Frequently Asked Questions
For traditional tubular lead-acid batteries, check and top up distilled water every 2-3 months, or as indicated by the water level indicators. Maintenance-free batteries do not require this.
Lead-acid inverter batteries typically last 3-5 years, while LiFePO4 batteries can last 8-15 years or more, depending on usage, maintenance, and DoD.
It is generally not recommended to connect batteries of different Ah capacities in the same bank, as it can lead to uneven charging/discharging and reduce the lifespan of individual batteries.
Inverter batteries should be kept in a cool, dry, well-ventilated area, away from direct sunlight and heat sources, to ensure optimal performance and lifespan.
The C-rating indicates the rate at which a battery can be safely discharged or charged relative to its capacity. For instance, a 1C rate means it can be fully discharged in 1 hour. This tool uses Ah capacity, which is simpler for typical inverter users.
While a smaller load will provide longer backup, there’s usually a minimum load required for the inverter to operate efficiently. Very small loads might not utilize the battery’s capacity optimally due to inverter’s self-consumption.
Ensure proper ventilation, secure connections, keep away from flammable materials, and ensure the battery is placed on a stable, level surface. Always follow the manufacturer’s guidelines.
