SECTION 8—BATTERIES

Basic concepts which will help you understand this automatic process are:
The amount of electrical current drawn within a given time to charge a battery is called
“charge rate”. If, due to usage, the charge stored in the battery is low, the charge rate is
high. As a charge builds up, the charge rate is reduced, and the battery charger rate
decreases to a “trickle charge”.
NOTE: If the batteries need to be charged more often or take longer to charge than normal, they
may need to be replaced. Contact a qualified technician.
