in contact with skin, clothes or other possessions.
It is a form of acid and harmful or damaging
burns may result. Should the liquid touch your
skin, wash the area immediately and thoroughly
with cool water. In serious cases or if eye contact
is made, seek medical attention IMMEDIATELY.

NEVER smoke or strike a match near batteries. If
the caps of the battery cells are removed, NEVER
look directly into them while charging batteries.

NOTE: Allow eight (8) hours for normal charging. Larger
batteries (greater than 55 ampere-hours) or severely dis-
charged batteries may require up to sixteen (16) hours
to be properly charged and equalized. If the charger op-
erates for sixteen (16) hours and is unable to fully charge
the batteries, an internal timer turns the charger off and
begins to fast blink the green light.

NOTE: If the batteries need to be charged more often or
take longer to charge than normal, they may need to be
replaced. Contact an Invcare dealer for service.
