Sanyo Tool Reset Bq8030 Datasheet. Battery capacity is stored as the remaining capacity reported through SBS divided by 2. Cycle count is stored as Cycle. Count- 1 (eg.: SBS value: 2. Eeprom byte: 2. 22)Remaining Capacity Alarm is stored as- is. A good place to start mapping. It's a good idea to reset the cycle counter.

Just 'adding' because this battery controller is already public. You have the (pdf) which tells you the pin combination to enter the Boot ROM and most of the command set (how was the actual read command missed? Then there are open-source flasher tools like. You can also use Google to find the passwords because you WILL need passwords (at least with this firmware) and that is after you set the correct pins to the correct states to enter the boot rom. Yeah, overkill.

But since it's all out there it's just a matter of coding up a tool for. $ smbusb_scan -w 0x16 ------------------------------------ smbusb_scan ------------------------------------ SMBusb Firmware Version: 1.0.1 Scanning for command writability. $ smbusb_comm -a 0x16 -c 0xFF -w CDAB -b $ smbusb_comm -a 0x16 -c 0xCF -w 3412 -b $ smbusb_scan -w 0x16 -e 10 ------------------------------------ smbusb_scan ------------------------------------ SMBusb Firmware Version: 1.0.1 Scanning for command writability.

Just don't scan it too much because writing the wrong thing to the wrong command will hang the controller and/or the entire bus which the SMBusb won't like too much either. (The Boot ROM in this chip has zero error handling.) Some coding later.

So the battery of my DELL XPS17 L702X suddenly died and that really sucks. Dell wants to get 150+ € for a new one and i don't have that money as a student at the moment. So i want to fix it myself. Brand: SANYO / DELL Battery type: R795X Li-ion Voltage: 11.1 V Cells: 9 Capacity: min 7.65 Mah Code on battery cell: PEHZ9 14983 Battery controller board TOP: High res: Battery controller board BOTTOM: High res: Batt: High res: and a weird component: High res: Some sort of diode or something? I'll have to test if i can charge these cells manually and look if they are still alive using my turnigy accucell 6. And if they are dead which one to buy and replace them with. That 'weird' component is probably a thermal fuse (or switch) which opens when the temperature exceeds the safety temperature.
