How to Maximize the Lifetime of Your Lead-Acid Battery
To keep your charger fan running smoothly for years, follow these simple maintenance habits:
- The Initial Charge: When you first unbox your unit, plug it into an AC outlet and let it charge uninterruptedly for 12–15 hours before turning it on via battery power.
- Avoid Deep Discharge: Try not to run the fan until the battery is completely dead. Plug it back in to charge as soon as you notice the fan speed beginning to drop.
- Off-Season Storage: Don’t leave the fan completely neglected during the cold winter months. To keep the cell healthy, plug it in and give it a full charge at least once every 4 to 5 weeks.
