12 volt batterie

[bob213]

TT came with 2 12v batteries. We very seldom boondock. It's time to replace batteries. Want to stay with 12v. Any suggestions?

Although if you regularly draw down any deep cycle battery more ~ 50%, particularly flooded, you can expect total life will be greatly reduced. However, the OP indicates the only time he may rely on battery power as being those few times he may overnight in a WalMart parking lot while on his way to a destination where he would have shore power available. For him, as for myself, depth of discharge or achieving maximum cycle life from a deep cycle battery is moot as the battery will die of old age long before it ever sees it's maximum rated cycle life. Just about any 12 volt battery would serve his purpose just fine.

That is because terms like marine, trolling, deep cycle,... are marketing mumble speak.

What you want is the type of battery that meets your usage pattern.

An SLI, or starting, battery is designed for many 10% discharges with immediate recharge via the alternator being the pattern.

A deep cycle battery is designed for discharges which may accumulate to 80% over a period days before recharging.

A UPS battery is designed to be quickly and completely discharged by 100%, or to 10.5V, and then recharged slowly.

IMHO and YMMV.

Virtually ANY 12 volt battery would do for the OP, even a starting battery. Heck, I for years never even had a battery of any type on our Fleetwood popup as it wasn't required in it's weight class to even have brakes. Some who own a travel trailer with electric brakes but never camp without shore power may not even need a basic G24 deep cycle battery, just something to power the trailer brakes' breakaway system, such as this 5 AH SLA Battery sold specifically for this purpose.

Even 1 cold nite on a WM parking lot can use 2 batteries.

So walk in and pick up the second right there when needed 😉

several types of 12 volt batteries.

starting, like for a car
trolling, Deep cycle
deep cycle, but not really, rv store types.

the design of each is different... for a reason. look it up.

Are you also "mystified" as to why golf cart batteries are recommended too ? Most RVs don't qualify as a golf cart.

It is because they are designed for "deep cycle" use and are much less likely to be harmed if you DO get in a situation where they will be run near to dead.

Clearer now ??

Probably because if its designed for a trolling motor, it will surely handle anything an RV can give it,.......make sense ?

Thanks everyone!

IF you have the headroom (They are a bit taller) Do give consideration to going with a pair of GC-2 Six volt.. best price is at Sam's Club..

REASON.. Setting aside the features of the six volt pairs over a 12 volt pair for a moment.

The result may well be LESS EXPENSIVE.. that's right.. Often you can get a pair of sixes for less than a pair of 12's.. how's that for an argument in favor of them?

But do comparison shop

Now if you want to know the other advantages and disadvantages we can discuss.. But I went with sixes.

Many battery cases for a G24 battery use a spacer in them. It may hold a G27 (12.1" long) or G29 (13" long) battery. And a G27 is only a few $$ more than a G24.
