Are Wireless Chargers Bad For Battery

Between battery grips, strobes, and wireless triggers I need to charge dozens of AA batteries for a shoot. I bought three of these, and now can pop in two dozen at a time, walk away, and know that the chargers will individually top off each battery and then turn off. I've used faster chargers, but am not happy with how hot they make the cells. These still make the cells warm, but at a level I'm comfortable with. This takes charging to a new level of sophistication and convenience.

Battery chargers, what can you say? This one works and doesn't take a week to charge the battery.

Works great with dual battery chargers.

There is not a thing I can say bad about this wireless remote. works great.

I've never had a bad Sony battery.

I’ve only used the batteries and chargers twice so far but they work as advertised on my wireless HDMI unit.

Just right for extending wireless phone chargers in desk to available power source.

I purchased this charger to charge some high capacity batteries that I use for my flash and vertical grip after I found the one I was using would not charge them fully. The best feature is how it charges each battery independently and shows you the status of each cell as well. I also found that I had a couple of batteries that where no good with this charger. Part of the problem with the previous chargers where these bad cells and the lack of ability to identify them. The old charger would simpley indicate everything was charged whereas this unit kept charging the good batteries while identifying the bad one. This is not a super fast charger however I do not see that as an issue sine it does such a great job of FULLY charging your batteries unlike other chargers. You can also use this charger to discharge cells as you see fit. I highly recommend this charger!

I purchased this to replace the one I left at a hotel. In the past I have purchased generic chargers and generic batteries but the outcome had always been bad. So you do get what you pay for. So while you can save a few dollars with a generic charger, the damage it can possibly do to your $80 Nikon batteries!

I have three of these and although I had one go bad, something in wireless communications just randomly craps out, still can't beat these for the price.
