Want a "bigger" battery but where to put it?

Wow ... thanks for all the responses! Lots to think about.

1. I have a WFCO 50A, supposedly it's a 3 stage charger which, depending upon what I read, it may or may not be up to the job because it's just a plain 'ol factory installed distribution/charging unit.

...

3. I need to measure for "exactness" but, without modifications, I don't think I can get a longer battery in the same location. I can go taller and maybe wider but not longer.

4. From what I'm reading, since I can put a AGM in a non-vented area, a AGM in the storage compartment (under our bed) might be the way to go????

Thanks again,

John

1. Model #?

I have an 8735 that that likes 13.6V. I have never seen it charge at 14.4V. Even if it did, it would drop back to 13.6V as soon as the battery gets to 14.4V. Any charger that cannot hold 14.4V during charging is a poor choice to use with a genny.

If you are going to depend on a genny for charging, consider a PFC corrected charger that also has a temp-comp cable to read battery temps. PFC will reduce fuel usage and the temp-comp feature will charge faster because it will manage charging Volts better.

3,4. AGMs can be placed on a side or end. This gives you flexibility when looking at battery dimensions. I have a Johnson Controls 31C 100AH AGM on its side under the rear seat in the van; no venting.
