Got any charger recommendations? :)
And yeah, the lithium AA/AAAs were news to me too. I learned about them when I got a headlamp that could either take 3 AAA batteries or a same-sized lithium battery with +/- contacts in the right places. I think the single-cell ones include a buck converter along with the charging circuit, which probably cuts down on the space they can devote to the battery itself.
- bxparks 7y agoYup, it's old but I use this Titanium Smart Fast 8 Bay AA/AAA charger (https://www.amazon.com/gp/product/B0035HCTLS https://www.amazon.com/gp/product/B0035HCTLS). The manual states that it has negative delta-V and timer shutoff. One of the Amazon reviewers mentions a problem with deeply discharged batteries, similar to what I've seen where I need to charge the battery twice. By the way, this situation happens mostly on my motion-activated staircase LED lights which take 4 x AA. That thing is amazing because it works until 3 x AA are essentially dead and only 1 x AA is giving out power. For most of my other devices, the device stops working before the battery voltage becomes that low.
