6. BATTERY CHARGING & CARE

Suggestion – 

How to maximize your battery’s efficiency and service life

1.  

Fully charge any new battery before its initial use.

2.

  Be sure to charge the battery fully every time. Battery life will be seriously 

diminished if the battery is repeatedly used without being fully charged.

3.

 Always complete the charging until the red LED light turns green.  

NEVER stop charging before it is complete.

4.

  Keep your batteries fully charged whenever possible.

5.

  If the power chair is not used for an extended period, batteries should be 

charged at least weekly to keep them fully usable.

6.

  The ambient temperature affects charging time, it will be longer  

in the winter. 

7.  

After charging, do not leave the charger socket plugged into the power 

chair as this will cause a power drain and temporarily reduce range.

Charging the batteries off-board using the charger
The Crest CSS has a removable battery box. 

1. Remove the Seat
2. Lift the battery box out of the shroud and take this to the closest power outlet.  

Plug the charging cable into the wall outlet and connect to your battery box.

3. When your batteries are fully charged, unplug the charging cable from the  

wall outlet.

Cleaning the battery
If the batteries are contaminated by water, battery acid, dust or other substances, they 
will discharge quickly. The batteries supplied with the power chair are sealed and as

3.  Remove the battery box from the Crest CSS shroud. 
4.  Remove the screws from the underneath of the battery box to open the battery  

box unit.

5.  Use a clean cloth to wipe off the soiled area.
6.  Remove the battery.
