User manual GRAUPNER ULTRAMAT 8

[. . . ] Rechargeable batteries generally - and LithiumPolymer cells in particular - are sensitive and easily damaged. It is therefore essential to supervise the whole of the charge process. warnings and safety notes · This product isn`t designed for use by children under the age of 14, it isn`t a toy! The case slots serve to cool the charger, and must not be covered or enclosed; set up the charger with space round it, so that cooling air can circulate unhindered. [. . . ] The method of charging these batteries is different to the one employed with Ni-Cd or Ni-MH batteries, and is based on what is known as a constant current / constant voltage process. Example: with a battery capacity of, say, 1500 mAh the corresponding 1 C charge rate is 1500 mA, or 1. Once the battery reaches the final charge voltage appropriate to the specific battery type, the charger automatically reduces the charge current in order to prevent the final charge voltage being exceeded. NiMH-/NiCd- cells When set to the Ni-Cd / Ni-MH charge program, the ULTRAMAT 8 can charge packs consisting of one to eight cells with a nominal voltage of 1. The automatic charge termination circuit (battery full detection) works on the proven Delta Peak principle (also known as the Delta-V process), which is already in use in millions of chargers. This process analyses the voltage peak of the charge curve, which indicates with great accuracy when the maximum charge capacity is reached. When the charge process is started the battery voltage initially rises continuously, but as the pack approaches full capacity it begins to heat up. Higher voltages often lead to overcharging of the battery, whereas a lower voltage tends to result in premature termination of the charge process. We recommend that you check the information supplied by your battery manufacturer, then carry out a series of test-charges to establish the optimum value for your battery. If the setting is correct, the battery will be slightly warm to the touch (30 - 45°C) directly after the charge process. The current select switch is used to set the approved charge current for the battery you wish to charge. NiCd / NiMH batteries which are capable of delivering high discharge currents can usually be recharged at a charge rate of 1 C (1 C charge current = capacity charge current. Example: with a battery capacity of, say, 1500 mAh the corresponding 1 C charge rate is 1500 mA, or 1. Liability Exclusion As manufacturers, we at GRAUPNER are not in a position to ensure that you observe the correct methods of operation when installing, using and maintaining this charger. For this reason we are obliged to deny all liability for loss, damage or costs which are incurred due to the incompetent or incorrect use and operation of our products, or which are connected with such operation in any way. Components and accessories As manufacturer of this charger, the company of GRAUPNER GmbH & Co. KG recommends the use of associated components and accessory products which have been checked and approved by GRAUPNER for their suitability, proper function and safety. In such cases GRAUPNER accepts responsibility for these products on your behalf. We are unable to accept liability for parts or accessories made by other manufacturers, which are not expressly approved by GRAUPNER, as we are not in a position to assess every individual non-Graupner item to decide whether it represents a safety risk or not.
