alternative to using an uninterruptible power supply, and a second level of fault tolerance when used in conjunction with an uninterruptible power supply.

The temperature of the TR 700 Battery is generally 15-20°C (59-68°F) higher than the ambient temperature during fast charge. Therefore, to complete a recharge cycle, the ambient temperature should be lower than 55°C (131°F). If the ambient temperature exceeds 55°C (131°F), the recharge cycle will terminate prematurely, thus preventing the TR 700 Battery from reaching a fully charged state. A recharge cycle lasts at least six hours under normal operating conditions.

Attention: It is recommended that you replace the TR 700 Battery annually or after 500 recharging cycles, whichever comes first.
