Product to flee! I'm not even sure, given the performance, be it a good brand product. In short, received discharged, I put these batteries connected 9:00 before reinstalling my Maglite. Lighting weakling for two hours and a half before total lights! Super.
For those who would still try it, you will already be surprised that these batteries weigh even a third of the weight of a normal battery .... What arouse suspicions confirmed with use.
