Batteries & Battery Charging
Batteries
The Shoprider Trooper Powerchair is designed to operate on two 12
volt/36Ah sealed lead acid (AGM or gel-cell type) aka SLA
maintenance free batteries. For easy handling, the SLA batteries are
contained within a battery-pack. The life of the batteries may be
affected by temperature, terrain, weight of user, driving methods, and
care of batteries. The battery gauge (Refer to Figure 3) is a guide on
the remaining charge of the 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 10). 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 “charging space” within the batteries will be permanently lost
(memory loss). The SLA batteries should be checked once a month
and kept charged as needed. Typically SLA batteries have up to
about 400 charging cycles.
