volt yukon 750

Jim britt

Hello everyone, my friend bought a volt Yukon 750 with a dorado retention 16 ah battery,4 or 5 years ago and it's time for a new one, volt has a 17.5ah battery, my question is, will this battery fit in the old cradle because he still has some juice left in the old battery and would like to use the old one as a backup or for really long rides, Thankyou,any feedback would be appreciated.
