  1 Question
Q: Question : Are 40volt 2ah batteries interchangeable with 40 volt 4ah Batteries ? You told me before that 4ah batteries give a longer running time. If my Leaf blower comes with a 40volt 2ah would it be harmful to run the 40v 4ah battery in it ? Thank you Sir.

by Timothy H. Ellis from New Jersey on December 03, 2013

A: Timothy,

There is no harm done using a 2AH or 4AH battery in any of the tools. You do have to make sure that the brand, model and voltage do match or you most definitely run into problems.

You can find the exact match for your tool by clicking on the accessories button on that tools respective product page.

If you have any further questions, always feel free to contact me directly at 800-710-7499 Ext. 133.

I'm always happy to help!
