A well-maintained inverter battery can last 5–7 years. A neglected one might fail within 2–3 years. The good news? Battery maintenance is simple and takes only a few habits.
For non-sealed (flooded) batteries, check the electrolyte water level every month. It should always be between the minimum and maximum markings. Use only distilled water — never tap water, which contains minerals that damage battery plates.
Terminals corrode over time, increasing resistance and reducing performance. Clean every 3 months using a paste of baking soda and water, then rinse and dry. Apply a thin coat of petroleum jelly to prevent future corrosion.
Frequently discharging to near-zero significantly shortens lifespan. Most Comfort Battery models work with inverters set to an 11.5V cutoff — this protects against damaging deep discharges.
Batteries emit hydrogen gas during charging. Always keep your battery in a well-ventilated area — never in a sealed cupboard. Keep it away from open flames and sparks at all times.
Before first use, always complete a full initial charge as per the manufacturer's instructions. This sets the battery's capacity baseline and extends long-term performance.
Get your battery professionally inspected once a year. A technician can check specific gravity, identify sulfation, and top up electrolyte correctly. Comfort Battery offers after-sales service through our dealer network.
