All the new contact sensors seem to be that large now, including Philips' and Aqara's new ones. They do indeed use larger batteries and they claim several years of use. But man they are so bulky I don't see myself using them. Total eyesores.
- andylynch 3y agoI really like this change and suspect the reason why is part of their motivation; they button cells used in the common smaller ones are non-rechargeable and this is really quite wasteful given how popular and good AA/AAA Rechargeables are
- moogly 3y agoAre they good really? Like half of my AAA devices don't even work on 1.2V. I've dabbled in USB-C rechargeable Li- Ion AA/AAA, but they're quite expensive and the charge lasts a short time. They're mostly useful in remotes and things like that, kind of like NiMH rechargeables. Meanwhile nonrechargeable batteries get cheaper and cheaper so I just buy them in bulk now. Call me selfish, I guess.
- andylynch 3y agoThe USB-C ones trade on capacity and different ones have different self-discharge rates. Some manufacturers specify Panasonic Eneloop batteries. Some other brands’ are made by the same company and are very similar (including IKEA)
- sangnoir 3y agoYou can purchase rechargeable coin-cell batteries. Device manufactures tend not to care about batteries except for the crappy one they ship in the box - if they bother to do so.
