Well, now select Toshiba in the pinout area, and enter in search "PA3533U" part number to find correct pinout.
It has MAX1781 chip with Panasonic firmware, and could have some communication issues of Dynamic parameters, so read only Static area.
I finally got it, thank you so much for your help. I hope this one is a strange one, Looks like two bad cells. this is what I have been looking for.
It was in sleep state due to underdischarged cells 1 and 2. Such batteries first should be waked up to establish communication. Wake up means applying voltage to the Pack+ terminal externally using "Power On" button.
About this one battery condition, Cell 1 should be replaced for sure (by same type, manufacture period etc), Cell 2 could be recovered by precharging with small current over 3v, then balancing to same level as Cell 3.
@djibattworkshop I now have 10.0 volts and both lights are on
In my recommendation steps, it was clearly stated you have to press the Power On button. So, as I expected, the device is in good working condition.
@djibattworkshop The chip shows locked now and it said this chip was not supported. I want to try working with this battery and go through the remote reset but should I
change the battery first then balance charge then unlock the chip?
I want to try working with this battery
MAX1781 is not the best choice to start learn battery repair kitchen.
Look on website supported chip list and find a battery with any of listed controller.
and go through the remote reset
Remote Reset Server does not support MAX178x chips.
@djibattworkshop thanks I discard this one for now and start with something common.
Since it's a china made replacement battery most probably the chip is not MAXIM at all.
And anyway MAX Panasonic firmware has the issue wit losing communication when it reaches the cell voltages and here everything seems to be fine.
Is there any chance to open the battery and make a photo of the PCB?
