First, we appreciate the affordable price of this kit Duracell, a reference mark. We can thank Duracell offer quality without asking exorbitant prices. Everyone knows the little rabbit, guaranteeing quality and longevity. This complete kit allows charging its rechargeable batteries in just 4 hours! Load LEDs to know the charge or is to not let the charger heat up unnecessarily, which would damage your kit. Once finished loading, you will find that neither the charger nor the battery is excessively hot. It is important to properly charge its rechargeable batteries on first use. The charger is compact compared to other commercial chargers and can charge two AAA batteries and two AA batteries (which are included in the kit) in 4 hours or a little more. The batteries charge by two (2 or 2 AAA AA) but I do not necessarily think it poses real problems, quite the contrary. The shape charger (rectangle) allows plug it into a wall outlet that but I think it's a guarantee of security. Your kit will be more responsible (longer life) and the charge will be done quietly, without danger. It is lightweight and easy to use. The instructions are clear and French. The charger is guaranteed for 5 years and dsiposent duralock battery technology allowing them to not unload when they are not inutilées. Please note, AA batteries are slightly bent backward once in place. So you have to and do not force them correctly so that the load is done well. After trying a number of magazines, I highly recommend this kit!
