Husqvarna Batteries

[Bill B]

I inherited a Husqvaarna battery operated tool system, chainsaw, leaf blower, and string trimmer.  3 tools, 3 batteries.  The history of these batteries is suspect.  Kept in an unheated garage with temps into the high 30's. 

All batteries will charge to "full" with no error code on the charger. But, and there is always a but, when used, all batteries will fail (tool stops working) after 4-5 minutes uses of use.  When I slap another battery in the same result.  But, 😩, after sitting a few minutes, 5-10 minutes,  the battery will run at full speed, for 4-5 minutes and fail again.

I'm assuming the batteries are toast.  Yes/No?  If they are toast, any resource to have them rebuilt?

We've been using those saws at work for a few years and the batteries have held up well. Some chargers have crapped out. Something is wrong with your batteries or maybe the chargers have gone wonky
