In case a battery (normal condition or damaged) needs disposal or needs recycling, it shall follow the local recycling regulation (i.e. Regulation (EC) Nº 1013/2006 among European Union) to process and using the best available techniques to achieve a relevant recycling efficiency.

Storage, maintenance and expansion

It is required to perform one full cycle (charging and discharging) every 6 months. For this charge maintenance make sure the SOC is charged to higher than 90%.
It is required to charge the batteries to SOC 100% at least once a month to recalibrate the SOC.
Every year after installation, the connection of power connector, grounding point, power cable and screws are suggested to be checked. Make sure there is no loose, no broken, no corrosion at connection point. Check the installation environment such as dust, water, insect etc. Make sure it is suitable for IP20 battery system.
A new battery module can be add onto an existing system at any time. Please make sure the new battery is acting as the master. The new module, due to a higher SOH may have a difference on SOC with existing system, but it will not affect the parallel connection system performance. It is recommended that the new battery at the time of connection has the same SOC as the existing batteries.
