RV Battery test and life check - My Daily RV Life -

RV Battery test and check When checking an RV battery, you can test the voltage. A good RV battery should have at least 12.7 volts. If it has less than that, it needs to be replaced or recharged. Healthy RV batteries will have between 12.4 and 12.8 volts. The life expectancy of an RV battery depends on the type of battery and how it’s used. Properly maintained deep-cycle batteries can last for six years or more. However, some RV owners replace their batteries every year or two. The three types of RV batteries are: Flooded lead-acid batteries, which have the shortest lifespan Lithium batteries, which have the longest lifespan AGM batteries, which can last between eight months and eight years A 12v battery can last two to three days under normal use conditions. You can extend the battery’s life by: Adjusting power usage Conserving water Shutting off lights Upgrading or adding extra batteries A good rule of thumb is to replace your RV battery about once every five
