Cleaning Battery Terminals - Invacare Xterra GT Service Manual

SECTION 8
2. Plug the charger’s AC power cord, or extension, into the grounded 120 VAC wall outlet.
3. Wait until charging is complete.
NOTE: Allow eight (8) hours for normal charging. Larger batteries (greater than 55 ampere-hours) or
severely discharged batteries may require up to sixteen (16) hours to be properly charged and equal-
ized. If charger operates 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: It is advantageous to recharge frequently rather than only when necessary. In fact, a battery’s
life is extended if the charge level is maintained well above a low condition.
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 Invacare dealer for service.

CLEANING BATTERY TERMINALS

Most batteries are not sold with instructions. However, warnings are frequently
noted on the cell caps. Read them carefully.
DO NOT allow the liquid in the battery to come 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.
1. Examine battery clamps and terminals for corrosion.
2. Verify the plastic caps are in place over battery cell holes.
3. Clean terminals and inside battery clamps by using a battery cleaning tool, wire brush, or
medium grade sand paper.
NOTE: Upon completion, areas should be shiny, not dull.
4. Carefully dust off all metal particles.
