Daily Drops IMPI Power 6V Lithium Battery 2 Pack (Compatible with SPC-100 Bark Control Collar) Includes 1 Year Limited Warranty

Great

Ordered this 2-pack of batteries from seller Daily Drops for a PetStop collar last May. Installed one on 5/22/15 and about 2 weeks ago it started flashing. I took it out and reinstalled it (from past experience, I get a few days more or longer if I do this) and then a couple days ago it started flashing again, so I'm putting in the other 'new' battery today. If I get 11/12 months out of this second one, I'll be very pleased. Batteries from other sellers, including original/local ones, have lasted anywhere from 6-13 months...quite a range, but the first one of these is at the upper end of the range I've experienced over approximately the last 8 years (same collar and dog).

I bought these in September, 2016. They are both no longer working. They are supposed to have a 1 year warranty. I have tried to contact the seller with no response so far.

Perfect for our dogs invisible fence collar, and a SIGNIFICANT savings over what the fence company was charging me for replacement batteries.

worked like a charm at a fraction of the installer's price.Update: These batteries worked like a charm, but were completely dead after about a month. So the savings you get are negated by the fact that you are buys 3 times as many batteries....

Needed these batteries for my dog's bark collar. Worked just fine and cheaper to buy 2 at a time

I have 2 dogs, so ordered this handy two pack of Pet Stop collar batteries. I replaced the battery in one dog's collar when the batteries arrived and it lasted maybe a month. The other dog's battery ran out a few weeks later. When I replaced it with one of these "new" batteries, it did not work at all. These batteries are a waste of money.

Came on time and work with our electric dog fence.
