WARNING
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.
NOTE: If there is battery acid in the bottom or on the
sides of the battery box(es) or battery(ies), apply bak-
ing soda to these areas to neutralize the battery acid.
Before reinstalling the NEW or existing battery(ies),
clean the baking soda from the battery box(es) or
battery(ies).
NOTE: When securing battery lifting strap to battery, ob-
serve polarity markings located on the ends of the battery
lifting strap, (+) side to POSITIVE (+) battery terminal/
post and (-) side to NEGATIVE (-) battery terminal/post.
1. If necessary, remove the battery boxes from the
wheelchair. Refer to
INSTALLING/REMOVING BAT-
TERY BOXES in this procedure of the manual.
2. Secure the battery lifting strap to battery terminal(s)/
post(s) (FIGURE 1).
CAUTION
Some battery manufacturers mold a carrying strap
and/or hold down flanges directly into the bat-
tery case. Batteries which interfere with the bat-
tery box cannot be used for these applications.
Attempting to “wedge” a battery into a battery
box may damage the box and/or the battery.
3. Place batteries into battery box bottom.
