Hey I'm just saying....when I see on the forums that people willing buy ebay $2 18650 3000mah batteries then leave them on charger all night makes me worried some one may be hurt by using the old charger that came with there energisers. I relise that the CPF users tend to consume info on everything torch, battery, runtime, lumuns, tint, shade of green ... (you get the drift) related, a lot of people dont have this forum to ask the numerous questions (like myself) and at least try and be as safe as they can.
I also have a system in place to monitor all my batteries and wont mix batteries at all. I even carry a USB enloop charger with me and have a seperate enloop for that is dedicated to my single AA battery torches (did the research and they can charge single batteries). I have considered gettinga Pila but cant justify an extra $50 to recharge batteries that I already take good care of. I just think the above senario could catch out a lot.
