Most of the devices that I use batteries for are not high drain, not even my flashlights (because LEDs). I would prefer always having a stack of batteries to having to buy more (because they are always in use) and remember which are charged.
My camera, laptop, smartphone, kindle, etc all have their own rechargable battery, so what is left is mostly my Ikea tradlos, kitchen scale and car keys (plus associated stuff that i forget and which therefore can be assumed not to need all that much recharging) which all runs on the super small batteries (2032? 3220? something like that), that I haven't seen as a rechargeable model.
No doubt this will change with kids, but until I have them they won't matter.
- Zak 8y agoLED flashlights can be extremely high-drain depending on the ratio of output to size, but "high-drain" with regard to battery performance may be lower than you think. If 12 hours of constant operation will drain the batteries, low-self-discharge NiMH like white Eneloops or AmazonBasics will outlast any brand of alkaline. Higher self-discharge (loss of charge when not in use) offers more capacity, and only extremely low-drain devices will last marginally longer with alkaline. There are Li-ion button cells such as 2032, but their voltage range is higher than the disposables and their capacity is quite low. Their applications are fairly niche.
