How do I change a battery?
WARNING! Battery posts, terminals, and related accessories contain lead and
lead compounds. Wear goggles and gloves when handling batteries and wash
hands after handling.
WARNING! Always use two batteries of the exact same type, chemistry, and amp
hour (Ah) capacity. Refer to the specifications table in this manual and in the
manual supplied with the battery charger for recommended type and capacities.
WARNING! Do not mix old and new batteries. Always replace both batteries at
the same time.
WARNING! Contact your Pride Provider if you have any questions regarding the
batteries in your PMV.

Why do my new batteries seem weak?
Deep-cycle batteries employ a different chemical technology than that used in car batteries, nickel-cad-
mium batteries (nicads), and other common battery types. Deep-cycle batteries are specifically designed
to provide power, drain down their charge, and then accept a relatively quick recharge.
We work closely with our battery manufacturer to provide batteries that best suit your PMV’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 can influence their initial perfor-
mance. Heat diminishes the charge on the battery; cold slows the available power and extends the time
needed to recharge the battery.
It may take a few days for the temperature of your PMV’s batteries to stabilize and adjust to their new
room or ambient temperature. More importantly, it takes a few charging cycles (partial draining followed
by full recharging) to establish the critical chemical balance that is essential to a deep-cycle battery’s peak
performance and long life.
