Worst battery leakage I've ever seen! Casio CT 380

In this episode, I find an old Casio keyboard at an estate sale that has been eaten alive by battery leakage. I spend some time doing a full restoration on it and then a quick demonstration.

[@officermeowmeowfuzzyface4408]

Battery corrosion happens when you have a current and continue to draw life from the battery after it is dead. The zinc outer shell of the battery is eaten by the contents. Don't just use the same type, *TEST EACH ONE* every time you replace all the batteries. 1.5V, 1.5V, 1.5V, 1.3V, don't use the odd one!

[@Jayden-eb2zm]

Thanks for sharing!

[@phantom498]

3 years late but w/o a multimeter there is no way to check the voltage of the battery right? I don’t have a multi meter at the moment.

[@AshesOfEther]

This should be a Duracell ad

[@georgethomas493]

no kidding

[@BillehBobJoe]

George Thomas the issue is the mixed battery types, whichever battery was weaker is guaranteed to lose the corrosion battle, if the duracell wasn't newer than the corroded battery it would be corroded instead

Oh my god, I love your channel!

[@RailRide]

+Larry Bundy Jr Your comment prompted me to check my own Lynx 2, which I had no idea if the batteries were still in it or not, since it had been so long since I last used it Of the six Duracell AA's inside, only one showed any signs of leakage, and it was confined to the metallic portions of the end caps. All the other cells were pristine. The "freshness date" on them? March 2009. And they still had enough charge to boot up the device and play a round of Pinball Jam without keeling over. They had to be almost new the last time I played this particular unit, which could have been in excess of ten years ago.

[@Larry]

RailRide Yup, ALWAYS take the batteries out if you aren't going to use something for a while. Put them in a zip lock bag or something.

Argantonis True, it's just that I have lots electronic devices that I sometimes forget to take the batteries out.

@@lesharkoiste 20x19x18 is already so much, you meant +, not x And also, my calculation is simpler, two-instrument combination is 20x19 divided by 2, because 1+2 is the same as 2+1, and add the solo 20 to that.

I've played a lot on that exact model. The purchase year was 1990 or possibly 1991, so I would agree with the 1989 guess. It was WAY cooler than my own Casios (PT-20 and MT-65) back then. Today, it is the other way around...

And why was the old corroded one replaced with a new one? 4. You can clearly see some yellow stuff on the positive terminal of the battery. Meaning it leaked. -5. Why is the ground cable corroded?- After closer inspection, it wasn't damaged by leaking batteries. If it were to be that way, than the spring should've been corroded too. ----------------------------------------------------- Actual moral of the story: He was either paid by Duracell, or he is a clear sellout.

You should name this video better. I think it's a great demonstration of your skills and how to fix a very common problem with electronics. You would get more views and as a consequence, more happy owners. Do you sell your repaired keyboards? Excellent work!

[@8BitKeys]

What would you call it? I haven't sold any, but I do plan to eventually as I have accumulated too many!

[@bayzano]

Well. Taking a look at your other videos seems that you are above average in this one, wich is great (around 20k views or so). I did a Google Trends search for "battery leakage" and is a term that is increasing in searches since 2012. Adding something more descriptive to what you actually did in the video like "repair" or "cleansing" had not enough volume to show a trend. With that said, you may not get much volume from searched terms but you would have more curious guys to click if you also add "repaired" or "like new" somewhere in the title. I assume that you used the tags section to describe your video. Try adding: diy, electronics repair, battery leakage cleansing, how to and other related terms. If you sign this keyboard, after all the work you put on it, and you certify is the one from this video, it would be interesting to be acquired by someone like me. Even if it is not the best Casio Keyboard ever, you having it repaired is awesome.

[@YeCannyDaeThat]

Not necessarily. Have you seen the title of casey neistats videos? Totally abstract and yet he has managed to make some of the best blogs of all time.

[@bayzano]

Great point! I assume Casey's subscriber base (5M), popularity (1 billion views total) and historical authority (since 2010) allows the KZbin Algorithm to expose his videos to a larger audience. It looks that every time Casey publishes a video it has a lot of views and a lot of engagement, so is a proven success for the algorithm (which gives preference to what works). In this case, I guess if 8-bit Keys works to improve titles and descriptions with more popular keywords, it may increase the exposure to new viewers that may be searching or interested about these themes. I am not saying it's been done wrong, because I love this content and I wish I had as many subscribers and views as 8-bit Keys has, on the contrary, I want more people to be expose to this amazing content! I can't tell this is the right way and the only way to know if it would work is experimenting. Cheers!

[@mitchmatthiesen5845]

@ 8-Bit Keys I think the term you're looking for is sample based keyboard. There's a difference between sampling keyboards and sample based keyboards. Sampling keyboards such as the Casio SK-1 and the Yamaha VSS-30 allow you to record arbitrary samples and play them back via the keyboard keys, whereas sample based keyboards store samples of acoustic instruments in memory,, such as a piano, a flute, or a violin for instance. Not all sampling keyboards are necessarily sample based. The Yamaha VSS-30 is based on FM synthesis. Anyway, with sample based keyboards and synths, some samples are produced by combining wave forms and""/or samples to best represent the instrument its tamber is supposed to resemble. The Vtech Little Smart Super Soundworks is at its heart a sample based synthesizer and you can find an article about it online.

CVS Pharmacy batteries are horrible. Put them in 3 Mag Light Flashlights and all 3 were ruined. Batteries wouldn't come out of the flashlight so they said they had no way of knowing it was their product.

[@olafs20016]

Are they CVS brand or are hey some other brand brought there?

The brass sound is just straight up what they used for the stranger things intro.

[@PizzaHutAsuka]

Well, I don't mean that it's 100% what was used for Stranger Things, but it sounds nearly exact.

That MN234000CSH is NOT a microprocessor, but a mask-programmed ROM in a DIP-40 package. It's model number is MN234000 and the 'CSH' might mean 'CaSio' something, since it is programmed specifically for the Casio keyboard.

Holy Cow To The Third Power! In all seriousness, great video man!

It is unbelievable to see your home and neighbors without a fence. Here in Brazil it is impossible! We are living in our "house arrest". I visited some places in the USA, Ann Arbor and Lansing - Michigan, Knoxville - Tennessee and a beautiful little town, Loma Linda - California, where I did an experiment with high energy protons. USA is incredible! Congrats on your KZbin channel. It's a pleasure to watch every video of you.

[@psirvent8]

Since I'm fixing electronics for my family and other people I think I'm gonna show the part of this video with the battery corrosion to the "special" ones who did bring me devices which had... corroded contacts from leaking batteries to convince them to REMOVE THOSE DAMN BATTERIES ! when not using the device for a long period of time. Thank you for this video. The only "issue" is that I'm french (as the people I sometimes get to work for of course) and few of them actually read english. But I think the images may do their effect though ! ;)

I have this same keyboard! I really love it and it was free. I will say that the little speaker it comes with makes headphones a must. Great video!

[@mrlufus]

You saved the Keyboard's life very well... Good Job Dude!!

[@Cloud_Strife1997]

... I just realized my little cousin's piano toy has mixed batteries. ... Brb while I freak out.

[@twicethemegapower3995]

The main problem with mixed batteries is long term storage, you should remove them when not in use, but mixed batts will cause the brand with stronger current to charge the weaker ones and they leak

@@Xilog Please don't replace the colloquial term "voltage" with the official one which is "tension", it can cause temporary health issues for linguists. Or so is said.

I absolutely enjoyed the short song you made with it. It almost belongs in an episode of MacGyver or in a video game while receiving instructions for your critical mission.
