Sony MZ-RH1 US-Model 1.090 Battery

Hi Minidisc Forum. I'm a little worried about my MZ-RH1 because suddenly the battery won't charge while in the USB cord (pc connection) or from the wall adapter anymore. Luckily, I had a spare, new battery and tried that...it worked perfectly. However, due to the inconsistency of the battery charging, is it because of the battery or is there a deeper issue with my RH1? FYI: I used the same original battery that came with my RH1 3-4 years ago. I thought Lithium-ion batteries had a life of about 5-10 years. If anybody could provide insight, it would be greatly appreciated. Thanks!

Will it "discharge*? If you leave it alone for a couple of weeks, and swap it back in, you may be amazed.

In future though, the recommendation (I think) is to run it down once per month, and recharge using the wall charger, NOT usb.

Good luck!

3-4 years is about the lifespan of a modern battery. Especially in the RH1, that never charges/discharges it completely and doesn't even see it if it's deeply discharged.

It does seem to discharge, and I did take the precaution of letting the battery drain once per month and re-charging it via the wall adapter. However, today I tried charging it via USB and the battery indicator is gone but after I disconnect and see if it's charging or not, it went up a bar. I guess it's not totally not working but still there's something sketchy...I tried re-charging it via the wall adapter and it won't recharge at all now. Again, the spare new battery I got has no problems and is working as is...Is the LIP-4WM battery (original) considered "dead" or is there some other method I should try?
