Given anything else being available (at normal prices), I would not put them in my gizmos if they were FREE.

I use AA's / buy devices that use them wherever I can. ENELOOPS.

But, I use mostly the Sanyo Eneloop battery, which has great safety, reliability, energy density, and lifetime cost. They hold 90% of the charge for a year, and charge quickly and easily in a $30 "smart" charger. These are "low self discharge" (NiMH) nickel metal hydride rated for thousands of recharge cycles, and are generally acclaimed by virtually all the techie types.

Available at lots of online sources, and Costco stores at a couple of bucks each, four of these will have capacity to run a VERY powerful flashlight for hours.

I also keep a bulk pack of the Costco alkalines on hand (shelf life is 7 years); ICOZ (in case of Zombies).

Smart move. By the way the AA batteries are the same AAA batteries inserted into a AA shell.

I yearn for the day when Woot sells rechargeable batteries. They will get so much of my money.

Wow. What a waste.

You'll always need batteries.

If your device does not typically come with (or recommend to be used with) Carbon Zinc or "Heavy Duty" (Zinc Chloride) batteries, then you probably should not use these batteries in there. Even then, alkaline batteries will last at least twice if not 4+ times compared to CZn or ZnCl.

Some devices that come with CZn/ZnCl batteries:

- Simple IR (infrared) remote controls
- Simple clocks and AM/FM radios
- starter batteries for cheap 3-AAA LED and other low-powered flashlights
- Leakfrog

For alkaline and especially for these CZn/ZnCl batteries, check periodically to see if the batteries are still working and not leaking. I doubt the Leakfrog can detect an internal battery leak.

Don't use CZn/ZnCl in anything that requires bursts of power:
- wireless (electromagnetic not infrared) transmission devices: game-console/toy/alarm controller, temperature sensor, First Alert Smoke Alarm with OneLink, mouse (especially those that uses 1 AA cell)
- loud alarm devices: smoke/CO alarm, they'll work during standby but may not have enough power to chirp for hours until you come home to remind you of a low battery or CO condition, Leakfrog runs off 3 AAA to partly alleviate the power problem.

... or high current devices (consider alkaline or NiMH rechargeables):
- anything with motor
- high brightness LED flashlight
- digital camera

... or devices that require reliable power:
- emergency use devices (car flashlight, emergency radio, etc)
- anything you don't want to get ruined by potentially leaking batteries

Personally I use CZn/ZnCl batteries only when they're bundled with devices, and replace them with alkalines when they die. Store brand or bulk quantity alkalines are cheap -- $0.25 every day and sometimes below $0.20 each. I rarely have any trouble with alkaline batteries, brand name or not, USA or imported, save for the occasional leaky old cell. Rayovac alkalines seem to be the worst offenders by a small degree, some leak even in the package within 2 years of storage ... so much for Made in the USA.

Dont waste that hard earned money on these poopy batteries.

I like these "bulk battery" deals every once in a while. Remotes, the back-up in my alarm clock, and other such things.

I am confused about one thing. The whole smoke detector story in the description. I don't think I've ever seen one that wasn't a 9V. Of course, that might make it funnier, ordering the wrong type because neither choice is correct.

I bought these the last time they were posted on Woot! (I love you Woot!), but I would NOT buy them again. The battery life is horrible. I've used them primarily for my Wii controllers, and I don't play my Wii that often. It seems like I've had to replace them every other day, with no more than an hour of Wii play per day. I don't think the savings are worth the waste. I may be a chump, but it seems to me that a 4-pack of 'regular' batteries would be the equivalent of one of these discount 20-packs. I would not trust putting these in an alarm clock or anything you depend on. My two cents.

jjfahey wrote:Why are these still being produced?

I wonder the same thing.

Non alkaline cells like these use a zinc can. The can is consumed as part of the reaction that produces electrical potential. This makes "heavy duty" class of cells prone to leakage of the electrolyte.

They are also less capable in delivering sustained current.

Not sure if these have a sealed metal outer jacket, it's better if they do as that helps leakage, but it also uses up space in the overall dimensions of the cell. That reduces the capacity (physically and consequently in terms of energy).

Alkaline batteries are sooo much better, much more capacity and they rarely leak.

Seriously, a company should at least ATTEMPT to help the world by not selling crap, low-life throw away batteries. I don't mind paying the extra and not being lazy: ONLY USE RECHARGEABLES, please.

Bought my niece and nephew some annoying toys that use batteries and I want to make sure that they don't run out, thank you woot

goldnhawk1 wrote:Bought my niece and nephew some annoying toys that use batteries and I want to make sure that they don't run out, thank you woot

Just make sure they don't leak in their toys. These are not good.

Not great for electronics you depend on. These run out very fast!

I would be disappointed if I got this in a Band of Corpulents. These "batteries" are the closest woot has come to just selling outright landfill-enhancing garbage. These relics don't even belong in the bargain bin.

Have a set of 8 Panasonic 2100mah NiMh from Costco that are 7 years old now - still going strong (still at 1700 mah capacity). I also use Powerex 2700mah NiMh AAs - about $2.50 each. Have to watch the self discharge though - need to be topped off about every 6 months. I let a set of 12 set too long (well over a year)and they progressively wouldn't hold much of a charge anymore. Powerex was very nice and replaced all 12 of them even though it was my fault. I also used to charge them as a group of 4 in series - not a good idea if each one has a different capacity (as they age). Bought a 4 slot independent charger that also can do a discharge/charge cycle with capacity reading and a slow charge, brute force to rejuvenate older rechargeables. My camera and camcorder are much happier now.

A far better buy would be some NiMH AA and AAA batteries and a quality charger. They'll last for 100s if not 1000s of recharge cycles.

Hear, hear!

Use the math Luke! don't buy disposables.

For instance, w00t!'s overlord sells an 8-pack of pre-charged 2000mAh rechargeable NiMH AA batteries for $18.64 and a great charger (La Crosse Technology BC-700 Alpha Power Battery Charger) for $37.95. Over its 1000 cycle life, each battery will use around 2.7kWh of electricity for charging at a cost of about 30¢ (assuming 11¢/kWh).

All in this primo setup costs just under 1¢ per use vs. 18¢ per battery from w00t!
($18.64 + $37.95 + $2.40) ÷ 8000 = $0.007

Thumbs Down on this one
they work for a few minutes and quit

I bought these last time, and they are too short to fit in a AA battery slot. *sad face here*

dliidlii wrote:Smart move. By the way the AA batteries are the same AAA batteries inserted into a AA shell.

Ummm... no they are not. Open one and look for yourself. I think you are confusing that 9v batteries are 6 AAA cells inside the case.

Just in case your Nissan Leaf runs out of juice on the way home from grandma's...

Seriously, all of these batteries are going to end up in a landfill somewhere since most people don't dispose of them properly and instead just toss them in the garbage. Battery technology has come a long way since the 80's...

I suppose you could use these if you have two dozen remotes at home or if you are an electronics hobbyist.

I bought this on the last woot (a month ago?), and I must say, they SUCK.

I primarily bought them for my remote controls, game controllers and other media room devices. I have already changed out my universal remote TWICE and my XBOX 360 controller TWICE. I am totally not exaggerating. It's like watching the battery drain right before your eyes. I should have just paid for good quality batteries so that I wouldn't have to change them out as much as I am now.

Hell, I barely even game...I use my 360 controller mostly for watching Netflix and Hulu...and that's not often!

Chit!

worthless

googlewoot or whomever they are now are on my BOClist. Been stymied form the Barrels of Crud last 3 wootoffs and am now entering Boycott phase. Especially on Fujilicious batteries.

I got some of these in my BOC and used them in my electric tooth brush... They lasted about 3 days before there was a noticeable slow down of the motor and they needed to be replaced.

I beg to disagree, if you open up a 9 volt battery you will find it is loaded with 6 AAAA batteries used to make the nine volts and is where I get my AAAA batteries when I need one.

these guys are stealing your money... got batteries on last woot and went through two boxes of AA in 20 minutes trying to take pictures... each pair took one pic then the camera went dead... should label this b(ox)oc....

How funny. I just re-watched the Matrix trilogy yesterday. :P

I bought these last time, around Christmas and they stink! They ONLY worked in remotes, and not for long. Any other type of device, even a wireless mouse, and it was a no go. FAIL!

Be careful what you wish for....they may just get the crappy rechargeable ones....

Terrible product!!! I got the batteries from a previous sale. Many of them are dead on arrival. I could not record a special event because of the dead batteries!!!

if my batteries die is that covered under the warranty?

Bought these EXACT same ones from the Daily Deals on eBay. Use them for my Xbox controller. Went through 20 within 8 days!!! They are horrible. You get what you pay for.

Bought these last time they were for sale. They're perfect if your planning to use them in a sock to beat your cellmate. I'd recommend a different battery though if your going to use them in electrical devices.

These are c__p batteries. They have a shelf life of about 1.5 years, and will leak nasty zinc chloride, which is more hazardous and damaging than the leaked stuff from alkalizes.

gwbaker wrote:Bought these last time and I would advise a pass on these. They are clearly marked heavy duty rather than alkaline. BUT, they last about 1/5th the time as a Duracell or Energizer alkaline.

No, these will not "leak nasty zinc chloride" despite being "clearly marked heavy duty." Here's why: THESE ARE PLAIN OLD CARBON ZINC BATTERIES, AND NOT TRULY HEAVY DUTY (ZINC CHLORIDE). When these last appeared on Woot, someone contacted Fuji and a rep admitted that. See this post.

This partly explains the poor performance everyone is getting. If these are truly Heavy Duty (zinc chloride), I'd actually recommend them. For many solid state applications, heavy duty batteries are a better value than name brand alkalines. See this post, based on data from Energizer, one of the largest alkaline battery manufacturers. Their research shows that alkalines usually last only a bit over 2x longer than heavy duty batteries. Yet they often cost 3-4x as much. So true heavy duty batteries are still a good choice.

Other have said this, but it can't be said enough: DON'T BUY THESE!

I can buy 100 AA/AAA batteries on Amazon for $25 WITH shipping. And that took me about 3 minutes to find.

Alkaline batteries are about 2500 mAH
Heavy Duty batteries are about 900 mAH

So unless it costs over $30 for 60 Alkaline batteries (it doesn't) you're losing money by purchasing these.

Even if you do want to give people crappy batteries on Christmas, you're still paying more for the privilege.

Just don't buy these! They suck

That's only true if you buy name brand batteries (Energizer, etc). If you buy generic alkaline batteries you will actually pay about the same as you would for a heavy duty. And despite what Everyready would have you believe, all alkaline batteries are the same, so buying name brand alkaline batteries is a waste of money.

I should be resisting, but...
Here's the best I could find at Amazon, almost $26 for 60 (this is not an endorsement, just asking for a link to back this up). I might test the leak frogs (with similar batteries, I think) when I get home from work:

http://www.amazon.com/20-pack-Fuji-Extra-Heavy-duty-Batteries/dp/B006MQOIMC

Makes you wonder if the seller bought them off of woot before and is reselling them on Amazon (versus the same supplier?) since they have the same expiration date of 10/14 as last woot in December and this one.
