How long should my batteries last?

I have OEM deep cycle 24 type batteries in my 2005 Safari. How long should I expect them to last?

Greetings from the Florida Panhandle

I have a 2005 25FB, named Lucy, that I bought new in June of 2006. The Airstream Dealer put two new Interstate batteries in when I took delivery. Lucy had sat on his lot for 16 months. Lucy has been slept in for 435 nights and has covered 50,000 miles since new.

The batteries that came in Lucy are still operating in her, and are holding a good charge. I don't think that batteries in an Airstream usually last this long. Possibly Lucy's regular use all year round has something to do with this.

I am watching these batteries like a hawk as I consider myself on borrowed time.

As you'll read in the FAQ 65CV posted a link to, battery life varies. My experience with deep cycle and golf cart batteries is that you'll notice a shortened dry camping length before the batteries die completely. For example, if you can normally dry camp on battery power for 4 days, and you start to notice that you're only able to go 3 days, it's time to replace them.

Post # 2000 for Bob.

Hi, my batteries lasted about 3 1/2 years of ownership or about 4 years since production of my trailer. "No set time limit on anything electrical."

Being in the battery sales bizz...I always tell my customers...."use it or lose it"...when asked about battery life...

As to questions about 'life' in years, it really depends initially on the 'quality' of the battery you purchase, IE: is it a full plate battery, is it 'heavy' indicating it's got lots of plates...

From then on, it really depends on how you are able to care for your batteries, keep them charged, don't let your converter/charger 'overcharge' them, don't leave your batteries unattended for long periods of time when they will self discharge, allowing sulfate to build up on the plates causing loss of capacity, use distilled water when servicing, etc, etc...

As a general 'rule', I answer, in normal use, you should get between 4 - 6 years of 'useable' service under normal care...quality batteries can and do exceed 6 years of service, but only if properly looked after, and not just installed and forgotten...
