This I can not recommend. Although the price and shipping fees were reasonable and the item arrived on time, it does NOT work. I own one already and I know how to use it properly. I have attempted to use it to charge multiple batteries and it will NOT charge them at all. The unit is supposed to charge a battery until fully charged, then turn off automatically. It does not do this. When plugging a battery into it, it lights up indicating that it is charging. However, after charging 2 different batteries for over 12 hours each, it neither charged the batteries nor turned off as it is supposed to do. I have no problem exchanging the item if the seller contacts me as I do need a second charger, but I definitely need it sent back. I need instructions from the seller on how to proceed. Until the item is returned and credit paid back or the item is exchanged. I can NOT recommend the item or seller positively.
