10 Tips to Extend RV Battery Life | How to Charge RV Batteries
This video from an RV expert will help you extend the life of your RV batteries.
With some basic care and maintenance, extending the life of the batteries in your RV is an easy task. In this video from RV expert Mark Polk you’ll learn just what to do to get the most out of your lead acid batteries.
Top Tips From This Video
Deep cycle lead batteries should last for six or more years with proper care and maintenance
Always keep safety in mind when working around lead acid batteries
Wear gloves and safety glasses
Remove all jewelry
Do not smoke or use open flames
The leading cause of dead lead acid batteries is extended sulfation which occurs when a battery’s charge drops below 80% or 12.4 volts
Sulfation can be prevented by recharging in a timely manner
Never let a 12-volt batter discharge below 12-volts or a 6-volt battery to fall below 6 volts
A fully charged 12-volt battery is actually 12.73 volts
A fully charged 6-volt battery is actually 6.37 volts
When a battery is at 12-volts it is at or below a 40% state of charge
Use a digital volt meter to check your level of charge
Reducing a battery’s depth of discharge will increase overall life
Parasitic loads – or items that run when the RV is not in use – can cause batteries to discharge
Hot temperatures and overcharging can also kill batteries so be sure to check water levels frequently
When adding water, make sure to use mineral-free water – distilled is best
Batteries should only be watered after charging a battery unless the plates are exposed prior to charging
The lead and plastics used to produce batteries can be recycled
