Batteries & Battery Charging
Batteries
The Shoprider PUMA Powerchairs are designed to operate on two
12 volt
sealed lead acid aka SLA (AGM or gel-cell type)
maintenance free batteries. The life of the batteries may be affected by
temperature, terrain, weight of user, driving methods, and care of batteries.
The active user will need to charge the batteries after using approximately
30% of battery capacity. As an inactive user, only using from once a week
to every other day, the recharge point would be at 50% of discharge (Refer
to Figure 8). For extended battery life, it is highly recommended that these
guidelines be followed. You cannot over charge the batteries.
*Keeping the batteries charged extends the life of the batteries*
SLA batteries should be kept fully charged at all times. They must not
be left in a discharged state if the unit is not being used for some time
or the batteries will be permanently damaged and will no longer hold
a charge. The SLA batteries should be checked once a month and
kept charged as needed. Typically SLA batteries have up to about
400 charging cycles.
