Charger
CONCEPT AND MAIN APPLICATIONS
Model DC18WA is a Makita charger developed specially for
charging new slide-style Li-ion batteries.
New Makita Li-ion batteries model BL1411G (14.4V-1.1Ah)
and model BL1811G (18V-1.1Ah) can be charged approximately
in 60 minutes. But the maktec band Li-ion batteries designed with
the same concept, model L1451 (14.4V-1.1Ah) and model
L1851(18V-1.1Ah) cannot be charged.

[1] -2. Replacing Varistor and Fuse
(1) If the cause of Battery charger trouble is the breakage of Varistor and Fuse, you need not replace
Charging circuit, but simply replace Varistor and Fuse.
Sign of Varistor breakage:
Cracks exists in the surface of Varistor.
Cause of Varistor breakage:
Charger is plugged in a power source of two times or more than the rated voltage of Varistor.
Note: If Fuse has burned out meanwhile Varistor is not broken, something else in Charging circuit is probably
causing the trouble. In this case, replace Charger circuit.
(2) Replace Varistor and Fuse. (Fig. 4)
Fig. 4
Varistor/ Fuse is soldered on Charging circuit.
Remove a broken Varistor/ Fuse with soldering iron.
