NickM Posted April 20 Share Posted April 20 (edited) Hi All, The battery for my home alarm system is taking a bit of a hammering during this latest round of loadshedding, to the point now where it starts making warning noises toward the end to a 2.5 hour session. Not ideal at 4am. I tested its voltage and it showed 9.2v halfway through a recent outage, which I initially thought was great until I realised it was a 12v battery and not 9v. So I'm looking for a recommendation on a good replacement battery - or are they all much the same in terms of quality? I've attached a photo of my current battery and system. All it really does is supply the pannel, 4 PIRs, 2 LEDs and I'd guess some sort of transmitter that sends signal to our security provider. Any recommendations would be appreciated. Thanks Edited April 20 by NickM Typo Quote Link to comment Share on other sites More sharing options...
Tim003 Posted April 20 Share Posted April 20 Blue nova 12v 8ah lithium battery should do easily do the job. Blue nova 8ah NickM 1 Quote Link to comment Share on other sites More sharing options...
Vin Posted May 13 Share Posted May 13 Alarmtec has a battery Kit just for this purpose. https://www.alarmtec.co.za/batteries/forbatt-battery-kit-p-1882.html I have been using the setup above for more than 2 years through the worst of loadshedding with not issues. I do have a wireless setup though so the only things draining the battery are the panel, keypad, radio pad . Quote Link to comment Share on other sites More sharing options...
snoops Posted Tuesday at 08:15 Share Posted Tuesday at 08:15 (edited) I have the same problem with the same IDS system. Have to keep on replacing 1 x 12V 7Ah as result of the high number of load shedding cycles killing the batteries. Two possible solutions. 2 x Forbatt 8Ah 12Volt Lead Acid Gel connected in parallel will double your Ah value. So 12V 16Ah instead of 1 x 12V 8Ah. They just wont fit inside the IDS box. Or - and I did speak to BlueNova about this. They have a replacement Lithium battery (Blue nova 12v 8ah lithium) and they recon you dont need to modify the charger of the IDS alarm to charge their BlueNova battery, so its a drop in replacement. But its pretty pricey - about 3 times the price of one lead acid or gel 12V 7ah. The Lithium battery will be able to discharge further than any lead acid battery can. Without issues.

That would take some strain off of the SLA battery. Quote Link to comment Share on other sites More sharing options...
