Please store these instructions in a safe place, and be sure to pass them on to the new owner if you ever dispose of the charger. In the ULTRA TRIO PLUS 14 you have acquired a mature product with an excellent performance. [. . . ] Cells with a higher cell voltage are discharged at an additional current of around 100 mA (balancing current). However, Ni-MH batteries have a less pronounced voltage drop than Ni-Cd cells, and a practical range has proved to be 5 . If the trigger voltage is set higher, there is a danger of overcharging the battery; if set lower, there is a danger of premature termination. We recommend that you carry out a series of test charges to establish the ideal trigger value for your batteries. These programs are only suitable for charging and discharging LiFePO4 batteries with a voltage of 3. 6 V / cell, and Lithium-Polymer and Lithium-Manganese batteries with a voltage of 3. The outstanding feature of Lithium batteries is their much higher capacity compared to other battery types. However, this important advantage is offset by the need to adopt different handling strategies: they must be charged and discharged using specific methods, otherwise they will be damaged, and can be dangerous. The directions in these instructions must be observed at all times when handling these batteries. Specific information and safety notes will also be found in the battery manufacturer's technical information. The fundamental rule is that Lithium-based batteries may ONLY be charged using voltage special chargers, and the charge program must be set up correctly in terms of final charge voltage and capacity for the battery type in use. Because some types can be charged with upt to 2C or 4C charging current, the charging current and the capacity of the battery must be set seperately. When the battery on charge reaches the specific final voltage which is appropriate to the battery type, the charger automatically reduces the charge current in order to prevent the battery exceeding the final permissible voltage. If the battery manufacturer states a charge current lower than the 1C rate, then the capacity (charge current) must be reduced accordingly. We recommend the use of the balancer connector, which ensures that your Lithium batteries are charged optimally, and therefore increases safety and their useful life. Problems caused by mistreating batteries: It is very dangerous to overcharge Lithium-Ion batteries, as they tend to react by gassing, overheating and even exploding. 2 V / cell (Lithium-Polymer and Lithium-Manganese) is exceeded by more than 1%, the lithium ions in the cell start to change into metallic lithium. This material reacts very violently with the water in the electrolyte, and this can result in the cell exploding. On the other hand it is also important to avoid terminating the charge process before the final charge voltage is reached, since this reduces the effective capacity of the Lithium-Ion cell markedly. Lithium batteries must not be deep-discharged, as this leads to a rapid loss of capacity. This effect is irreversible; it is absolutely vital to avoid discharging the batteries to below 2. Caution: the cell type, cell capacity and cell count set on the charger must always be correct for the battery to be charged; if you make a mistake, the battery could explode and burn!
