Charger don't charge sometimes

  1. I have a multiplus 1600. Lithium bat.

Sometimes the batteries don't take charge, it just says float on the multi control panel.

Often it starts with that everything is fine and the bats take charge, after 5-10h there is no charging any more. I try to turn the charger off and on but it won't help.

Any clues?

When I switched the on off charger button on the multiplus the charging started again. Is it something wrong with multi control?

Winston batteries? Have you programmed the multi to charge lithium batteries?
