Bolt Battery Capacity tracking

I started a Google sheet, that anyone can edit, to help track users Bolt reported Battery capacity. I previously posted a link to it in one of the threads but it quickly became buried with other posts. To make it easy to find and contribute to I am giving it it's own thread.

I think another important column to have is temperature. From the information I have read and graphs I have seen, capacity of the battery is dependent on temperature. I don't know if the software reads battery temperature, but ambient temperature could be used. My battery capacity has always been low and I think it would depress me to start logging it. I haven't seen much degradation and I don't want to stress over it. I am at 45,000 miles and I still use hilltop reserve and drive my Bolt 130 miles a day. On a good day I have 35% capacity left and on a cold day I have 20% capacity left. I guess if it degrades I will just charge to 100%...

I've posted two measurements: when I first began using Torque Pro, and recently when I crossed 10,000 miles.

Which capacity calc are y'all using? ((A*256)+B)*0.035 or ((A*256)+B)/30?

the default calculation assumed by the author of the Bolt PIDs table, I have not modified the calculation

Feel free to enter a temperature column if you like and specify what temp should be logged, I have not recorded that but guess I could look at historic ambient temperatures for the dates I logged the capacity data...

thanks for the forum members contributing some data points, glad to see @GJETSON that your battery capacity has bounced up a little...

Interesting, but not useful. Now if my usable capacity went up, that would be nice.

looks like @GJETSON has been diligent about tracking and logging his Bolt battery capacity, and others of us, not so much ;-) I just updated mine today, if anyone else is interested in logging or just reviewing the data collected to date please see my first post in this thread.

I went to your link on how to read battery capacity. I have never used an odb, etc. so this will take some study.
However, I have a question. From previous posts, I understood that with a 2019 Bolt you can not read out the battery capacity with a odb. If this is true, then there is no reason for me to buy a odb. Can you or someone else let me know if you can now read out the battery capacity on a 2019 Bolt?

Thanks for any help you can give.
