Alesis Fusion affectionately known as "The Beast" I just checked the battery voltage in my non working Fusion 8HD, it's about 12 years old. It started out at 2.88 volts and very slowly creeped up to 3.03 volts. When the voltage drops below 3 volts it is time to replace it. The Fusion uses this battery - Panosonic BR2325 3V Lithium 165mAh Standard Fusion Battery Primary (Non-Rechargeable) BR2325-HGN I am going to order two new batteries for my Fusion 8HD's. I am going to go with the BR2330A/GA which has a higher capacity and and hopefully longer life. Panosonic BR2330A/GA 3V Lithium 255mAh higher capacity Battery Primary (Non-Rechargeable) BR2330A/GA The BR2330 is has the same dimentions as the BR2325 except it is 0.5 mm thicker. I need to find out if 3 volt power needs to be supplied to the main PCB while the battery is being replaced? |

All Alesis products I own Nanosynth, QSR and QS8, and now the 8HD use that idiotic solder-in (BR2325) battery. I noticed it had the solder-in BR2325 back when I first got my 8HD in 2006 and tore it apart to replace the 40GB HDD with the larger 128GB (formatted to 120GB) "just because" I could. Back then I was hoping Alesis had moved on to battery holders like most of my other gear Roland, Digitech, and others. So I knew in about 10 years I'd want to change it out. Last week I just went through and changed all my other gear's batteries and their "RAM" card batteries as well. But because it's a PITA to break out soldering iron, I put off the Alesis stuff as well as two of my MIDI patch bays (JL Cooper MSB Rev 2's use the same solder in battery config). Oh well! I (we) really should change all of them out with batter holders no reason not to, there is room in all that gear to use a holder. If a holder is road rugged enough for Roland boards and modules - it's rugged enough for these boards as well. It was probably just cheaper to NOT use an extra part in the MFG assembly (a battery holder), plus I assume they thought you'd be more inclined to pay for Alesis service center maintenance to change a battery if it was solder in - who knows. In next few weeks I need to find time to tear part my 8HD, QSR, QS8 and Nano (and those two JL Copper MSB Rev 2's) and do a R&R day. I always just backup user memory, R&R battery sans power, and then restore user memory - no biggie. But I guess if you don’t have a PC to save SYSEX to or a second QS*, 8HD, etc. that you can "mirror" sysex to it would be a problem and you'd want to maintain power on while R&R'ing the battery
BTW Jesse I was going to ask you about that LED LCD mod. I bought that $20 LED back lighted display over a year ago now and thought next time I open up my Fusion for whatever reason (probably for this battery change) and before my CCFL lighted LCD goes out I'd remove and replace it with that new LED one. fusioneer.proboards.com/thread/2746/replacement-lcd-display-backlight-fusionDID you ever mention WHERE or how to tap off 3.3 volts from the PSU (old original PSU) and the new modules' pin (I think I keep the specs on that display and it should have pin out but…) - any insight gained by you while doing that mod much appreciated. Since a few boards are no longer needed (when R&R the old with new display) would not one of those boards (closer to the display unit) be a better source of voltage? Truthfully I have NOT run through each and every post on this topic in detail so you may have already posted all this already if so - my apologies Thanks Larry |

Hi Larry, Glad top see you also maxed out the HD on your Fusion. I TOO did this (just because I could  ) and now both my Fusions are 128Gb SSD (formatted to 120Gb - of course) and also 384Kb Ram . . . The battery thing IS a PITA. I guess it keeps the price low AND is ideal for robotic assembly . . . It's a quandary though - seeing as the batteries can last around 10 years - if it makes sense to fit a holder. It's my "tidy mind" that sees it as a "sensible" thing to do IYSWIM  It can bite you in the arse though - I installed a socket on my ageing Yamaha SY85 on it's original 1.10 mobo - all fine a dandy . . . Then I had the opportunity to acquire a 1.20 mobo (which fixed a midi bug in the firmware) I did the transplant - all OK - perfectly functioning SY85, but, you guessed it - the 1.20 mobo had a soldered-in battery  . . . Oh Well . . . Having just got the 6HD, I'm letting the SY85 go, due to space considerations . . . . I'll let Jesse take over re: the display connections. He kindly sourced TWO of those for me some time back - so I'm equipped to to THAT upgrade when the time comes. ATB parametric |

Larry, I was tapping 3.3 v off the power supply connector on the main PCB, but I want to check out a couple things this weekend, let me get back to you This coming Sunday 2-26-2017

That's fine any info before I dig in is appreciated. You'd think I'd dig right in being an ex-tech and hobbyist (USAF aircraft avionics) and still do my own LARGE item repair, mainly tube amps and guitar PUPS, etc. (I'm actually a guitar player NOT a keyboard player), but eyesight is no where close to what it was and FINE work is a lot harder to do now (plus I've gotten fat and LAZY -LOL).
Parametric/Jesse
Yea, I was following that thread on R&R of HDD with SDD - I've thought about it (also just because). But I don't gig, and when I do play, I don't pound on it - so it really doesn't get much in the way of G-force abuse. Furthermore, I keep a copy of entire 8HD HDD on my PC, which then itself gets backed up so double redundant. Lastly, I still have the original HDD so even if the current HDD goes south I got an immediate "bench stock" replacement. I think I just talked myself out of it - :-) LOL

I was thinking about installing a battery holder, but the original lasted 12 years so I will probably just solder a new battery in, but if anyone runs across a compatible solder in battery holder let me know.

Jesse first thanks for info on screen R&R. Second , your first LINK TO A BATTERY is probably incorrect - it has right drawing but wrong ACTUAL "leg"/post config - the positive posts (top) has only one and is Centered not two offset (as needed and properly shown but its wrong pic for that exact battery). When I reference and x-reference in a few places the -1HB is not right, you want a -HGN. I will supply some links with data sheets and you can re-verify (I MIGHT be wrong but.. I've used the -HGN's and they are right) The battery you want (if only going for a direct R&R) is a BR-2325/HGN positive has two "posts") not a -1HB (positive leg only has ONE "post") www.digikey.com/product-detail/en/panasonic-bsg/BR-2325-HGN/P193-ND/31948Like I said I KNOW these are correct because I have used them in before Nano, QSR, QS8 and other Alesis units Spec sheet with DRAWINGS na.industrial.panasonic.com/sites/default/pidsa/files/brconfigseries_datasheets_merged.pdfbest I can tell by ref/x-ref is the 1-HB is an HCN in drawing SORRY for late info - I should have double checked as soon as I saw your post. But I don't visit these (or many forums) very often. Good Luck and thanks again |

Alesis Fusion affectionately known as "The Beast" Larry, this is the right battery, it's showing the under side which is negative, one pin and the top positive is two pins just like in the picture from my Fusion 8HD The BR2330 is only slightly thicker and should provide a little longer battery life. BR2330A/GA Jesse |

yes that one is correct config for that BR2330. but again your very first listing and link for the BR-2325 "Panosonic BR2325 3V Lithium 165mAh Standard Fusion Battery Primary (Non-Rechargeable) " while right PICTURE - the link is to wrong battery "sub type." Your link points to a BR2325-1HB which is actually this one: www.newark.com/panasonic-batteries/br2325-1hb/lithium-battery-3v-coin-cell/dp/22C5028you could make it work with extra solder; or a piece of small gauge wire, or... in any case any of these batteries WILL work just go Rube Goldberg with first one |

Alesis Fusion affectionately known as "The Beast" I think you are right, allied showed the correct picture for the type of BR2325 used in the Fusion, but the wrong battery. BR2325 battery for the FusionGood catch Larry, Thanks I'll change the links here and on the Fusionzone  |

Alesis Fusion affectionately known as "The Beast" Just a reminder our Fusion's are 10 to 13 years old and if you have not replaced the battery in your Fusion you should consider doing this ASAPMine is now 15 years old and hanging in there |

Alesis Fusion affectionately known as "The Beast" A good way to prolong the battery life is to turn the Fusion clock off if you won't be using it for a few months, then when you crank it up again you will need to set the time and date, however my Fusion is a little over 18 years old and I have never turned the clock off. The last time I checked the battery voltage it had dropped a little, but it is still working |
