Old & Damage Lipo Safety Disposal

[wireframan]

Very informative. Before I'm afraid of dumping my damaged lipos to the bin. Now I know what to do.

Here's the video:

clear instructions

clear instructions. thanks.

save the dean plug, dont waste it

Just dump the batt into salt water?

I've read somewhere, perhaps here on this forum, that we also need to make a small slit to expose the cell (dangerous, i know, but that's what i read...)??

Usually,I cut off my deans to reuse it and then i dump it into a container full of salt water.I leave it overnight before i dump it into the central refuse center

[foxkilo]

Does it puff up after the salt water treatment?

Does it puff up after the salt water treatment?

Nope.

[vipermako]

may i know what is rationale behind putting it in salt water.
what is the chemical reaction involved or was it just to let the current discharge at a slow rate [ learned in school that salt water is conductive]

The last thing we need is to have someone who isn't aware of proper lipo disposal, throws it down the chute just like that

Can we have this as a sticky to raise lipo disposal awareness?

To dispose of LiPo cells and packs:

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.

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

2)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.

3)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.

4)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.

5)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.
