Cannot locate 2505k ni-cd batteries for my 2512 3/8 impact wrench

You can get them online or through a IR dealer like Northern Tool and Equipment.

Ever use Google-- to learn things
or You Tube Video

I have a 12v an 18v Dewalt I can charge them both from the same charger

Are you sure you bought lithium cells? In your camera you should use Ni-MH batteries. The SNB-2512 could be very expensive, but normal Ni-MH from any brand should work fine.

Depending of what you use, always be sure all batteries are the same, charged and suited for your camera. Most of the time even new Ni-CD rechargeable batteries won't work, because the voltage is low, according to NiMH or alkaline batteries.
Always charge NiMH batteries before using them for the first time, or if they have not been used for a long period. 3 months is a very long period.
Always charge sets of batteries (2 or 4) together.
Do not use alkaline batteries unless it is absolutely necessary. In some cases, alkaline batteries may have a shorter service life than NiMH. Alkaline battery performance is limited, especially at low temperatures. The use of NiMH batteries is recommended.
Never use manganese (Zinc-Carbon) batteries in your camera.

IR 2507 Charger is used for the 2505 battery...which operates the IR 2512 3/8 Impact

go to eReplacementParts.com : Power Tool Parts and Tool Repair

If its old maybe you need new battery, becouse thats a problem with rechargeable batteries, or you may need a new charger...

Unfortunately there are no repairable parts in a battery. Once a battery is dead it's usually best to find a good recycling center for it, most The Home Depot's have one. Makita lists battery 1234 (Part #193157-5) for this tool but it's the old Ni-MH battery. I'd use battery 1222 (Part #192598-2), it's the better Ni-Cd battery.

no dont use rechargables,just use litium energizers,and you,ll be fine.hope i helped.p.s i sold digital cameras for 3years as a photo lab supervisor,and i have this camera myself,its awesome.
