High Tech Pet Collar Battery Hack - B3V1A vs CR2430 Batteries 

You say you don't need to keep the white plastic donut, and it works fine. I don't know how you did that, because without it, you would be connecting the positive and negative sides of the battery and it will short out. This will immediately drain the battery, get extremely hot and might even ignite. That's why they don't transport Li ion batteries in aircraft. KEEP THE WHITE DONUT! Then it works like you say. Thanks for the video; you are saving me a bundle!

Nice work. The original transmitters used a normal CR2430 battery. They later changed the design so it would require their special battery. I can only assume that was to generate revenue from battery sales, as the circuit boards hardly changed at all and they function exactly the same way. I don't have any of the forth-generation MS-4, but on my original (MS-1?) and MS-2 controllers, I stretch the spring around to the back side of the battery, put some heat shrink around the part of the spring that needs to be insulated away from the side of the battery, and drop in a CR2430. The best change I make is putting in a CR2450. The 5.0mm thick version of the battery lasts significantly longer, so I am not changing batteries nearly as often. Since a dead battery sometimes means cleaning the carpet, it is worth it. I'm sure stretching the spring voids the warranty, but I don't really care. No matter what battery I use, I put a zip tie around the transmitter to keep it closed. You can slide the zip tie off to the side when you want to open it.

The way this company manipulates the battery situation, forcing you to pay 10x for theirs and another 10x for "shipping," it would be less criminal if they just robbed me at gunpoint. Less offensive too.

Hey Mimi. Great video. I have had nothing but issues with these collars. I love this battery hack. I have had to order three of the water proof collars because each time the battery wears out and I try to open case the screw strips and then can't replace battery. If you put any kind of pressure on the case the plastic breaks. It has been so frustrating. And they raised the price of that collar by about $10. Very frustrating and you have to use the hi tec product for their door. The next video we need is how did you put the "key" on a regular dog collar. The one they provide is terrible and it would seem it's the only one you can use with the "key". Thanks for the good info on your video

Wow this is amazing. My first one took about ten minutes, now I can crank them out in about three! Thanks for the savings (we have three dogs and a cat, thats four batteries at a crack).

Thank you!!!! Just replaced it with what you showed!!!!

Update you can go on eBay and get 20 of them for $21 so essentially the same price as the cr32 batteries but you don't have to modify it

this may be a 7 yr old video...but sure came in handy tonight!!! Thank you.🐶

Worked like a charm! Thanks.

Really good video and explanation! You're correct the other gentleman used the washers to maintain pressure/connection. Your methods worked great for me. If a connection was loose a couple of layers of tape, or duct tape - on top of the other tape may help. Don't use duct tape directly on the battery! I am not poor but with 3 dogs the best price they offer on their batteries is too high, and I like to keep fresh batteries so none of our dogs end up locked out. Thank you!

Much better...your visuals definitely make it easier to follow.

Thank you for this video. I had watched DJ's and it was difficult to see. Thank you both!!! Subscribing to you both!

Not all heroes wear capes! thank you!!!

I just use the cr2430 and must put it in upside down because I dont modify anything and it works. life apprxo 3-4 months

I like Mimi you have a nice voice and your video really helped me and my dogs love you

Where did you get that little piece of fabric that holds the actual piece of the door opener to their collar?

Thank you so much! I find that I cannot release the tab welds on the bottom of the battery with an Exacto knife, so I use a small flathead screwdriver from a glasses repair kit. And the metallic tape (Shurtape) works perfectly to hold the tabs down. I really like Hitec Pets' products, but I am not a fan of these recurring costs for batteries. And in my experience, the collars only last a year or two before they fail and need replacing. And why can't they come up with a better way to attach the transmitting collar to my dogs' regular collars? My dogs and big and like to play rough, and that thin collar is just not tough enough. Oh well.

On the back of the transmitter you have a small loop of material with what looks to be a snap. Did you make that or where did you buy it? Thanks.

Thanks

Thanks for the video. Be careful with the Exacto knife! One slip and you can get cut badly!

Is the ms 5 compatible and if so is it a better device compared to the 4..great video btw

I would like to know where you got the collars seen in the video. I really would like to use my dogs regular collar.

how long last those original battery?

I’m trying to find something helpful for repairing these collars that stop working and it’s not the battery. I just can’t easily replace them anymore and have several that stopped working over the years. Why do they stop working? Anyone know?

I need a waterproof pouch for mine. The batteries only last a couple of days. I cant find a collar pouch. Any ideas?

I just replaced the battery in the collar and now the red test light won't go out. How do I fix it? I coudnt' find anything on High Tech. Thanks

How long did the manufacturer battery last and how long did the CR2430 battery last? If the manuf. battery lasts like 6 months, the hacking just is not worth it.

On our dog door, we have noticed that the door itself tends to want to not close all the way after she has used it the first time, and it keeps raising and lowering itself and wears out the battery. Any idea why this might be happening?

How long does a battery last long for you?

nice!

What kind of collar is that? What does it do?

You will want to use some Orange Goo to clean the sticky off of your xacto knife between batteries. Probably obvious when you ge to do another one- but I learned this doing my second one. (And you're probably going to need band aids! I know I did. :-)
