If you can get them for free (or for the recycling fee, which you can get back later), sure, collect all you can get. You could put together a simple capacity testing rig -- like this one -- and spend the winter rounding up recruits for a pack that will be good enough to test with.

What did you do for your existing pack(s)? How did you get them?
All the "good" batteries are cast-offs from other EV owners in the Ottawa EV group. The first "decent" pack was made up of the "weaklings" that a Ranger EV owner would periodically evict when his pack monitor showed them falling on their faces before the others.

The batteries we have now are quite good - about 2-3 years old, replaced by a Jetta owner who was upgrading from floodies to AGM's, if I'm not mistaken. These are good enough to serve the ForkenSwift's modest range needs for many years to come.

there are tons of perfectly good deep cycle batteries out there, but I either can't find them or they are too far away.
Joined an EV club yet? Marinas, golf cart supply/service co's, industrial floor sweeper / scissor lift companies... They're out there somewhere.
