drowner77 Posted July 18, 2024 Share Posted July 18, 2024 Hi, I have a JTV59. It was working perfectly yesterday, however today not so good. I use two batteries for my live show. One charges while I uses the other. Today, both batteries would only stay charged inside the guitar for almost exactly the same time, about 20 minutes. They are both charged fully according to the charger and the battery gauge on the guitar shows them to be full, as well. However, they go from full to zero in 20 mins. I believe the problem is the guitar, as I cannot believe both batteries are kaput. Can anyone help? Quote Link to comment Share on other sites More sharing options...
psarkissian Posted July 18, 2024 Share Posted July 18, 2024 1-What are the last four digits on the battery part numbers? Could be it's time for newer more current ones. 2-Could be an issue with the battery box. 3-Some other thing deep inside pulling down current. More than likely #1. Contact the Line 6 authorized service in your area, they will have more experience with these. https://line6.com/find/service_center/ Quote Link to comment Share on other sites More sharing options...
drowner77 Posted July 18, 2024 Author Share Posted July 18, 2024 I don't have the batteries to hand, but it was working great last night and today it's giving me palpitations. Could it really be the batteries? Also, the map you linked isn't showing any repair centres near Greece... Quote Link to comment Share on other sites More sharing options...

I find it very hard to believe that both batteries just decided to have the same catastrophic failure simultaneously... stuff like that rarely happens, if ever. A rechargeable battery's performance/longevity declines gradually... it doesn't just suddenly fall off the cliff from one day to the next, and certainly not two of them announcing "We're dead now" at the exact same moment. Nope, something else is going on. What it is, I have no idea... Quote Link to comment Share on other sites More sharing options...
jerseyboy Posted July 19, 2024 Share Posted July 19, 2024 Cold/cool lipoly battery temperatures can drastically reduce C rate. You’re working in room temperatures or higher, yes? As the good man advised bring those last 4 digits of both batteries back here. Short of Line6 service maybe a friendly RC model enthusiast can measure the battery pack IR and C rate to help provide some battery health guidance? 2s1p 18650 cell configuration. If the packs are good and it’s an over current situation something should be getting pretty warm inside? Because in order to drain roughly 2Ah in 30 minutes would require nearly 4A load or roughly 25-30 Watts for system voltage. Nearing the heat output of a small soldering iron.

psarkissian Posted July 19, 2024 Share Posted July 19, 2024 98-034-0009 is the current part number for batteries. Being what an early serial number it is, could be one or combination of what I listed. Triodo Service S.N.C. Via Caduti Di Nassiriya N .47 Bari, BA-70124 080/5013427 info@triodo.it ... would be the closest to you. Quote Link to comment Share on other sites More sharing options...
drowner77 Posted July 19, 2024 Author Share Posted July 19, 2024 My roadie did suggest that it might be heat related, as it is extremely hot here in Greece at the moment.. I will test tomorrow, my next gig, to see what transpires and report... Btw, total bad move discontinuing the Variax.. 1 Quote Link to comment Share on other sites More sharing options...
psarkissian Posted July 19, 2024 Share Posted July 19, 2024 Heat,... it can have some effect. Remember, you have 11 year old gear, and probably hasn't been serviced in some time. So more than likely your batteries are as old as well, as may be getting a bit spent by now. Even Li-Ion batteries need replacing at some point. 1 Quote Link to comment Share on other sites More sharing options...
jerseyboy Posted July 19, 2024 Share Posted July 19, 2024 Extreme heat does accelerate degrading chemical reactions. Once the chemistry is damaged and dendrites take over it’s damaged forever. High IR means cells can no longer deliver the current they used to deliver. Although cells might still be able to provide seemingly good capacity at lower discharge rates - the resulting saggy voltage of high IR will confuse LVC (low voltage cutoff) circuitry. As the good man says 11 years is definitely beyond the calendar life expectancy of even the best quality lipoly cells. Even if not cycled deeply or often. Much agreement about discontinuing the Variax. Bad move. Quote Link to comment Share on other sites More sharing options...

Thank heavens the JTV's keep functioning as a reg guitar - got me thru a few shows while I figured it out. Turns out there are thermal safeties in those batteries, and the ambient plus sun beating on the guitar was enough to trip them even showing a good charge. I finally started keeping spares in a cooler, could typically get a set out of one before swapping out. Fortunately those kinds of gigs were an exception. If this is happening on indoor gigs, haven't a clue - can't imagine indoor temps in those ranges. Quote Link to comment Share on other sites More sharing options...
drowner77 Posted July 20, 2024 Author Share Posted July 20, 2024 Both batteries are 0009.. I set up in the afternoon and put a battery in the guitar. I am back now and it's about 8 hours later and the battery is still full.. It's looking positive.. I will report after my show tonight.

drowner77 Posted July 20, 2024 Author Share Posted July 20, 2024 Gentlemen, I am so happy to report that the Variax worked flawlessly tonight. I am anxious to see if it works tomorrow night, as well before I get too pleased.. If all is good then only thing I can put the battery failures down to was the heat, which was near 40dgrees on Thursday.. Anyway, if all goes well tomorrow, I will be very relieved. I will report again. But this has given me a wake up call to get a spare Variax... Again, thank you all for your thoughtful replies. Quote Link to comment Share on other sites More sharing options...
jerseyboy Posted July 21, 2024 Share Posted July 21, 2024 Good to hear drowner77. I wholeheartedly agree a spare or two is probably best. My work is mission critical and with Line6 going Dodo on these amazing guitars there’s some strength in numbers. And of course our good man in Calabasas. I work 2qty JTV59’s (custom Bigsby’s) and JTV69. Sometimes ‘use batteries but majority of the time Helix via VDI. Safe travels my friend… Quote Link to comment Share on other sites More sharing options...
psarkissian Posted July 22, 2024 Share Posted July 22, 2024 Both batteries are -0009's,... Maybe the battery box. Have the 59 checked out at a Line 6 authorized service center. And if they want to pick my brain further, they can contact me thru our service tech channel. Thank you jerseyboy. 1 Quote Link to comment Share on other sites More sharing options...

Boys, I am chuffed once again. 3rd gig on a row and not a single problem. I can only conclude the issue was heat related. However, When my season ends I am taking.your advice and sending my JTV to the service center in the U.K.. Jersey boy, Rock on, my friend. My wife thinks I'm full of crap in needing a spare, but she can divorce.me if she wishes, I need another. P.S, I think Yamaha and Line 6 are missing a serious trick by not Variaxing the Revstar. 1 Quote Link to comment Share on other sites More sharing options...
jerseyboy Posted July 27, 2024 Share Posted July 27, 2024 Wives will get over it. Hahaha I wanted to share (gloat) ‘grabbed a 3rd JTV59. The last 2 used ones 2019, 2017, respectively. Gotta say both these newer 59’s are somewhat nicer build than my original 2013. Both slightly lighter weight and the fit, finish, everything just seems nicer. Not by a huge margin but noticeable to me. And I’m sure the newer builds have most, if not all, electronic components updated to the latest improvements. Notably the “blue” switch on tone knob seemed to be a problem on my 2013. Solved myself but it was something to deal with. I’m sharing this in case yer wife comes around and shopping for #2. Highly recommend 2017-newer. Quote Link to comment Share on other sites More sharing options...
