    • I am in need of a new battery. I bought my Compex in Italy. I have the Compex Theta Stim model. Will this be the right battery for this one? If not which one?

    • Yes, the CompexThetaStim uses same battery pack as US CompexSport or FitnessTrainer

    • I too bought my Compex Sport in Italy in 2006 and need a replacement battery pack. Please advice if this item is compatible with my device (it's the square blue one). Thanks
    • Hello, Leo -

      If you are referring to either the Fitness II, SportElite, or Performance EU (all 3 of those units are blue), yes the replacement battery pack can be used.

      If you have further questions, please feel free to contact our product support specialists at 888-405-3251.

      Thank you and have a great day!

    • Hallo, I own a old Compex device bought in Italy years ago and I need to replace the battery pack. The model is Compex Medi-Compex and I would like to know if this battery pack is compatible with my divice. Thank you.
    • Hello, Alex -

      Because your unit was purchased in Italy, they are not compatible with the American batteries. You would have to contact the person in charge of Italy (where unit was purchased):

      Thank you and have a wonderful day!

    • Hi is this battery pack compatible with the Compex Sport 400 bought in the UK?
    • Hello, Baris -

      No, the battery packs are not interchangeable for other international units.

      Thank you and have a wonderful day!

    • We have an older model, probably one of the first and need a battery. I believe it is called a sport. Do you still have a battery that would fit this model?

    • Hello Greg,

      Yes, we offer replacement battery packs. Please see the link below.

      thanks for Contacting Donjoy.

    • Hi, I bought a Compex in 2004 in Spain. The model is Mi-Sport500 and I have to replace the battery. Which one is the battery I should buy? Thanks
    • Because you have a European model we can't be certain that the batterys that we carry will work. Youcan try the battery that looks like the battery that is in your unit
