Battery Maintenance Guideline
The Xantrex Lithium-ion Battery 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 following 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 Battery 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
* For long term duration storage the battery should be kept in a particular charged state such as, 13.2V, ~50% SoC, and stored at the recommended storage specifications shown above.
Storage Instructions for Short Durations
1. Fully charge the battery.
2. Turn off the battery (see
).
3. Keep the battery in an environment according to
Battery Maintenance and Storage Specifications
.
Storage and Maintenance Instructions for Long Durations
1. Reduce the battery state-of-charge (SoC) to 50% ±10% which is approximately 13.2V for a 12V battery or 26.4V for a 24V
battery .
2. Turn off the battery (see
).
3. Keep the battery in an environment according to
Battery Maintenance and Storage Specifications
.
4. Every six months maintain the battery by charging it to 100% SoC, then discharging the battery to low voltage cutoff (LVC)
level, then charging it back to 50% ±10% SoC.
NOTICE
RISK OF BATTERY DAMAGE
Do not charge the battery in ambient temperature below freezing.
Failure to follow these instructions can result in damage to the battery and may void the
warranty.
