Battery Maintenance Guideline

The Xantrex Lithium-ion Batteries system is designed to require the least amount of maintenance as possible. The battery and internal BMS are contained in a sealed device and do not require disassembly for maintenance reasons. In general, to properly maintain the battery, follow the storage guidelines in the previous sections. If the battery/ies are in regular use, then it is recommended that the battery/ies be fully charged a minimum of once per two weeks in order for the BMS to recalibrate its State of Charge (SoC) setting. This process also ensures that the SoC meter maintains its accuracy.

Battery Storage Guidelines

In order to keep your Xantrex Lithium-ion Batteries at peak performance and at its healthiest state, you have to store it according to proper storage conditions and also maintain it with proper care.
Storage can be short term, such as less than one month or long term, such as more than six months. Table 2 Storage specifications
