Handle Identification
Keeler C size and pocket handles are colour coded to allow you
to distinguish between a dry cell battery handle (2.8v) and a
rechargeable handle (3.6v).
The handles and Keeler bulbs are colour coded as follows:
Blue base = 2.8v for dry cell batteries.
Red base = 3.6v for rechargeable batteries.
Black base = LED for dry cell and rechargeable batteries.
Please ensure when replacing batteries and bulbs that the
voltage corresponds to the handle.
Disconnect from charger prior to removing instrument head.
Dispose of old batteries safely.

as shown on page 18.
Please note Keeler rechargeable handles are normally supplied
