The average service life of auxiliary batteries is approx 2 years. Carryout a load test on your batteries and ensure your charging systems are functioning correctly.
Check all connections and grounding points for any corrosion or deterioration or looseness.
Please remember the following:
a. batteries need to be charged at regular intervals.
b. Prevent discharging your auxiliary batteries to less than 50% of their charge rate. This will deplete their recharge capacity and shorten their cycle life
