Those exact batteries are famous for leaking and destroying vintage mac computers. Wouldn't leave them in your Fluke for years on end.
Not just leaking but actually exploding.
But realistically, we’re talking about once these batteries are 15+ years old. They did not leak during the service life of the computers, nor for several years beyond.
@@coredditNonsense. They do not explode.
Yes, Lithium Thionyl Chloride batteries were often used in computers (3,6V 1/2 AA) , like many older Apple Macintosh computers with PPC (68X00 and G3/G4 till around ~2005). They do leak (over time i.e. 20 years or so) and then totally destroy those machines, and it's a good idea to remove those batteries before storing those old computers in your electronics graveyard aka cellar.
It's the Thionyl Countdown! Nice moldymeter.
lol, you win the comments
@@_BangDroid_ that was completely punintended - and I could Keri on just like this for months! :)
Runs of the sniff of an oily rag. That’s a good one.
Your pronunciation of Li-SOCl2 was spot on. Sincerely, a chemist.
gamma scout geiger counters run continously, with display on and counting (cant turn them off) and some even got USB built in for data export on a single AA lithium cells for up to 12 years. thats over 100k hours
See if you can make a Clarendon Dry Pile battery (part of the Oxford Electric Bell) for it so that even your grandchildren won't need to change it.
You what would be really cool, a multimeter that ran off solar power, so my thought is it could e powered by the lights in the lab, every time you come into the lab and switch on the light the multimeter come on, then when you leave and switch off the lights it goes off.
I'll have to check the square area available on the top case.
This sounds like a stoner idea if I've ever heard one.
What? Next we'll have solar powered calculators😁👍🇦🇺
I seem to remember there was a nuclear battery in a mailbag episode a while ago. It's probably not going to have enough power to run the meter continuously, but if combined with a supercap and an auto power-off feature, could it work?
@@helgew9008 Those only prudced uW of power...
I've got one of those geiger coutners I think I bought way back in in the mid 2000's or so. It's only guaranteed a 10 year battery life (you can't turn it off) and it's still actually working off the original battery (probably close to 20 years now). It does need to be changed (and you can either send it back for replacement or do it yourself) as the battery cannot supply enough current anymore for some operations, but I'm curious how long it'll last. It does use a TI MSP430 microcontroller, but it does have a high voltage inverter to run the tube.
You could always put a solar panel on top with that low-power drain. 2 or 3 cells and it will last FOREVER!
34000 hours is long enough for around three Duracell PP3 leaks on a Fluke 8060A.
I've got the front end of the Fluke 37 and still works a treat, I need the rest of the case to make it whole again.
You just need one of those fancy NDB chips in there😂
In that large compartment you could add an auto power off board aswell.
Energizer Ultimate Lithium have similar energy density and self discharge, and you can buy them at Coles. They only come in AA and AAA, but you probably have holders in your parts drawer. 20 of them ought to give you a decade @ ~3V2. I think LTC batteries can outdo them in very low current and very high temperature applications, but they contain relatively nasty chemicals and are harder to source. Also, the cheap no-name LTC batteries have been known to explode. And the nice SAFT ones are very expensive. Actually, Energizer Lithium is expensive in Australia as well - they're like half the price overseas.
Yes, I'd have to find them on special. Cheapest IU can find is 16 x EBL for $45
I just call them Saft batteries. Used to be the only game in town for the old Shearwater Predator dive computers with OLED displays if you need decent battery life. They eat batteries. Good thing the newer models are LCD and are battery misers. You can even power one with a carbon-zinc battery for a weekend of diving.
I'd put a solar panel on the top to pickup ambient light to increase the run time....
Thanks for the video.
Put in 4 cells and put in a count down time set for 3 years and at that time you recharge the batteries and reset the timer.
What is the power curve on Lithium Iron Phospate, they are much more stable and will not go up in flames.
I have a 37 at my work. I replaced the single 9V battery a year or two ago. My other electricians leave this thing on constantly and still no low battery indicator. Imagine some small solar cells to maintain the alkaline battery. It would live forever!
would be neat to have something like this, grab a LORA module or an ESP32 and a dac, have it display subscribers count in 1k/V
but that added few mA per poll will increase, granted you only need to do it once per day and the hibernate state (timers only) of an ESP32 is 2.5uA with an external crystal, and a DAC probably takes f all when holding
What happened to that old battery leaking video project? Ever get one to leak Dave?
looks like theres enough space to put a whole lot of tritium battery, i wonder how long it will run with those
datasheet states the are worth only up to 250 mA cont. that's like 14 Ohm load compared to their 50 ohm max advertised discharge curve.
it is going to be garbage..
I have a casino calculator from 1985 that still runs from its original Casio AA batteries.
just add a tiny solar cell, just for ambient light, and it may keep it running even more time...
So it's a distant cousin of the Nokia 3310?
"Found my old phone in a drawer...
Believe it or not, it was on! ... and it even had 2 bars left on the battery indicator" 😂
I think the battery is tested by loading it a very short period at the start, and looking at the voltage drop (delta V) to determine the battery condition.
Yes this chemistry needs to be activated by loading it which removes a passivation layer so current flows. If the current drain isn't high enough, the passivation layer reforms and the battery shuts down again.
34,000 Hour's is only 3.88 years, hardly the rest of it's life.
3.8 years of CONTINUOUS operation, Dave. Come on Mate. Change that to 8hr/day operation and you have 11.4 years. What, only 6hr/day? 15.2 years. I think I wouldn't complain about 3.8 continuous.
The whole point is to leave it on forever.
@@EEVblog2 I understand. Maybe you can get one of those little nuclear batteries. Oops, maybe not. 😉
I got tire of the display contact issues with my Fluke 37 and it went in the burn barrel earlier this year, or I would try this.
