Simple Guidelines to Prolong Lithium-ion Batteries. 1  Do not discharge Li-ion too low; charge more often. 2  A random or partial charge is fine. 3  Limit the time the battery resides at 4.20/cell (full charge), especially if warm.  Moderate the charge current to between 0.5C and 0.8C for cobalt-based lithium-ion.
0. advantages of algorithm. 1  it is a step-by-step rep. of a solution to a given prblem ,which is very easy to understand. 2  it has got a definite procedure.3  it easy to first develope an algorithm,&then convert it into a flowchart &then into a computer program. 4  it is independent of programming language. it is a step-by-step rep. of a solution to a given prblem ,which is very easy to understand. 2  it has got a definite procedure. 3  it easy to first develope an algorithm,&then convert it into a flowchart &then into a computer program. 4  it is independent of programming language.
The discovery of enzymes that could cut and paste DNA made genetic engineering possible. These enzymes, restriction enzymes, are found naturally in bacteria, can be used to cut DNA fragments at specific sequences, while another enzyme, DNA ligase, can attach or rejoin DNA fragments with complementary ends.
