2 Pack, 6 Volt, Lithium Battery Module, Works In The IF-275 & PUL-275.
Customer Rating: Summary: Petsafe 6-Volt Lithium Battery (2 Batteries per Pack) Comment: VERY QUICK SHIPPER.
This was a special bargain, because of the lowest price I have seen in a couple of years for these batteries - but I also got 4 packs for the price of 3.
GREAT Customer Rating: Summary: Not Necessary Comment: This item was matched with the bark collar and made it seem that it would be needed, however when we received the products these batteries don't even work w/ that particular bark collar. Customer Rating: Summary: Wrong battery Comment: I don't dislike the battery as such. It's just that I bought it because Amazon says customers often buy it with Innotek pet collars. The battery doesn't fit these collars, and Amazon should not let this pairing mislead people like me. The Petsafe battery is a disk you screw in; the Innotak collars take a conventional cylindrical battery. I wrote to customer support about the matter, but received an automated reply that didn't resolve it. I note the PetSafe battery is still being paired with the Innotek collars. Customer Rating: Summary: Wrong battery! Comment: I ordered this battery in combination with a collar on the recommendation of Amazon. I love the collar. The battery, however, is the wrong size so I can't use it. Customer Rating: Summary: Doesn't fit the bark collar Comment: I ordered the collar and 6 volt batteries together. The problem-the collar takes two 3volt batteries.
