    Charge a L19D3PDA battery externally from the laptop

    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?

    Frankly , it's better to repair the charging port , but , if you want , there's another trick you can do and usually i apply this trick for unused batteries for a long period . So basically , this trick is to reform a battery since When the battery level drop down to some critical point , the system will reject it as a bad battery .
    Anyway , with the tip of solder , pierce one hole in each side of the battery (the length opposite sides) gently to reach the positive and negative sides of it .
    Use any 12v adapter , 3.5A. preferably , to charge the cells .
    Since this trick wasn't specifically designed for your case , you have to monitor the battery temperature yourself . When you feel it's warmed enough , it would be at full charge .

        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...

        Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
        by Bowline
        My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

        Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

        My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
        The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
        I have tried multiple different Dell power adapters. My Dell...

        Adding a clock battery to action camera to retain date&time when changing batteries Campark X25
        by flat-earther
        I have a cheap action camera with an annoying trait, every time I change batteries the date & time gets reset and I have to set it again.

        To solve this problem I want to add a small internal battery inside it which will keep supplying power to the camera for a while while I change batteries so the date & time is retained.

        I have opened the camera and I think there is enough room to add something inside to accomplish this:

        The camera is powered by a 3.7V nominal single cell lithium ion battery.
        So I need to connect another battery in...

        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...
