B3V 1A Replacement Battery High Capacity Compatible with High Tech Electronic Collars of MS-4 and MS-5 Pack of 12

Pretty decent battery life, and quality for your pets collar to use on their electronic doggy door. No need to pay the extra high prices for the original name brand one.

Quick delivery. The batteries works well for our doggy door.

Very Satisfied: fits perfectly and good battery life of about 4-6 weeks with a HiTechPet door-collar for my huge black cat who goes in and out often! He also sits in front of the door forcing it to stay open for quite a while--on battery power from the collar-- until he deems it to be the perfect moment to make his exit...cats be cats!

Works perfect

Replacement batteries are perfect. Great price for the quantity and battery life.

The batteries are extremely hard to access the packaging!!

Using the batteries for our pups to use their electronic door. The first battery to die lasts just over 4 months. It was at a not desirable time since the pup went out at 1:30 am to go potty and couldn’t get back in. Luckily the other pups alerted us to get their back in. From now one we will change batteries at the 4 month mark, unless it happens before.

just replaced my hi tech pet door battery with this one. Works absolutely great. Also, the sensor on the collar for the battery didn't work on my hi tech pet one, but works great on this one - bonus!!! And the price is much cheaper. I definitely recommend.
