Putting the battery in freezer
-
be careful !!! high temperature variations are generally bad for such power suppliers... putting your battery in the fresher environment (refrigerator / freezer) is a know chemical phenomenon, but if you let it too much there, it will better the life of you battery at start, and simply kill it then... why do you think cars batteries are emptying themselves when winter's hard ?

What was the magic trick again? Plastic bag, freezer, lots of ice, 2 olives and shaken, not stirred? cheers, Chris Maunder

Put the battery in the freezer for 24 hours, take it out and recharge it, thats all there is to it :) - Anders

I always thought that was because: a) a colder engine takes more effort to turn over (the oil etc is less viscous at low temperatures), and so starting drains the battery more compared to summer. b) you tend to drive around with the headlights on much more, so the battery doesn't recharge as quickly, since the alternator is supplying power to the lights as well.

i was more talking about when you park your car for, say, 2 week under -10°... your battery will be empty when trying to start it again, even when you haven't drive it. for your thoughts, oil viscosity don't directly affect the battery charge. maybe at startup, but is you use a powermeter on your battery, you'll see that it's loosing tension. same with the lights...

When my batteries go flat, I put them in the microwave. It doesn't extend their lives, but the gratification is almost immediate.:-O "...a photo album is like Life, but flat and stuck to pages." - Shog9

I'm going to try that! My laptop battery is all but worthless now. It lasts maybe 5 minutes before dying.

Here is the complete recipe: Ingredients: Battery A bottle of wine 2 cups of milk Ziploc Plastic bags One Tablespoon Cashews or Almonds 1/4 cups raisins 1/4 cup sugar Recipe: 1. Discharge the battery as much as you can 2. Blend the milk, cashews and raisins with the sugar in a blender 3. Cover the battery in a ziploc bag make sure that there are no leaks 4. Put the blended milk in a different container 5. Put the ziploc bag and the milk in the freezer 6. Chill them both for 24 hours 7. Remove the the ziploc bag from the freezer and let it come to the room temperature 8. Remove the frozen milk from the freezer and pour a little wine over it 9. Put the battery back in the laptop 10. Celebrate the longlife of the battery with the frozen milk desert.

Careful though because this doesn't work for all battery types, it damages the chemistry in the battery. The latest generation Lithium-ion batteries this might work best but for Nimh I believe it is the worst thing. It is a good way of reviving cellphones and cordless phones as well. A programmer with a dream can accomplish anything. So, start by implementing your castle in the clouds and then working on its interface to a foundation :-D Quote by: Jeremy Pemberton-Pigott

>> for Nimh I believe it is the worst thing << Googling << NIMH FREEZER >>, the first few links seem to find it an effective practice. OK, as a programmer I am slightly perfectionist, so I have been sticking MY NIMH's inside a Pelican-case with one of the Peli desiccant bars, and only in the fridge at 40F or so. So far so good per my experience..... pg--az

I thought it was the other way around? Anna :rose: Currently working mostly on: Visual Lint :cool: Anna's Place | Tears and Laughter "Be yourself - not what others think you should be" - Marcia Graesch "Anna's just a sexy-looking lesbian tart" - A friend, trying to wind me up. It didn't work.

My mistake, I thought that I had remembered from my Chem guru friend which battery wasn't a good one to store in freezer.

I thought it was because chemical processes work slower in the cold. Isn't a freezer a prefered long term storage for batteries?
