Gardtec 595 problem

[polomints]

My system suddenly sounded internally today.
The keypad display reads fuse/battery fault.
The 7ah battery was replaced in December 2019
I checked the in line battery fuse and the other two on the pcb all are ok.
The voltage of the disconnected battery is slightly low at 11 volts.
And measuring the voltage at the panel battery terminals with the battery disconnected is 6.5 volts, this seems low to me.
Can anyone offer advice please.

Who replaced the battery ....? If it’s only putting out 6.5v then it’s faulty ....by the way if your struggling to find a pcb pm me

Thanks for your responce.
I replaced the battery it had been in the panel since 2016
The 6.5v is from the panel
I was wondering if the pcb charge circuit may be faulty, I fitted the panel some years ago and I wondered if replacements where still available, or if a current gardtec could be fitted.
The system has two kp four expanders and one relay o/p module on it.

Big question ....are they 6 or 4 wire keypads ? Ace or gtag ?

The kp are wired with 6 cores
The kp are earlier type than you mention they physically larger lcd original 800 series
Inside the panel cover it states the panel is 4 wire enabled
