Cordless Hand Vacuum Lithium Battery

This lithium battery is very reliable.

The long life AA lithium battery has many uses including in an emergency so keeping spares on-hand isn't a worry due to the 10 year shelf life. I use it in business & personal life for cameras, NOAA weather radio, flashlights, hand-held computer, emergency strobe light, laser level, to name a few. B&H always has fresh inventory

It's good to have a battery testing on hand and this one does the lithium and alkaline batteries. One thing I would note is for rechargeable batteries that have been handled a lot; it a good practice to clean terminals with  isopropyl alcohol otherwise it could give inconsistent results. This is covered in the manual and in their FAQ on the website. It is not readily apparent as to why you would need to read the manual for such a straight forward device :).

i use these battery's in my cordless phone I only need to charge my phone once a week and that's it you cant ask for more than that

I own a few cordless lavalier & hand-held microphone systems (by Sennheiser) that are used for my audio/video projects. An antenna to one of the cordless receivers was found to be broken after I put it in my made-for-video equipment backpack. So, I did a quick research for a safer way to transport the Sennheiser ENG systems and found this on the B&H web-site. Bottom line is that the entire unit of each cordless transformer & receiver, including the antenna, is safely packed into the case for transport.

This manual flash has everything I need and especially like the lithium battery. just bought a second unit.

Long lasting Lithium battery makes it cost effective.

Lithium without the need to recharge. Excellent long-life battery.

I bought one, have to buy another, great sony lithium battery.

The Watson Lithium Battery is a great backup for a Nikon battery. It lasts as long and makes a great back up for a Nikon battery.
