Review: Long-lasting batteries for PetSafe collars! - These PetSafe batteries are exactly what I needed for my dog's collar! The 2-pack is great value and having a spare on hand means I'm never caught without power. The lithium batteries last significantly longer than the alkaline ones I was using before. Installation is simple and straightforward - they fit perfectly in the collar. The waterproof metal construction is impressive and holds up well even with my dog's outdoor adventures in all weather conditions. I've noticed consistent performance throughout the battery life with no sudden drops in power. The collar functions work reliably with these batteries. They maintain charge for months, which is much better than generic batteries. The quality is clearly superior - worth the investment for reliable pet containment. Easy to store extras. Perfect for anyone with a PetSafe collar system. Peace of mind knowing my dog's collar will work when needed! Review: Best choice for pet safe - Great batteries. They fit in well, they’re easy to change, and they seem to last forever. They’re smaller than a quarter so they don’t take up much space, which is nice for storage. They work well - I’ve never had issues with one going bad or malfunctioning. ## Features - Replacement Batteries: Multi-pack 6 volt RFA-67 lithium metal replacement batteries included - Compatible Petsafe Collars: Works with Basic Bark Collar, Wireless Pet Containment System, Stay & Play Wireless Dog Fence, and Deluxe UltraLight In-Ground receiver collar - Long-Lasting Battery Life: Each battery can last 1-3 months, depending on use - Waterproof Battery: Designed for moisture-resistant outdoor use - Quality Promise: PetSafe brand has been a trusted global leader in pet behavior, containment and lifestyle innovations since 1998 to help keep your pet healthy, safe and happy ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0009811TW | | Amperage | 6 Amps | | Antenna Location | Radio | | Battery Capacity | 6 | | Battery Cell Composition | Lithium Metal | | Battery Cell Type | Lithium Metal | | Battery Weight | 2.9 Grams | | Brand | PetSafe | | Built-In Media | 2 Batteries | | Compatible Phone Models | PetSafe 6V Lithium Battery | | Customer Reviews | 4.6 out of 5 stars 36,614 Reviews | | EU Spare Part Availability Duration | 2 Years | | Global Trade Identification Number | 00729849105423 | | Item Dimensions | 1 x 1 x 1 inches | | Item Type Name | Battery | | Item Weight | 10 Grams | | Manufacturer | Radio Systems Corporation | | Model Name | RFA-67D-11 | | Model Number | RFA-67D-11 | | Number of Batteries | 1 Lithium Metal batteries required.

Normally you should be able to twist the battery out using a coin. If you could reach out to our Customer Care team, we'd be happy to see how we can help! **Q: Is the Pack of 3 for 6 batteries or 3?** A: I get the pack of 2 so not sure about the 3 pack **Q: How often do you find you need to change your batteries? If every 6 weeks normal?** A: The last package of 2 I got only lasted 5 weeks. That is only about 2 1/2 weeks per battery. That's not very long for the "name brand battery". I'm going to try an off brand next & see if they last any longer. Maybe I just got a bad batch? My first set of 2 seemed to last about 3-4 weeks each. **Q: I assume there sis no expiration date? I was going to save some $$$ and buy a 10 pack - I only have one dog. Anyone with shelf life knowledge?** A: Hello Kleecker, the RFA-67d-11 batteries have a 5 year shelf life. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Long-lasting batteries for PetSafe collars! *by D***A on January 21, 2026* These PetSafe batteries are exactly what I needed for my dog's collar!
