In this video I show how to properly replace the battery on an Ensoniq ESQ-1 Digital Wave Synthesizer. Make sure to backup all info before attemping this battery swap as this process will wipe everything as soon as the old battery is removed.
The correct battery for this synth is a 3V Lithium 1200 ma, 2/3A cell and it can be purchased at Digikey at the link below.

Damn. You think they would have just installed a battery compartment on the back or bottom of the unit for easy replacement. Unreal the work you had to go through just to change out a battery. Poorly thought out design, still one of the best synths out there. Good work on your instruction video though. Props.

@revelation1165 Год назад

No way could I have done it without your step by step demonstration. It was very clear thank you very very much. My ESQ 1 has a serial number ending in 44. It's one of the original metal ESQs - I guess that's why it didn't need a metal plate. I believe the new battery I have installed will last 10 years. I hope so because it was still quite a task for a beginner -again thank you, Mike

@SISKworks Год назад

Awesome. I love hearing that.

@sclogse1 2 месяца назад

I also have an all metal ESQ-..Just days after my purchase in San Francisco I got a call from Patrick Gleason (or was it his rep?) saying they wanted to "borrow" the thing. I said no. You may remember Gleason was (is) a big time synthesist.. Only last year did I discover he was a low numbers collector...I replaced my battery in a Berkeley shop way back and soon after the keyboard got parked. It never left my big deal and is covered up..

Good video. General tip - when removing components, snip the legs of the component to avoid stressing the board - especially when removing ICs.

@Brani1974 2 года назад

Great design Ensoniq! There is ONE thing which will need to be replaced at some point, so make sure you need to remove every component there is to get to it!

@bugaljackson494 6 лет назад

THANK you for this! I got my ESQ-1 in like 2012 I believe and needed to swap the battery since. But shops wouldn't take it in for repairs, couldn't find any visual guides except for dudes doing the battery holder replacement, which is NOT recommended afaik. So I may just try to follow this guide and do it myself.

@patsonmusic 3 года назад

Here's a video with Markus Fuller doing just that on his SQ-80 which has similar design. And instead of this expensive special battery he adds a new battery holder for CR2032 batteries which are mainstream, cheaper and available everywhere. And of course they won't last as long, but I think it is a fairly nice update. And with the new battery holder exchanging batteries is so much easier. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-I3LJTsILbOo.html

Super helpful Mike! Thank you! Dumb question but I'm not super handy. Do you a list of tools one would need to complete this job? And do you know the battery information?

@SISKworks 4 года назад

Kirk Bentley There is a link in the description for the battery that I used. For the tools you will need a Philip screwdriver (to open the case), adjustable wrench or socket (for the 1/4” jack nuts), soldering iron and solder wick. I think a good soldering iron and solder wick are the important part. I use a Weller WES51 solder station and the wick I use is just this copper braid that is literally called “solder wick - soldering remover”

Watch this video. The exact steps won’t be the same but the general idea is similar. Open the unit, locate the battery, figure out what you need to disassemble to get to bottom of board that battery is attached to, desolder old battery, solder in new battery, reload memory then enjoy 😉 Also, if you anywhere near Southern California I do offer repair services as well. If interested contact me through my website www.siskworks.com

@@SISKworks it has a floppy disk and hard disks can be used as well. All samples and presets are loaded that way. So I believe that is how everything is stored. That makes me believe that is doesn't but I don't know that definitively. Thanks.

@Johnsormani 5 лет назад

you don't have to take out the main board to change the battery. Just clip the wires and desolder them from the top with a solder sucker

@SISKworks 5 лет назад

John Sormani yes you CAN do it from the top by cheating and clipping the wires like you suggested but that is NOT recommended. You really should just take the time and do it the proper way to ensure you don’t mess up.

Hello thank you so much for posting this it was of major help replacing the battery on my esq 1 (plastic). However I also need to replace screws for the bottom panel that hold the keybed and it's been difficult finding the correct screws, do you know what kind of screws they are by chance? Ik they're phillips but it's hard finding right measurements and if they're coarse or machine thread. Thanks again!

@SISKworks 3 года назад

I can’t remember exactly and that synth wasn’t even mine so I can’t check for you. Check on the inside if it they are connecting to metal or plastic. I think they go through plastic bottom and into the metal of of the key assembly so I would THINK they would be machine but idk.

@StrbMmry 3 года назад

I just got an Ensonic SQ2 from a buddy of mine for free. I've never used a digital keyboard/ synth before, but I have plenty of experience with electronics/ robotics. I just wanted to throw this out here and see if someone could help me figure this out. So, when I jack into the headphones port, I don't get any sound. The display works, but the LEDs above each button don't light up when you press whichever button you want. I tried giving the kayboard a factory reset, but the display didn't show anythinf other than "Button #_" when I did what was necessary to reset the keyboard. I honestly have no clue what to do about it. I assume the LEDs are possibly blown or aren't drawing any power. Bad battery? I dunno.

@p.granger8824 3 года назад

Nope. If it had anything to do with the battery, the Sq2 will display Low Battery on display startup.

@AnVedi7 6 лет назад

Hello Mike! Thanks for your video. I soldered new battery on my Ensoniq KT-88 as a way to delete the problem with display (nothing shows when I turn on keyboard, Grand Piano plays only). It didn't helped. Can you give some thoughts how and what more I can make for the display's working. Thank you!

@SISKworks 6 лет назад

An Vedi Sorry this was the only Ensoniq I've ever worked on and I am far from an expert on this. But no display would not be a battery issue. I believe the battery only effect the memory. First I would inspect all cables and connectors to make sure they are fully seated. Then inspect the power supply to see if any capacitors are expanding or leaking. Power supplies are the most common failure in most electronics. Also just scan all boards to see if anything looks burnt or fried.

@AudiophileTommy 6 лет назад

I have an Ensoniq MR-76 ,Where is the battery in it ?

@SISKworks 6 лет назад

Tommy A. Wood I have no idea. I’ve only ever touched this one Ensoniq ever. Have you opened it up to look? I’m sure it will be obvious if you take a peek.

@bloobeyond 6 лет назад

So wait, this brilliant synth only works with battery? No 9 volt plug?

@SISKworks 6 лет назад

The battery is only used so the synth can remember and load presets. It will not work with just the battery. Also the battery is 3 volts not 9 ;-) Thanks for watching.

@RichardSchletty 5 лет назад

The ESQ-1 operates on 110 volt AC power. The 3 volt battery is only for storage of presets in memory. I just use my synth as an input device (via MIDI connection) for Apple Logic Pro digital instrument tracks. I can do this even with a dead battery in the ESQ-1.

@darwinmcdmusic 4 года назад

Hey Mike, Just pulled my ESQ-1 out of storage and am getting the battery warning. Does this require soldering on a new battery no matter what? Or did you have to do that because the previous owner had soldered the wrong battery on? I don’t suppose its normally a pull the old batter out and put a new one in. Also, when you say back everything up, is that just for sequencer data? Or does that also include the internal (default) sound patches? Thanks!

@SISKworks 4 года назад

darwinmcd music Yes this will definitely require you to solder even if it had the correct battery to start. The backup is to save the internal sounds it has. If you pull that battery out without doing a backup first all sounds will be lost. Also if the battery you currently has completely dies you will also lose all the sounds.

@darwinmcdmusic 4 года назад

Mike Sisk Thanks for the quick reply. I don’t have a way back up the internal sounds. Sequencer data is already gone but was hoping the internal default patches would not be reliant on the battery. Bummer. 😞

@SISKworks 4 года назад

darwinmcd music so this ESQ-1 is my brother in-law’s so I didn’t do the backup part but I pretty sure he backed it up to tape like this video shows but I think you might also be able to back to midi sysex but I don’t know the exact process. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ptUGU9zVhIc.html

Hi is it safe enough to keep the original battery in there ? i own the first metal case esq 1 model with the battery vertically positioned on the bottom left of the mainboard and it reads 0.33v so its definitely dead but there is no corrossion or any other sign of damage, is it safe to keep it there or at any time this thing can explode causing damage to mb ?

@EnochLight 3 года назад

Old batteries will eventually rupture and cause electrolytes to leak all over the motherboard PCB (and cause further damage). It may take a year, or it may take several years. Highly suggest you consider replacing it as some point.

@Pan6888 3 года назад

@@EnochLight Thanks Mike i bought it a few months ago and since this synth is a keeper i will replace it asap, i am familiar with basic soldering but since i bought it second hand and the battery was never replaced i thought that its so many years in there that the battery is tottaly dried out, it reads as far as i remember 0.30 V so needs at least to remove it somehow and why not replacing it with tha CR2032 equivalent if it holds 3V. i have replaced a battery succesfully with a VFX but sold it cause it had the well known keyboard issue, the ESQ 1 doesnt have this problem cause keys arou mount in there with a spring system which makes this a great advantage compared to later models.

@p.granger8824 3 года назад

The 2032 is exactly what I used on a SQ1. They’re inexpensive and fairly reliable. I had some old motherboards laying around so I desoldered the OEM coin holder off an Asus and put it into the SQ1. Soldering in batteries is crazy imho, especially if you’re taking the time to do the work and don’t want to risk anything doing it repeatedly. I’ve seen videos of skilled keyboard repair guys snipping leads and soldering in holders. Their consensus, why screw around with something if it’s unnecessary outside of some neatness which is never seen?

@keithchua5840 5 лет назад

Will you lose the presets patches after changing the battery?

@SISKworks 5 лет назад

Keith Chua Yes. You will lose all presets when that battery is removed. You will need to back everything up before attempting this and then need to restore/reload those saved preset after.
