GEB121 Batteries
GEB121 Batteries can be charged
using the GKL122 or GKL111 battery
chargers. The preferred model is the
GKL122.

GEB71 Batteries can be charged
using the GKL122 battery charger
only.
Chargers
The GKL122 is an intelligent charger.
It will charge the batteries by the
exact amount required. This maxi-
mizes battery life. The GKL122 can
charge up to 2 GEB121 batteries at
once. The GDI121 extension plate
enables a further two batteries to be
charged from the same charger at the
same time.
Additionally, the GKL122 can charge
up to two GEB71 batteries.
The GKL111 battery charger is a
simple charger. It will charge one
GEB121 battery at a time. It will
charge the batteries by the exact
amount required. This maximizes
battery life.
The batteries are delivered
from the factory totally
discharged. They will require a full
charging cycle before the equipment
can be used. For full instructions on
battery charging, refer to the manual
accompanying the charger you are
using.
