Iv always wanted help with this - How does one dispose old/leaky batteries? Im not if favour of chucking it in the bin as it will just end up in a landfill or in fire. I do not throw my old batteries - 1.5v standard non-rechargable batteries used for clocks, tv remotes etc. I have kept them saftely in an airtight container with the hope that i can get rid of them in a responsible manner. How can i get rid of them?

i think you have tons of batteries now.

Haha yup i do have quite a number of 1.5v and 9v batteries.

Well, I am not sure how you could dispose em of. But you could make a Hydrogen peroxide rocket engine... MnO2 in the battery can be used as an oxidizer. Never tried it but it "may" work...  

I too have not come across any recyling or drop off location in India. The same manufacturers in US and Europe have a recycling programmes but dont know of any back here

Sigh... looks like im going to have to parcel them to the US

To dispose of LiPo cells and packs, this can be used for any battery. OR GO TO http://www.batteryrecycling.com

1. If any LiPo cell in the pack has been physically damaged, resulting in a swollen cell or a split or tear in a cell’s foil covering, do NOT discharge the battery. Jump to step 5.

2. Place the LiPo battery in a fireproof container or bucket of sand.

3. Connect the battery to a LiPo discharger. Set the discharge cutoff voltage to the lowest possible value. Set the discharge current to a C/10 value, with “C” being the capacity rating of the pack. For example, the “1C” rating for a 1200mAh battery is 1.2A, and that battery’s C/10 current value is (1.2A / 10) can be used, such as a power resistor or set of light bulbs as long as the discharge current doesn’t exceed the C/10 value and cause an overheating condition. For LiPo packs rated at 7.4V and 11.1V , connect a 150 ohm resistor with a power rating of 2 watts (commonly found at Radio Shack)to the pack’s positive and negative terminals to safely discharge connecting it to an ESC/ motor system and allowing the motor to run indefinitely until no power remains to further cause the system to function.

4. Discharge the battery until its voltage reaches 1.0V per cell or lower. For resistive load type discharges, discharge the battery for up to 24 hours.

5. Submerse the battery into bucket or tub of salt water. This container should have a lid, but it should not need to be air-tight. Prepare a plastic container (do not use metal) of cold water. And mix in 1/2 cup of salt per gallon of water. Drop the battery into the salt water. Allow the battery to remain in the tub of salt water for at least 2 weeks.

6.Remove the LiPo battery from the salt water, wrap it in newspaper or paper towels and place it in the normal trash. They are landfill safe.

Thanks for that. What about normal battries - everyday, duracell etc.

What is everyday? Or did u mean eveready?

If they are rechargable, then just discharge them completely and dispose them away into the recycle bin.
