Battery charging

NOTE
• Refer to the instruction in the Operation Manual for the Honda Battery Tester and Christie Battery Charger for detailed bat-
tery charging steps.
After activation, both conventional and maintenance-free batteries must be charged at the appropriate ampere-hour rating for
the proper length of time.
Set the Battery Amp. Hr. Selector Switch on the Christie Charger (#MC 1012/2) for the size of the battery being charged. Set
the Timer to the NEW ВАТТ position and connect the battery clamps. When the timef reaches the "trickle" position, the
charging cycle is complete.

Battery Charging/Testing equipment

The Christie Battery Charger (#MC 1012/2) is a constant current (amperage) type designed to produce current at a constant
rate for the duration of the charge, even if the voltage varies.
The Honda Battery Tester {07GMJ—0010000} puts a " l o a d " on the battery so that the actual battery condition at the time of
the load can be measured. This provides an accurate determination of the battery condition — good Igreen), fair (yellow), or
poor (red).
