RAYOVAC D 8-Pack FUSION Premium Alkaline Batteries, 813-8LTFUSK

Duran bastante

Some were dead out of the package. Others did not last. DO NOT BUY!

I just put in these brand new batteries, received a day ago, and they barely made any difference in the flashlight with batteries that had been in there for 4 years. The flashlight was for emergencies so it was a shelf-life drain on the batteries. I don't know if these are duds, or if they were replaced in the package (because I found the package had been sliced open a couple of inches on one side. I'll see how their customer support handles this issue.

Used these for my field radio. They last longer than energizers, but they die faster when they go, by a small margin. They have good run time and have better construction, according to leak safety tests I have read. All in all a great battery with a cool red top. Not being made in China is a plus these days as well, supporting North American industry is good for all of us. I will buy these D cells from now on and I go through quite a few in a year. Good job Rayovac! I never thought I would switch from Energizer. Oh ya and the voltage was a tad higher on the ray o vacs. Don't be scared to try these, you won't regret it. Rayovac finally has a superior battery.

In the past I steered away from this brand however I tried them again as this is newer technology and well we are amazed. They last long, I can't say the exact same as let's say Duracell but I believe they would be neck to neck in a race. I recommend these batteries and save a few dollars
