Discover® DRY CELL Solar Energy Storage batteries outperform traditional Flooded, AGM and Gel deep-cycle batteries and promotes resilience in on-grid and off-grid applications, particularly in regions with poor infrastructure and unreliable power. The batteries incorporate features to withstand Partial State of Charge (PSOC) operation and tolerate wide ambient temperatures.
DRY CELL Solar Energy Storage batteries are maintenance-free, safe, easy to use and are the economical choice for reducing energy cost and grid dependence.

Relation Between Charge, Voltage, and Temperature
- Due to self-discharge characteristics of lead-acid battery technologies, batteries should be charged within 6 months of storage to ensure optimum performance, prevent sulphation and permanent capacity loss.
- Charge profile recommendations correspond to battery voltages at 25°C (77°F). For temperatures below, adjust +5mVPC/°C (+3mVPC/°F). Temperatures above, adjust -5mVPC/°C (-3mVPC/°F). Temperature compensated charging helps ensure optimum battery runtime and life performance.
