I think it is the best green action I can take when using AA batteries on a regular basis.

The batteries will not hold a charge - maybe 2 to 3 hours without being used.

This set includes 4 AA cells Made in Japan for Sony by Sanyo, as well as a timed charger, NOT a smart charger as its similar looking Sony variants.
The Sony Power Charger can recharge 4 AAA or AA cells at a time. Unlike the Panasonic BQ-390 which I also used and reviewed, this Sony uses a timer to stop charging. The Panasonic BQ-390 has advanced circuitry inside to monitor charging through temperature, voltage drop, and the cell's internal resistance, so that you'll get more precise charging and less damage from overcharging of simpler chargers. Sony also offers a similarly advanced product, but this model is a cheaper timed model. It charges the 2100mAH cells for 8 hours straight, or 800 mAh AAA cells for 7 hours straight. If you charge a partially used cell, it will not detect when the cell reaches full charge, and might overcharge. It's best to charge a fully depleted cell with timed chargers.

This is a timed charger, but well matched to the supplied 2100mAh NiMH batteries. The manual recommends charging after a full discharge, so it may overcharge your partially depleted cell or an older cell with lower capacity. As long as you recharge a fully empty, ~2100mAh cell, it shall be fine.
The included cells, actually made by Sanyo-GE, are premium cells, and only surpassed by Sanyo's latest 2300mAh cells.

This was the best deal I found on rechargable NiHM batteries and that too these are made in Japan by Sony. It has a capacity of 2300mAh.

There is one problem with this. This charger does not automatically shut off when the batteries finish charging. So the first time I charged them, I kept waiting for the indicator to go off and I realized after 18 hrs that they are not going to go off.

So, though the batteries are good the charger is not. I would suggest people to go with another sony rechargable model that sells here for just a few dollars more.

SONY has updated this package ("Sony Cycle Energy Power Charger with 4 2500 mAh AA Batteries") recently. It now looks quite different from what was once shown on the Amazon product description page. For example, the old charger is silver in color, while the new charger is white. But beside colors, they looked almost identical, and even share the same model number (BCG34HLD). So is this really a new and improved model, or just a simple cosmetic update?

According to all the older Amazon spotlight reviews, the old model is a timer-based dumb charger. I'm happy to report that this is no longer the case. The new model is actually a 'smart' charger, meaning that it monitors each battery's voltage independently during charging, and stops when each cell is fully charged. In fact, it is very nicely designed for such a value-priced charger. Here are some things I like about this charger:

+ Charges 1-4 AA/AAA cells individually - no need to charge in pairs
+ Compact, one-piece design with fold-down AC plugs - no need for power cords or wall adapters.
+ Low-profile (just 1.1" thick) so it fits in camera bags easily.
+ Accepts 100-240V universal voltage.
+ Bad cell detection - indicator light flashes in case the resistance is too high (alkaline cell).

The average charging current is 360mA for each AA cell (actually 1.44A pulsed at 25% duty cycle), 140mA for AAA cell. That means it takes about 7-8 hours to fully recharge 2500mAh AA cells.

The included four SONY AA batteries, however, appear to be just the same old 2500mAh cells with a new shiny wrapper.

These 2100mah Sony AA batteries and charger are the best I own. I have many different brands, Energizer, Kodak, Panasonic etc. and probably a 1/2 dozen chargers.
As some may or may not know batteries that are "trickle or slow" charged will last a good bit longer. This charger takes about 6-7 hours before the full indicator light goes off. On quick charger 15-60 min ones they still fair well but of course not as nearly as long as slow charges.
If you have a digital camera and are using disposable batteries this is a necessary cost saving purchase. So often in Camera reviews people complain "It eats batteries" It is best to have 2 to 3 extra sets and a set runs down - who cares! Throw them in the charger and switch sets.

This kit is exactly what I needed to keep my wife from throwing her camera in the junk drawer for good. The camera's flash would burn through the alkalines at a rediculous rate, and these Ni-MH power through hundreds of shots with ease. I'm really impressed - especially at the price.

I have had the same batteries in my digital camera for over a week now. I have taken about 70 pictures, played around with my new digital camera, transferred images to my PC and the batteries are still going. I went through two regular AA batteries in a few hours before I got this. I would highly recommend this product.

The BCG-34HLD works fine, though the charger's 360mAH output rate means it'll take a about 6 hours to charge the 2100mAH batteries. I bought it because it had a decent amount of charge to it, and hey it's comparatively cheap, but now I wish I had bought one with a charger that would accept a 12V lighter connection so that I could hook it up to a 5V solar panel. At sundancesolar, they sell a kit with 2500mAH batteries and charger that has a lighter connection so you can use a solar panel. At a 800mAH rate, 2500mAH batteries will only take about 3 hours to recharge and you don't have to be plugged into the grid! I'll probably use these Sony batteries in a new solar charger.

A few things to be aware of with NiMH batteries:

*If NiMH batteries are repeatedly partially discharged and then recharged, it is necessary to do an occasional complete discharge followed by a complete recharge. However, more often overcharging is the cause of voltage depression, so for this charger, you must keep track of how many hours the batteries have been charging (5 hours, 50 minutes).

*NiMH batteries self discharge about 1-3% per day, so they should be charged when you'll be needing them. This makes them a bad choice for emergency equipment that is stored away for long periods. They should also not be used in equipment that continues to drain them after they've been discharged as this can render them unusable.

*Alkaline batteries start at 1.5 volts and gradually drop to less than 1.0 volts. NiMH batteries remain at a 1.2 volt average for about 80% of their discharge cycle.
