Your RV battery is generally out of sight and out of mind, which causes some RV owners to forget about one of the most important components of their rig completely.

But a little upkeep every 3 months can make a huge difference and extend your RV battery's life. Not only will it keep the batter up and running, but regular maintenance will reduce the cost of battery issues in the long run. Remember that prevention should always be of utmost importance with your rig.

Here are the 3 steps you need to follow to check and charge your RV battery:

1. Disconnect The Battery Leads

 

Remember to always remove the negative cable first. You'll want to do this to avoid any electrical damage to the battery and eliminate any chance of accidental sparks. Safety first is always the motto!

2. Check The Water Levels

 

If your battery has fill ports, top them off with distilled water (Do not use tap water as it can mess with the battery chemistry and cause major issues).

At Outrig, we also recommend if you're storing the battery to bring the battery indoors and set it somewhere cool and dry. Do not place the battery on a concrete floor as concrete can drain the battery faster.

3. Place The RV Battery On A Trickle Charger

 

Let the battery charge for a few days to keep the battery happy and healthy.

Before hitting the road next season, be sure to give it one more full charge just to be safe. No one wants to be stranded at their first campsite of the season!

 

Take care of your battery and it will take care of you.
