Enerpe RFA-188 Replacement Battery High Capacity Compatible with PetSafe Collars (4-Pack & 8-Pack Options)

these work fine in the pet collars that take rfa-188 batteries . they fit fine and securely.if your pets need a new battery , dont wait , buy these now .

These are a great lower cost option. They fit and work well unfortunately the collar strap broke soon after my purchase and haven't found a way to replace it so I can't use it but the batteries are great.

Going on 2 weeks of using one and it's been great so far and my cat uses this everyday

Fit my old petsafe dog collar with no issues.

I've had my cat radio fence collars for many years now and have always bought replacement batteries by the 10-pack - just the battery. After a while the original battery holder's opening slot got worn out and it was hard to turn on/off the collar every day (collars come off of the cats in the evening at curfew, they go on in the morning when the doors open).These battery holders (which come with fresh batteries) are just like the originals. As I wear out the slot, I replace the holder.Just like the originals, you can pop off the ring at the bottom of the holder and you can replace the battery with a CR1/3N replacement, but since these are $1.78 each and the batteries anywhere from $1.20-$1.80 each, it's not as compelling to do that as when you were otherwise reliant on the oem charging $10 per new battery+holder.
