Ensure your high-drain electronic devices have power when you need it with this Sony 4-pack of AA rechargeable batteries and included charger.
Whether at home or on the road, this four-pack of AA rechargeable batteries and portable power charger are ideal for keeping your high-capacity electronic devices such as digital cameras and handheld gaming systems charged and ready for use. A great alternative to disposables, Sony 2500mAh rechargeable batteries last up to five times longer than standard alkaline batteries. The supplied charger features worldwide voltage compatibility, flip down plug, automatic charge cut-off timer, alkaline battery detection and charges up to four AA or AAA batteries. Additionally, the four included AA Nickel-Metal Hydride (NiMH) batteries can be recharged up to 300 times.
Get the power you need quickly with a 7 hour charge time. The included charger can charge up to 4 AA/AAA Cycle Energy rechargeable batteries at a time.
Enjoy recharging with peace of mind with automatic safety features built into the Sony battery charger. Voltage monitoring and a safety timer along with temperature monitoring keep your batteries from overcharging or overheating, potentially causing a fire or electronics damage. Alkaline battery detection ensures you're charging the right kind of battery, without damaging the battery or the charger.
This Sony charger comes with four AA 2,500 mAh Cycle Energy NiMH rechargeable batteries that, when fully charged, last 5x longer than alkaline batteries. They're rechargeable up to 300x, so you've got long-lasting power when you need it.
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.
The included cells, actually made by Sanyo-GE, are premium cells, and only surpassed by Sanyo's latest 2300mAh cells.
