The charger is suitable for charging the following types of battery: NiMH or NiCd packs with a capacity of 0, 6 - 2, 5Ah. They are mechanically robust, can be used in any attitude and are not damaged by vibration. You can usually tell the number of cells and capacity of a pack by its designation: the number before the slash (/) or (-) indicates the number of cells, and allows you to calculate the pack's voltage (single cell = 1. Charging batteries During the charging process a particular quantity of energy is fed into the battery, which can be calculated by multiplying charge current by charge time. The maximum permissible charge current varies according to the type of cells in the pack; the figure can be found in the data sheets supplied by the battery manufacturer. The standard (slow) charge current should only be exceeded with batteries which are marked expressly as rapid-charge types. You must calculate the charge time required and terminate the charge process manually when that period has elapsed. Polarity of charge cables The diagrams below show the polarity of the two charge leads attached to the TWIN CHARGER. Please ensure that the transmitter charge socket and the other batteries you intend to charge are polarised correctly. Caution: the transmitter charge lead is designed to suit Graupner/JR radio control systems. The polarity may well be different with other makes of radio control system. The red and green LED 1 should now flash; this indicates that the charger is ready for use.
