What tool are you using - what size battery ?
Turbo speed on a leaf blower could easily use up a battery in 15 minutes ?

this is the 21"inch self propelled lawn mower with the 7.5 Ah battery and rapid charger.  I purchased in May and it has been working perfect up until the last couple of cuts.  I have always been able to cut the entire lawn which takes less the an hour to do with no problems. the charger is completely green but within less then 15 minutes the battery goes dead.

The 7.5 Ah battery on my 21" SP literally lass me the whole season considering my 1/8 acre cluster home lot. Mulching leaves uses a bit more energy.

very mush seems like a defective heat sensor. Put it in the refrigerator for 1h-ish and try putting it on the charger again (then in the mower once charged...). I didn;t believe this "fix" myself, but after trying it, it worked... quite few posts made on this lately...

heat sensor usually gives a yellow light, no just a short run time.

Or the charger could either be defective or needing a reset by unplugging and back.

Do you put the battery in the refrigerator or freezer for an hour.

Yes, the refrigerator where temps are usually between 36° - 41° if the thermostat is accurate.

Putting my bad one in the fridge overnight did nothing, FWYW

Sounds like a battery problem to me. To be certain, try a different charger to rule out the charger being the cause (if you have another charger).  If you don't have another charger, try power power cycling your charger by unplugging it, if you haven't already.
