How to repair IBM thinkpad 240 batteries (02K6608,02K6606)

If you follow the procedure here and kill yourself I will consider it a gift to the gene pool. You are on your own. Anything stupid that your do is your own fault. My IBM thinkpad 240 battery (02K6608,02K6606) died the other day. The battery is quite clever it has a bq2040 smart battery interface chip, which in turn has an eeprom in which it keeps track of the battery. First the actual battery board prepared in the usual way using chalk mix because IC numbers don't scan. Large version Click on a chip for more info. Connections to examine/modify EEPROM.

Charging Lithium-Ion Batteries – Battery University

Charging and discharging batteries is a chemical reaction, but Li-ion is claimed to be the exception. Battery scientists talk about energies flowing in and out of the battery as part of ion movement between anode and cathode. This claim carries merits but if the scientists were totally right, then the battery would live forever.

They blame capacity fade on ions getting trapped, but as with all battery systems, internal corrosion and other degenerative effects also known as parasitic reactions on the electrolyte and electrodes till play a role.

Comments On September 21, 2011 at 12:51pm Joe Accetta wrote: There is yet another and quite accurate means of measuring SOC in open port lead acid batterieis through the use of refractometry.

Measuring State-of-charge - Battery University

The index of refraction of the electrolyte is directlly proportional to the SG. JSA Photonics has developed an in-cell immersion refractometer that yields accurate 24/7 SOC information along with cell temperature for monitoroing and temp correction and in some instances electrolyte level.

The compressed .tgz archive can be opened with WinZip, yielding an .iso CDrom image. It contains a minimalistic bootable Linux based on RedHat 8, text mode (no X) with the i2c-progs packaged in, a shell script presenting a menu, some basic goodies to facilitate freestyle improvising (vim, mc, basic system environment, five unrestricted shell consoles at ALT+F2 to ALT+F6), a bit of documentation. Either way, you'll need to solder the necessary wiring probes for the parallel port (see below). Make an inexpensive Lithium-Ion Battery Pack. If the batteries are the heart of the Li-ion battery, then the PCB is the brain.

Make an inexpensive Lithium-Ion Battery Pack

This is the one I used. It was 6.50 at Batteryspace. It was easy to solder wires on the PCB. It is designed to stop solder from spilling onto the rest of the board. PCBs come indifferent varieties depending on number of cells, voltage, and capacity. Here are the specs for the one I used and I will explain what everything means...

Ever needed to charge your phone on the go?

Heavy duty portable charger for usb devices (phones, iPad, etc.)

Can't find a wall socket to charge your iPod? Whenever I'm away from home for an extended period of time, I would charge my phone and mp3 player from my laptop. This way, I get about 3 or 4 full charges out of the laptop battery and I could leave the phone and mp3 player chargers at home. But carrying around a laptop just to charge a phone and mp3 player seemed a little excessive. The Anatomy of a Protected Battery. The Anatomy of a Protected LiIon Battery A protected battery will (hopefully) include the following protections: PTC, protect against over temperature and indirectly over current and will automatic reset.

The Anatomy of a Protected Battery

CID or pressure valve, will disable the cell permanently if the pressure is to high in the cell (Can be due to over charge). PCB will protect against over discharge, over charge and over current, depending on design the PCB will reset automatic or when placed in a charger. Unprotected batteries are missing the PCB protection, but usual has the PTC and CID.

The above drawing illustrates how a protected cell is build. The battery is a 18650 battery, with this name it is supposed to be 18 mm in diameter and 65 mm long. Battery Ventures.
