Did the training program my part high-capacity batteries, which were hardly by frequent reloading still able to deliver power, made again to persistent energy suppliers. The falls mainly on the use in consumer, show the weak voltage indicator lamp. Of course, the so-called. Conditioning in older battery somewhat longer (up to 3 days), whereas required in almost new Eneloops lasts only a few hours. If you have several engaged simultaneously he shows at the end of the process (permanent unloading and loading to no increase in capacity more about fairs is) in each charging slot an energy index, ie index 1 is replaced by the battery with the most capacity recording, the next example, 0.98 etc . Since then you have a real overview of the states of charge and may also specify thereupon effective battery groups or individual aussortiern. Furthermore, the part has a selective charging bay choice means you can, for example, in a bay just reloading and in the other conditioning or unloading. Fact is, the AV4m makes your current storage more effectively and protects them. The only disadvantage: because of the compact design only 4 charging bays 100% buy recommendation.
