My lazy ass never got around to selling them, and they've been sitting there ever since.
The research I've done would indicate that sitting that long uncharged would have ruined them. I am looking for the best and cheapest way to get rid of them. Any advice, other than "call Battery Boys", would be appreciated.

First off, you should NEVER connect new batteries with old batteries in a series as the BMS (battery management system) whether built into into the batteries or onboard the charger may either under-charge the old batteries or over-charge the new ones, You risk overheating, permanently damaged batteries, and fire. Lithium batteries may catch fire more easily when mixed but lead acid batteries can overheat and be ruined.
Secondly, call the county refuse company and ask them about battery recycling and pickup or drop off.
