Maybe I'm not up to speed on the latest developments, but I currently have two laptops whose batteries have essentially been reduced to short duration UPS's.
I should be more pro-active, but I forget, or I worry that I'll discharge right before I need to be charged up. And one sits on a spare table, doing its thing all by itself, much of the time.
They tend to stay plugged in and on overnight. It would be nice if, e.g. once a week or so -- whatever's best for the battery at hand -- the power system could run a discharge /recharge cycle "in the middle of the night" or similar.
In my experience, batteries still have memories (that shrink over time and with lack of cycling), and from what I read periodic cycling is the solution.
If Bunnie can find an acceptable fuel cell option, of course I'm all for that. ;-)
P.S. I think I do at least partway understand what you're saying, that being that rechargeable batteries have a limited number of cycles and tend to loss capacity with increasing cycle count.
However, in my case, it appears to be a lack of cycling that is catching up with me well before the above does.
- jakeonthemove 14y agoThat's very weird: my laptops stay plugged and on 24/7 for months at a time, and the batteries still last around 2.5 hours. These are 4 year old Li-Ion batteries I'm talking about (they used to last 3 hours when they were new).
- Too 14y agoSame experience here, i kept my laptop in a socket almost every day for 2 years only bringing it out maybe once a month. The battery was as good as new until i forgot it completely uncharged for 2 weeks when it overnight reduced its 2h capability into more like 2 minutes.
- jakeonthemove 14y agoOh yeah, that kills them pretty fast. I've had the same experience with my backup cellphone and mp3 player, had to buy new batteries.
- pasbesoin 14y agoHmm. Then maybe I'm ascribing my problem to the wrong behavior. I wonder whether I inadvertently left my problem children discharged for too long, at some point. I've gotten reliable service out of my mobile phones, but laptop Li ion batteries continue to feel (for lack of a more consistent and rational/analytical approach, on my part) like black magic, to me.
