Do Most Watch Batteries Contain Mercury

This is a great replacement for the old mercury batteries used in my Olympus OM-1.

good product. works well. you need it to replace the old mercury batteries.

Great replacement for old light meter mercury batteries

Most of the batteries recharge in about an hour.

Very satisfied. As described and do properly the job. The replacement for 1.35 V mercury batteries

Do you need it? I don't know. Do you want it? Most definitely!! I was hesitant before pulling the trigger on this. I considered how lazy you'd have to be to not want to screw you tripod head onto tripod legs but in the same breath, a wise person once said "buy once, cry once" You'll wonder how you've worked without this. Comes well packaged and tools included :)

This is a niche product. Most buyers won't need 10Gbps or 90W. The EnGenius 90W 10GbE PoE Adapter is Super Fast, Powerful, Small and Well Built! It does the job better than anything else at this price point. Do I need anything faster? Do I need anything more powerful? Not yet! What will you use it for? I recommend this product for select wireless access points, WISP modems, and outdoor antennas (Microwave or 5G mmWave).

Works as a replacement for older mercury style batteries, although I’ve read that camera meters using alkaline batteries can be a little unreliable especially in brighter conditions.

Even though these batteries are 1.5V and the original mercury-oxide batteries were 1.4V, I really detect no difference the the meter output, and given the latitude of film, would make no practical difference. They work great!

B&H had the odd replacement for obsolete mercury batteries that allowed me to test the light meter in an early 1970s Leica CL. Perfect replacement and it works!
