Check that your collar is listed among the compatible models and that the existing battery carries part number 1157900 or 1157900-C. The physical dimensions and connector must match the original pack for a secure fit.

Questions about this item

How much power does the 7.2V 700mAh pack draw during a full day of training?

The pack stores 5.04Wh at 7.2V and 700mAh, so a full day's use depends on the collar's transmit duty cycle rather than a fixed draw from the battery itself.

What must I already own for this 1157900 replacement to work?

You need a Tri-Tronics collar from the Pro 200 XLS, Flyway Special XLS, Pro 100 XLS, Pro 500 XLS or Upland Special XLS series that originally used part 1157900 or 1157900-C.

Will the 50.9 x 31.75 x 21.6mm dimensions fit the battery compartment on my older Pro 100 XLS?

Yes, the pack is built to the original specifications for all listed models including the Pro 100 XLS, so the 50.9 x 31.75 x 21.6mm case matches the factory compartment.
