A:  This battery has those dimensions.

A:  The 21/23 battery has this size as shown in the two pictures. If your product calls for 21/23 then why worry about the dimensions? It should be fine for your application.

Answer This Question

A:  The battery is 6/16" inches in diameter. So if you measured it correctly this battery is too small. I would take your battery to Home Depot and get a staff person to help you get the correct battery.

by|Jul 27, 2021

A:  3/8" as shown in the picture.

The prices posted at Home Depot are not clear. I thought the batteries were $4.24 but in reality the two pack package was $8.48. The items need to state the price for the package and NOT for each battery.
