FAQ

Q1: How long does it take to fully charge this 260Ah battery?

A1: Using the recommended charge current (0.1C-0.2C, i.e., 26A-52A), it takes approximately 5-10 hours to charge from fully discharged to full. Using a higher-power charger can reduce this time, but ensure it does not exceed the battery's maximum charge current limit.

Q2: How is the 2000-cycle lifespan defined? How long can it actually last in practical use?

A2: A cycle refers to one complete process from 100% state of charge, discharging to the cut-off voltage, and recharging back to full. With one complete cycle per day, 2000 cycles correspond to approximately 5.5 years. In practice, with mostly partial cycles and proper maintenance, the actual service life can typically reach 8-10 years.

Q3: Are there any special requirements for installing and using such a high-capacity battery?

A3: Firstly, ensure the installation location is well-ventilated and has adequate load-bearing capacity. A compatible lithium battery charger (14.4V-14.6V charge voltage) is essential. Installing appropriately rated fuses or circuit breakers between the battery and load/charger is recommended. Regularly check that connection terminals are tight, and keep the battery surface clean and dry. For long-term storage, maintaining 50%-80% state of charge is advised.
