How long can I leave the wheelchair batteries without charging?

All Lead acid batteries get slowly discharged on open circuit called self discharge.  During discharge the battery voltage will slowly decrease.  When the voltage reaches below certain voltage it can permanently damage the battery and may not be able to recharge. 

When the battery is fully charged and left with out recharge for about six months at 77F, can be recharged back. 

Higher temperatures accelerate the discharge rate. This means when a Lead acid battery is left on open circuit at higher temperature have to be recharged sooner than 6 months. 

When the batteries are not fully charged the voltage is already low the batteries have to be recharged soon.  Never leave a fully discharge lead acid battery with out recharge for a long time. 

If you are leaving on a long trip, fully charge the batteries before you leave.  Don't forget to unplug the batteries from the charger.

Over charging the lead acid batteries can cause the batteries to loose water from the electrolyte   Loosing water can reduce the life of the batteries. Unplug the charger after the battery is fully charged.  Avoid leaving the batteries on charge for extended period of time.  If you still have questions feel free to contact us at (877)394)3941.
