Re: Universal Battery Analyzer tool NLBA1

Do not make confusions, laptop batteries are using SMBus protocol and not I2C. It is based on I2C but not I2C, you can read probably in some cases the SBS report but I would definitely not recommend you to program the SMBus chip using SPI protocol, you can brick the chip.

Re: Macbook Pro A1502 Adaptor Shorted When Battery Attach

"Unit works on Battery Mode" -> this tells us that the battery is discharging fine and the motherboard can be powered from the battery.

"Unit works on Adaptor Mode" -> this tells us that the motherboard can be powered from the AC adapter.

None of the above scenarios does test the charging path: charging block of the motherboard and charging block of the battery pack.

"But When Adaptor and Battery both attach" -> this scenario uses the charging modules...

I have just created a beta version of the Remote Reset Option. Remotely I can unseal all Apple batteries and all BQ30z55. If you have an NLBA1 device just connect the battery and ask me to unseal it. You just need to press one "Connect to server" button....

Re: Universal Battery Analyzer tool NLBA1

Non genuine batteries have completely different chips, they are using their own Chinese chips which run poor firmwares. NLBA1 does not support Chinese chips for Reseting. In principle I won't recommend repairing laptop batteries which are non genuine.

This is a good point. This feature can be added in NLBA1 PC Software. Something like genereting a pulse pattern like -3A for 100ms, 0A for 500ms then -1A for 1s and so on.

Oooo yes, non genuone batteries have poor hardware, even...

Re: Universal Battery Analyzer tool NLBA1

Exactly, you need a laptop for each battery type, if you have 10 different batteries you need 10 laptops to test them

Laptop battery chips have Failure Flags. If at least one failure flag is set then the chip will never ever output voltage, the battery cannot be charged or discharged anymore since the fault is present. So, from my point of view the chips are in two states: Locked (with at least one PF set) and Unlocked (no PF set). If the chip is not Locked then you still can charge the battery, it does...

Re: Universal Battery Analyzer tool NLBA1

Exactly, there are tens to hundreds of parameters that could be updated when you are working with laptop battery repair. Repairing laptop batteries is a top secret domain with very poor information on the public. NLBA1 team is capable to reprogram the chip parameters, we can even program the chips to support higher capacity, including the latest high voltage cells. That's why I am saying the support is the key in this field.

NLBA1 charges the batteries like the motherboard does and not like a Lab Power supply,...

Re: Universal Battery Analyzer tool NLBA1

Please don't deviate, we are discussing about charging a laptop battery, not charging cells. Cells are cells, laptop batteries are laptop batteries. I have already explained that a laptop battery cannot be safely charged by a lab power supply. More, there are batteries that even stop the charging or discharging if a Charging or Discharging SMBus commands are not sent, see Dell for example. A laptop battery is a smart battery and must be always charged by a Smart Charge. Another example, take an Apple Macbook battery and try...

Re: Universal Battery Analyzer tool NLBA1

Did you try to repair Dell batteries bq304xx chips using be2works ? There are many chips on be2works website that I guarantee they are not supported.
Another example, try to clear PF errors from a Lenovo BQ8055A or BQ8030A using be2works. Even UBRT does not work for BQ8055A.
Also, try UBRT on BQ40z695, they claim it is supported but not.

I am not teaching you at all. Which workaround I don't know ?
If you want to say that you are safely charge a Dell battery using a lab...

Re: Universal Battery Analyzer tool NLBA1

NLBA1 team could offer remote unlock even for BQ30z55.
You are mentioning about BQ30z55 but why don't you mention about BQ304xx family used in tons of Dell Laptop Batteries ? This family is not supported by be2works too.

The new family BQ40xxxx is much more important. Not supported by be2works but supported by NLBA1.
Do not forget that NLBA1 unseals all theirs chip in 3-4 seconds why for be2works you need to discharge the battery (waiting for 2-3 hours). They don't have the full algo for unsealing, just...

Re: Universal Battery Analyzer tool NLBA1

NLBA1 device is an advanced analyzer. Reset Option can be used for Chip Reset and Programming.

The mentioned above names are only software, how do you charge a laptop battery ? or to calibrate ? or to discharge it ? or to measure the real capacity ?
P.S. UBRT costs up to 1000$ per year with almost 0 support.
be2works support is very poor (check their forum).

bq40z451 does not exist.
Newer chip family bq40zxxx is not supported by be2works at all, same for bq40xxx...

Re: How to repair a laptop battery (chip reset)

There are already libraries for Arduino that can read laptop battery information over I2C. Note that the communication protocol is SMBus, it is very similar to I2C but there are still differences. You can read more chips, not just BQ family. My question is, what do you plan to do ? just reading the parameters ?...

Re: How to repair a laptop battery (chip reset)

There are 2-3 softwares, just softwares that cost from 350$ worst one to 1000$ a good one. No support included, actually no English to poor English.
Maybe you know another device/product, just paste it here.

Using a Windows program you have access only to the SBS standard commands like reading few information CycleCount, ManufacturerDate, ManufacturerName, FCC, etc. But you won't have access to the SMBus routines to send any command like Unsealing the chip or programming it....
