SuperNova 250S Charger
Dear Customer Item No. O-SUNG-RP250S
Thank you for purchasing the highly advanced, low cost, easy-to-use Ripmax Pro-Peak SuperNova charger. To obtain maximum performance from your new charger, please carefully read the following instruction manual.
The SuperNova 250S is an innovative multi-function charger far superior to existing conventional chargers. This unit is especially designed to maximize charge efficiency using SJ’s own unique algorithm. The integral 2 line, 16 character LCD screen displays various information relating to the operating modes and adjustment parameters, as well as key functions such as battery charge state, which shows the percentage of capacity remaining. Furthermore, the SuperNova 250S is very user friendly, even for beginners, thanks to its 10 intelligent selectable ‘battery parameter’ memories. The 10 memories, containing factory pre-set battery parameters, can be re-programmed to store your own standard battery pack parameters so that you can obtain the same precise results whenever you charge.
FEATURES
• Designed to fast charge/discharge 1~25 cell Nickel Cadmium
(NiCd) & Nickel Metal Hydride (Ni-MH) packs, and to charge only 1~6 cell (2~12volt) Lead Acid (Pb) batteries.
the battery being discharged.
• Zero Current Voltage Check prevents incorrect delta peak auto cut-off caused by high connection resistance or high resistance/old/faulty battery packs.
• Uses either 12volt Lead Acid battery or 10~15volt DC power supply input (Not supplied).
•The most outstanding feature of the SuperNova 250S is its 10 intelligent battery memories, numbered 0 to 9.
These enable individual cell or pack parameters to be memorised and stored, i.e. battery type, number of cells, battery capacity, charge current and discharge current.
As a result of this, up to 10 different battery packs can have their individual charge/discharge requirements set.
• Low and over voltage input battery warning function-input voltages outside the range 9.5 to 15.5 volts causes a warning message ‘Input Power’ to be shown on the display, together with an audible warning.
• Automatic initial charge stage checks the condition of the battery being charged. If the battery is not in a condition suitable for charging, the display shows a warning message
‘Output Battery Connector Error’ along with an audible warning.
NOTE: The SuperNova is supplied with the 10 memories already programmed. Unless these programs exactly match your requirements, it will be necessary to modify them to suit the battery packs being charged. How to carry this out is detailed under Setting Battery Parameters.
• In the event of the battery being charged becoming disconnected from the charger the display shows a warning message ‘Output Battery Connector Error’ along with an audible warning.
• To protect both the charger and batteries, the maximum charge and discharge currents are automatically limited.
• When discharging battery packs, the discharge cut off voltage level is set at 0.9 volt per cell to avoid damage to

battery is connected as this may cause a short circuit.
• DO NOT cover charger.
• Avoid short circuits.
• Take great care over battery polarity, and observe the battery manufacturer's recommendations.
• If NiCad/Ni-MH packs are severely overcharged they may become very HOT. For this reason it is always best to place the pack on an insulated heat resistant surface for charging.
• NiCad/Nickel Metal Hydride cells become WARM to the touch when charged. If the pack feels HOT to the touch, disconnect it at once.
• The charger must ONLY be used in completely dry conditions.
• Connect the input leads to the 12v supply first, then connect the battery to be charged.
• DO NOT disassemble the charger.
• NEVER leave the charger unattended whilst charging.
• ALWAYS disconnect the NiCad/Ni-MH /Pb battery when NOT charging, as they may discharge themselves if left connected.
• DO NOT allow the input crocodile clips to touch each other or the case of the charger when the NiCad/Ni-MH/Pb
• DO NOT fast charge batteries immediately after use while they are still warm, allow to cool to ambient temperature before charging.
