External Battery Connection

All UPS models come with a robust internal battery
system; select models feature connectors (see
accept optional external battery packs (sold separately
from Tripp Lite) to provide additional runtime. Adding
external batteries will increase recharge time as well as
runtime. See battery pack owner's manual for complete
installation instructions. Make sure cables are fully
inserted into their connectors. Small sparks may result
during battery connection; this is normal. Do not connect
or disconnect battery packs when the UPS is running
on battery power.
If you connect any external batteries, set the Battery
Charge Level Switch (see
This will increase your UPS's charger output so the addi-
tional batteries charge faster. Note: the switch to the right
of the Battery Charge Level Switch is inactive and will
not affect UPS operation regardless of its position.
CAUTION! DO NOT set the Battery Charge Level Switch to the
down position without an external battery connected. There is a risk
of damaging the UPS's internal battery system.
