Duracell MN9100/E90/LR1 Medical Battery 1.5 V Card 2 Size N - 2 Count, 2 Pack - 4 Batteries Total,2 Count (Pack of 2)

These batteries worked perfectly. I was having trouble finding them anywhere else.

Perfect fit for my vintage HP19B2 calculator. Last replacement lasted 8 years.

Works as expected of Duracell. No issues. Lasts for about two years with reasonable usage (1-2 hours/mo).

Good

This double pack of Duracell N batteries is an economical way to keep my vanity clock running perfectly. Definitely recommend.

The estimated shelf life of alkaline batteries, according to the interwebs, is about 10 years.The batteries I received are dated best before March 2027 so they've been sitting around for about 6.5 years. That may be why this seemed like a good deal at $7.99 for 4 batteries.The expiration is just an estimate and not at all a concern if you're using them immediately. The batteries work just fine in my old HP-28S, but don't buy more than you need.

My son received a pocket watch that required this type of battery. Couldn't find it at the store. Quick delivery and no issues.
