Why do my new batteries seem weak?
Deep-cycle batteries employ a different chemical technology than is used in car batteries, nickel-cadmium
batteries (nicads), or in other common battery types. Deep-cycle batteries are specifically designed to pro-
vide power, drain down their charge, and then accept a relatively quick recharge.
We work closely with our battery manufacturers to provide batteries that best suit your scooters specific
electrical demands. Fresh batteries arrive daily at Pride and are shipped fully charged to our customers.
During shipping, the batteries may encounter temperature extremes that may influence their initial perfor-
mance. Heat will diminish the charge on the battery; cold will slow the available power and extend the time
needed to recharge the battery.
It may take a few days for the temperature of your Shuttles batteries to stabilize and adjust to their new
room or ambient temperature.
More importantly, it will take a few charging cycles (a partial drain followed by a full recharge) to establish
the critical chemical balance that is essential to a deep-cycle batterys peak performance and long life.
Follow these steps to break in your Shuttles new batteries for maximum efficiency and life.
1. Fully recharge any new battery prior to its initial use. This charging cycle will bring the battery up to
about 88% of its peak performance level.
2. Operate your new Shuttle in familiar and safe areas. Drive slowly at first, and do not travel too far from
your home or familiar surroundings until you have become accustomed to your Shuttles controls and
have properly broken in your scooters batteries.
3. Fully recharge the batteries. They will now be at over 90% of their peak performance level.
4. Operate your Shuttle again.
