22.2 Replacing Backup Battery
The EXL6 has an advanced battery system that uses a rechargeable lithium-ion battery. The
battery powers the real time clock when power is removed. To store registers, the battery
continues to power the OCS for less than a second after external power is removed. In this time
the registers and other retentive data is saved to internal flash memory. This battery will need
about eight (8) hours of charging to last approximately two (2) years when powered off.
NOTE: For the registers to be retentive the battery only needs to be charged and present at
power down.
The battery will generally last seven (7) to ten (10) years. Environmental conditions, including
extreme temperatures and humidity, can affect battery life. If the battery is older than seven
(7) to ten (10) years old, it is recommended that it be replaced as preventative maintenance.
NOTE: Do not use an alkaline AA battery, only the proper battery type listed.
WARNING: DO NOT USE IF BATTERY IS LEAKING OR HAS BEEN DAMAGED.
WARNING: LITHIUM BATTERIES MAY EXPLODE OR CATCH FIRE IF MISTREATED.
DO NOT RECHARGE, DISASSEMBLE, HEAT ABOVE 100° C (212° F) INCINERATE, OR
PUNCTURE.
WARNING: EXPLOSION HAZARD
–
BATTERIES MUST BE ONLY BE CHANGED IN A AREA

WARNING: Disposal of lithium batteries must be done in accordance with federal, state, and
local regulations. Be sure to consult with the appropriate regulatory agencies
before
disposing batteries. In addition, do not recharge, disassemble, heat or incinerate lithium
batteries.
WARNING: Do not make substitutions for the battery. Be sure to only use the authorized part
