4lr44 6v Bark Collar Batteries – Durable Replacement Battery – Great for Dog Training - Safe for Small Vibrating, Static Shock, and Citronella Dog Training Collars – Set of 5

We use these for our dog bark collars - work great and will buy again!

I don't like the size of the collar. Too large for a 10lb dog.Batteries only lasted about 3 weeks. I only use the collar a couple times a week.

Great value...always keep a pack on hand in our RV for road trips.

seem to last well

Order is for package of 5. Only received 3Batteries. Package tore up and taped. Batteries just floating around in the package. Either employees don't care or can't count. Very disappointed.

Funcionan bien

Worked great!

Seems like they run out of power quickly.
