S1 Pro battery draining when not in use

Warning!

I remember reading a post on here a while back where someone had send theirs back to Bose for repair in the original box, but Bose returned it after repair in a generic cardboard box! 

I will be bubble wrapping mine and sending in a regular box as I'd like to keep my original box!

That happened with me. I sent one of my S1 Pro units in for repair in the original box and it was returned in a plain cardboard box. When I called to see if there was any way to get an original box, I was told no. Since I like to keep my original boxes, I will not include them when I ship mine in for repair.

I keep my S1s plugged into A/C at all times except when transporting them and using them on battery at gigs.  I use them on A/C for practice in my studio almost every day.

Last time I ran them on battery I got three hours and still had battery left.

They're almost 2 years old - semi-early in their battery life.

I'm hoping that whatever defect is causing this problem for others won't bite me here in the middle of the Pacific Ocean...?

The issue does not affect battery life either in use or, apparently due to extra charge/discharge cycles. It only occurs when the S1 is left charged, disconnected from AC and switched off. My replacement (which is now back for repair) took 8 or 9 days to fall below 90% but then another 4 or 5 to lose another 30% charge.

Your charging regime and usage means you will never know if your S1's have the issue (only 10% of owners are reporting an issue but I suspect many, like you, will never discover if their S1 has the problem).

If you continue to use them as you are doing you will be absolutely fine.

Hello ST,

It's good to know that Bose is now repairing the S1 Pro units. Do you think they will get a deluge of S1 Pro units shipped in right away? I'm wondering if I should wait a while before requesting that mine be repaired. Do you think that would be the best way to go?

Thanks,

Michael

Hi, djharryg and DavidE2,

I'm sorry for the confusion.

As soon as I saw your posts this morning, I called our support team.

DavidE2, I see they have already called you back. 

djharryg, please expect to hear from the team (check your email if they haven't called you). Or you can call them back.

Thanks for your patience.

Thanks ST!!  Glad I posted here as I didn't think new batteries would fix the issue unless there was some design change to stop the discharge.  Mine are on their way to Indiana for repair.  I hope this one takes!

A couple more points here:  Thanks Chris M for pointing out about shipping original vs a pack box.  You are absolutely correct -- a Bose agent confirmed this for me. 

Also, they confirmed that the solution to the drainage problem is both a hardware part replacement and a software upgrade.  They said, operating correctly, the batteries should hold a charge for two weeks or longer.  Neither of mine have ever done that so I'm glad I'm getting them fixed.

If they consider two weeks enough it is not a fix, the batteries should retain their charge for several months, a Li-Ion battery system self discharges at 2-3% a month so worst case it should still be at 60%+ after a whole year! I hope this is another case of of you rep getting the wrong info

You're probably right Sam Spoons. I probably misunderstood what they said. After all, I wouldn't know a Lithium battery from a Lithuanian nunnery.

I'm just glad to get it fixed so I don't have to worry about recharging the battery every time I gig.  I probably still will -- but in case I forget or don't have the time, it's good to know I'll have a bit more breathing room than just a few days before it goes dead.

If you're concerned, please find a way to leave one of your units off and not connected to AC power for a week or two. If you see a significant drop in the battery charge please contact Bose Support at (877) 335-2673 Monday-Friday: 9:00 AM - 9:00 PM ET

If you mean Hawaii - Bose will cover inbound/outbound shipping (by air of course) on repairs. Your turnaround times should be similar to customers in the continental USA. There's no penalty for living in paradise.
