OFF-BOARD CHARGER
To charge the batteries using the off-board charger:
1.Position your Jazzy next to a standard wall outlet.
2.Be certain the controller power is turned off.
3.Remove the run plug located on the electronics tray. This activates the inhibit function.
4.Plug the
5.Plug the charger into the wall outlet.
6.The ammeter indicates how much charge is needed to fully charge the batteries. Wait about a minute for the charger to warm up. The ammeter should move all the way up to 5 amps, then gradually move back down to 0 amps.
7.We recommend you charge the batteries for 8 to 14 hours. As the batteries charge, the ammeter needle will slowly drop to zero. When the batteries are fully charged, the needle vibrates on or about zero on the ammeter scale.
8.When your Jazzy’s batteries are fully charged, disconnect the charger cord from the wall outlet.
9.Disconnect the charger from the electronics tray.
10.Reconnect the run plug into its connector.
NOTE: If the run plug is not reconnected, your Jazzy will not operate.
BATTERY BREAK-IN
To break in new batteries for maximum efficiency:
1.Fully recharge any new battery prior to its initial use. This brings the battery up to about 90% of its peak performance level.
2.Operate your Jazzy throughout the house and yard. Move slowly at first, and don’t stray too far until you become accustomed to the controls and break in the batteries.
3.Give the batteries another full charge of 8 to 14 hours and operate your Jazzy again. The batteries will now perform at over 90% of their potential.
4.After four or five charging cycles, the batteries will top off at 100% charge and last for an extended period.
BATTERIES AND
How does the charger work?
The battery charger takes the standard wall outlet voltage of 120 VAC (alternating current) and converts it to 24 VDC (direct current). The Jazzy batteries use direct current to run your power chair. When the battery voltage is low, the charger works harder to charge the battery. This is why the ammeter initially reads five or more amps.As the battery voltage approaches full charge, the charger doesn’t work as hard to complete the charging cycle. This explains why the ammeter drops as it approaches a full charge. When the battery is fully charged, the amperage from the charger is nearly at zero. This is how the charger maintains a charge but does not overcharge the battery.
Can I use a different battery charger?
You should use the charger supplied with the Jazzy. It is the safest, most efficient tool to charge the batteries. We do not recommend using other types of chargers (e.g., an automotive battery charger). Your Jazzy’s charger will not operate after the batteries have been discharged to nearly zero voltage. If this happens, call your authorized Pride provider for assistance.
