SportDOG SDT00-11907 SD-400 & SD-800 Series Receiver Battery Kit

This is also the replacement for the Yardtrainer 350. Customer service told me that it would not work. But, I talked directly with Sportdog and they gave me the item number for the proper replacement and it is also the 11907. If you look at Sportdog's website, it will tell you that this is the proper replacement for the SD350. I just received it, and installed it. The batteries are identical in size, power, and appearance.

So glad I purchased. After over four years of moderate to frequent use my batteries finally bit it. I knew they were almost completely dead but I still hadn’t realized just how quiet the beeps had gotten or how great it would be to have so many hours back on battery life until I finally got both kits and replaced the batteries. (It’s gradual so I got used to it working for shorter and shorter periods, quieter and quieter beeps.) Now the system is back up and running good as new! Gives me and my dog more freedom to enjoy the great outdoors just like when the system was first purchased. And the replacement gasket is much appreciated for us water-sport fanatics. Plus the deal on Chewy couldn’t be So glad I purchased. After over four years of moderate to frequent use my batteries finally bit it.

Now they just need to stock the transmitter and receiver replacements so people aren’t ordering each piece from a different company. … more

The battery installed OK but worked for less than 6 weeks.

Could have found replacements cheaper, but didn’t want to hassle of misfit poor quality etc. .I would go this route next time

Battery took almost week and half to arrive. Much longer than any other chewy order that has only taken max 3 days. All said and done worked like a champ.

Battery fit perfectly and was easy to change. Did not have to purchase a new collar. Glad that it was still available.

Fast shipping,just as described, fits perfectly, works perfectly.

Works as intended. Arrived within stated time and easy to install.

Replacing the battery in these units is a little bit of a pain. Since they are designed to be used in all outdoor conditions, there is a gasket where the cover meets the unit. They give you an new gasket just in case the old one is deteriorated or damaged during the opening. Good product.

We purchased this for training collar that was given to us. The battery either isn’t the proper one for our remote or the battery doesn’t hold a charge of the charger.
