Can you tell us if your Pronto M91 SureStep has gel batteries installed in it currently from the manufacturer? If that's the case, then yes, these batteries will be the correct replacement for you. If however you have AGM batteries, then you would need to replace it with an AGM set. If you're not sure and you can get to the part number on the batteries that you currently have, please send that information to us at orders@techbatterysolutions.com and we can make sure you get the correct batteries.
