I splurged on some Ikea Ladda Batteries and was happy that both AAA and AA are Made In Japan which may indicate Eneloop Manufacturing. I was going to order them from Amazon but I've been hearing stories about counterfeits and the price has been going through the roof on them lately. The Laddas are 2450 mAh compared to Eneloop Pro's 2550 mAh but they're 2.5x less expensive. I think the last time I bought Ladda AAAs, they were made in China so this is a welcome addition but they were very low on stock. In case you like watching YouTube while doing dishes like I do, Project Farm tests everything including batteries, he's done several on rechargeable batteries but check out his other tests if you like tools.
Just a word of caution, I mixed two LADDA's and one eneloop in a cheap little flashlight and it started smoking almost immediately. They were different mAh if that is a reason.
Smoking?? As in pre-ignition type smoking or burning and smoking? Can't imagine that much resistance being caused by such a small difference in maH. You sure the connectors in the torch aren't corroded?
A problem I have had in a magnifier light was due to the outer plastic of a NiMH wearing off so the outside of the battery case was shorting to a terminal strip running underneath it. That caused one of the batteries to heat up. On Alkalines and NiMH the entire outer case is at positive potential so shouldn't connect to anything that isn't that batteries +. A bit of insulation tape over the terminal solved that problem. One criticism of Eneloops is that they are right at the top end of the specified size for an AA battery so are more likely to rub against terminals etc.
The flashlight has a three-battery cartridge holder, put the batteries in the holder then slide that in the flashlight. The plastic holder started melting within 30 seconds and it was hot..hot..hot....I set it down and walked into another room and smelled burning plastic, luckily!
