Lithium Battery Cold Charging

The zx900 rechargeable lithium ion battery performed well in cold temperatures. It is easily recharged with the included charging cable.

It works wonderfully charging the lithium battery included for my A6500.  Does exactly what it is supposed to do.  What else can you say.

This lithium battery is very reliable.

I needed to get basic power for lights into a shed that had no electrical hookup available. I have tried many battery powered lights, that just didn't cut it. They would die or were just not bright enough. I decided to try a Delta 2 and 2-100 watt solar panels to recharge the battery. I was only able to mount the panels on the east slope of the roof, but it has held the charge. I am in Ohio where it gets too cold and keeps the battery from charging when it gets too cold, so we have had several days where we weren't charging because the shed was too cold. I still have not run out of power for the 100' ten light strand I hung up. This setup is an expensive fix, but it has proved itself to work even through our cold, gray Ohio winter.

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.

I needed an extra charger to take with me on trips. I have the feeling this has some advanced technology for charging lithium batteries fast and safely. That may be why the price is high. There is no alternative product unless you can find a universal charger. ... I am pleased with the service and with the operation of the charger.
