Great product, Sony will not lead you wrong.
Lisa Christiana
The Sony Power charger is excellent because I can charge any number of batteries up to 4 at a time.

This was a decent investment but well worth the money I will be saving in batteries!

When it comes to battery chargers, the word 'Value' typically means 'cheaply-made junk'. I have previously examined many so-called value chargers from major battery manufacturers (including Duracell CEF14, Rayovac PS131, Energizer CHVCMWB, Sanyo MQN06, etc.), only to be disappointed by all of them. Those chargers all share a common problem: they can only charge in pairs. That means you are out of luck if you have appliances that require 1 or 3 cells. Charging in pairs may also lead to over-charging, which is bad for battery lifespan. So although those chargrs are cheaper to buy, they end up wasting you more money in the long run.

The charger in this package (Sony Cycle Energy BCG34HLD4KN Power Charger with 4 Pre-Charged 2000 mAh AA Batteries), on the other hand, is actually a decent product. It has 4 independent charging channels, which allow you to charge 1-4 AA or AAA cells. During charging, the voltage profile of each cell is monitored. Charging stops as soon as each cell is fully charged - although the indicator light only goes out when ALL cells are done.

The average charging current is 360mA for each AA cell (actually 1.44A pulsed at 25% duty cycle), 140mA for AAA cell.

I wanted a small and cheap charger that had 4 independent charging circuits. Almost all of the inexpensive chargers on the market can only charge batteries in matched pairs. If you have an odd number of batteries or a pair that are discharged to a different amount, they will not charge property. But this charger can handle any number batteries in any condition. I verified this myself when the product arrived.

Another positive thing about this charger is that it is very small and light. I can't imagine one getting any smaller. It accepts any sort of wall outlet voltage and the outlet prongs fold down for compact storage. So it is a great travel companion.

The biggest drawback of the charger is that it has only one indicator light. So the charger cannot tell you if some (but not all) of the batteries are charged or if one of the batteries is bad. In practice, the biggest drawback of that is that if you load in a mixed batch of batteries, some mostly charged and some mostly discharged, they all need to stay in until the last battery is done. Some of the bigger and more expensive chargers have four lights or even four little graphs to tell you the state of each battery. That is very nice but probably would have added to the size and cost of the charger, so I can't complain too much.

As to the batteries, I have only had the product for a month so I cannot say much. The batteries all worked out of the box and appear to hold a charge well. Their voltage and charging characteristics are very similar to Sanyo Eneloops I own (my favorite battery). I have seen some people claim the Sony batteries are in fact re-packaged Eneloops. If they are, or at least behave the same over the long-term, that would make this package an amazingly good deal.

Got these and love them. They work when I want them too and don't lose
a charge sitting on a shelf like regular re-charables.
Really great for a flash that you use intermittently, but need it to work
when you're in the field. Theses hold a charge very well in camera as well.

I thought that the fact that the cells were monitored independently was enough to satisfy my requirements. The problem is that if the LED blinks, it means some number of the cells are no longer working correctly. But you don't know how many or which one(s) are bad. The only way to figure it out is to then charge each one separately -- many, many hours. My previous Lenmar charger had independent LEDs, but it failed abruptly after relatively little use. It had never identified any of my stock of batteries as being "bad", but the new Sony charger claims they are nearly all bad. I will assume its assessment is correct, but it took forever to check them all one at a time. Bottom line is that although it is great that you can charge any number (1-4) cells at a time, unless you have an LED for each cell, you are at a big disadvantage if any fail.

I didn't really need the batteries that come with this. My understanding is that if they are white topped, they are Sanyo Eneloops that have been rebranded and if they're black tops they are the very similar Rayovac rebranded batteries. I got white tops. The batteries in either case are fine. I have plenty of each and they do the job.

What I needed was a cheap charger that will charge batteries one at a time if need be. This charger will do that. It also seems to keep the batteries nice and cool which is important to long life of batteries. I could have bought a charger by itself that has even more features for thirty bucks or so, but this does all I need a charger to do and came with batteries I will eventually make use of for a better price. That's a great buy if you ask me
