I Drain Watch Batteries

I have several 3rd party batteries and they drain way faster than the Sony. I will only use these batteries going forward.

take a bit of calibrating - it reaches further and less drain on flash batteries.

This one lasts longer than the one that came with the Z7. We know how mirrorless cameras drain the life out of batteries, so the longer one lasts, the better.

The drain battery feature is brilliant. It helps maximize the life of your batteries.

I like the separate meters for each battery and drain option to get the batteries back to full charge.

Very easy to setup. Love the modular design of AT system components. It does seem to drain batteries faster but I purchased Eneloop Pros to make sure I was covered for my events.

Love the brightness of this little panel, and very pleasant with the soft box, but if intended to be used with batteries, 50% or more, the batteries will drain in less than 15 minutes.

I bought this once it was released and really like it so far. My only issue is it seems to drain the batteries fairly quickly. I have a Link Evo that I bought in 2015 and set the setting to the same as the flex. I used the exact same energizer lithium batteries and the evo out performs the battery life by a long shot.

I've never had a battery charger that would actually drain the batteries completely before charging them. That's a really good idea for NiMH, since they are supposed to be empty, but their usefulness drops off before they are dead, if you're using them for flash. The display is bright, and always on unless you unplug it, which is what I do. It comes with a car adapter. Excellent investment, very happy that I went with this particular charger, so I could have two sets of batteries at all times. Batteries also charge up quickly, about 4 hours as advertised, with a complete drainage.

This is the most powerful Camera Battery I've ever seen. Still going strong after extended use that would drain lesser Batteries. Charges in 4 hrs. or less & connects quickly to my D850 in the MB-D18 grip. Worth the investment.
