    Force charge laptop battery?

    What I'm really asking:

    Is there a way to force charge or jump start a lithium ion battery?
    The battery is
    as07a31
    made by sanyo.

    Long story:

    I have a acer 4520, the DC jack was broken and was run on the battery til it was dead. The woman didn't have a critical need for it because she got a Mac Book. She gave it to me to repair, but I never got around to it and she never asked about it.

    You see where this is going don't you?

    1 year later, the mac book died, and no money to give to those con artist at the mac store to fix it. I figured I do the nice thing and repair the acer for cheap. Turn out the jack was expensive to get. 2$ jack 15$ for S+H. I looked around, found some for cheaper but the sites were questionable. I tried to remove the old one but I needed a higher wattage iron because my heat was quickly disperse over the pcb and components and was not melting the solder. I worked on it for awhile then gave up.

    Then I decided to look for the actual assembly and found the whole powerboard for 25$ + 7 for S+H on amazon. I figured by the time I get a hotter iron and pull the jack and place the new one and the uncertainty of heat damage and I might end up buying it anyway, seem cheaper to get the board.

    So I ordered it. Got it today, installed, LAPTOP NOW WALKS AMONG THE LIVING!

    Everything is working....
    except the battery.

    It seems to have a small charge for about 1 minute and then goes dead, then you plug it in and it charges for 1 minute then the light goes out. I don't remember if the light changes to green if it's fully charge or not.

    I figure the battery is good it's just got that memory effect from not being charged for so long.

    Therefore I want to exhaust my options before I order a new battery.

    Huh... I use it for 2 days no charge light. I go and take a nap and turn the thing off but plugged in. Woke up to see the charge light is on. I wonder what changed.

      Vostro 3400 (LA-K033P) won't charge battery, everything else ok
      by techfreak9356
      I bought a Vostro 3400 motherboard (LA-K033P) to upgrade over my damaged Inspiron 5593 (LA-J091P) board. Everything else is ok except for the battery. This battery I am using now is already a replacement one since I disposed of the bloated original one. Back in the Inspiron 5593 motherboard, the battery charges fine and is identified just fine. However, with the upgraded motherboard, suddenly the replacement battery is labeled as "Not a dell battery". When I borrow a similar battery from my colleague (which did not have replacements yet), it is identified and charges just fine.

      How can I charge that battery pack?
      by razenxd
      Hello,
      it's not a laptop/desktop related question but I figured that someone here will have the right knowledge.
      At work we use a few Aldebaran(now Softbank/United Robotics group) Nao Robots which they use some custom 6S li-on battery packs.
      Nao robots tends to draw from the battery even if they are shut down, and the BMS tends to be a little aggresive, if the pack stays on a turned off robot for 3 months it's gonna lock and will refuse to charge.

      Now, I have noticed a few things.
      The "dead" battery, while connected to charger and NOT Charging will...

      Acer a515-43 low battery charge voltage
      by ruletero
      Hi

      Acer A515-43
      LA-H801P

      Fail: Does not charge battery, has low voltaje on connector.

      Laptop didn't want to turn on, only charge led blinked.

      I found PQB5 (mosfet high battery charger) in short, voltaje in +12.6V_BATT was 19 v ...

      I changed it, changed PQB6 too and now battery charger voltage is 4.4V but battery is 3 cell, 11.25v, then is very low to charging.

      Laptop turns on without battery and works fine, but with battery turns on and turns off inmediately, I suspect battery bad but I don't know...

      Charge a L19D3PDA battery externally from the laptop
      by Klevjetack
      Is there a way to externally charge a L19D3PDA battery from the laptop. I have a broken charging port on my laptop and am trying to find a way to charge the battery for it. I have been doing some research and I have found that there is a module, TP4056, that can be used to charge Li-ion batteries. It says it is used to charge single cell Li-ion batteries. The L19D3PDA battery is a three cell battery. Is it possible to use the module to charge my battery and it would just be very slow? Or would that be a bad idea. Is there a different kind of module I can use to charge my Li-ion three cell battery?...

      Latitude 3301 not charge battery
      by dclass-pro
      Hi guys I have this dell that with the battery charged it turns on correctly, but if I connect the charger I get the charging symbol but it doesn't charge the battery.
      I found the shorted charger PU4401 ISL9538h that had pins 14 and 15 shorted and I replaced it. but it still doesn't charge.
      I noticed 2 things:
      1) without the battery connected if I connect the power supply, on the SDA and SCL pins of the battery I have 0V I measured the resistance with ground and it is very high, if I connect the battery I have 3v on the 2 lines.
      2) if I try to turn it on without the battery...
