Backup alarm battery

I've had my 12V (lead acid?) battery for many years. Does one need to cycle it for longevity like NiCd or NiMH?

The practical working life of a sealed lead acid (SLA) battery is about 5 years. Really, anything longer than that is essentially borrowed time. You don't want to discharge it. Every full discharge on a SLA shortens the battery life.

I dont think it was asked if it was sealed or not... Lead acid batts need a proper charger is all and many dont no the charging procedure for deep cycles batteries... sealed agm are different then lead acid...

Let us know...

The same principal applies to an AGM battery. It's a different chemistry, but the lifespans are basically identical.

It's an SLA and is connected in the alarm panel box. The charger is part of that panel and is doing it's job. Just wondering if there is any (preventative maintenance) PM required. I guess not, just replace it every 5 years or wait until the Low Battery message appears?

Other than making sure the push-on terminals aren't corroded.... there is no user service.
Five years is a good run. I've seen new replacement alarm batteries only last 2-3 years. The quality is not as it good as it used to be.

I think the battery in my system lasted more than ten years.

I've not kept records and my memory isn't what it used to be but 5 yrs sounds about right for battery life on my system. I let the keypad tell me when the battery needs replacing and make sure the connections are clean when I hook up the new one. I know I've not gotten anywhere near 10 yrs out of any of the batteries in my alarm system

A ten year old battery is not uncommon. I'm just pulling lead acids now from 15+ years ago BUT those were American made batteries. The batteries from Japan were noted for longer life but the batteries from China and the RoC's have miserable life.

I generally tell people that they should expect 3-5 years; and lately most of the newer import batteries have been failing within 5-6 months of the 3 year mark (even taking into account that Florida is a rough environment for batteries).
