So do yourself a favour and do it yourself. 1  Place a dead laptop battery in a completely sealed plastic bag. 2  Place the bag and battery in your freezer for between 11-14 hours. 3  Remove the bag from your freezer and allow the battery return to room temperature after taking it out of the bag, this is very important.
A fallow crop is a crop that you plant usually in the summer/fall and let it there to act as a green manure for the soil. You can harvest top growth for forage or feed but the vines and roots help build the soil tilth. If you leave the entire plant would then technically be called a cover crop, I think.
Tallow is a rendered form of beef or mutton fat, processed from suet. It is solid at room temperature. Unlike suet, tallow can be stored for extended periods without the need for refrigeration to prevent decomposition, provided it is kept in an airtight container to prevent oxidation. In industry, tallow is not strictly defined as beef or mutton fat. In this context, tallow is animal fat that conforms to certain technical criteria, including its melting point. It is common for commercial tallow to contain fat derived from other animals, such as lard from pigs, or even from plant sources.
