We had five batteries in this pack that were dead straight out of the package. The purchase date was six months before we tried to use them.

I'm disappointed that they work for 48 hours on my Blink doorbell.......i don't understand how these are any better than regular batteries.

I thought Energizer batteries are supposed to be the best. NOT! They do NOT last as long as other brands.

Don’t waste your money! I bought these to use in outdoor Christmas lights….they didn’t last any longer than the non-ultimate version.

Batteries are good and they don’t leak although they are expensive and when they die they die all at once.

Batteries were best price around but found they were old and didn’t last a week in my game camera. Waste of money.

These gems last sooo long! They measure up to a shade over 1.7 volts. I dont use any other battery.

Seems like everything on the ranch runs on batteries - flashlights, deer feeders, trail cameras, radios, etc. We purchase these several time a year.

I use the Energizer Ultimate Lithium AA batteries in my trail cameras. Gives longer lasting, dependable power.

We are diabetics and insulin pumps only use this type of battery. The cost has increased over time. This purchase price caused sticker shock!
