If its totally flat it is duff. These batteries tend to need to be charged
up either all the time or for a period every couple of months to keep them
working.I had a dryfit one in a Grundig piece of gear that had not been used
for nearly a year and it would not hold a charge.
However, are you absolutely sure the charging circuit is OK. I remember the
thread and I did wonder at the time whether some other damage had occurred
to the control box.

Hi all

Following alarm issues caused by a power cut I have fitted a new
battery from Screwfix.

But it appears that it had been on the shelf a while and was low
on charge.

The battery is a 12v 7Ah lead acid jobbie.

My question is how long is it likely to take for the alarm power
supply to charge the newly installed battery?
The alarm is a Texecom Veritas Excel model.

Thanks

Phil
