Compact Series Backup Batteries
The PXC Compact Series contains one non-rechargeable AA (LR6) battery and one
non-rechargeable coin cell (BR2032) battery that serve as a power backup in the event
of a power failure. The batteries only discharge during a power loss. They do not
recharge.
CAUTION
Only use a 3.6 Volt lithium battery in PXC Compact models with extended
temperature range operation.
Only use a 1.5 Volt alkaline battery in standard PXC Compact models.
• The 3.6 Volt lithium battery is designed to operate at both high and low temperature
extremes, and it provides a long service life in an extended temperature environment.
• The 1.5 Volt alkaline battery is not guaranteed to provide backup protection in
models with extended temperature range operation, even if the controller is operating
in a room-temperature environment.
• If a 3.6 Volt lithium battery is used in standard PXC Compact models, the battery
quickly discharges and provides much less backup protection than a 1.5 Volt alkaline
battery.
