What causes this and how do I clean it? It's all inside my wireless mouse and a fresh battery didn't work.
>>2864039It's potassium carbonate and completely harmless. Just wash your hands.>What causes thisMany things, but mainly letting them run completely empty and keeping them around.
>>2864044I'm more concerned with cleaning inside the mouse. Doesn't appear to be on the contacts so I'm not sure what's causing sudden death. Just alcohol and a cotton swab?
>>2864045Honestly, just blowing air would probably be enough. Not sure how it reacts with alcohol, but it's probably fine.
It's a bad connection. Wiggle the battery around and it turns on but then off when it de-wiggles.Any suggestions? I cleaned it out pretty well with water and a cotton swab.
To avoid making another thread: What type of disposable battery is best?The battery the mouse came with was an off brand that I haven't heard of, but it was noticeably heavier than the energizer that I replaced it with and lasted way longer (and didn't leak)
>>2864062Might have to do some tiny sanding if the terminals are still dirty.>>2864065It’s probably all in your head. I’m sure you can google actual mAh ratings from somebody testing them. Duracells and energizers have always been fine for me. And I hate Harbor Freight, but their blue Thunderbolt batteries actually seem to be right about the same capacity. They’re similar in price to Duracells, but they have sales sometimes to get an 18pk for $5-$6 and it’s worth it. I’ve had Panasonic cells come with tons of devices that seem to hold upEnergizer lithium batteries are really good but expensive.Be a champ and get some Energizer Industrial packs fron Amazon.
>>2864067>>2864065Kirkland might be the choice!There’s different graphs too. A lot of the Alkaline batteries that are close will probably move around on the top rankings depending on the load. Some might to better with faster discharge while others have a higher capacity on a low drain device.
>>2864065> What type of disposable battery is best?Energizer ultimate lithium are objectively the best but you get like 20% better performance for twice the price of Duracell lithium. Lithium > NiMH > alkaline
>>2864071>others have a higher capacity on a low drain deviceWireless mouse very low drain>>2864073Lithium batteries are rechargeable. I've seen batteries with a USB recharging port. Is that what you mean?
>>2864039That's corrosion
>>2864075Nah those Energizer Lithium aren’t rechargeable. Or they’re not supposed to be. But they last awhile. It’s like $20 for a 4pk of AAs though, decide if changing batteries half as much is worth the price.
>>2864065Generally, the heavier the battery, the higher the capacity. Some cheap ones are literally only filled with half a battery.AFAIK, all batteries can leak, but at least alkaline batteries like yours don't leak any toxic material. For some things, voltage stability or temperature rating is important, but not for a mouse. Just take whatever, seriously. The batteries will last months if not years.
>>2864075>Lithium batteries are rechargeableNo. https://en.wikipedia.org/wiki/Lithium_metal_battery
>>2864093Stick a power supply on there and see. I’ve seen videos of people recharging disposable AAs and stuff in a crackhead moment… not sure how well that goes
>>2864107You first

>>2864065I’ve never had a nimh leak.On the other hand, virtually every alkaline, of all kinds, has leaked.I always assumed it was yet another planned obsolescence deal struck by mfrs.I has some alkalines destroy a very expensive lab thermometer (because they killed it, and leaked all over the pcb). I considered suing the battery manufacturer, but i managed to get it fixed by taking it to a local electronics repair guy, who laughed and warned me away from alkalines.Now the batteries are in a separate box connected by wires so they won’t leak all over the fucking CPU.
Vinegar on a cotton swab is very effective for cleaning this white battery shit off electrical contacts and battery compartments.This happens when you leave batteries in a device for literally years, or in a very damaging environment (humid). The battery eventually leaks. To solve this problem, remove batteries from devices before they are stored for a long time.
>>2864039>how do I clean it?Contact cleaner and a plastic brush e.g. Tooth brushhttps://www.wd40.com/products/contact-cleaner/Use in a ventilated space, it's fine to wash off your hands quickly but I wouldn't want to inhale that shit
>>2864233Just had a discussion about this on /o/, started about MAF cleaner.I wouldn’t waste the money on the contact cleaner for that application. It’s basically some aerosol fast drying wannabe alcohol thing. Use the isopropyl alcohol and let it dry and it will be the same results. That contact cleaner doesn’t do anything special when it comes to breaking down exploded batteries beyond what alcohol does.I do like the contact cleaner, but it’s expensive so I only use it in places where I need to blast that tiny straw in and a q-tip with alcohol doesn’t work as well.
Assume all battery juice is toxic. Clean with isopropyl and q-tips because alcohol is wetter than water do not inhale it could be toxic. The corrosion could have messed up a connection inside evaluate the value of your time. Personally I'd buy a new mouse, but this is diy be careful with the fragile plastic clips not easily fixed when broken. Would not consider a mouse as user serviceable but most of the optic stuff works on relative position so bumping it is not a problem. Once open it does not get easier.Vaseline is a decent material for cheap solder I think the lard helps conduct the heat.
>>2864337>decent materialdecent additive material. Applied to the board not the soldering tip.
>>2864339Thanks for clarifying that…But I’m not slathering the PCB with fucking lard from my huge 45 gallon barrel of lard I keep next to my lazyboy and just dip into every now and then with my hand to use as a snack while watching mash re-runs.
>>2864039use nicad or nimh batteries and never have to worry about this again.
>>2864073>Energizer ultimate lithiumI put one of these in my pager and it lasted almost a year, compared to a standard alkaline which lasts only a month or two.
>>2864375I got some of those Blink cameras, each one runs off 2x Energizer Lithium AAs. The camera instructions specifically say not to use alkaline AAs or anything besides lithium. They advertised “Up to 2 years battery life!” with the cameras and I figured that was bullshit and maybe I would get 6-9mos out of each set with real world use, maybe a year on the camera that sees the least activity. I’ll be goddamned it’s been right around 2 years or a little more and I haven’t had to change the batteries yet even though each camera has definitely taken hundreds and hundreds of videos, lots of them in the dark where the battery is powering the IR light as well and even the camera that is set off like 100 times on windy days because of shadows from trees and a flag.
>>2864181The battery is less than a month old. Maybe the dollar store isn't the best place to get batteries. Also my wall clock is dying already.
>>2864039Alkaline batteries do that if they lose too much power without being used. They gradually lose power while idle so it will happen if you leave them unattended for too long but it will happen much faster if they're left unattended at high temperatures.As to why it's happening, these batteries produce a gas when they discharge on their own and if too much of that gas builds up inside of them the pressure bursts the battery. That crud is formed by contents that leaked out of the battery after it burst.>how do I clean it?Just however. Lick it if you want. It's potash. There is stuff in that battery I wouldn't eat, but that white powder is safe. You can buy potash at the store and cock with it. It's a leavening agent (similar to baking soda).As to the "right" way to clean it... I would probably use vinegar. Potash is a mild base and vinegar is a mild acid so if you mix them they will turn into dirty water. Dry the dirty water up and you're good.
>>2864720>The battery is less than a month old.They expiration date in your picture is March 2018.>>2864153https://www.edn.com/teardown-is-the-mighty-charger-a-good-investment/
>>2864726That's just a google pic.
>>2864720Wtf so you live in a swamp? What's the indoor humidity?
>>2865339My guess is that they were already expired when I bought them.
>>2864724I generally see this with batteries that have been run dead and then left to sit. Expiration in 2018 doesn't help much either.If you use equipment frequently, you will notice when the batteries run dead. If you let equipment sit, take the batteries out. Store in plastic bag or pill bottle with the gear. Let the batteries rot. At least the device will be OK.
>>2864071I’m autistic so I bought 50 eneloop batteries, a smart charger for them. Then I calculated it and I was paying more per battery use than just buying Duracell so I bought a $20,000 solar panel system and an add on battery for that to make my power consumption cheaper So for about $21,000 you can half your dollar per battery/dollar per charge setup As well as lower your costs charging your car, lower your per minute use of the gaming pc and lower your per charge cost of your power tools I can’t run 3 phase off my panels though so full price to run my mill
>>2865574>I want to power my $50 wireless mouse>Pay 20k for solar panels
>>2864039your mouse has 2 batteries? Why?Also hijacking your thread to say that I'm tired of changing the batteries in my mouse so I want to buy a rechargeable one. Which one should I get?
>>2865627It's not my pic I got it off google. Also you should get the logitech superlight 2
>>2865629if your mouse has batteries then how do you know what rechargeable mouse I should get?
>>2865653I researched both and decided I didn't need to have a $200 mouse and also I didn't trust the optical switches. I should have gotten the $200 mouse.Picrel is what I ended up buying. No double clicks (yet)
>>2865662>I didn't trust rhe optical switchesWhy not? Every no -optical Logitech mouse I've ever bought has started doubleclicking within a year and a half because they're cheap fucking jews
I went to pick wild lithium and found this inch sized shroom growing on it, and I said to myself how common is this thing?
I still have a sample by the way looks like a lithium clam
>>2864039I found the threadI knew they were alive
>>2864044> potassium carbonateIs that stuff useful for anything, should i collect it from dead batteries or something? Or maybe useful for electrolysis or plating projects?
>>2866589I'm sure if you needed some you could find it and not have to extract it from bad batteries.
