    Fucking everything.

    - 80s

    But especially maybe the Game Boy. Or ghetto blasters.

    Edit: Walkman is a better answer.

    I think modding older stuff to use rechargeable batteries is not too difficult. I think the harder thing is replacing the nonstandard charging ports with usb-c.

    I’d love my 3ds to just have a usb-c charging ports I’m considering doing the mod myself.

    My “Pow-Pow-Power Wheels” quad. Would also swap out those bald ass plastic wheels for some rubber.

    Everything that was destroyed by leaking alkaline cells or stripping the battery door screws. LR44-powered toys were the worst.

    It’s good that we don’t use mercury in button cells anymore, but it was exactly mercury that inhibited the off-gassing reaction that eventually leads to leakage.

    Are batteries that much different? I was born in the early 60s, and the batteries my toys used seemed like the same AAA, AA, C, and D batteries we use mostly today. I think the key difference is that a lot of things take a lot less energy than they used to.

      Quite. Unfortunately, most devices that use modern batteries have the battery sealed inside with an onboard charging system, such that when the battery wears out, the device becomes e-waste. There are many standard, or semistandard sizes of cylindrical lithium-ion cells, and devices could be designed for field-replaceable versions, but the only product category where it’s common is high-performance flashlights.

      Even in common consumer form factors, there have been improvements. Here’s a test of one of the best alkaline AAs. Note how the capacity drops as the load increases - by a factor of about six at 3 Amps. Contrast the Eneloop NiMH rechargeable, which has less capacity under light load, but barely loses any at 3 Amps and can handle 10 Amps while retaining most of its capacity.

      The best Li-ions in a form factor similar to AA, called 14500 have even better performance with over 5 Watt-hours of energy, but devices have to be designed for them since the voltage is much higher; putting one in most devices designed for AA will result in damage, if not fire.

        An important thing to keep in mind is that most cylindrical lithium batteries don’t have protection circuitry since they expect the device itself to have it, so if the battery shorts out while outside the device, that’s a really big problem. Same with many RC/drone batteries. I guess manufacturers could embed the protection circuit in one of the terminals but that’s expensive so surprise surprise no one does it.

        Rectangular batteries used in older phones and laptops do have built in protection, but there’s also no real standard sizes and shapes. The closest thing might be the Fairphone or Framework Laptop batteries, at least those companies probably wouldn’t care if someone else started making third party batteries of the same form factor until it becomes a de facto standard. Kind of like how everyone cloned IBM’s PC until it became the standard.

          Battery OEMs don’t do it, but adding a protection circuit to the end is extremely common in the flashlight industry. Ideally, the springs in the battery compartment provide some flexibility about battery length so both bare and protected cells work.

      I grew up in the 90s and I remember how many things took D cell and AA. What got me thinking about this was cordless drills. D cell drills were pretty worthless, but now with today’s batteries, they are just as good as corded. Shit I was at Lowes the other day and you can get a riding lawn mower that is battery powered. So yea today’s electronics are much more efficient, but batteries last longer, can be recharged, and provide substantially more power.

        Yeah, good point. I can’t think of anything I had as a kid that would be drastically improved with modern batteries, but for sure cordless power tools are a big change. I have a cordless electric chainsaw - that wouldn’t have been feasible in the 70s.

    Modern batteries = sealed inside the device and not replaceable, so you have to throw the device away when the battery craps out? No thanks.

      You, in particular know that’s not a requirement for using modern batteries, but a user-hostile decision companies make.

    Literally anything. Even the things I still have that use AA and AAA batteries (of which the newest things are my VR controllers which is so stupid…), I have rechargeable lithium ion AAs and AAAs for so I don’t have to constantly buy batteries.

    As a kid, tho, I loved 9volts because they had the best connectors. I could take a little battery powered motor apart, glue it to some legos and use it to make machines that moved or did stuff. I almost killed myself once wondering what would happen if I took the cord from a busted fan, wired it to the 9volt battery motor and the plugged the cord into the wall outlet.

    It blew up the motor and started a fire. 🤣

      It’s the best connector because you can lick it

    Sega GameGear. That thing had a better screen than any portable gaming device would for another 20+ years, but it would eat 6 AA batteries in less than an hour. There were rechargable battery packs you could get for it but they were heavy as shit and didn’t last noticeably longer, you could play it with the battery pack plugged into the charger but then you’re not actually mobile at all so you might as well play the same games on the Genesis.

      The car 12v socket adapter was awesome though!

      Do you remember how hot the big wall brick would get?

        The car adapter did kick ass, but I never got to use it because looking at anything other than the road while in a moving vehicle would instantly make me nauseous. I do vaguely remember it getting very hot, alarmingly so in retrospect, but I didn’t know shit about exploding batteries at 5 years old so I never worried about it.
