This manual contains safety and operating instructions for the RRP-431
Single Port and RRP-432 Dual Port chargers for Redi-Pak and SmartPack
battery packs. Before using this charger, please read all of the instructions
for both the charger and also for the battery pack to be charged.
®
™
To reduce the risk of injury, charge only 12V 5-20 Ahr RediPak /
SmartPack battery packs. Do not charge non-rechargable batteries.
®
Other types of batteries might burst the casing causing personal
injury or other damage!
Do not disassemble the charger. Opening the charger will void the
warranty and can result in risk of electrical shock or fire.
Never operate the charger with a damaged cord or plug. Use only the cord
supplied with the charger. Inspect both input and output cords for damage
before using charger.
Never unplug a cord by pulling on the cord itself. Always grasp the plug
when disconnecting the charger.
For indoor use only. Do not expose the charger to rain, snow, or excessive
moisture.
Three stage charge cycle
Battery manufacturers recommend using multi-stage charging to reduce the stress
on the battery while giving the shortest possible charge time. The RRP-431 /
RRP-432 series chargers implement the ideal charge cycle by applying a
Constant-Current charge for 70%-80% of the charge cycle and a Constant-Voltage
charge for the remaining 20%-30%. This is done to prevent the battery from
gassing as it approaches full charge, thus extending the usable life of the battery.
Once the battery has achieved it's optimal charge level, the charger will maintain
the charge using a Pulsed-Current float charge.
Thermal Compensation
In order to obtain maximum service life of the battery pack, a temperature sensor
built into the charge connector monitors the overall temperature of the battery
pack. The optimum terminal voltage for the charging process is dependant on
battery temperature. As the temperature of the battery pack rises, the charging
voltage is reduced to prevent over charge. As the temperature falls, the charge
voltage is increased to avoid under charge. If the battery pack temperature
exceeds 120 F,the charger will stop charging the battery pack and the STATUS
light will report an over temperature error. Once the battery pack temperature
falls back into the acceptable range, the charger will resume charging the battery.
Charging Process
1. Plug in and turn on the charger. The STATUS light will flash: [MODE 2]
indicating that the unit is powered and there is no battery attached.
2. Attach the battery to be charged.
3. The unit will analyze the battery and begin the charging process indicated
by the constant illumination of the STATUS light (indicting a healthy battery)
and the constant illumination of the CHARGE light (indicating the charge
cycle is in process).
4. The battery is fully charged when the CHARGE light is no longer lit and
the STATUS light is constantly illuminated.
The CHARGE light may repeatedly briefly illuminate at the conclusion of the charge
cycle. This is normal and indicates that the charger is in the Pulse-Current float charge.
The battery is fully charged and is ready for use.
