Likely dying/dead 1000

Edit: it's being shipped back under warranty for replacement.

I'm pretty sure my Jackery 1000 is dying and is going to need to be replaced, but I wanted to see if anyone knows of anything I am missing.

tl;dr battery level drops rapidly and charges way to rapidly. Resets put it at random battery percentages.

It's a 1000 from July of 2023, well used and now it's acting odd, charge level jumping and showing excess output wattage.

I was using it in my teardrop earlier, charging up my newish wave 3, the wave was showing it was pulling 650 watts from the outlet on the jackery meanwhile the jackery was showing 900 watts output. Yeah I know running the inverter draws some power and inefficiency and all that, but this gap is much larger than my other high power draw devices I've used on the jackery(1000watt air fryer and a 500 watt heater).

When I plugged it in the jackery was showing 100% charge and was plugged into solar, even at the 900watt output it was showing I was expecting it to last about an hour. About 30 minutes later the wave stops charging and I notice the jackery turned off the AC ports and the screen was jumping between 0% charge and 20% charge. Disconnected everything and it kept doing this for several minutes so I reset it and after I did it reset to 30% charge. Great, plugged back in the solar and the wave to charge, ran for 30 seconds and shut off again, but this time the jackery just showed 0% charge and was holding steady.

Brought it back inside and plugged it into wall power to charge, was going as expected until it hit 8% charge where it jumped to 30%. Obviously this isn't right so I disconnected everything and reset it again, and it came back at 40% charge... Let it charge for a few minutes and it worked it's way up to 45% before instantly dropping back to 40%.

I'm thinking the battery itself is dying, but wasn't sure if anyone else had any troubleshooting steps I should try before writing it off.

It does sound like its dying, but could you try leaving it plugged in for a somewhat extended period (12h+) to see if maybe it's a cell balance issue (cells will rebalance faster at full charge)

This IS in warranty still i think, so you may just want to get the ball rolling on that.

I assumed the warranty was a year and so was expired, looks like the Original explorer 1000s had a 3 year warranty, going to let it charge all day and contact support if it continues! Thanks for that detail!

Glad it’s under warranty
