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.

I ordered this product a week ago and it's still not have been shipped; despite the "ships in 24 hours" expression.

The other items in the same order were delivered days ago, but Sony Power Charger is still waiting for shipment...

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.
