Herb,
If I remember right, a Li battery cannot take being discharged below a certain point. Big warnings on my cordless drill about not using it until it stops but recharge it as soon as it slows down.
Partial charging and repeated “top off” charges are fine. Also they don’t discharge when on the shelf like NiMH and Ni-Cads did.
I would suspect the master switch left on is what killed your battery, not your charging of it. On the flip side, I don’t think it is wise to use a charger designed for a lead-acid battery on an Li battery.
Sorry for your loss, Li is nice until you have to replace it. L

A funny....guy who sold me the airplane(not to be mentioned) forgot and left the master sw on....so I took the tiny little battery out of its holder...noticing how light and puny it looked...never thought...Lithium?? But it was....and I killed it...or maybe it died over the couple of days it sat with the master sw on? 160 bucks ....ouch!! gonna go with a sealed lead acid and a new, larger holder...I am a bit surprised that a standard charging circuit for lead acid batteries could reliably and safely charge a Lithium product...Must have some electronics built into the battery?

Yep....when I measured the voltage...it was around .6 volts...before I put a charger on it....so I knew it was dead...lead acid or Lithium....This particular battery is sold on Ebay and Amazon....160 bucks...there bouts...Labelled "Balistic". An equalizer is available that plugs into the battery to be used ever so often... Ha!
The ad says that standard charging systems can be used... Herb
