rebuilding laptop battery packs

[Jack Coats]

Batteries plus rebuilds batteries for power tools, etc.
They have a local store in Nashville that does rebuild battery packs.

They typically have newer style batteries that can put a higher
power density cell into the packs.

shows they have 4 stores in Mass.
