RV Battery Life Expectancy

The life expectancy of your RV batteries depends upon you. How they’re used, how nicely they’re maintained, how they’re discharged, how they’re re-charged, and the way they’re saved all contribute to a batteries life span. A battery cycle is one full discharge from 100% all the way down to about 50% after which re-charged again to 100%.

One necessary issue to battery life is how deep the battery is cycled every time. If the battery is discharged to 50% on a regular basis it should final twice so long as it could if it is cycled to 80%. Preserve this in thoughts when you think about a battery’s amp hour score. The amp hour score is absolutely reduce in half since you do not need to fully discharge the battery earlier than recharging it. The life expectancy depends upon how quickly a discharged battery is recharged. The earlier it’s recharged the higher.

What does all of this imply to you? That depends upon how you utilize your RV. If most of your tenting is finished the place you are plugged into {an electrical} supply then your most important concern is simply too correctly preserve your deep cycle batteries. However if you happen to actually wish to get away from all of it and also you do some severe dry-camping you may need the very best amp hour capacities you possibly can match in your RV.

Deep cycle batteries are available in all completely different sizes. Some are designated by group measurement, like Group 24, 27 and 31. Principally the bigger the battery the extra amp hours you get. Relying in your wants and the quantity of house you could have obtainable, there are a number of choices in the case of batteries. You should use one 12-volt Group 24 deep cycle battery that gives 70 to 85 amp hours or you should utilize two or extra 12-volt batteries wired in parallel. Parallel wiring will increase amp hours however not voltage.

When you have the room you are able to do what quite a lot of RVers do and change from the usual 12-volt batteries to 2 of the bigger 6-volt golf cart batteries. These pairs of 6-volt batteries must be wired in collection to supply the required 12-volts. Collection wiring will increase voltage however not amp hours. If this nonetheless does not fulfill your necessities you possibly can construct bigger battery banks utilizing 4 6-volt batteries wired in collection/parallel that will provide you with 12-volts and double your AH capability.

Glad Tenting,
