Identical To More Expensive Viatek Chargers
When I got my Maximal Power Charger, the first thing I noticed, is it appeared to be airbrushed black. The paint job is decent enough, with a nice glossy finish that doesn't attract fingerprints or smudges -- but a paint job none the less. It looked good, but it made me curious. So I came back to Amazon and did some investigating, and sure enough there are 2 other chargers being sold at much higher prices, yet look suspiciously identical to my Maximal Power. They are, the Viatek Re02 Renu-It Pro Disposable Battery Recharger and the Viatek RE02G Renu-It Pro Series Professional Grade Disposable Battery Regenerator/Used for AA, AAA, C, D & 9-Volt Batteries; at approximately $55 and $35 respectively. Well, I paid $25 bucks for my Maximal Power, and could care less that it's been airbrushed black as opposed to the silver the other two models came in. I actually prefer the black. All 3 are essentially the same battery charger, but Maximal Power went the extra mile in their product description, IMO, so I felt good that I picked the right one.
YES, It Really DOES Charge Alkaline Batteries Perfectly
I've had a couple battery chargers, way back when. But I always wished there was a way to recharge alkaline batteries. I'm sure battery manufacturers have their technical reasons why this is a bad idea; and make no mistake, one of those reasons is that they want you to keep tossing and buying batteries. So that mythic alkaline charger never seemed to cross my path... until now. I had every confidence that this Maximal power could charge rechargeable batteries just fine. But what I was most curious about, was if it indeed could recharge alkaline batteries as promised. So I went on a scavenger hunt around the house looking for alkaline batteries to recharge -- and believe me, we had plenty of dead gizmos laying around with dead batteries in them, so I had a treasure trove to draw from.
For my 1st set of guinea pigs, I settled on my old Eveready lantern. It's a battery hog, and I'd long since gotten tired of feeding it. I eagerly plucked out the 4 D size generics, branded with my grocery store's logo, so I wasn't expecting much. They were completely dead, but seemed like decent quality generics that shouldn't explode, so I popped them into the charger, one by one, with a bit of trepidation. The LCD on the Max Power charger began flashing as it read the batteries, then the screen switched to 'charging' and the little power bars started lighting upward in unison -- they were actually charging! Okay, so far so good. Those D cells were in there for hours, and every now and again, I'd check in on them to make sure I didn't have any surprise blow-ups. 8 hours later, the little red lights on the charger turned green and my D cells were done. Could it really be that easy?? I mean, it should be that easy if it indeed works as advertised, but I was still suspicious. I popped my freshly recharged cells back into my Eveready lantern, and presto -- IT LIT UP!! What The...!?!?!? My mythic battery charger was finally here!!
This Thing Charges Anything
Bolstered by the success of my first experiment, I scoured the house for all the dead alkaline batteries I could find; and there were a lot of them. I soon had an array of miscellaneous dead cells piled next to my charger and the assembly line was set to begin. The dead cells spanned the gamut of brands and sizes; from Duracell to no-name brand batteries I picked up at the dollar store. Even an old N size car remote battery that Max Power claims it can charge. This time around, I decided to go for something more challenging, and picked four of the most obscure AAA batteries that I had in my pile. As I popped them in one by one, the Max Power read 2 of them as "bad." I tried those ones in different slots, just to be sure, but the Max Power rejected them every time. This is good, because I don't need to be forcing a charge onto bad batteries, which will probably just blow up. So I tossed those, and just grabbed 2 more obscure brands from my large pile. And the Max Power began to happily charge the 4 AAA's that I selected. I went and got busy doing other things, and when I came back, just under 1 hour later, all the lights on the Max Power already turned green. Ah-HA! I thought. It couldn't charge them, just as I suspected! So I pulled the 4 AAA's from the charger, popped 3 of them into a little LED flashlight, and turned it on. BINGO! It lit up; and really bright too. I wasn't expecting it to turn on, so I was staring at the 9 LEDs when I hit the power switch, and blinded myself. As I blinked through the glowing dots on my retinas, I realized that the darn thing was working. It was as bright as it would be as if I'd popped in brand new batteries. Okay, now I was determined to make this thing fail. It took me a day and a half, and I ended up successfully charging every dead alkaline in my pile. Damn you, Max Power! (Extreme long shot of Earth as Kaio screams in frustration.) Just kidding, of course; I was tickled that this darn thing actually worked, as promised.
I soon learned that while this Max Power can charge pretty much anything, it didn't mean these old alkalines were suddenly good as freshly bought new batteries. Yes, it recharged most every dead battery that I'd found, with only 3 or 4 of them being read as "bad" by the charger. So I had a fresh pile of recharged batteries to experiment with. That's when I discovered that the manufacturer's description was accurate; the manual says it can only charge alkalines to about 80% power, which soon became evident with high drain devices. If I use these recharged alkalines on low power electronics, like LED flashlights, remote controls, clocks, etc., then they work just fine. But if I put them in a high drain electronic, that draws constant power, then the batteries quickly show their limits. I put a couple of AAs into a specialty lamp that I have, and it ran constantly for about 12 hours, before it started getting dim, and completely died 8 hours later. So while this Maximal Power can indeed recharge alkaline batteries, it's clear that they are best suited for low-drain devices that only draw power from the batteries intermittently. So don't go charging a bunch of D cells for your hunting flashlight or your emergency survival kit. IMO, recharged alkalines are best suited for less important uses. However, this should still prove to be a money saver, all the same.
4 Independent Channels
This charger can charge 4 batteries independently, which means you can charge 1, 2, 3 or all 4 at once. You can even swap a charged battery out for another one, while the other 3 are still charging. At first, I didn't think this was important, but as I worked through my pile of alkalines, I realized how convenient it was to just swap out fully charged batteries with another dead one. It really helped speed up the process.
The manufacturer's quotes seem to be pretty accurate. AAs take about 3 hours. AAAs take about 90 minutes or less. D's take around 8 hours, and C's maybe 5 or 6. It does seem to depend on how dead the batteries are. This charger doesn't run on a pre-set cycle time, but rather, adjusts it charging time, depending upon each battery's characteristics.
Don't Charge Alkalines More Than 30x
The manual suggest that alkalines shouldn't be recharged more than 30 times. They say because the batteries were never meant to be recharged, they can become unstable if recharged more than 30 times. That's not a huge number, but if you think about all the dead alkalines you probably have laying around, then we're talking about a lot of recharged batteries. I got a silver Sharpie and have been marking each battery whenever I charge it, so that way I can keep track of how many cycles each one has gone through.
The LCD screen on the Maximal Power is a decent size, and easy to read, provided you are in good lighting. A backlit screen would have been a nice touch, but isn't completely necessary. I've got one of my little LED flashlights with freshly charged alkalines in it resting next to the battery charger, just in case. The screen does give limited information, such as Charging, Ok, Bad, Discharging, and 4 battery icons that independently show the power status while charging, with ascending bars. It would have been nice if the screen also told you more about the battery voltage, like a battery tester, since it clearly has this capability, but I just got a $3 battery tester, so I'm good.
Decent Quality Build
This is a no frills battery charger. There's no fancy packaging, and it's very simple and straightforward. Everything is well laid out, and easy to operate. The lid opens nicely, and is clear, so you can see through to the batteries. And the charging lights are just simple LEDs, but they are easy to see, and go from red to green when the batteries are done charging.
Yes, this charger does turn off automatically once the batteries are fully charged, and enters Smart Mode, which basically trickle charges the batteries to keep them topped up until you remove them or need them.
No Noticeable Heat
I was pleased to see that the battery charger barely gets warm to the touch, even after a straight day and a half of charging. The batteries themselves, don't even seem to get warm at all, which is a good thing.
No Funny Noises Or Quirks
I read some reviews that said the Tenergy chargers can make high-pitched humming sounds, which I'm happy to say that this Maximal Power does not do.
Included In The Box
The battery charger, a power adapter, and a spartan user manual; my favorite kind.
My Tenergy LSD rechargeables came charged up, but I popped them into the Max Power anyway, and it did light up green. I also popped in fully recharged alkalines, just to see what would happen, and the Max Power immediately recognized that they were full, and lit up green. So that's all good. I did charge some other rechargeable batteries that I had, and all functioned as it should. After recharging all those alkalines, it was kind of anti-climatic to charge actual rechargeables, but all worked as it should. This thing even recharges 9 volt batteries, but only 1 at a time.
I absolutely LOVE my new Maximal Power battery charger! It's everything I ever wanted in a battery charger, and then some. I'll still be buying regular alkalines for my emergency flashlights and important electronics, but I'll have an endless source of alkalines to recharge for my less important devices. And naturally, I have an excellent charger for rechargeable batteries too. And at 25 bucks, you'll be hard pressed to find anything better for the money. And if you feel like spending double to get this exact same thing in silver, then by all means, go ahead. But the black looks pretty darn cool to me; and I'll spend the cash I save on extra batteries. This one's a keeper.
Update - If you need a great battery tester check this one out: SODIAL- Battery Tester Volt Checker for 9V 1.5V and AA AAA Cell Batteries
I used it to test some AAA alkalines before and after recharging. A set of Kodak AAA batteries were charged back up to 1.56 volts with this charger, and tested with the battery tester above. Cool. Still really like this charger. Works very well.
Update 2/16/13 - need some good battery storage cases? I got these and like 'em: AA / AAA 4 Cell Battery Storage Case Bundle of Six Cases
Update 6/5/13 - It seems several of the alkalines I've recharged became unstable and leaked. It happened across the board regardless of brand. I'd say maybe 6 out of 12 batteries leaked that I had stored away. But one's that were recharged and in use seem to be fairing better. Not sure charging alkalines will be as fool-proof as I thought, but I'll likely keep doing it. Though sticking with Tenergy rechargables may be the better way to go.
1. Charges all NiMH and Nicad AAA and AA to 1.43+v.
2. Charges alkaline C/D cells up to 90% of original nominal value.
3. Is able to charge buttonless type rechargeable batteries (ex. Saft VRE C cells).
4. When charging is complete, C cells & AAs are cool to the touch. Only AAAs are warm.
5. Has a very good trickle charge that will allow full charge of all battery types.
6. Has non-backlit LCD display that shows current charging status.
7. Bright LEDs to show discharging (amber), charging (red) and full charge (green).
8. Four individual slots that will allow mixing of the same battery type.
1. Discharge rate of NiCads are not even across the charging ports.
2. Has trouble making proper contact with AAA batteries. Pushing down on batteries allows proper contact.
3. Air-brushed with black paint.
4. After several charging cycles on Nicads, port 4 will no longer discharge.
5. Has no selectable charge/discharge rates that some of the better chargers have.
All voltages were measured with a Fluke 115 DMM.
All other measurements were made with a Maha MH-C9000 analyzer.
Good charger overall. Now if it will only last.
I am not going to attempt to use this for alkaline batteries, too many risks with leakage of caustic chemicals.
After I learned that cadmium is toxic to humans, I no longer use Ni-CD batteries. I will not be using the FC999 for that either. Your choice there but I recommend washing you hands after handling the metal case of a Ni-CD battery. ;)
That's just me
