Difference between JC03 and JC04 battery

[wi77ie]

HP Part #919701-850 for my laptop and on the battery it has JC03. Third party parts sites claim this part number as both compatible with JC03 and JC04 and some just say JC04 with the correct part number. As a tech good at sourcing information I cannot find any to explain the difference. Please advise with details or a definitive source that defines the designation and what it signifies and how it differs.

Thank you

I cannot be "definitive", but my unresearched guess, freely given, is that the '03' has 3 cells, and that the '04' has 4 cells, giving longer battery-life to the latter.

LOL color me embarrassed for not figuring that out. I just checked and my battery JC03 and 31W which is 3 cells. The battery online i saw was JC04 and specifically has the part number for the 42W 4 cell. Thank You

hi

I just bought the HP 250 G6 and I have a JC03 31Wh in it

When checking deeper on third partire, i can see that the 4 cells JC04 has 14.x Volts, while the JC03 has around 11 Volts.

Note :

1. 10.95V and 111.1V are compatible, they are in common use.

2. 14.6V and 14.8V are compatible, they are in common use.

3. the 11.1V(=10.95V) and 14.8V(=14.6V) are the different voltages, they are not compatible, please choose the right battery(Voltage) for your laptop.

So, I assume tyhat depending of the model you have, you have the 3 OR 4 cells.

The real question that HP seem NOT to answer is : is there a long life battery for the model having the same voltage

BUT maybe i am wrong and something escape me there ...

Hi

As HP is not willing to help on these, I finally got an answer that helped me understand how all that works

The voltage output on a battery has to do with how the cells are aligned in the battery.

Batteries where the cells are in rows of three are typically rounded to somewhere between 10.8 and 11.1, while batteries with cells in rows of four are typically rounded to somewhere between 14.4 and 14.8.

In some machines it matters which you choose, usually having more to do with the software in the battery that the voltage. In many cases though it does not.  They typically make note if it does and link to the other battery.

If you look at your charger it probably outputs 18.5-20v so even if your machine usually uses an 11v battery the 14v is still less then the output on the charger and isn’t going to harm your machine.

Hope this clear things up.

I will kudo that one
