Battery Purchase

In that case, either switch to hydronic and/or catalytic heat, and/or switch to a battery designed to handle rv loads. Buying yet another marine hybrid is chasing bad money with good, imo.

But first call the rv manufacturer, and ask them what the #*// they were thinking?

Sell that hybrid to a boater, consider it a lesson learned, and just move on.

Add another similar battery. Mismatching batteries isn't as critical as some believe. Connect in a balanced manner as Don instructed.

Lights aren't the problem. On a cool/cold night, the furnace will take the current battery below 50%.

Do nothing. Use the existing battery to the max. Get a new set up for the next season.

Spend the money on LED bulb replacements and/or 100 watts of solar.

Changing to LED bulbs is just as good as getting a second battery: And they will be forever!!

Do not throw the battery away... buy a boat, instead, :)

If going to another battery, try to match as closely as possible.

My biggest battery saver when I started boondocking....LED bulbs AND energy management. It's cheaper to conserve than to buy more.

My experience with marine/deep vs true deep cycle is that they will sometimes get pretty lazy. It all gets into charging, equalizing etc. Bottom line is check your specific gravity. There are tons of posts by sketter, bfl, mex, niner, roy, landy, etc sorry to not remember more at the moment.

Point is you need to know what is happening with your battery vs converter output and length of charges. It's deep but it's also not deep. It just all matters though. More battery could result in more dead battery.

Instead of another battery you may even go to a small gen. Manage your times such as microwave use, hair dryer etc and run those things while also charging.

Get yer wallet out, ya just got started. :)

This is what is balanced and best for twin twelve volt batteries.



As it often doesn't cost a dime more to do this, I think it is worth the trouble.

If you wish to understand the "why" surf here:

correctly interconnecting multiple twelve volt batteries

Others may say it doesn't matter--but unless there is a compelling reason to not optimize charging and discharging why not do it the best possible way?

Yes, pair it with an identical battery. You don't go off-grid much so no need to do more than that.

A 12v true deep cycle like the T-1275 can be paired with the hybrid but they are not a good match in parallel.

I would match the original battery up.
