Featured Replies

Hi

Would appreciate your help in trying to source a new battery for my burglar alarm mainboard, I am assuming this is the problem as the alarm goes off every time we have a power cut, also it's over 20 years old!!

I don't have a lot of information to give unfortunately, what I know is it's a Concept System Advanced Microprocessor Control. Also, the writing on the battery is very faded, what I can make out is that it is possibly 1.9ah. I may be able to get a little more info if needed, hopefully that will be enough.

Thanks 

Jeff

*Usually* would be a 2.8ah

 

But either the above or a 2.1 will suffice.
