Battery life?

[ms33trm]

Sorry if this has been brought up before but I have had a JTV69 from new for about 15 months and the original battery has now died and refuses to take a charge. Inserting it into the charger sees the red light stay on for about 10 seconds then it goes off. Battery tester shows voltage of less than 1 for a few seconds then nothing. I have a 2^nd battery which is working properly in both guitar and charger. I have only charged the battery about 12 times in this period as I have only used the battery power on a few occasions when I have used a guitar amp as I always use the VDI power cable from a Pod X3, HD500 and latterly a Firehawk FX. The failure is a bit disappointing but my reason for posting on the forum is not to have a go at Line 6 as I love the guitar and Firehawk and a dud battery can happen to anyone, just a pity it was outside of guarantee although it is probably not covered anyway. I digress; my question is if you use the JTV exclusively with a DVI power source from a pod etc. should you take the battery out of the guitar or does it make no difference? I might add I do not leave the DVI lead plugged in when not in use and always lower the volume pot to zero when not being played. Average use of the guitar is 15/20 hours per week.

If I'm always using VDI cable with my Firehawk or Helix  - I remove the Tyler Variax internal battery during the gig  - never had a problem. 

 

Also I remove the internal battery when storing the Tyler Variax. 

 

There is a fair amount of "leakage current" in the Variax circuitry ( due to power steering diodes) , which translates into if you have a fully charged battery, and install it in the rear of the Tyler Variax, then put the guitar back into the gig bag for a couple weeks, don't be surprised to find the battery has died when you finally get back into playing. 

 

Also I once had a  Tyler Variax Battery that seemed dead - but I left it in the official Line-6 Tyler Variax AC charger for 24 hours and the Battery finally came back to life and is still working today.

I have a battery that wont revive. Wondering if I should try to jump start it with a little low voltage out of the charger?

 

it either shows 7.4 volts and wont charge or 0 after I let the JTV drain it.

In my experience, these things will either take a charge (in ever diminishing amounts), or they won't.

 

I hate batteries...especially at the insane price of these ones in particular.

If you are not using it you should not leave it in the guitar IMO.  These  batteries do die if they ever discharge too far.  I think the Variax does discharge this battery at a very low rate when you are not using it.  I think it will last a lot longer on the shelf.

Occasionally I'll use the JTV in the studio without the POD where the battery in the only option....but it doesn't take a full charge anymore, no matter how long its in the charger. Most I'll get is 3 lights when I put in in the guitar...thankfully, that's rare anyway. Battery lives in the case 98% of the time. Batteries in general just suck.
