2Nd Amendment Pocket Watch Battery Size

This is a back-up (2nd battery) for my pocket camera (Olympus Stylus 770 SW) that I take everywhere and it takes the abuse (shock, water, mud, cold, etc.). I originally purchased an off Brand ... (cheaper) and It worked OK for awhile, but the original OEM battery is still going strong and the off Brand died (actually it lost charge quickly for some time before completely giving up the ghost). So now I purchased an OEM replacement and if this one works as well as the first OEM one, then I may not have to buy another battery for this camera for a long time.

I carry this light in my watch pocket. It is a great performer. I love it. It is handy. Always on me ready to go. The battery really lasts. I haven't logged the hours, but it seems to me the battery actually lasts longer than it is rated. One caveat: While it may be weather resistant, it does not withstand the wash and rinse cycle of a washing machine. You must remember to remove it from the watch pocket before washing your trousers. Going through the wash cycle has a deleterious effect on performance.

2nd battery for my camera

Use as 2nd battery on an S5, no issues.

No surprises here. I'm glad to have the 2nd battery.

Nice 2nd battery for my A7R4

Small size fits in my pocket. Long lasting battery. Pure white light with 3 intensity levels. I use it mostly with my Canon G16 and iPhone 11 Pro. The silicon diffuser is great. It's waterproof so I take it anywhere. I recommend getting a small gorilla pod for additional flexibility.

This flashlight has three advantages: the small size, the rechargeable battery, and the (unbelievably) bright white light! I use this flashlight every night while walking my dog and it is perfect for lighting up both streets and skunks. The only drawback is that you need to remove the battery to charge it, but that's also kind of cool, especially if you have a couple of devices that use this battery type. In that case, it would be an advantage. The thing I love the most is that the flashlight is so small (about 5 inches long) and fits in my pocket and my hand very comfortably. Bigger flashlights become a burden because they can't be stowed in a pocket and must be carried in the hand. I also love the pure white light from this flashlight; it's easy to focus, but also makes a great floodlight. I'm happy with my choice.

Love that I now have a back-up battery to this older small Panasonic Lumix that fits in my pocket. I love the size and the ease for grabbing a shot here and there. And now I can not worry about it becoming extinct. Thank you!
