n Try to maintain an even speed while your Dynamo is in motion.
n Avoid stop-and-go driving.
What type and size 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 that are similar in performance in your Dynamo. Do not use wet-cell
batteries, which have removable caps.
NOTE: Do not remove the caps from sealed batteries. Water cannot be added to sealed batteries. Cap
removal voids the battery warranty and may cause damage to the batteries and to your Dynamo.
Use these specifications to reorder deep-cycle batteries:
Type: deep-cycle (sealed lead-acid or gel cell)
Size: U-1
Voltage: 12 volts each
Amperage: 32 AH (amp hours)
To change a battery in your Dynamo:
1. Remove the seat and the rear shroud. See IX. Disassembly and Assembly.
2. Disconnect the battery cables from the electronic controller assembly.
3. Disconnect the battery cables from the battery terminals.
4. Remove the old battery.
5. Place a new battery in the battery well.
6. Connect the red battery cable to the positive (+) battery terminal.
7. Connect the black battery cable to the negative (-) battery terminal.
8. Reconnect the battery cables to the electronic controller assembly.
9. Reinstall the rear shroud and the seat.
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 manufacturer to provide batteries that best suit your Dynamos specific
electrical demands. Fresh batteries arrive daily at Pride and are shipped fully charged to our customers. Dur-
ing shipping, the batteries may encounter temperature extremes that may influence their initial performance.
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 Dynamos batteries to stabilize and adjust to their new
room or ambient temperature.
