How long do RV batteries last in storage?

Generally speaking, RV batteries can last for several months in storage without being used before they begin to lose their charge. Lead-acid batteries, commonly used in RVs, can lose around 5-15% of their monthly charge when not being used or charged. Lithium-ion batteries, which are becoming more popular in RVs, have a slower self-discharge rate and can last longer in storage without losing their charge.

To extend the lifespan of RV batteries in storage, it’s important to properly maintain and prepare them before storing them. This includes fully charging the battery, disconnecting it from the RV’s electrical system, and storing it in a cool and dry location. It’s also a good idea to periodically check on the battery and recharge it as needed to prevent it from losing its charge completely. If you’re not sure how long your RV battery will last in storage, we recommend using a battery tender to keep it charged. This way, you can be sure that your battery will be in good working order when you take your RV out of storage.

The lifespan of RV batteries in storage can vary depending on a number of factors, such as the type of battery, the condition of the battery before storage, and the temperature and humidity of the storage environment.

Preparing an RV for storage is an important step in protecting it from damage and ensuring it’s ready to use when needed. Here are some steps to take when preparing an RV for storage:

  1. Clean the RV thoroughly, both inside and out. This includes emptying and cleaning out the refrigerator, cabinets, and storage areas and removing any food or other items that could attract pests.
  2. Drain the water system and hot water heater to prevent freezing and damage to the plumbing system.
  3. Remove any perishable items, such as food and toiletries, and store them elsewhere.
  4. Remove the battery and store it separately, in a cool and dry location, and away from any flammable materials.
  5. Cover the RV with a breathable cover to protect it from the elements and to prevent moisture buildup.
  6. Check the tire pressure and add air if necessary. You may also want to consider using tire covers to protect the tires from the sun and weather.
  7. Fill up the fuel tank and add a fuel stabilizer to prevent the fuel from breaking down and causing damage to the engine.
  8. Close and lock all windows and doors to prevent pests and intruders from entering the RV.
  9. Consider using moisture absorbers or a dehumidifier to prevent moisture buildup inside the RV, which can lead to mold and mildew.


By taking these steps to prepare your RV for storage, you can help ensure that it stays in good condition and is ready to use when you’re ready to hit the road again.
