I have anywhere from 6-10 projects going at once and often have messy working areas. Sometimes there are victims. The latest victim was a Dewalt 5AH XR Battery that took a dip into 2 quarts of used diesel oil. Time slowed as it careened end over end and was completely immersed. I did manage to fish it out quickly, set it outside for 2 days to drip, brake cleaned it. The battery meter still lit and shows 1 bar. Opened to see the carnage and the batteries, circuit board and bits were lightly covered. It lived a hard life chopping cedar, and will live again after recycling. RIP.

That seems like something I would do!!! Or, more correctly, would happen to me.
A bit hard to tell, but I'm fairly sure those are 18650's in that pack, correct?

The older style should be 10 18650's in the 5ah.
That'll buff out in the dishwasher.

I'm not sure of the battery type, but they have been extremely reliable. Buying 2 more to replace soon.
I got lucky several years back with knockoff 4ah ryobi batteries they have to be 6 years old and perform as if I just bought them.
Have you done the used oil test?
Can’t say I have I don’t keep battery tools near automotive fluids lol

I have some DeWalt 20V batteries from 2012 that still work fine. I bought two knock off 20Vs that started oozing within a month, then pooped the bed completely. Waste of money!
OF all my REAL batteries, I did have one die, DeWalt just wanted a picture and they sent a new one no other questions. I keep my batteries in a place with not much temperature swing and pretty constant humidity. I think that helps a little but not relevant to the used oil test!
My knock off Milwaukee 12V batteries are king of knock offs honestly. Waitley branded I think

For a replacement try one of the Power Stacks. I'm a believer now with 2 little 1.7's and one beast 5.0, they are really good.
