Created a replacement battery cover for the RFA-67 PetSafe Battery.

Use the old battery and cut the top open. I used a Dremel Tool to cut the plastic housing above the standard gasket. 

1. Cut open the old battery
2. Place the metal “nipple” into the base
3. Place Battery #1 Positive Side down
4. Place Battery #2 Negative Side Down
5. Place the metal “clasp” over the second battery so in goes to the side of both batteries and pokes through the bottom.
6. Screw on the top
7. Place in your PetSafe Wireless Dog Collar.
