If your collar takes regular AA batteries, then yes, you can use lithium or rechargeables.
I would think it would be cheaper to go with the rechargeable over the lithium as you will get more use out of the rechargeables.
Just make sure you get some like 2500mah compared to buying 700mah.
They sell the chargers where you can recharge 4 of them in a 12v outlet in the truck or plug it into the wall at home to charge.
