I am wondering if there is not an Internet Battery lobby that would have to write lots of pseudo-scientific articles proving that A + B recharge alkaline batteries is impossible and dangerous and what to protect its captive market.
In any case, this universal charger is not much more expensive than conventional models and has been for me a small problem: he failed to charge a 9V alkaline battery type 6F22 but ... hey, let's not be more royalist than the king, since I can reuse batteries that I had stored in the container to swing adhoc and pollute the planet a little more ... and I do not even mention the savings on purchases piles of blister packs. I think, for my high consumption of batteries, a profitability, barely a month!
The conclusion is that non-rechargeable battery charger works incredibly well and can be purchased with confidence!
