Product Highlights
  • For 1-8 AA / AAA NiMH or NiCd Batteries
  • Charging Time: 1.6-4.6 hr
  • Delta-V Microprocessor for Full Charging
  • Discharging to Refresh Batteries
  • 8 LCD Charging Indicators
  • AC Adapter: 100-240V for Worldwide Use
  • DC Adapter for Car Charging

The Watson 8-Bay Rapid Charger for AA / AAA NiMH or NiCd Rechargeable Batteries charges up to 8 AA or AAA size nickel-metal hydride or nickel-cadmium rechargeable batteries. Charging time ranges from 3.6-4.6 hr for AA batteries, and 1.6-2 hr for AAA's. Eight individual LCD indicators give the charging status for each battery. Patented technology permits the charging of different sizes and types of battery simultaneously--charge a AA with a AAA, or an NiMH with an NiCd.

The charger's intelligent microprocessor doles out the full charge to each battery while preventing overcharging, thanks to Delta Voltage Protection. The Safety Timer with Automatic Timer Shut-Off senses when batteries are fully charged and ceases charging. Automatic Charge Current Selection automatically chooses the optimal current for the batteries you're charging. Reverse Polarity Protection and Alkaline and Bad Battery Protection safeguard the charger and your batteries against damage when batteries are installed improperly. There's also a discharge function, allowing you to refresh the batteries prior to charging.

The charger features an icon that shifts up and down during discharging, and stops shifting when discharge is complete. This icon also displays battery capacity while charging. The full-battery icon lights up when the batteries are fully charged. A flashing full-battery icon indicates an abnormality, such as the presence of a bad or alkaline battery, and at this point the charger will cease its operation. The charger is powered by an included external AC adapter with switching 100-240V power for worldwide use, or by an optional 12-24V DC cord (not included) which can plug into your car's cigarette lighter for charging on-the-go.

    I shoot 50-60 Weddings a year and countless other assignments. I use rechargeable AA batteries in 4 different flash units along with some external battery packs. After a several disappointing experiences with Rapid 30 minute or 1 hour chargers (which tend to short a battery as often as charge it) I made the move to this 8 bay trickle charger. The slow steady charge and 8 independent bays with independent readings allow me to charge batteries confidently, knowing when they're full and not shorted. You can also dump the power in a battery before refilling them which will maximize their power life on a shoot.

    These charge a partially used battery in about 2 hours which is plenty fast. They'll dump a battery and refill it completely in about 6-10 hours depending on how full it was to start.

    I own 4 of these units so that I can charge all of my AA batteries overnight between gigs without having to wake up in the middle of the night to rotate batteries in a single charger.

    this is a really good charger. i'm impressed with the individual battery charge indicators, and the discharge function. the problem is the recharge time. This has never taken as little as four hours to charge. It's easily double that amount of time.
    It's a good charger. but if you need a fast charger, this is not the one to buy.

        Comments about Watson 8-Bay Rapid Charger for AA / AAA NiMH or NiCd Rechargeable Batteries:

        Before getting this charger had a group of 2 or 4 battery chargers. Due to the nature of these ended with some batteries fully charged while others with 50% or less. Since the life of the set depends on the lower charged battery, I was getting less and less life.

        Once I got this charger, I was able to equalize the charge for each battery individually and restore the operating time of my flashes or cameras..

        Love this charger.

                  I bought one of these chargers to maintain my AA's for my flash units. I liked it so much I bought another. Recharge times were good and the discharge function is excellent. Unfortunately, one of the chargers has started to malfunction after just a couple of months of use. The indicator lights are random and some are dim. They don't all light when it seems the batteries are charged and I'm left unsure of the charge status. I wonder if this is just an odd microprocessor malfunction and I may need to replace it. Overall I love these chargers when they work.

                          Comments about Watson 8-Bay Rapid Charger for AA / AAA NiMH or NiCd Rechargeable Batteries:

                          I needed to handle power for a Tascam Dr-60 recorder with the battery pack, so 10 batteries running at once. This and the new Eneloops let me run for a long time.

                          This charger does a great job of clearly indicating power per individual cell. It also pegged a couple of bad older batteries from my set (accurately, since I then did some other tests and tried other chargers, finding them not totally dead but quite unreliable - would falter and ultimately fail in devices).

                          Works at a good speed, not burning out the batteries by overheating, nor too slow of a trickle so they won't take forever.

                          Recommended!

                              I am subtracting a star for the heat. How hot does it get? I think I can save a few dollars during the winter months if I use this thing as a space heater.

                              Other than the heat and the lame jokes the lcd display is clear and concise, charging times are quicker than my old charger, and it is compact.

                              I use this guy occasionally to give my AA's an extra kick and to reset the memory.

                              The LCD screen is really handy giving you info about each battery.

                              (only wish there was a way to know how long a charge takes)

                              Can't ask for much more from this product. Would deifnately buy again!

                                      Lets me pick out the batteries that need more work or are just done. I have real good volt meter but it takes a lot less time to put them in the charger, that I have to do anyway. I have a bunch of the same batteries so its helpful have the LCD indicate which one is not as good. Plus you charge up to 8 at a time each and each gets a full charge.

                                        Convenient 8 AA's charging "cradle", AC and DC car adapter.
                                        1) Takes longer time to fully charge 8 AA NiMH batteries, as advertised ~ 6 hrs.

                                        2) Let you see charging progress per battery.

                                        3) Light weight

                                        Only reason not giving 5 stars is the long time it takes to fully charge 8 AA NiMH.

                                        Definitely recommend this product.

                                          Easy to use, good functions and secure, since it´ll stop the charging for each battery individually.

                                              Works great. Love that I can tell how much longer needs charging by the display. Discharges batteries first, so I know I'm getting full use of them.

                                                  Product is reliable and works as advertised. I do not use "quick/rapid charge" options, so time for full discharging/charging is not an issue for me. I have four of these chargers, and they're an excellent deal for their price and performance.

                                                    Very good value, I bought the charger with 16 rechargeable batteries, Very easy to use, only drawback, it takes about 10 hours to charge to batteries up the FIRST time, otherwise no problems to speak of.

                                                    A bit pricey but appears pretty well made and seems to work perfectly. Have been using this with the Watson AA rechargeables. Seems as quick or quicker than my other chargers.

                                                            Most of the batteries recharge in about an hour.

                                                                Got this as part of a Canon flash package but I couldn't be happier with it. The charger is a solid well made unit in all respects. Its small, neat and works perfectly. The included 12V adaptor cord is a handy bonus.
