Charge Cycles Disclaimer: The information provided regarding the life cycles of Enerdrive | Dometic lithium batteries is based on laboratory testing conducted under controlled conditions. These tests were carried out at a consistent temperature of 25°C, with discharge and charge rates set at 1C (1 x Capacity of battery). Under these specific conditions, it has been calculated that our lithium batteries can achieve over 2500 cycles with approximately 80% of original capacity remaining. However, it’s essential to note that actual performance may vary depending on various factors, including but not limited to, installation environment, temperature fluctuations, and variations in discharge and charge rates. It is recommended to avoid excessive discharges and charge cycles and to maintain a discharge and charge rate around 0.5C (0.5 x Capacity of battery) for optimal battery longevity. Doing so may result in a significantly higher cycle count. Please be aware that the numbers provided are based on cell-level testing and may not directly reflect the performance of your specific battery installation. As such, we advise users to consider their individual circumstances when assessing the expected lifespan of their batteries. Even in the scenario of reaching 2500 cycles, it’s important to understand that the lifespan of the batteries can extend beyond this figure. For instance, if batteries were fully discharged daily, a lifespan of over 6.8 years could still be expected. If you don’t normally take the battery under normal use below 30% SOC, then you could find that the battery will continue to meet your needs for many cycles to come. For further guidance on maximising the performance and longevity of Enerdrive | Dometic lithium batteries, please consult our technical support team or refer to the user manual.
