e. The temperature of the battery card assembly is generally 15–20 degrees higher than the ambient
temperature during fast charge. Therefore, to complete fast charge cycle, the ambient temperature
should be less than 45 degrees. If the ambient temperature exceeds 45 degrees, the fast charge
cycle will terminate prematurely, thus preventing the battery card assembly from reaching a fully
charged state.
Attention:
When attaching the battery card assembly to a PCI Express slot, center the Phillips-head screw
driver to avoid damaging the screw head and do not over-tighten the screws as you might damage
the battery card assembly.
The battery in the battery card assembly must recharge for at least six hours during fast charge
under normal operating conditions.
