The OEM batteries are all old and were affected by the 2006-2008 Sony recalls. Generally with these Sony recall Dells, the battery was replaced under the recall (with a much more failure sensitive one)or it was safe and has the old BMS. Yours sounds like a safe pack with the old BMS based on the fact it didn’t give you a permanent failure POST warning and “lock out” the battery.

The OEM batteries are all old and were affected by the 2006-2008 Sony recalls. Generally with these Sony recall Dells, the battery was replaced with a newer battery that is much more sensitive (and doesn’t last anywhere near as long as the old Sony packs). Based on the fact the BIOS didn’t throw a fit and a permanent battery failure warning at POST, it sounds like you have one of the old Sony batteries with the old BMS. The other clue that it’s a Sony battery is the fact it still has some life left. The recall replacements didn’t last anywhere near as long.
However, those “safe” Sony batteries from the recall period are all 10+ years old and it’s a matter of when these old packs fail. They will all die, even if they have run this long before it got to the point problems come up. I have one of these “safe” Sony packs in a old HP Compaq and I have weird graphical issues with that only show on battery only power but not with the battery with DC power. I’ve chalked it up to the battery being old and finally dying.
It's so old it only has ~6,000mWh left so I think it isn’t providing enough power to the video subsystem. It hasn’t shown the correct number when I look at it specifically for a while, so I think it’s low enough the BMS can’t tell what’s left with any level of accuracy. Once all of these packs get that low they may or may not keep going.
Anyway, take the battery out and run the notebook that way. If it works without the battery, you have an original battery from 10+ years ago and it’s dead.

Generally with these Sony recall Dells, the battery was replaced under the recall (with a much more failure sensitive one) or it was safe and has the old BMS. Yours sounds like a safe pack with the old wide failure range detection BMS based on the fact it didn’t give you a permanent failure POST warning and “lock out” the battery.

However, those “safe” Sony batteries from the recall period are all 10+ years old and many of the survivors are dying. It doesn’t matter WHO sold the laptop; I have one in a old HP Compaq that works but I can’t get it to display the correct mWh capacity no matter what I try but I’ve estimated it to be ~6,000mWh left, give or take.The pack works, but the BMS can’t properly register the true capacity anymore because it’s so low. I had issues with the graphics and Ive never noticed with DC power, but it persists on the battery. I think the poor capacity is causing problems despite being (somehow) functional.
