THE IMAGE ABOVE IS A PAID ADVERTISEMENT What are you guys having good luck with at present? nimh engergizers, and rayovac AA's and a charger a try, the energizers totally suck, run down after about a week off the charger quick and dont have hardly the capacity of an alkaline even fresh off the charger, the Rayovac with the the silver metallic wrappers are doing well, seem to have hardly any loss, and more run time than an alkaline in a Garmin Oregon GPS, just curious how they compare to the eneloops.

It seems that most of the leaky batts I have a problem with are Duracells.

We've been switching over to Eneloops the last few years. I've had one go bad (it's possible), but overall I am very impressed with their longevity and reliability.
The one that went bad was used in a device that had instructions telling me not to store batteries in there, so I log that as user error on my part. Aside from that they have been 100% perfectly reliable, and I use alot of them. ETA: am I reading right that you are storing your batts in the crisper drawer - is that in the refrigerator? Uh... why?!? Cold will kill them lickety split. |

i have a mixture of eneloops, which work great, Duracel alkaline and Ever-ready. So far, the Eneloops are the best at long term storage, due to low self-discharge.
i have noticed an increase in the Duracell leakage issues, with my home devices, but didn't log it specifically. At work, i have a few hundred devices that use batts, so i use a mixture of Duracell/Everready. No major issues that I've noticed. I am putting more money into Eneloops and buying some D/C batt spacers from Amazon. Costco doesn't seem to ever have them anymore. And i'm going to buy another charger so i can charge more than 4 at a time. I usually use my solar panels to top off the batteries. |

Years ago a caver told me he would only use Duracell batteries in his lights because they guaranteed their batteries and would replace equipment damaged by them. That was a long time ago–– before LEDs, NiMHs, and other such things. Here's their guarantee today: If you're not completely satisfied with a Duracell product, contact us.
All of our batteries are guaranteed against defects in material and workmanship. Should any device be damaged by these batteries due to such defects, we will either repair or replace it if it is sent with the batteries. Send with postage prepaid to: Duracell Berkshire Corporate Park Bethel, CT, 06801 Att: Consumer Dept. It can be found at the bottom of this page: http://www.duracell.com/en-US/battery-care-disposal.jspx So, if anyone has lost equipment due to leaky Duracells, ask them to make it right. |

They still do stand behind their products. They sent me a check for a GPS that had batteries leak in it just a year or two ago. FYI I had Energiser brand batteries leak in an EOTech recently, but fortunately I caught it before it did any damage. One thing I will note for pretty much all "name brand" batteries is that the ones included with items you may buy are not the same as the ones you buy standalone, they are "original equipment" batteries, are made in China and I'm fairly sure do not carry the same warranty as the USA retail batteries. Test the device with them and then chuck them and replace with proper USA batteries. |

I had Energizers that had one year left on the date.
They destroyed some nice Princeton Tech lights that I had. Energizer cut me a check. |

If it had any merit, you would think batteries would be kept in the refrigerated section of the grocery store... I use the cheapest batteries I can find - usually panasonic or rayovac alkalines on clearance from target for $.10-25 per 2 pack. I hav been using them for the last 5+ yeas and not had any issues with them. I store them in a rubbermaid bin in my home or the basement - nothing special. I do have some that I leave in flashlights that are in the car year round in high heat and very cold temps and haven't had any issues there either. The only leaks I have ever had were with duracell or energizer batteries or the no brand chinese stuff that commonly comes in toys or cheap harbor freight-like flashlights and other things. |

There is a fair amount of documentation stating that storing batts in reduced temps extends their lives. That is to say, sealed in airtight containers, in refrigerator-type temps. I believe that freezing the batts is theoretically a further extender of batt life. Just dumping your batts, in original containers, into your fridge, might not be a good thing, what with moisture and all.
After all, the flashlight in your car has its' batts pretty well frozen during the winter, and I don't recall any complaints from users about their glovebox flashlight's batts eating it from the inside-out. Maybe I missed something. |

The 9v do it to me frequently. They don't seem to last more than a year in storage.

I've lost several Mag-lites to Duracell, including 2 LED models this year. 3 or 4 D cell models. Duracell has replaced them all.

They probably would, if batteries didn't sell in a reasonable amount of time. Here's the typical shelf life for alkaline batteries, stored at various temperatures - It's from the Alkaline Battery Application Manual, published by Energizer:  As the chart shows, storing your alkaline batteries at low temperatures does indeed increase their shelf life drastically. However, the shelf life at room temperature is sufficient for most consumers - which is why refrigeration isn't commonly used. Note that most other battery chemistries (carbon-zinc, NiCd, Ni-MH, lithium primary) follow the same general trend - Cold storage drastically reduces their self-discharge rate: Lithium primary:  Carbon-Zinc:  Storing batteries in the freezer further increases their shelf life somewhat, but also tends to make their seals brittle and prone to leaks. For this reason, storing 'em in the fridge (above freezing temperature) is the best approach, IMO. |

Thanks for posting these graphs, Skibane! I knew I had seen these here before! I only have 3 sets of nimh, I suppose I might charge up the sucky energizer lithiums and measure the voltage drop vs time at room temp, vs crisper temp and see if that doesnt show the basic premise as fast as these self discharge, that is unless these are THAT bad which they very well may be.
Speaking of batterys, we just got in some "Industrial" duracell PROCELL at work, are these worth looking into for long term preps as far as you guys can tell? For example these are the 9V 550maH, the same as the "retail", but almost twice as cheap. The specs seem identical, though the packaging is just different. I borrowed one to test in the smoke detector. |

I'm in the battery charging business. The charts that Ski bane posted are spot on. NASA stores all their batteries around 4°C..... Another way to think of this is: A battery is a chemical reaction waiting to happen. All batteries have some level of self-discharge -> leakage -> a slow reaction is happening all the time so the battery can produce larger amounts of energy on demand. There is a rough rule that a chemical reaction rate doubles for every 10°C of temperature rise. The inverse is true for lowering the temperature. Lowering the battery temperature 10°C should reduce self-discharge by ˝. You asked why the batteries aren't stored in the cooler at the store…. After 23 years in the battery charging business I can tell you one thing. Battery manufactures want to sell more batteries, not less. DeWalt makes more from selling replacement batteries than they do from the original tool… |

Im afraid. I have very expensive scopes with illumination and night vision that take AA batteries.
now after ever use I take the batteries out. Is there a special mil spec battery thats AA that doesn't have this issue. How about a Duracell or energizer sub brand , "lithium or what ever |

I am not sure that Duracell actually makes any batteries at all. I know that a fair number of their batteries come from other producers. As best I can tell it is mostly a brand name and for all I know may not make any of the batteries they sell under the Duracell name.
I will say this about alkaline batteries. There is almost no difference in quality between the major brands. I would include most house brands as well, since many of them are made by a well known battery manufacturer and are the exact same battery as is sold under that brand name, just with different labeling and packaging. I would avoid the low end Chinese batteries but many perfectly good batteries are made in China. |

Rule of thumb for alkaline batteries, remove them from the devices when you are finish using them.

Buy your batteries at Costco guys. They sell Duracell and Eneloop (no energizer junk) and they have a very relaxed return policy. So, in a year if they start to leak, take back for a return or exchange and let them deal with Duracell.
