After the 1989 Loma Prieta earthquake, we lost power, so I grabbed my RCA Pocket Power Pack and plugged it into my DC powered 9 inch B&W TV. The only station on the air was channel 7, KGO, an ABC affiliate in San Francisco. We live in San Jose. The first image was that of the Bay Bridge with the upper deck collapsed onto the lower deck and a couple of cars had driven over the edge. Thanks to that set up, I was able to see that the earthquake was a serious one. I still have that power pack somewhere in my garage.

Ni-Cad cells are VERY robust. From my days of RC car racing, one of the very few things that would kill a cell was if it ever got hot enough to vent. Even then, it would work for awhile at a reduced capacity. I had a 6-cell racing pack that was accidentally overcharged (peak charger missed the voltage peak) and got so hot that the shrink wrap REALLY shrunk and came off. I put new wrap on the cells and it was ready for more racing. I still have a reflex charger that can greatly reduce (if not totally eliminate) the dreaded "memory" effect. During the charging cycle the reflex charger will introduce BRIEF discharge pulses at a fairly high current. After a few reflex charging cycles, the cell/battery will regain most of its charge capacity.

I still have my Tekin reflex charger and a couple of battery bugs from the early 90s. Sanyo cells were some of the best back then.

A while ago I managed to buy a NEC ProSpeed SX/20 laptop from 1989 in still brand new condition, the box never had been opened. The laptop was dead due to an insane amount of dead capacitors, but after enormous amount of googling around to learn the basics of how caps and electronics work, I managed to source new caps and replace all of them in the laptop and in the psu. And the machine works just fine now, it's one of my most valued possession (the whole project took me months doing it in my spare time). It came with a 12V 2.8Ah Ni-Cd battery, and I fully expected it to be dead. But it works, as soon as I plugged it in the first time, it started charging. And not only works, after about 5 cycles of charge-discharge it has recovered virtually all of its original capacity (started from around 1600 mAh, and steadily has been gaining more capacity after each charge, and now it's at around 2700 mAh). I am absolutely amazed that a battery that was made in 1989 would not only work, but after some use it would gain back all of its original capacity. Basically it's in 100% health after 34 years of storage. To verify the condition of the battery, and the capacity I use a SkyRC B6 charger. I understand why we use Li-ion batteries nowadays (much higher energy density amongst other advantages), but I hate the fact that they degrade no matter what, even if just sitting unused. As others have said it, after about a decade they will have significantly less capacity, no matter how careful you are using them or storing them.

[@themaritimegirl]

That is super rad. If I found one of those I would use it with a USB adapter whenever I needed a USB power bank, just because it looks so cool. I can imagine someone back in the day using one to power their transportable cell phone by tucking it in the transceiver compartment.

[@michaelathens953]

It would be cool just for the retro factor, but not super practical. For $20 or sometimes less a modern lithium USB power bank has about 3 times the capacity (10,000MaH) around 1/3 the size.

@@michaelathens953 as they said, it looks cool. I'm actually looking to build a USB floppy. And no, I don't mean a floppy drive with USB, but an actually floppy with USB that has either a thumbdrive or a microsd in it. It has no practical purpose, but it would be neat to bring your floppy around.

Nice! These huge batteries were mostly for use in the old days of VHS camcorders. I had a bigger one. It also used the cigarette lighter plugs. I used it as a spare battery to power my camcorder and also power a camcorder halogen light, it was a way bigger than the one you demonstrated at around 5 pounds. Man, back in 89' when I was 15, I wanted a camcorder and bought one. It was expensive as all heck at a bit over $1,000

[@ZippletTech]

Absolutely crazy. Nowadays you could get the same capacity from a pair of 18650s in a fraction of the size, but modern lithium chemistry is very fragile. I have a similar experience with NiMH cells; I have some 2006 Eneloops that still work pretty much the same as when they were new. Thank you for sharing :)

[@boardernut]

a pair of 18650 is only 7.4 volts, so nope.

[@ZippletTech]

@@boardernut Look at watt hours not voltage - I was talking about capacity/energy density. 3.7 volts * 3.6 amp hours = 13.32 watt hours. 2 of them would be 26.64 watt hours. Roughly the same capacity as the power bank here (12 * 2.2 = 26.4 watt hours). For voltage you'd need to use a circuit to step up, OR you could use more cells and have a greater capacity in watt hours. I'd probably go for more cells (maybe 3 18650s) if I were building a 12V pack.

[@ZippletTech]

@@chucku00 You would be surprised, there are modern high capacity cells from samsung that hold 13-18 watt hours of capacity. Draining 18 watts continuously from them would put them on edge however and you wouldn't get many cycles from them!

[@oleksandrshulha7451]

I've built a power pack(12.6v 3.2amp) out of 20+ year old 18650 from old laptop. It is working completely fine, so i cannot say that liion is that fragile. I even got batteries that has 0 volts when i first got them and after deep charge with small current they are working fine in flashlights.

[@PileOfEmptyTapes]

If you were looking for something more rugged, you'd probably be going for LiFePO4 instead of regular LiIon these days. Energy density is somewhat lower in comparison, but still far beyond NiCd.

[@paulstubbs7678]

Properly done Ni-cad's can last a long time. I came across a power pack for a potable VCR (porta-pak) that was likewise 'ancient' it used SLA cells and still worked - I was amazed, although with repeated use is soon died, but the fact it had any life after all that time, stored in a cupboard with no charging, was amazing. Yikes, where on earth did you get that laptop & TV, they need to go in for the largest bezel award.

[@harrison00xXx]

NiCd batteries LOVE to stay at 0V/discharged (and they have high self discharge rate), thats why they last as long. Using NiCd reduce their lifespan noticable, especially when often being charged.

[@martinda7446]

there are not many ideal conditions for NiCd to care about, NiCd is very robust and even LIKE (!!!) to stay discharged, on top they have a high self discharge rate which make them last so long. NiCd are more or less impossible to destroy/degrade.

[@michaelcross4112]

The power pack looks like it was a well made but probably cheap solution, just a battery bank with a socket and indicators. was probably intended for guys with expensive and heavy camera equipment who might run out in the field but to whom a car battery would be overkill. You didn't have internet shopping so there was only Retail, Phone or Mail order and you had to know where to look to find a supplier. That meant a much higher barrier to entry so if you wanted something niche this RCA would not be competing with as many hobbled together counterfeit batteries just on the basis that available was statistically negligible except in a few cities where there was a big enough grey market. These days you can type in a model number for the thing you want components for and select prices low to high. Thus one warehouse can have customers in multiple countries with zero advertising budget

[@nickwallette6201]

Yeaahh... that's a bit of rose-tinted glasses. It's a battery, in a plastic box, with a socket, and a very simple indicator circuit. There's more going on under the hood of a cheap 2022-era battery bank from a no-name knock-off source. And like was said above ^^ if people were willing to pay for quality, there would be quality products on the market.

[@noakeswalker]

I'd never seen a stand alone NiCd pack designed as a power bank before. Thanks for showing this. From your laptop test, it looks like that power bank has about half its capacity left, which isn't bad after all those years. I believe NiCd cells are still used in some emergency ceiling lights, (I believe they are excluded from the cadmium regulations) because they can be left continuously charging at very low level with no ill effects, and the charging circuit can be extremely simple and therefore will still be working in 10 years' time. (try that with a Li ion charger :-o ) (ps looks like the power bank doesn't have any kind of replaceable fuse or current trip, unless it's automatic)

[@DjResR]

I salvaged two 1990's era emergency lights, one had working NiCd battery because the transformer PCB connection failed and other had the battery completely dead even after 48h charge test (dead batteries in these lights are quite common). Emergency lights do use NiCd batteries still, although it is slowly started to switched to LiFePO4._

The real benefit of NiCd chemistry is the fact that they dont degrade when being empty, unlike NiMh cells which die or at least take damage when too deep discharged. I have still some NiCd packs around, also 10y+ old and they are literally at 0V and still accept a charge (even if its just for 1-2 weeks before they have drained themself...) Also there are some techniques to "refresh"/remove the memory process to increase the effective capacity and decrease the internal resistance a bit. NiCd and NiFe/Fe batteries are the best in my opinion (in terms of longevity). Especially the Iron batteries are a beast (Tiger Tanks from WWII in the mud have 100%, in fact even more than 100% capacity left after being for over 50 years in the mud.

Turns out this hasn't happened in 20 years but the damn batteries are somehow still OK, while any modern ones will leak like there's no tomorrow after a year.

The memory effect degraded the capacity if you didn't discharge it fully. But if you would just do a discharge charge sequence after a few uses, it didn't matter that much. The problem was made bigger than it actually was. It didn't actually completely fail if you didn't discharge it. You couls easily only discharge it partially several times, just give it a cycle or 2 with full discharge after that.

To answer your question about "what went wrong" I can say lithium batteries are a symptom of the direction technology has been moving in the last few decades. Everything is designed to perform great and give a good experience for the years it's going to be used and not necessarily worrying about what happens in 10 or even 5 years. This might seem malicious but consumers in general don't use stuff that long, so things are geared towards giving the best performance for the majority at the peril of the few who hold on to things. With the environmental concerns this trend may change, in the last year or so some phone manufacturers have settings for limiting charge percentage allowing people to have the choice to sacrifice some capacity for a longer overall lifespan.

[@MultipleObjectSelector]

NiCad cells have also fallen out of use due to environmental concerns. If companies would offer battery recycling and if people would use it *maybe* it would work, but cadmium is not a pleasant metal. Even when you have recycling chains that appear to work, as we do with Lead Acid cells, they are still highly problematic: recycling facilities are constantly embroiled in controversy for poor emissions control, raise environmental lead levels, and are usually chased into the poorest neighborhoods by cities because of it. It's a mess.

I found out this year that solar garden lights still use NiCad cells AAA & AA, I guess they are not outlawed in Canada, and this was from a major grocery chain :o

[@rager-69]

Now we know how you celebrated New Year's Eve - testing an old Ni-Cad battery. Beats me watching KZbin.

[@redmonster4993]

You have very cool old stuff man nice

[@LeftyPem]

Humidifier/dehumidifier quote was beautiful. I like to put wax in my humidifier. Makes my room all shiny.

[@MissFoxification]

There's a reason we still use NiCd in some devices, they have been modernised but they still offer the same benefits, just with less of the disadvantages. Most electronic toothbrushes and some high discharge devices have them. It would be nice to see a modern version of that created with new NiCd's, put it through it's paces and compare it to an equivalent ah LiPo and Li-ion pack.

It's good to end on a Cliff hanger ;)

[@JonnyInfinite]

Oh dear

[@Noname_2014]

you have some good radio reception there 🙃

[@ElectronicNoobBlog]

I very like it - big shame it's not serviceable - in that topic on my channel I got emergency light (20years) and it also get almost full capacity with quality NiCd. I remember those power banks - they were used mostly by news agencies to power halogen light while doing interview or something like that. Cameraman plug lamp that was ended by cigarette plug for example Unomat VL100 (very common here in Germany). Thanks

I wish I had one of those power packs back then. They seemed very durable and long lasting. By the way, WINS on 92.3 sounds so good on that Crosley. Have a Happy New Year.

[@LakeNipissing]

Ahh.... I thought WINS is 1010 AM in NYC, and I was very impressed by the audio quality of AM on the Crosley.

[@tvradio1972]

@@LakeNipissing WINS is on both frequencies. It added 92.3 in late October. Even then, I was able to tell the difference between the AM & FM.

[@2ndPyleOfVinyl]

What is the music at 9:38? It played in the background of When Radio Was as Greg Bell introduced the show and hawked Radio Spirits CD sets.

[@vwestlife]

It is a track called "Hiroshima" from the BackTraxx Music Library.

[@dylanlindsay1993]

AWESOME! Best powerbank ever!👍

[@Jon4270]

Wow, look at those operating temperature ranges... 1:42 You could use the thing at -35C! Good for Canada...

[@Gr8thxAlot]

Wow, that thing is a beast! I had no idea this existed, and I'm guessing this cost a pretty penny in 1987. I was saving up for an NES then!

[@Taskforce1]

PROFESSIONAL POCKET POWER PACK PROGRAM - thank you

[@senilyDeluxe]

The original batteries in my 1987 (or 88?) Toshiba T1100+ still worked in 2015, giving 6 hours of runtime. Unfortunately I put the laptop in storage and they self-discharged and now one of the cells is bad. They haven't even started leaking yet! I also have three 12V D-Cell powerbanks intended for emergency light fixtures, they're made in '95 and '96 and these also still work fine. But then again the batteries in the Compucorp MicroScientist (portable programmable calculator, pretty much the precursor to the Laptop, ca. 1973) have leaked badly. The machine still worked though. Plasma Display FTW! But no (or broken) key debounce makes the machine pretty much unusable.

[@ThejasonJaw5442]

Very cool power bank

[@brianleeper5737]

Ambico made a version similar to that one from the 80s. That one had the lighter socket on a coiled pigtail cable.

Simple answer to "why does this thing last so long when modern batteries can't last more than a few years": your RCA pack sat unused in optimal conditions for at least a decade or two. If it actually saw regular use, or the extreme abuse modern batteries take, it wouldn't have lasted half as long as a modern battery. In fact, if you continue using it, you'll likely find it go dead in a few weeks of attempted regular use (try using it with a car USB adapter! Or a 45w USB-PD adapter to charge your laptop if so daring). Problem is, lithium batteries in phones are horribly abused - their controller is programmed to send them to 4.3 volts (beyond max capacity) to call that "100%", and people often charge them on their bedside table every night - plugged in all night, camped at 100%, bursting at the seams. That's not good for them. iOS has made some improvements with "adaptive charging" to try to keep the battery at 80% until it thinks you'll want it, but leaves some to be desired (e.g. if you have an irregular charging schedule, it'll never lock on a pattern, and always charges to 100% anyway). Meanwhile, lithium EV batteries like Tesla are designed for longevity - they inform the user of good charging habits, they charge/discharge relatively slowly (compared to a phone) in everyday use, and there are plenty of >10 year old Teslas still on the road with their original batteries. They've only gotten (much) better since then. tl;dr: it ain't about the chemistry, but the design goals of their creators. Phones are designed for "max power that lasts the warranty period", but with a little intelligent usage, you can make a phone battery last forever as well!

[@Kennephone]

Nicd batteries are a very underrated technology, if well maintained they can last alot longer than lithium, at least the flooded ones can, although lifepo4 has largely replaced them in stationary use due to the capacity and charge cycles.

[@airspeedmph]

Ending in style with Cliff Richard :)

[@HerecomestheCalavera]

This video reminded me that I actually have one of these, in the box in what seems like unused condition. I had to dig it out to see if it worked. The news is not good. I had it in a pole barn in a plastic tote with a lid but it seems the batteries have leaked or something. The box was partially ate up and there was "crystals" on the top. It has the cig plug on the top and that door was jammed shut. I managed to pry it open but the cig socket was all crystalized. Damnit! It is my own fault obviously for storing it improperly but I really wanted to try it out!
