I hate this scale, it says low battery and shuts off after just 3 months of sitting in the drawer. It infuriates me that there’s still a lot of energy in the battery, I can use that in remote controls with no issues

If there’s enough battery to say “low battery”, then there’s enough battery to show the measurements!

    This is probably not what you wanna hear, but when the battery gets low, the current gets weaker. If the current gets too weak, the scale becomes more and more inaccurate. Like, wildly so. In other words, the alternative is to lie to you. Badly.

      Agree. For clarity, the circuits that show the low-voltage status are much less hungry for current than the circuits that measure weight. So no, having enough battery to report low voltage does not imply that there is enough to make an accurate weight measurement.

      I’m bummed that when I had a Thinner bathroom scale, I could weigh myself before and after using the bathroom to see how much I expelled. It was consistent and really useful knowing its precision during keto months (lost up to 3lbs a week). Now I have a Taylor scale that will report the same weight over and over if it’s relatively awake and you change less than 5lbs. So, no thanks to scales that lie.

    That’s not really how it works. The components of the scale require a certain amount of current especially if it’s digital in nature. As a battery approaches being drained, it produces less current. Less current can often power an analog device to a lesser degree, like lighting up an indicator light or LCD or even the IR LED light on a remote, just very dimly. But the tolerance of the weighing components is probably much less than the tolerance of the LCD panel or LED bulb. So many devices use an LCD or indicator LED bulb to show that the device isn’t necessarily broken, it just needs new batteries.

    If it’s sitting in a drawer and getting drained, then it’s probably not turned off properly or it may be the type that turns on automatically when it gets pressed down and inside the drawer it’s getting activated. Instead try taking the batteries out of any device that sits around for a long time without use. It will prevent accidental draining and also reduction the likelihood that the batteries will leak after a time. I usually pop the batteries part way out or put them in a small bag that I attach to the device with tape or a twist tie. Just make sure they aren’t touching anything metal and that the poles aren’t touching each other. Batteries will lose charge over time, but with alkaline batteries, that’s usually years, not months. Rechargeables generally take much less time, though.

    I had a scale that kept measuring! It was great! I lost so much weight in the week before the battery finally gave out! Too bad my clothes didn’t get any looser and all that weight came back on when I replaced the battery, but for a short moment in time weight loss became super easy! Turned out there was a reason other scales stopped measuring lol.

    I have the same scale and bought a few rechargable ithium-Ion AAAs and they work line a charm having a constant voltage until empty.

    Only downside is that you don’t get any warning when they are about to run.

    (Something like that: https://www.mediamarkt.de/de/product/_verico-verico-li-ion-akku-loop-energy-aaa-mit-usb-c-buchse-2er-pack-lithium-ionen-akku-109861637.html )

    Edit: nvm, just saw your comment about yours usung a coin cell it seems like there are some deviations between different models of the scale.

    Normal AA or AAA battery, or a CR<something> button? If it is a button cell, try wiping it with alcohol before you insert it. Many modern button cells have a coating that tastes horrible to prevent people (children) from taking them into the mouth. I’ve noticed that on some brands, this coating measurably increases the resistance of the cell, not only reducing the the power it can deliver, but als making it appear “emptier” than they are ofor the measuring circuits. Wiping off the coating with alcohol (90% isopropanol) expanded the cells’ life (in a kitchen scale to boot!) significantly.

      My cheap scale will not work with my freshly recharged amazon basics AAAs. Apparently those do not hold up well enough under load. And of course any set of batteries that does work, discharges over a few months.

      So I just bought a cheap mechanical scale (not from Amazon) and I eyeball it for weights under 50g. Good enough and dead reliable.

        This may or may not help, but a nickel is very close to 5 grams. You may be able to slap something silly together with a bunch of nickels taped together :P

    CR2032 batteries are hit and miss in my experience. Sometimes my car FOB burns through one a month2 and other times they’ll last years.

        In my experience you can feel how good they are by how heavy they weight in your hand.

            Funny that you mention Panasonic, because that’s the brand I noticed it first with.

            The Panasonic cells that come with a device are usually garbage, also the stuff you get on flee markets and cheap packages on the Internet.

            They apparently have cells that hold up and weight noticeably more.

            For the standard sizes like AAA, AA and D cells there’s only Duracell for me. They’re still miles ahead of their competitors imo.

              It’s my first time getting name brand in a while, but it’s possible it’s like OEM tires, where the tires that come with your car don’t have as much tread as a new tire you bought yourself, even of the same model.

                Exactly. They don’t want to provide them at all, but customers would get furious, so they cheap out as much as they can.

    My scale looks similar to this. If I leave it on it goes into sleep mode which still drains power slowly but turn on instantly as soon as there is weight on it. If I hold the power button when I’m done it turns off and makes a beep and then I have no issues turning it back on months later. Still on original batteries after 2 years.

      Nice, which brand/model? I have a scale for making pour-over coffee that has 0.1g precision, but I seriously doubt my scale is actually accurate to 0.1g.

      I have a 0.1 accuracy scale from aliexpress and it works everyday with its soon to be 10 year old coin battery.

      I’ll buy a rechargeable one if ever it goes to scale heaven.

    I believe I have this exact same scale, and I also hate it. My main problem is that those capacitative buttons sometimes refuse to work, and it’s real nice when I’m trying to measure something in grams and it randomly gets stuck in pounds.
