Just in case you were wondering: 1200 mAh (milli-Ampere-hours) means the battery can store an amount of energy that is supposed to be enough to power a device a device pulls a constant 1200 milli-Ampere (=1.2 Ampere) for one hour straight.
But also look at the existing comments regarding mAh, others have mentioned that a lower-capacity battery may hold a charge longer.
It’s good to have a choice though: 800 mAh ones or 1200 mAh ones for the same price The 1200 ones on Amazon only have one negative comment of someone who seems to have had a warranty issue.
idk about the newer Duracell rechargeable batteries because I’ll never buy them ever again. I had some a couple of years ago because it was a good price from a name brand for 8 batteries, oh my god terrible usability, life, and output. the cameras that used them only took a few pix before dying, the xbox controllers turned off and kept flashing like they had no juice occasionally turning off. they didnt hold a charge after 3 months after buying them. i had to start using them in tv remotes and even then discharged quickly, and they were supposed to be the stay charged type too. i shouldve just stuck to Rayovac they never ever let me down even after years. i just happened to lose them eventually over time but never ever let me down.

As I understand it, CPU controlled third-party chargers are the best way to go. The standard chargers that normally come with these types of batteries just pump juice into them for 8 hours no matter what. The CPU controlled ones apply a configurable amount of current and can do advanced recharge functions (like bring old batteries that don’t normally charge back to life). I own a powerex brand I got from newegg.

Perhaps just as bad as “dumb” fixed-time chargers are chargers that force you to charge in pairs. The problem is that pairs of batteries rarely discharge equally. That means you may be charging an 80%-depleted and 68%-depleted battery together. The second battery will finish charging first but the charger won’t turn off until the first battery is also full. That means the second battery will overcharge, damaging it.
Folks, buy yourself a charger that charge batteries individually. preferably with selectable current output. Use slow charge to protect the batteries if time is not crucial. Good models include the LaCrosse, Maha and Powerex. Excellent discussions of each are available on Amazon.

Those are regular NiMH batteries and cannot be compared with these “pre-charged” Duracells. Regular NiMH and NiCad batteries suffer from self-discharge. A fully charged battery will be empty in a few months even if it’s never used. Don’t quote me, but I believe a regular NiMH battery loses 20% of this energy the very first day in storage, and 4% every week thereafter. That’s why those batteries should never be used in emergency equipment (i.e. flashlights, radios, stun guns), clocks, alarms and sensors. They’re good, however, for things you use and charge frequently, i.e. cordless phones, remote controls, daily-use flashlights, etc.
These Duracells, like Eneloops, are Low Self-Discharge (LSD). That means they retain a charge significantly longer, almost like regular alkalines. LSD batteries should retain about 80% of a full charge after a year.
To fairly compare these Duracells, look for other batteries that say “pre-charged” or “low self-discharge.”
So my question of the moment which is partially answered earlier, but I like confirming things, is will these work with the Kodak charger bundle Woot offered recently?
I know the charger isn’t super duper hi-tech like some of the others people have suggested, but there are budget limits sometimes.
Yay, Woot! Finally, thank you! I thought you were never going to offer AAAs PERFECT timing, as I was just starting to look around for the best price. I’ve been seeing 4-packs of Duracell for around $10, so as far as I’m concerned, this is a GREAT deal.
I bought Duracell precharged/rechargeable AAA batteries (the same as or very close to these) last Christmas, and I am looking for more because I only have 4 right now. All of my flashlights and my headlight take 3 AAAs, so I never have fresh ones ready when the set I’m using need recharging.
I have REALLY put the ones I have through some use. I haven’t officially tested or timed them, but they seem to do as well or even better than non-rechargeable alkalines. I like it that when they’re done charging and I unplug the charger, I can let them sit for days or even weeks and the batteries still have a nice charge when I go to use them. I don’t know if it’s the charger or the batteries, but they do take a while to charge - several hours. I have a feeling it’s the charger I use, and I hope these will charge faster than that with the charger I bought on a previous woot (that came with AAs that I don’t use). Even if they don’t, I love these batteries enough to say “I’m in for THREE!” (I do a LOT of gardening outside at night, lol).
I WAS in for 3 - until I saw the tax on my order. Amazon and Woot, you have no idea how much business you just lost. Between the two of you I spent well into the 5 figure range last year. Not anymore. You’ll be LUCKY to get 4 figures out of me now. Nope, I’m not interested in paying tax on items I have to wait to receive. It’ll have to be one heck of a deal for me to buy on Amazon or Woot now. Thanks for making this change right before I renewed my Prime account, at least. Saved me from wasting $40 on free shipping with a company I will no longer (or rarely at best) buy from.

Because they have a choice in ignoring state laws demanding tax be collected.
If you want to be angry be angry at your state, some of them tax all online businesses even if they have no holdings in the state.
50 possible states with 50 different tax rates, yeah Amazon wants to deal with that nightmare.
Just so every1 is aware…I bought these last time (a week or two ago), and though they appear to be the white tops in the pictures…they are not. They are indeed the black tops. The difference seems to be the white tops are re-branded eneloops (made in Japan) and the black tops are supposedly the Rayovac hybrids (made in China). They are still really good batteries and work well, I just wanted to clarify, since the photo is misleading…
Eight individual charging bays with digital readout.
Also, stay away from the Energizer precharged. They’re crap.

I would get the Maha Powerex MH-C9000 Advanced Analyzer instead. Yes, it only has 4 slots, but it does so much more and $3 less. Check the features of both before you buy.
Edit: Actually this link on Amazon is even a couple of dollars cheaper then the other one above. Oh, the other one comes with a carrying bag from a different Amazon vendor.
Actually, if you go to this link there is a very detailed description of the MH-C9000. Well worth a look.

If it’s PA, it’s because Amazon opened a 6th warehouse in the state, exceeding the limit, and we now must pay sales tax starting today. (And if you’re implying Amazon doesn’t check state tax laws ahead of time and this is a surprise to them… they wouldn’t be in business by now if that’s how they operated. lol)
BTW, considering the conditions I’ve seen reported at those warehouses, (like stationing ambulances to take passed-out workers to the hospital instead of cooling the 110+ degree warehouse) Amazon should at least clean up their act at the old ones before opening new ones, IMO. But I digress.
I was already planning to reduce my Amazon purchases because of it, I didn’t realize it would count for Woot! as well. This displeases me.
At least this will cut down on my impulse buys. 58 Woots in less than a year is probably a bit excessive.
If you’re going to use rechargeable you must get a decent charger. Granted that’s an even further investment but it makes a big difference. You need a charger that can recondition the batteries, this will add years to their lives and make the charger cost effective. I have a PowerEx charger and use Eneloops since with the Eneloops you know what your getting while with these Duracells its a crapshoot.

Hmmm. How is two of the batteries dieing completely after only a couple weeks a “warranty issue”?
[QUOTE=sdc100, post:34, topic:364182]
It may not matter in advanced flashlights. They have a circuit that boost low voltages so that the light output will be fairly consistent throughout the life of the batteries. The light will just go off once the voltage drops too low to be be boosted. In an unregulated flashlight, the light will gradually dim instead of just going dark one day. There are advantages and disadvantages to both approaches.
If regulated, the flashlight will be equally bright with NiMH and alkalines, but won’t last as long with NiMH.
[/quote]
These Black and Deckers appear to be unregulated because I’ve already had two sets of normal batteries die in two different lights… dimmer… dimmer. But since they’re LED, they don’t start dimming until the batteries are pretty far gone, so I’m not sure if the NIMH would pull it off or not.
They’re handy little flashlights, though. I use one every day when I don’t want to bother turning on a lamp just to see where I put the remote or something.

I got these last time and my tops are black. 2 of them lasted about 15 days in my outside weather transmitter. I have not charged them yet though since they kind of come precharged.
[/quote]
My LaCrosse outdoor sensor eats rechargeable batts also, but alkalines will last over a year, so I pretty much relate this to the NiMH’s initial voltage being 1.2V and the alki’s being 1.5V. In other words, the batteries are fine—the sensor is just picky about the voltage it wants.
Wow… reading the comments it sounds like rechargeable batteries have come a long way from my box that took purple rechargeables and occasionally made the batteries burning hot.
The 1200 ones on Amazon only have one negative comment of someone who seems to have had a warranty issue.
