User manual TRONIC KH 967 UNIVERSAL BATTERY CHARGER WITH TIMER FUNCTION

[. . . ] Intended use This appliance is intended for charging Ni-Cd / Ni-MH rechargeable batteries of Size Micro AAA, Mignon AA, Baby C, Mono D and 9V battery packs, for personal and household purposes. It is not intended for charging commercial type batteries (even rechargeable types), or lithium-ion batteries, or for use in commercial or industrial applications. Risk of injury!Never load commercially available non-chargeable batteries into the appliance ­ these can overheat and explode. Safety instructions! · Never leave the appliance to charge unsupervised. [. . . ] Otherwise the charging process cannot start. b) Test the batteries first!If you do not know how charged or discharged your batteries are, you can test them as follows: Move the switch to the far left, to the position with the "Test" symbol. The test indicator light at the symbol is lit brightly if the battery is sufficiently charged. If the test indicator light is lit only faintly or not at all, then the battery is almost completely discharged or flat. If you would like to test the other batteries as well, they must be inserted one after the other into this slot. The test function is not available for 9V single block batteries! Ni-Cd batteries should only be recharged when they are almost completely discharged. Otherwise, a "memory effect" is created, where the batteries reduce their capacity to the lower level at which they are actually used. Ni-MH are not susceptible to the "memory effect". 5 c) Discharge Ni-Cd batteries first Ni-Cd batteries that are not fully discharged should be discharged first, to avoid the possibility of "memory effects". If you have inserted up to 4 Ni-Cd batteries, move the switch to the far right, to the position with the "Discharge" symbol. Allow the Ni-Cd batteries to discharge until the test indicator light is barely lit, meanwhile testing the batteries a few times. For this, push the switch all the way to the left, into the position with the symbol , , Test". Important: Do not allow Ni-Cd batteries to become completely discharged, as this may ruin them. Therefore, do not allow the batteries to discharge until the test indicator light goes off completely. The discharge function in the four charging shafts is available for 1. 2 V batteries only ­ not for 9V single block batteries. d) Charging batteries If you have inserted the batteries the right way up, as described at paragraph a) . . . move the switch to the center, to the position with the "Charge" symbol, and . . . If all batteries have been placed correctly, the charge indicator LED lights up at each charging slot. If a charge indicator LED is not lit, even though the battery has been correctly inserted, then the battery is faulty. This will provide sufficient protection against flying battery parts in the event of an explosion due to overheating. 6 e) Keep to the charging time!The best protection against battery overheating is not to exceed the proper charging time. If you wish to calculate the time exactly, please refer to the technical data for information about the charging current required. [. . . ] Taking out batteries When charging is complete and you wish to take out the batteries, . . . · · · first disconnect the power plug from the power socket, wait until the batteries have cooled. Storage If you are not going to use the appliance for a long period, disconnect the plug from the power socket and remove all batteries from the charging slots. Caution: If you do not take out the batteries, deposits can accumulate over time at the terminals, depending on the quality of the battery. [. . . ]
