How much do the batteries self-discharge?
The self-discharge of the Aquion AHI battery chemistry is closely related to the ambient temperature at
which the battery is being held. Aquion batteries should be held within the temperature range outlined
in the Product Specification Sheet (available on the Aquion Energy Customer Portal at
http://info.aquionenergy.com/customer-portal
). Aquion batteries exhibit the following capacity losses
due to self-discharge over the course of one (1) month:
at -5°C: <2%
at 10°C: 5%
at 30°C: 25%
at 40°C: > 35%
For the AHI battery chemistry, the capacity loss due to self-discharge is not irreversible. Capacity lost
over a month can be recovered simply by recharging the battery to 100% SOC.
