Where Can I Get Rechargeable Button Batteries?

I hate buying single-use batteries, I insist on rechargeable. However I need button batteries for some remotes, and I have a Nintendo Game and Watch that uses Sr44/357 button cells. I'm interested if I can get these in a rechargeable form. Thanks!

  • No such a animal as rechargeable button batteries.

    Unfortunately I've looked on the Internet and couldn't find any that meet your requirements. However if you insist you can recharge the non rechargeable ones manually using a 1.5V 1mA constant current power supply. You can build this circuit yourself using an old USB cable, prototype board, some opamps, resistors, a zener diode, and a transistor. Make sure you charge them in a plastic container as they might explode or leak when overcharged or charged too quickly, as non rechargeable batteries are not designed to be recharged.

  • ebay probably place to get most button batteries (as it gonna have highest availablility)

    Can also try locally (reject shop, coles, woolworths, bunnings, kmart etc.)

    • They aren't rechargeable

      • ah you mean rechargables,

        i dont think they exists in rechargable form factor, you need a device that uses AA,AAA, or AAAA, or the lithium ion 186** factor. You wont find any rechargable button batteries, you just need new device.

        • unfortunately Nintendo doesn't make the Game and Watch anymore, so I can't get a newer one.

  • I don't think there is a rechargeable battery technology that outputs 1.5V.

      There are 1.5V rechargeable batteries. D cells, AAs, AAAs, 9V. They start with a lithium ion cell, then fit a tiny circuit board to the top that regulates the output down to 1.5V. In fact a constant 1.5V from when its fully recharged to when it can't supply 1.5V. But they don't come in button cell sizes as far as I know.

      Look up Tpower, Kratax, Xtar, Pallus, and others.

  • Time to buy a voltage regulator and a small lithium battery like you'd find in small RC stuff.

      You don't have to do it yourself. You can buy ones in all sorts of standard sizes with the regulator built into the top of the battery. But not in button cell sizes.

      • Even better!

    How could you even justify it at the rate they run down?

    What did RS Supply say when you contacted their very responsive support team?

    • Why assume I contacted support?

      • +1

        I didn't.

        • yes you did, your second question implied the assumption.

    Why didn't you also ask where you can get the chargers for such batteries?

  • +2

    Search for a battery eliminator. It's a device that fits where the battery goes then plugs into the wall. They make them for button batteries now.

    • Damn, cheaper to buy battries lol

      • You'd get a lifetime supply for the cost of one of these. Plus it would be rather inconvenient to use on a remote control.

    I got one from eBay. Search for LIR2032 instead of CR2032. USB-C charger for them is less than $5. Not sure about the specific ones you mention, but there are definitely rechargeable button batteries.

    • Thanks. Idk enough about batteries to know whether they will fit

      • A google search would have given you an answer in less time than it took to write that reply. The numbers relate to the thickness and width, so if the numbers are the same, the size is the same.

        • Google have obviously started charging or maybe they have even leased the faculty out to Ozb.

      CR2032s are 3V.

      BR2032s are 2.8V and have a longer shelf life. They are a good choice on things like motherboards where the current drain is so small that the battery is going to reach the end of its life before its used all its capacity.

      LiR2032s are rechargeable, but are 3.9V. And they only have 1/5th the capacity of either CR2032s or BR2032s.

      You can replace a CR2032 with a BR2032, but because of the higher voltage there is some risk associated with replacing either with an LiR2032. Plus it'll go flat a lot faster.

    They exist, but only as 1.2v - which may or may not be sufficient for your particular device.

    Ebay would have similar products if that is your marketplace of choice.
