I am using regular Duracell batteries in my cab 2 & cab 1 ,& they last a long time ,i was thinking about using re-chargeable batteries ,however i am using the re- chargeable ones in my mouse & keyboard right now & they just don't last ,i put new rechargeable's in my keypad & 1 week later i had to replace them ,what is the most accurate way to test the batteries to see if they are really run down ?, would buying a tester be worth it  ?,& do i need to put a load on the battery to get an accurate reading ? & last question what would be a good brand of tester to buy ?  Thanks for any help you can give .

A few years ago I reviewed a couple photo sites and the consensuses was Panasonic eneloop pro is the best NiMH battery out there.  They hold a charge for a long time and last the longest time in use.  I have 6 sets of the AA size and they have been great.  I use them in digital cameras with flashes which is a high drain usage with the flash.  They cost more than other NiMH batteries but are worth it.

The only issue with all NiMH batteries is at full charge the voltage is only 1.2 volts or so.  This it too low for me to use them on my Cox Cable remote controls and maybe some other application.

I just us a Harbor Freight VOM to check voltage but most of my digital cameras have a low voltage indicator.  I do not have a need for train batteries as I run post war conventional control trains.

RickO ,I have bought these a few months ago ,they are Tenergy also 1.2 v ,i get many months out of the duracell batteries in my cab 1 & cab 2,although i don't run trains very often.

Mustang ,I do have a meter but i have read that you need to put a load on the battery to get an accurate reading ,non sure the right way to do that  .

I don't spend that much time on the computer ,mostly in the evening checking e-mails & the O -gauge forum every night ,so the batteries shouldn't run down that quick . I just put the duracell batteries back in the keyboard ,so i will see if they last any longer.  

Absolutely there must be a load on a battery to test it.  Harbor Freight has a bottom of the line tester (I've seen it between free and $7--right now it's $6.79 on line) which has a test position.  I find it works well for 1.5 volt and 9-volt batteries.  If you get rechargeables, get NiMH.

I don't know why your keyboard goes through batteries so fast.  My keyboards are USB cable.  The mice run months on an alkaline.

I don't know if Duracell rechargeables tend to leak.  But for alkalines I switched to Harbor Freight's top-of-the line, which are price attractive.

I've had a lot of Duracell batteries leak for me, and some research online indicates that they are indeed more prone to leaking than in the past due to some unspecified design or manufacturing change.  Since I don't like cleaning up after leaking batteries I'm using Rayovac or Energizer batteries right now.

I've had tons of Duracell and Costco's Kirkland brand (made by Duracell) leak.  I have removed them from my inventory, never to buy them again!   The leakage warranty is a joke when you actually read the fine print, unless it's an expensive item, it'll cost you more to claim leakage damage than just replacing it.  If it's an item you can't get anymore, (think MTH remote), you're out of luck!

All alkaline batteries eventually leak (not just Duracell).

If you want disposable, single-use batteries that don't leak, then get some Energizer Lithium (not to be confused with "lithium ion").  For disposables, they're expensive but they don't leak, they don't self-discharge, and they have a 20 year shelf life.

I use Energizer Lithiums in things like my camera flashes and flashlights.  Those items may sit for months or years before I use them.  When I pick them up, I want them to work.  I don't want a dead rechargeable that has self-discharged or worse, a leaking alkaline.

That said, for my Legacy and DCS remotes, I use rechargeable NiMH.  For other household remotes, alkaline (get changed regularly).

Gerald, by any chance does your keyboard have a switch to select between rechargeable & alkaline?   The former are 1.2 volts and the latter 1.5.  As to your not having had problems with Duracell (alkaline?), nothing beats being lucky.  I refuse tobuy that brand except for 9-volt for smoke alarms.

Duracell batteries leak long before they're even remotely discharged, they're far and away the worst batteries for leaking I've ever used!

While they have a great shelf life, they don't work for all applications as they have a higher voltage.  Apparently, that causes some devices to quickly run them down.  I tried the Energizer Lithium in my Verizon FIOS TV controller, they were dead in weeks!  They also run down much faster in the DCS Remote than plain Energizer alkaline batteries, so clearly the higher voltage is an issue there as well.

Flashlights are an excellent place for Lithium, and all my flashlights have either rechargeable Lithium or Energizer Lithium.  My Legacy and DCS remotes are using Tenergy low self-discharge NiMh, they have worked out well.

RJR Thanks for the information ,i was going to order it & the shipping was  $ 7.00 ,so i decided i will take a ride to the store & get it ,it is only about 20 minutes away .Just for curiosity i checked to see when the last time i put these rechargeables in my living room TV remote & it was back on November 27  & still going strong ,so i think that the batteries are ok.

Not to hi-jack the thread, but Popular Mechanics has come out with a battery charger that re-charges disposable batteries ! - not just rechargeable ones. In other words, you can now recharge all the alkaline, NiCd and NiMh batteries you would ordinarily throw away (dispose of with your local recycler).

It works on all common size batteries and has a built in tester. It can also recharge them hundreds of times (depending on battery type). About the only caveat is that the batteries cannot be completely dead before re-charging. So when your computer or TV says your batteries are low, that's the time to recharge them.

It also comes with a couple of neat plastic cases that let you put a AA battery in them and convert them to C or D size batteries for temporary/emergency use.

Unless I'm missing something, this seems like a game changer.

FWIW, these have been around for decades, however their actual effectiveness is somewhat questionable.

True enough, but this is the first I have seen by a "reputable" name brand company. It's only been on the market for a couple of months and, hopefully, there's been advancements in new technology.

Obviously, Popular Mechanics is having the device manufactured by someone else, but the fact that they have put their name and reputation on it should raise the potential that it is effective.

I'll let everyone know.

There are dozens of testers on the market, some batteries even come packaged with their own tester.   However my way of testing was to go Lowes and purchase a large box of Energizer batteries then go to every device in the house removing Duracell aa/aaa batteries and tossing them in the trash.  With Duracell it's not a matter "if" they will leak, only a matter of time and that time could be only two weeks.    I've thrown away my last Duracell ruined flashlight, remote, radio, tester, tool, etc, etc, etc,...      Also the "Famous" Duracell guarantee and warranty,...     they pay by sending you a discount coupon for more Duracell batteries,...      which will NEVER be used.

I would be very wary of using a device to try to charge batteries not designed for recharging.  Could be hazardous. Seems to me that if you can afford the outrageous prices for O gauge locos & rolling stock, you should be able to afford tre difference in price between alkalines and rechargeables, which should be good for 10 years or so

We all have our own opinion as to which batteries will leak & which won't leak ,but i can only speak for myself about my experience ,as i have been using duracell ever since i got back into the hobby & that has been about 14 years without any leakage ,i would say that is a pretty good track record ,however until i figure out why my keyboard & mouse are going down so fast i will keep using the duracell batteries ,i just put two of them in my keyboard i will see if they last longer than the rechargeables .

True, but my opinion is based on multiple instances of fact, so that's not really just an opinion.   I have no idea how you made it 14 years, I never made it 14 months without a leaking incident!

Alkaline batteries are by far the worst to leak,  Period.  And it is not even close.  Next are normal zinc/carbon batteries.  NiMH are the least likely to leak and I have never had one leak, even after 10 years or so.  Alkaline batteries are by far the best in high drain uses.  But over months and even years of just setting around they will all leak given enough time.

It is a chemistry thing and alkaline batteries attack the steel battery jacket better than the other batteries chemistry.

The worst combination is an expensive Maglite flashlight, with aluminum cases, and alkaline batteries.  Alkyds will attack aluminum with vigor.  I will never use alkaline batteries in a Maglite flashlight anymore.  I have bought over 20 Maglite flashlights at garage sales, for little money, over the years (from 12 inches to 3 inches long) and have managed to ruin 3 or 4 with alkaline batteries.  I have tried to drill out the batteries with failure always resulting.  I use only zine/carbon in them now although the batteries expire out much faster with heavy or long usage.  Most flashlights just set around with batteries in them and if alkaline, they will most likely leak and ruin the flashlight or your remote, etc.

I’m wondering if some of the leakage problems had to do with counterfeits.

Counterfeit Duracell Coppertop AA / AAA Batteries | Consumer Alert (thecounterfeitreport.com)

I never gave much thought about what brand or type of battery to use, but after reading this thread, I’m going to look into it further before I buy any more batteries.  I found one site on the university of the internet that says zinc-carbons are the worst for leaks.

What are zinc-carbon batteries? – BatteryGuy.com Knowledge Base

Zinc-carbons soon leak after they go dead.  In middle of last century, Ray-o-Vac came out with steel encased zinc carbons that didn't leak for a long time after going dead.  Zinc carbons, including Ray-o-Vac damaged many Lionel F3 diesels when left inside the loco.  Back when Duracells were made by Mallory, they were excellent.  I do not think this is counterfeit batteries, because I would be fairly certain that Costco would take care, especially since they have direct agreement with Duracell to make Kirkland.

Last year I finally disposed of eight Ray-o-Vac fast rechargeable NiMHs that were over 15 years old.  I did get my money's worth
