I've never met an alkaline battery that didn't leak on something important. Duracell is by far the worst, but now Energizer has jumped to the lead. I'm on the bandwagon with everyone else, Lithium primaries for the stuff that sits long term and not used much and Eneloops for the rest. Neither battery chemistry has ever leaked on me.

Make a note right now of a stored radio, flashlight, or important electronic device that you have not used this year. If it has alkalines in it, pull them out. If you don't, you are simply asking for trouble. You might get lucky, but the alkaline Russian roulette will eventually catch up with you.

Ditto,I used em early on,they sure arent eneloops and I have none left.

Great thread folks,thanks for all the great info,really appreciated!

Celler,is that a black GSD in avatar?

By "true D" cells, I don't think you mean I could place four of the Tenergy Lithium Thionyl Chloride D 3.6V's in my unmodified/standard 4D CCRadio2 or MagLite and would be good to go. To be clear, if you couldn't or shouldn’t, then they’re not equivalent or true.

Here's some footage of an open air lithium battery burn-off/explosion: http://www.youtube.com/watch?v=vS2hGoJVmlA .

Tenergy sells 1.2v LSD NiMH D cells with a rated capacity of 10 Ah. They also sell LSD NiMH C and 9v cells that work at ordinary NiMH voltages.

By "true" I meant that the D cell wasn't made of AA cells in parallel internally.

I don't know anything about their Lithium cells.

Dougs advice,the maha, gets excellent ratings too.Im sure from what folks say you will be MORE than happy with the maha.


I have the Maha unit. It now has one bay that is bad (several years of hard service) so I am looking for a replacement. 3v is not bad. I can make a DC power supply to feed it. Does it give the complete spec? as in 3vdc at 3a or something like that?

The Maha unit has a rather large back lit display that becomes a bother at night. We live much of the year in a pick-up camper and the Maha is too bright for even a night light. I end up putting something over the display. However I would like to have it mounted on a wall, so now covering the display becomes a "project".

I stand corrected.

Yes, that is Raven the black GSD. Ninety-five pounds of treat-begging, trespasser-chasing, any creak in the night amplifying deterrence. Love him.

Ah,then this is perfect for you as the display isnt lit.

Output 3volt,2.8 amp per wall wart.

What the heck,its really hard to go wrong for 28 bucks for a smart charger.

If you get one make sure its the BC700,the BC900 had serious overheating problems.

One 'glitch',a REALLY dead battery wont charge,it wont recognize it.But if you stick it on a cheapo dumb charger for one minute its enough for the BC700 to see it and away you go.
==============================
Celler,gotta love those GSD's for sure.Black GSD,BTDT!
==============================
Grady,thanks for the youtube vid,thats some lithium fire,wow!!!!!

I was in a battery factory last year that had a truck load of Li batteries spontaneously combust in the parking lot one night. Interesting story. The truck was just parked there overnight. The fie department had a heck of a time putting it out.

I think "low end bulk buy batteries" is the key here, not "cheap equipment". A battery can't tell what kind of device it's in. And the difference between, say, a steel contact and a gold plated one has to do with the resistance (electrical, not mechanical) that the battery must push against. High resistance contacts will deliver slightly less voltage to the device being powered. And will eat up a small amount of battery capacity and waste that as heat (but it's an infinitesimally small amount). That may affect efficiency of battery utilization, but the battery really doesn't care about that and won't leak just to spite you for not having gold plated contacts. Pairing dissimilar metals together can (but not always) have negative consequences (corrosion, etc.) but it's not like good equipment is made out of the same metals that batteries are (similar) and cheap equipment is made out of different metals (dissimilar).
