How to Get More Life Out of Your RV Battery

March 11, 2019

RVers often wish they could get a bit more life out of their RV battery. In some cases only lasting a season or two, there are ways to keep your battery kicking longer. Our resident RV expert, Mark Polk, offers five tips to make your RV lead-acid batteries last longer and help you stay on the road.

Top Tips From This Video

  • Properly maintained deep-cycle lead-acid batteries should last for six or more years
  • The leading cause for dead lead-acid batteries is sulfaction caused by crystals that form on the plates during periods of low charge
  • Reducing a batteries depth of discharge will increase the life of a battery
  • Overcharging a battery can also decrease a battery’s life
  • When it’s hot or you’re using the battery more you need to check and maintain water levels more often
  • RVs have parasitic loads, such as stereos and appliance circuit boards, that can discharge a battery so make sure you utilize your battery disconnect switch or disconnect the negative battery terminal when not in use
  • Batteries self-discharge when sitting idle so keep this in mind
