- Fast charg ing a battery is dangerous and
should only be attempted by a compe­
tent technician w ith the proper equip ­

of warm water and ba kin g soda to neu­
t rali ze the acid.
~ Note
Never use a fast charger as a booster to
start the engine. This will seriously dam ­
age sensitive ele ct ronic components, such
as co ntrol units, relays, rad io, etc. , a s we ll
