Removing/Installing Batteries From/Into Battery Tray - Invacare Pronto M71 Service Manual

SECTION 10—BATTERIES/CHARGER

Removing/Installing Batteries From/Into Battery Tray

ALWAYS use a battery lifting strap when lifting a battery. It is the most convenient
method and assures that the battery acid will not spill. It also helps to prolong the
life of the battery.
DO NOT tip the batteries. Keep the batteries in an upright position.
Place the wheelchair in a well ventilated area where work can be performed
without risking damage to carpeting or floor covering.
Some battery manufacturers mold a carrying strap and/or hold down flanges
directly into the battery case. Batteries which interfere with the battery box cannot
be used for these applications. Attempting to "wedge" a battery into a battery box
may damage the box and/or the battery.
NOTE: For this procedure, refer to FIGURE 10.2 on page 90.
NOTE: Have the following tools available:
TOOL
Battery Lifting Strap
1/2-inch (6 pt) Box Wrench
7/6-inch (6 pt) Box Wrench
3/8-inch (6 pt) Box Wrench
Diagonal Cutters
NOTE: If there is battery acid in the bottom of the battery tray or on the sides of the battery(ies),
apply baking soda to these areas to neutralize the battery acid. Before reinstalling the existing or
new battery(ies), clean the baking soda from the battery tray or battery(ies) being sure to avoid
contact with skin and eyes. Determine source of contamination.
NOTE: Never install/reinstall a battery with a cracked or otherwise damaged case.
NOTE: When securing battery lifting strap to battery, observe polarity markings located on the
ends of the battery lifting strap, (+) side to POSITIVE (+) battery post and (-) side to NEGATIVE
(-) battery post.
NOTE: Battery covers are used on wheelchairs manufactured BEFORE 7/14/03.
NOTE: Wheelchairs manufactured AFTER 7/14/03 DO NOT use battery covers.
