REMEMBER: Keep the batteries fully charged and avoid deeply discharging the batteries. Do not charge
for more than 24 hours.
How can I get maximum range or distance per charge?
Rarely will you have an ideal driving situation such as smooth, flat, hard terrain with no hills or curves. More often
you are presented with hills, footpath cracks, uneven and loosely packed surfaces, and curves. All of these factors
affect the distance or running time per battery charge. The following are suggestions for obtaining the maximum
range per charge:
n Always charge the batteries fully prior to your trip.
n Maintain 30-35 psi in pneumatic drive wheels.
n Plan your trip in advance to avoid inclines if possible.
n Limit the baggage weight to essential items.
What type of battery should I use?
We recommend deep-cycle batteries that are sealed and maintenance free. Both sealed lead-acid (SLA) and gel
cell are deep-cycle batteries and are similar in performance.
Use these specifications to reorder deep-cycle batteries:
Battery Specifications
Type: Deep-cycle sealed lead-acid or gel cell
Size: U-1
Voltage: 12V each
Amp Hours: 30-35 amp hours
Why do my new batteries seem weak?
Deep-cycle batteries employ a different chemical technology from that used in car batteries, nickel-cadmium
(nicads), or in other common battery types. Deep-cycle batteries are specifically designed to provide power, drain
down, and then accept a relatively quick recharge. Lead-acid batteries should be charged as often as possible.
They do not have a “memory” like nickel-cadmium batteries.
We work closely with our battery manufacturer to provide a battery that best suits the Jazzy 1143’s specific
demands. Fresh batteries arrive regularly and are promptly shipped with a full charge. During shipping, the batter-
ies encounter temperature extremes that may influence their initial performance. Heat robs the charge from the
battery, and cold slows the power available and extends the time needed to recharge the battery (just as with a car
battery).
It might take a few days for the temperature of the battery to stabilise and adjust to its new ambient temperature.
More importantly, it takes a few “charging cycles” (a partial drain—then full recharge) to establish the critical
chemical balance that is essential to the battery’s peak performance and long life. It is well worth it for you to take
the time to break in the batteries properly.
NOTE: The useful life of a battery is quite often a reflection of the care it receives.
