    Ebike battery gone flat

    I have an ebike that runs off of a 36v 2A battery, its some special battery for it. It has a charger built onto it and it runs off of 120v, its basically a little psu. It is probalby the battery just gone bad, it is 9 years old and a lead-acid, but is there some off chance that it is the charger? It has mostly bad caps, not physically gone bad, but the primary is a Hitatchi, and the secondaries are a mix of RB, Teapo and Tayeh. Then theres some cap way over by the dc output for the battery that is a big Teapo. I looked up the UL, and its made by High Power Tek Inc. Is there any way I could trick the psu into charging the battery even though it says its full (tested by putting it in the bike and theres just enough power to make the motor twitch and the horn buzz,)

    Or is there some way I can hook up a computer psu to it?

      a 9 year old sla is recycling fodder.
      time to replace.
      open it and you will likely find 3 12v batteries.

          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...

          A2337 not working with flat battery
          by reformatt
          Looking for some advice on a 820-02016 board as I don't have much experience with these M1 machines. Learning the nuances of them as I go.

          So the history of this machine was it had been in a bag where a bottle of water leaked. Presented as dead about a month ago, corrosion was mainly around the battery connector and it's sub-PCB. Some corrosion was noted on the board around UC300, CC325, CW1C7, CW1C8. That was it really.

          Now without battery connected, USB-C will stay at 5V and cycle between 0 and 120ma. PPBUS_AON is cycling between 0 to 12.3V. If battery is connected,...

          Acer Aspire 5 A514-55 - won't power on, no charger LED, battery not flat - usual suspects?
          by DenK
          Dear all, I am trying to troubleshoot an Acer Aspire 5 A514-55 that won't power on. I'll describe the symptoms and my findings so far, and I would like to seek guidance and suggestions on possible suspects in terms of cause/component failure. My initial thoughts are battery charger IC and/or ideal diode/MOSFET (that switches between incoming DC and battery power), but I could be totally wrong on this.
          1) Laptop was working fine on battery, then user realised battery was running low. Plugged in AC adapter but noticed it was not charging (LED on AC adapter plug did not light). Eventually shut down

          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.

          ISL88739AHRZ ISL88739 Laptop Battery Charger Datasheet
          by Document Archive
          The ISL88739 & ISL88739AHRZ are a highly versatile combo battery charger
          configurable for operating as either a Hybrid Power Boost (HPB)
          charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or
          4-cell batteries. Both configurations allow the battery to work with
          the adapter together to supply the system load when it exceeds
          the adapter capability, referred to as system Turbo mode. HPB
          charger configuration reverse-boosts battery energy to the system
          bus to help the adapter provide the system power in Turbo mode.
          NVDC charger configuration...
