New battery question
#1
Posted 13 October 2020 - 12:43 PM
Made the mistake of not doing anything with our battery during the 16mo we haven’t used the camper. Just set off on a week trip and it’s dead and won’t charge.
Can I buy a regular deep cycle car battery? Or is there a special kind i need to buy. Can one buy these at a Napa/Autozone/etc?
Sorry if these are dumb questions, just never dealt with the battery issue before.
Thanks

The short answer why the old battery will not hold a charge..most likely sulfide crystallization on the plates.
A deep discharge battery (I wouldn't recommend a crank or dual purpose marine battery) of the same group size should work fine. I would stick to the same group size to ensure it fits into the space. If you have the option on your controller, be sure to select/enable the correct battery type.

So since it’s only 2 years old I’m curious if it can be charged or if I’m better off buying a new one (and can I get that at an autozon).

How are you trying to charge the battery? If you have the SurePower isolator, the voltage drop to the dead battery may be too much to enable charging from your truck. A dead battery can look like a short to many battery chargers and they won't charge. Shore power, if you have not tried it, may work but I don't know how the Iota behaves with a dead battery. You can try pulling the battery out and jumping it with your truck battery. Heavy duty battery cables and the truck alternator should be able to handle the current.
However, running a lead acid battery into the ground positively takes a big toll on battery life so you may just want to bite the bullet and go for a new battery. Avoid "marine" batteries and get only "deep cycle, AGM". I don't think AutoZone has what you need, but it looks like you can order one through Walmart. They have Universal Battery batteries which I have used in the past.
There's a lot of discussion on the site on battery choices

I would contact the battery manufacture, or FWC, and see if it will be covered under warranty. I'm not sure what the battery warranty covers but I have had auto batteries replaced at NAPA before when they have failed to hold a charge.

Before making a decision, check the camper main power switch. If it is off, the Iota won’t charge the battery.
Secondly, put a smart charger like a Noco Genius smart charger on the battery and leave it on overnight or until it indicates a failure.
I have had my G15000 recover a dead AGM that I thought was toast. The battery was on my ham gear during a week long outage after a storm and my other charger couldn’t bring it around. The Noco took 2 days but did revive the battery.
Good luck.

Took it to an autozone and even after charging it still didn’t test as charged. Had to buy a new one and learn a hefty lesson.
