The Rayovac PS3 Rechargeable Battery Universal Charger will charge any size NiMH battery. This device will recharge up to eight AA or AAA batteries; four C or D batteries; or even a single 9-Volt battery. The PS3 is perfect for high battery usage households, and it is capable of recharging batteries over 1000 times. If your family or business burns through piles of regular alkaline batteries, grab yourself a stack of NiMH rechargeables and the Rayovac PS3, and start saving money.

Why Rechargeables
Today's high-drain, electronic devices demand rechargeable NiMH batteries. NiMH batteries actually last longer than alkaline batteries in most high-tech devices and they can generally be recharged up to 500 times. This high-volume rechargeability results in cost-savings that can add up to thousands of dollars. Plus, with Rayovac NiMH batteries, there are no "memory" problems -- recharge your Rayovac batteries any time, even if they are only partially drained.

Usage Tips

  • Always charge NiMH batteries before first use
  • For maximum performance, charge batteries prior to using if stored for more than one month
  • NiMH rechargeable batteries are available in AA, AAA, C, D, and 9-volt sizes
  • NiMH batteries can be disposed of with regular trash -- NiMH is safe for the environment
  • Universal charger recharges AA, AAA, C, D, and 9-volt NiMH batteries
  • Perfect for use in high battery usage households
  • Capable of recharging batteries over 1000 times
  • NiMH rechargeable batteries last longer than alkaline batteries
  • Recharger can save thousands of dollars in alkaline battery costs

Customer Reviews:

  • Bulky, heavy, but surprisingly smart and versatile
    I already have at least half a dozen smart chargers in the house, including top-of-the-line models such as the La Crosse BC-900 and Maha C9000, but I still wanted this Rayovac Universal Battery Charger (PS3) for the following reasons:

    1. It can accept C, D, and 9V batteries in additional to the standard AA and AAA cells.
    2. It can handle rechargeable alkaline cells in addition to the standard NiMH or NiCd cells.
    3. It has the potential to recharge up to 8 AA or AAA cells at once.

    So far, I'm very satisfied with this charger. Of course it is bulky and heavy. But that's to be expected for an unit that can accept four D-cells at the same time. For home use the size and weight is not an issue at all.

    I'm happy to report that this charger is a lot smarter than I previously imagined. Unlike a typical dumb charger in this price range (for example: the Energizer CHFCV Overnight Family Charger), the PS3 has four independent charging channels. That means I am free to charge different cell in any channel. Each channel comes with a status indicator LED, which goes out once the cell is fully charged. But most of all, this charger is smart enough to recognize the difference between NiMH cells and alkaline cell, and can pick the correct charging method accordingly.

    When an unknown cell is inserted into the PS3, the charger first starts off with a trickle current (800mA peak current at 10% duty cycle, or an average current of 80mA). Based on the voltage profile of this cell, the PS3 can determine whether this is an alkaline cell, or a NiMH cell. After two minutes, the duty cycle is increased to 60%, so the average current is now around 480mA. For a NiMH cell, charging will continue until a negative dV/dt is detected, in which case it switches back to trickle current again. But for an alkaline cell, charging current will gradually decrease with higher terminal voltage until it reached 1.65V.

    The Rayovac PS3 is designed to recharge the Rayovac 'Renewal' brand of rechargeable alkaline cells (which are now discontinued). The user manual warned against charging ordinary disposable alkaline cells, but I experimented with it anyway. So far, I have observed very good results with recharging Duracell alkaline AA cells [see warning below]. Of course, the capacity of a recharged alkaline cell is lower than that of a fresh cell, and it drops with each subsequent cycle. But since I can squeeze another half a dozen cycles out of an exhausted alkaline cell at no additional cost, I really should not complain.

    Back to the charger itself, I do have a complaint about its claim of "recharge up to 8 AA or AAA batteries". It turns out that each of the four charging channels can accept one to two AA or AAA cells, but the two cells are electrically connected in parallel. So in case somebody accidentally placed two cells of different battery chemistries (NiCd, NiMH, or alkaline) in the same channel, the one with lower voltage will discharge the other one. The charger may also get confused and fail to terminate correctly in such case. It is safer and faster to charge only one AA or AAA cells in each channel.

    1. Do NOT try to recharge alkaline cells that are completely exhausted (terminal voltage below 1V). It will not work.

    2. Do NOT try to recharge Energizer alkaline cells. Four Energizer AA cells I tested completely dropped dead after just two discharge/charge cycles. Two D-cells started leaking electrolyte a few days after charging. Luckily they were left outside and not being used.

    [Update on Jan 26, 2009]
    Out of maybe one dozen Duracell AA alkaline cells I have recharged, two started leaking electrolyte a few weeks later. I must now officially advise AGAINST recharging disposable alkaline cells: do it at your own risk!

  • Charges a myriad of batteries
    I've had this charger for about 2 years now and never had any complaints with this one. It's economical than most "rapid" chargers that are available and charges almost any battery needed for an average household (including 9v!). It does take a few hours to charge a battery fully; I leave them charging overnight and never felt compelled to get it done in 15 minutes. As far as I know, it conserves battery life compared to other rapid chargers....more info
  • Fantastic charger
    This charger is excellent for both conventional NiMH and the new "precharged" batteries like Eneloop and Hybrio.

    The primary reason for using this charger is that the charger is exceptionally good at keeping a maintenance charge on conventional NiMH batteries. As you should know, conventional NiMH batteries lose a good amount of their charge each day and need to be kept "topped-off" for on-demand use. The "precharged" Eneloop and Hybrio don't need this but the charger automatically senses the batteries' needs and uses the correct maintenance charge.

    This is not a timed charger, either. Most other chargers recognize the battery as AA or AAA and charge it only a specified number of hours no matter what capacity the battery which can vary greatly from battery to battery. Even worse those other chargers keep an unchanging "maintenance current" that can quickly burn out conventional NiMH batteries. This Sanyo charger, on the other hand, is designed specifically to maintain all battery capacity types at the proper maintenance charge 24-hours per day by continuously testing the battery's status so the batteries do not get worn out.

    You can charge one battery at a time or multiple batteries, but when charging multiple batteries each pair of batteries has to match. You can, for example, charge 2 AA, 2 AAA, and 1 AA, and 1 AAA, as long as you keep the connected batteries the same.

    An added bonus is that there is no power brick and the device never gets too hot.

  • rayovac battery charger
    The rayovac battery charger was the right gift for my family that wanted a charger for their video games. Its size does not take up much room and the range battery sizes it charges is more than acceptable. A good product for someone with mutiple gaming systems....more info
  • It's flexible and works well, with one limitation
    This charger was purchased to help my church use NiMH 9-volt batteries in place of the disposable alkalines that had powered two microphone body-packs. (As a "green church," we are committed to reducing our impact on earth's resources wherever possible. We researched the various options and found that the nickel metal hydride chemistry has less impact than other types of batteries, and also offers desirable electrical characteristics for this type of application.)

    Rayovac Rechargeable NiMH Battery, 9-Volt Size, 1-Count Package (Pack of 3)

    The charger is well-built and solid. The power cord does not have a "wall wort" transformer on the plug, but rather a simple, detachable line cord. The compartments under the sturdy plastic cover can accommodate a variety of different battery types. It was blister-packed, and easily set up.

    The limitation is this: for a 9-volt battery, the charger has only a single set of terminals. Although it can take up to eight cells for smaller batteries, it can handle just one 9-volt unit at a time. This should not be surprising, as most other cells output 1.5 volts nominal.

    In practice, this is not a problem. A red LED indicator illuminates when a cell is attached. The charger's controls monitor the battery charge condition, and step down to a trickle mode when charging is complete. The LED extinguishes as well. A complete charge of an exhausted cell takes about five to seven hours to complete. For the three 9-volt cells we have in rotation (two in use and one in reserve), I can store all three easily in the charger body.

    This is a well-designed product, even with the one-cell limitation for 9-volt batteries, and it is already saving us money while it reduces our waste footprint....more info
  • Good charger

  • Ok charger, but not good for trickle charging
    I've had this charger for a couple of years, and overall it is ok, but watch out for the following:

    -Although it charges 8 batteries at once, it's really only effective at charging 4 at a time. This is because the 4 "channels" mean that you put two batteries into a single channel. If one has more charge than the other, it will overcharge or undercharge one of those batteries.

    -The trickle charging feature doesn't seem to work well. Even when the charging light goes off, it still seems to put a lot of current through your batteries and they remain pretty hot. This extra heat tends to kill batteries.

    Other than that, if you need to charge a lot of batteries at once or need to charge 9v, C and D batteries, it's pretty good. Unfortunately, through my years of use, I've seen my rechargables have large variations in how well they've held up with this charger. I just recently bought the La Crosse Technology BC-900 AlphaPower Battery Charger and found that while some of my 2500mAh AA Energizer rechargables have a capacity of around 2200mAh, others are as low as 700. This speaks to my above comments regarding the issues I highlighted above. This charger is not a good long-term solution.

    Overall, if you need to charge odd sizes, you may like this charger, but if you mainly charge AA and AAA, you're better off in the long run with the La Crosse Technology BC-900 AlphaPower Battery Charger. Although more expensive, that charger comes with 4AA and 4AAA rechargables, a carry case, and 4 each of C and D size adapters (lets you use a AA as a C or D battery). Therefore, it's a good value and has a lot more capability to preserve your rechargeable battery investment....more info
  • great product
    Works well. does what it is suppose to do. Nice to be able to charge AA AAA C D and 9 volts at the same time. I would recommend this product....more info
  • Great charger
    Great charger for great price. Only one out there that I found that will charge 8 AA or AAA at a time or 4 C, or D's. Don't have to set a switch to tell it what kind of batter it is either. Automatically stops charging when fully charged so don't have to worry about overcharging. Very convenient....more info
  • Great Charger
    I purchased this to recharge my "C" and "D" rechargeable batteries. It works very well and does a great job. I like the fact that it has lights which go off when the batteries are charged. It is also very easy to use. I am considering purchasing another as a gift. This was purchased to recharge batteries for my flameless candles and I have not been disappointed in its ease of use of performance thus far. I would recommend this to anyone who needs a charger that will recharge all sizes of rechargeable batteries.

  • Good Battery Charger
    This is a good battery charger, that works well with all types of rechargeable batteries. At first, it can be a bit tricky getting D-Sized batteries in and out, because they really push the capacity of the charging bays, but it gets easier after you do it a few times. Overall, I am a satisfied customer....more info

    Love this thing, never need to buy batteries any more! Bought in August have had no problems at all....more info
  • Great universal charger
    With our first child on the way I decided it was good sense to go for rechargeable batteries all around - save money and the enviornment. I looked at all the chargers available here in amazon but none seemed to be as versatile or cost effective as the Rayovac. So far the charger has been great. It has charged all my batteries, energixer, rayovac, cannon and even some non descript batteries I got ages ago. The set up is easy to use and the lights ensure you know what is being charged and when. The only small gripe is that charging can take a while - but that might be the batteries themselves. Very good product....more info

  • Pretty good charger.. but.. (could be a little better)..
    I have used this Rayovac for some time now (model PS3) and here are my thoughts... It is a pretty good charger for different sizes except for 9V. It charges my for rechargable Energizer C's just fine (rayovac doesn't sell rechargeable c's, I have checked everywhere). The unit smells funny when charging like a heated-plastic smell. (don't stand by it) It takes the entire overnight to charge your batteries. (could be faster)
    Overall good, I would suggest to the makers to test and eliminate the smell and to get recharging abilities much faster. 3 1/2 stars....more info

  • Very bulky
    I ordered this item based on very positive reviews however what I failed to notice was that this is a very bulky product. I wanted to have it so that I can charge my camera battery. However when I recieved the product I realized that I cann't carry this easily with my camera as it is so bulky.

    I haven't used the product yet so it might be good in terms of functionality but won't be much useful to me due to its size when there are lot of compact products already available in the market....more info
