12V batteries generally last about 3 years in this application. Proper maintenance such as booster charging, and maintaining fluid level can extend battery life. Batteries lose over 1% of their charge per month if not charged. Battery fluid should be checked every 3 months, and filled to within 1 inch of top of battery. A solar charger can not recover to a full charge if battery is drained beyond 50%.
If battery seems low perform the following tests:
- Check specifications of battery– Lift requires at least 500 CCA with a reserve capacity of 160 Amp Hours.
- Capacity test the battery using a (a) Voltmeter and Hydrometer or (b)a Capacity Tester
- For a charged battery the Voltmeter should read over 12.5V and the Hydrometer should be over 75%
- For a charged battery the Capacity tester should read “OK” and over 12.5V
