Our experience with battery stuff was very good. The reps we spoke with were knowledgeable, courteous, and professional. Questions were answered in a timely fashion.
The product is performing as expected for the week we have had the two batteries. We did have to call to find out the manufacture date which should be stamped on the battery instead of a code that the consumer cannot understand. We still don’t know the date but were able to find out they were made at the same time. Would be helpful to know they are fresh batteries or old stock.
