Roy,
Sorry for the delay, I saw something shiny and got distracted... They have
two " D " size batteries. The 4.5 AH is a NiCad ( 1.25 VDC ) with welded
tabs at either end. They also have a 2.5 AH Sealed Lead Acid Gel Cell ( 2
VDC ) with two tabs out the same end. I believe the first one is made by
Cyclon. The other sizes ( i.e. AA, etc. ) are NiCad and other non-lead-acid
families which I have used to replace dead cells in battery packs ( like for
my Milwaukee cordless drill ). Hope this helps.
Best regards, Steven

Are these lead-acid though? Or something else...
The different types are not at all interchangeable, at least as far as charger is concerned.
