Not worth the extra money

Poor performance, died faster than the alkaline batteries I used in the same application.

Great beat deal I can find and free shipping

These batteries are too expensive. This is the reason for the 4 star rating.

Best batteries we have found for an insulin pump (T1D).

Great value, will buy again

Received it fast when ordered

seem to be working well. easier to obtain than a drive to Indy

Excellent in cold temps and has a long shelf life

AA Batteries are always needed. Not much to say, there just batteries.
