As the article states, NiMH has gotten a lot better, and I now use that nearly everywhere instead of alkaline.

It's nice not having to shop for batteries as often. I plugged in a charger behind the TV and batteries in a drawer under the TV. With the price point for Eneloop and Duracell batteries, you break even once you use a rechargeable for the fourth time.

Part of the reason I have it in the first place is that the Roku 4's abysmal remote control goes through a set of batteries once every three months or so.

Rumor is the Ikea batteries are rebranded Eneloop I have good luck with them.

This website says that the IKEA brands are equivalent to the Eneloop Pro and Lite, but not the regular white ones:

Seems like at least the AA size, model LADDA 2450mAh. You can check they're made in Japan. Not sure about the 1900 mAh, or the AAA size model, it might be a different brand.

All 3 are Eneloops, just not the same lines (the 2450's are pros). Also their Tjugo charger is one of those chargers that slowly pulse-charges each cell individually and checks the delta, it's a very overengineered and conservative charger design that won't roast the AAA's and AA's from them. Decent video of teardown of it, though the guy wasn't aware of this style of pulsed-charging and why it's done: https://www.youtube.com/watch?v=gG2clNRFz2k

I have a lot of those white ones, and they work great for years now. They're a steal.

I've switched back to NiMH too recently. The ISDT chargers are great - independent charging, and the option to cycle to restore capacity.

Anyone know who makes the Costco Kirkland brand AAs?

Producer likely to change depending on who does them cheapest at the time.

And sometimes varies by region.

Duracell. The Costco CEO mentioned it in some interview a few years ago and they tend to leak as well.

Thank you.
