How Long Does It Take to Charge an RV Battery
While there is no universal rule dictating exactly how long it takes for charging an RV battery
https://www.renogy.com/blog/effectively-charge-your-rv-batteries-while-driving/ to charge, you can generally expect this process to take 10 hours at a minimum – and maybe 40 hours (or more) for the battery to reach a 100% charge.
As we mentioned a second ago, a lot of this has to do with the size of the battery, the type of the battery, how much juice really was left in that battery before you tossed it on a charger, and more.
Even the kind of charging system you are using will have a major impact on how quickly this process is going to take.
Just remember that at the very least it’s going to probably take 10 hours to get your battery a halfway decent charge. It might take four times as long (up to 40 hours or longer) in certain situations.
12v (Group 24)
It’s not super common for RV batteries to come in this variety, but some of the older RVs on the road today (especially some of the smaller ones) may have this kind of battery tucked inside.
This battery is going to require a minimum charge time of about 4 to 5 hours. You can speed things up a little bit by keeping the battery plugged into a trickle charger whenever it isn’t in use, but other than that you’re looking at a relatively short charging timeline (at least as far as RV batteries are concerned).
12v (Group 27)
These batteries have a bigger capacity and are a little more powerful, offer a little more range, and are generally going to need a little more time to get up to a full charge.
These batteries are going to need at least 10 hours (sometimes 12 or more) to go from completely dead all the way up to a minimum baseline. They can then continue to charge while “on the go”, though that may or may not be something that you are capable of doing while you are traveling around.
You find a lot of these batteries in RVs that have a little bit of sized them (midsized units, really), though the really big RVs usually go with a bigger battery.
12v (Group 31)
This is the kind of battery that you can find in really big RVs, a battery that is going to require at least 15 hours to charge to a minimum level – and then will need anywhere between 25 and 30 (or more) hours to get up to a full charge from there.
Dual 6v Batteries
Some people like to run dual 6 V battery configurations in the RVs that they are traveling around it. This provides a little bit more “autonomy” – allowing you to break your power bank into 26 both sections as necessary – but both batteries will have to be charged up independently.
The thing about these batteries is that they are going to take a long time to charge, even when you are using faster chargers that can pump out 25 A.
Charging on a traditional five amp charger is going to take you 25 to 30 hours (maybe a little bit longer than that). You can speed things up quite a bit by throwing these dual batteries on a 25 amp charger – but even then you’re still looking at more than seven hours of charge time just to get up to a baseline level.
