So on our last camping trip we realized that our batteries were not working properly. So i took them out and put them both on chargers. After being on the charger for two days i took them off and put them on the meter and realized that one of the two batteries had a bad cell. So now i have to replace both of them even though only one went bad but I'm not sure which way to go.
I have been looking at carquests NGT Extreme Batteries. They are an AGM Deep cycle style battery part number NG31 & NG34M both are made by Deka.
the NG31 has a reserve capacity of 190 and the NG34M has a reserve capacity of 120. the stock batteries only have a reserve capacity of 100
So both batteries would be better then the stock interstate batteries. My only problem is that the battery tray is to narrow for the NG31 so if i wanted to keep the battery tray i would need to stay with the NG34M but if i took out the tray and only used the battery box i could use the NG31 but then would need to find a way to secure them so they didn't push to door open on the side of the camper while traveling.
the NG31 cost's $230ea and the NG34M $157ea
we do a little bit of dry camping each year but we also have a Honda generator that we take with us when dry camping so I'm nor sure it is worth the extra expense of $145 for the NG31's over the NG34M's
And I'm not sure its worth going with two 6V batteries ether because i don't think i would have a reserve capacity higher then just buying two NG31 for a total reserve capacity of 380
So is it worth spending the extra money to have two NG31 for a reserve capacity of 380 or should i just save the cash and buy two NG34M's and have a reserve capacity of 240 which is still better then the stock interstate batteries that had a total reserve capacity of 200 together.
here is some pictures of the battery box
