Re: Lithium Ion Battery Manufacturer Links
When I needed button cells I went with this company.
Good spec sheets and sent samples when I asked.

Lithium Ion Battery Manufacturer Links
Since we have had a number of reports of faulty lithium ion battery packs (particularly Sony ones), there should be a list of lithium ion battery manufacturers:
Panasonic: www.panasonic.com.sg/industry/
LG Chem: www.lgchem.com
Samsung: www.samsungsdi.com
Sanyo: www.sanyo.com/components/
I am still looking for manufacturer links for Toshiba and Sony lithium-ion cells.
Anyone who knows of other lithium ion battery manufacturers, place the manufacture links here!

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... -
I have had with regular AA batteries that leak this meter is expensive new I already replaced the battery battery clips once and the same thing happened again and I am tried of so it is getting modified to accommodate lithium ion batteries that are the same size excluding the positive terminal and removing the battery clips I will have enough room for the BMS protection board
I going to put 3 lithium ion battery in parallel with the BMS protection board and a way to charge the battery externally and heat shrink the battery pack and use a JST connector so I easily remove the battery... -
Hello everyone,
Mark and model: ASUS X571
Symptoms: not turning on. There is only the LED battery indicator working. The owner of the laptop told me this problem arrived one week after having changed the battery. He then managed to power on the laptop only once, and then it never powered on again.
Tests already made:
- Battery is charging when laptop is plugged in. The LED battery indicator turns white after a couple of hours of charge, indicating that battery is fully charged. However, laptop won't turn on anyway, with or without AC plug.
- I have removed... -
I have a drill and battery but no charger so I bought a "universal charger" 120ac in ... 12vdc out (not really universal in lithium world). Anyway it has three contacts, positive, negative and "T" (temperature sensor). I connected those contacts to the contacts on the battery. No charging happened and only the status light is on (green solid) which the label indicates "100% charged".... but the battery isn't near that at around 9v and dying. There doesn't appear to be any difference whether the battery is connected or not. I got suspicious and pulled the... -
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.
