Sony Power Battery Charger with 4 AA Ni-MH Rechargeable Batteries

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.

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.


Great batteries & Charger   June 25, 2004

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.


Charging time   May 27, 2004

I bought this without knowing what the charging time was. I took a risk since it was at an affordable price and found out to my dismay that the charging time is as follows:

1-4 batteries:

2100mAh Approx 7 hours
1700mAh Approx 6 hours
800mAh Approx 7 hours
700mAh Approx 6 hours

I haven't used the product yet...I just got it today. I don't know. I might return it for the Kodak 1 hour charger one for the same price (18.99) but the deal is gone for this product, it's back to 19.99. Anyways...pretty fast shipping though =)
