The 4-Hour Rapid Charger for AA and AAA NiMH and NiCd Rechargeable Batteries from Watson charges 2 or 4 AA or AAA batteries (not included). It is compatible with both NiMH and NiCd batteries. Charging time varies from 100-280 min, depending upon battery quantity, size, and capacity.

The charger's intelligent Negative Delta-V microprocessor doles out the full charge to each battery, while Zero Slope Detection prevents overcharging. The Safety Guard Timer automatically shuts off after 6 hr in cases where batteries are taking far longer than normal to charge, in order to prevent damage from excessive current.

The charger has two charging level indicator lights to keep you apprised of battery status. Switching 100-240VAC input power enables use all over the world. The charger's compact outlet prongs can fold in, making the unit more compact for storage.

Will charge either 2 or 4 AA or AAA batteries (sold separately)
Works with batteries that have Nickel-Metal Hydride (NiMH) or Nickel-Cadmium (NiCd) chemistry
Charging time varies based upon battery quantity, size, and capacity. Charging 2 AAA batteries will take about 100 min, while 4 AAA's will require about 200 min.

An intelligent Negative Delta-V microprocessor ensures that each battery is charged to its full capacity, while the Zero Slope Detection feature prevents overcharging
Safety Guard Timer will automatically shut off after 6 hr. This makes sure that, in cases where batteries are taking far longer than normal to charge, they will not be exposed to excessive current that could cause damage

      WARNING!! this is a charger that works like a charm, just don't pay attention to the charging directions.

      Here's the scoop: When you start charging the batteries the 2 LCD red lights will blink and instantly will stop doing it, but it doesn't mean the charger is not doing it's job, is just that the lit red lights will stay on 'till the batteries are completely charged and then the LCD lights will turn green.

      It's a matter of typo error on PEARSTONE part but the chargers work just fine, I should know I bought 2 from B&H

      Seems to charge my NiMH batteries quickly as promised but the charge indicator LED's are unreliable. They are suppose to flash during charging and remain lit when charging is done while keeping the batteries trickle charged. However, I insert nearly completely dead NiMH rechargables and the LED's flash for a couple seconds then remain lit but the batteries are not charged. If I leave the batteries in the charger they do get charged in about four hours but I can only tell by feeling them get hot during charging and then cooling when charging is complete. I have tried the charger with several brands of NiMH batteries and the results are the same. This charger is value priced but I would have gladly paid more for better reliability but options are limited.

          I have some devices that use AA & AAA NiMH & NiCd batteries, a DISH remote, and my "land-line" phones.
          The charger is small & compact, and easy to use. The instructions were not quite clear on how to install AAA batteries to recharge, but it only took me a minute to figure it out.

            Nothing to understand. Insert the batteries, plug the charger into the wall, and forget about it. When the lights turn green the batteries are charged. Couldn't be easier. I'll never buy "real" betteries again!

                Use to charge AAs for flash units both at home and on the road.
                What's great about it: Universal voltage and folding plug makes for easier transport and usage in other countries with different voltages. Is light weight.
                What's not so great about it: Haven't used it that long so don't know how long it will last.

                    I use this charger to charge up my Sanyo XX Powered by Eneloop 'AA' Batteries. Unlike my old Enloop charger, this one doesn't insist on only charging when all four battery bays are occupied.

                    This one charges when you insert a pair of batteries and also give the amount of charge and charges incredibly fast. Great charger.

                                Great construction, and works wonderfully to charge AA batteries for my job (wedding photography). Construction is simple and very well-made for it's use. It's not bulletproof.. but really, who needs anything more than a simple charger that does the job?

                                      I needed a charger that handled both AA and AAA batteries. This one works with either.

                                        WARNING!! this is a charger that works like a charm, just don't pay attention to the charging directions.

                                        Here's the scoop: When you start charging the batteries the 2 LCD red lights will blink and instantly will stop doing it, but it doesn't mean the charger is not doing it's job, is just that the lit red lights will stay on 'till the batteries are completely charged and then the LCD lights will turn green.

                                        It's a matter of typo error on PEARSTONE part but the chargers work just fine, I should know I bought 2 from B&H

                                        I bought this to charge the batteries I use for my macro lens flash. It works great, and its easy to use. From empty to full in less than 4 hrs. Only drawback is that its not a quicker charge.
