Laptop battery dying :(


Vastly intelligent whale-like being from the stars
My laptop battery is dying - logged onto Ubuntu today, and it tells me it's at 34% capacity, and that it may be old or damaged. My laptop is almost a year and a half old, so I'm leaning towards damaged rather then old (although, the laptop was a rather cheap one, $700 AUD or something).

The battery is definitely dying, though - I've noticed the lifetime has dropped considerably compared to when I first purchased the laptop - hardly an hour.

My two questions:

1). Should I buy a new battery? What should I be looking for in a battery?

2). How can I take better care of my battery? Most of the time, I leave my laptop plugged into the charger. I occasionally use it without a charger (maybe ~1 hour every day), but most of the time when I use it, its plugged in (~2-3 hours a day). I leave the laptop plugged in when I'm not using it.

@#2 well there's your problem. Don't keep your laptop plugged in all the time when you're using it. Or when you do, take out the battery when it's at full capacity. Because the battery is plugged in, the laptop is using power from the battery, not the AC. That means the battery is constantly going 99%, 100%, 99%, 100%, 99%, 100% etc etc. That is what we call "cycling the battery".

LiPo, Lion, and NiMh (all batteries, especially rechargable ones) lose charge over time. They lose them especially fast when they are being "cycled". They also lose them when they are never used.

The best practice for batteries is to charge them to full capacity, use it to nearly*** empty and then recharge them. When using the appliance for long periods and the battery is at full power, switch to AC power and unplug the battery.

I say to charge nearly empty because some batteries (NiMh does this) go into polarity reversal and get permanently damaged.

My take on things: get a new battery. Preferably something like a nine cell battery so that you don't run out of power when you need to use the battery.

Just remember to take care of it. A healthy battery is a working battery.

    I don't want to compete for that, yall can have it.
  • Varine Varine:
    @The Helper I'm trying. Once I am more prepared to be figuring out school I'll probably ask for your advice
  • Varine Varine:
    Right now I'm just trying to get through the pandemic and figure out how I'm going to pay for it, and figure out what I need to get a job at Best Buy instead of a kitchen somewhere.
  • thewrongvine thewrongvine:
    oy just catching up on the discussion above. @Varine yeah I usually alternate between claritin & zyrtec, depending on whatever my body decides to reject at the time lol
  • thewrongvine thewrongvine:
    the more I use it the less effective it gets over time as my body accustoms to it so I try to not use it every day
  • S songbird:
    Glad to see some interest in the IS3 NUON reprint. :)
  • The Helper The Helper:
    Thank you Carl for making that happen that just might be the spark we need.
  • Varine Varine:
    I'm confused and amazed that NUON and TWV's news postings are the things still active.
  • Varine Varine:
    Or Tom Mai, not TWV
  • Varine Varine:
    Whatever happened to Cheshire? Or Firecat, whatever his real name was?
  • Varine Varine:
    I've been using both claritin and fexofenadine or something like that recently alternately and that's been kinda working, I don't feel like my face is going to explode at least. Eyes are still itchy as fuck though
  • tom_mai78101 tom_mai78101:
    I dunno, haven't seen Firecat in a long while now.
  • tom_mai78101 tom_mai78101:
    By the way, we have new file attachment size limits now.
  • Varine Varine:
    Are they bigger?
  • tom_mai78101 tom_mai78101:
    Yeah, new max size limit is 64 MB, to accommodate NUON-Dome emulation.
  • Varine Varine:
    I don't think I ever ran into a file size problem before. What was it before?
  • Varine Varine:
    I've had file type issues before I think, but I haven't uploaded anything since like 2010.
  • The Helper The Helper:
    alot smaller than that basically barely anything and it would have been different then 2010 because of the forum upgrade
  • Varine Varine:
    lol I forgot this used to look different
  • Varine Varine:
    It's by far the brightest webpage I regularly visit, the first thing I usually do is try to figure out dark mode.
  • tom_mai78101 tom_mai78101:
    If you invert the colors, The Helper Forums looks amazing
  • tom_mai78101 tom_mai78101:
    It still has that blue theme at the top
  • Ghan Ghan:
    There's no particular hard limit to attachments. "Something reasonable" is preferred to "a size large enough to fill up the server disk"
  • B Badmanhop (Andy):
    I would be interested to.
  • tom_mai78101 tom_mai78101:
    Feel free to contribute to NUON.
