Alkaline Or Silver Oxide Watch Battery

Nikon specified either an Alkaline or Silver Oxide battery for my original model Nikkormat EL. I tried both and both work perfectly. So this is a good option for you in one of these older cameras. I can't say about all cameras, but my Nikkormat's meter works just as well with this silver oxide battery as it does with the alkaline. Supposedly, sliver oxide batteries work better at colder temperatures. So give it a try!

Whereas the voltage output of alkaline batteries has been shown to decrease over use and time, silver oxide batteries have a much more constant voltage output over the life of the battery. For this reason I prefer to use silver oxide batteries whenever possible. I chose the Exell S28PX battery to use in my Pentax digital spotmeter, which I've used periodically from time to time over the past two years, including in cold winter weather, and I've been very satisfied with its performance.

My old cameras seem happier with silver oxide than with alkaline batteries. The silver oxide ones keep their voltage stable longer, and they have less of a tendency to leak than alkaline batteries. They are harder to find these days, so I'm glad that B&H still stocks them.

I chose to buy a silver oxide battery to use in my Pentax digital spotmeter because silver oxide batteries are supposed to maintain a constant voltage output throughout their life and thus provide consistent performance, whereas the voltage output of alkaline batteries declines over time and thus affects their performance. The Excel S28PX battery that I bought seems to be performing well after about 2 years of occasional use; I'm happy with it.

This battery allows accurate metering on my Minolta SRT MCII. Alkaline or Silver Oxide batteries do not supply the correct voltage for accurate metering as the camera was designed to use mercury batteries which are no longer manufactured for environmental reasons. There are few other options (modifications to the camera meter circuit or expensive compensated adaptors) so this is my go-to solution.

The charge lasts a lot, but when used in flash, I'm surprised it does not discharge as fast as an alkaline battery.

Much better than alkaline batteries!

I bought a several of these C cell alkaline battery packages to donate to the Hurricane Harvey relief/recovery effort. I know from past experience that RAYOVAC batteries are reliable, and the re-sealable packaging should make them less susceptible to environmental exposure; although I don't think they'll remain in the packaging very long. The quantity packaging is also easier to ship than individual batteries or battery pairs. Looks like I might have to get more, to send to some of the other disaster sites.

Solid Light - good to keep in my truck. I like the Dual Power. I keep the rechargeable in the light but keep the alkaline battery pack handy so I can use the light while I recharge the battery outside of the light. Nice and bright.

Bought the flashlight and this battery as an option. Saves money over the long haul and keeps alkaline batteries out of the landfill. Quick recharge, excellent output.
