the advantages of lithium batteries compared with nickel-cadmium- batteries

Lithium-Ion batteries are recent products compared to Lead batteries. They have been on the market since the 1980s. Lithium-ion technology has been proven to power electronic products such as telephones and laptops as well as cordless hand tools.

so this is the main advantages of lithium ?

05 advantage comparing with Ni-Cd

ð  Better weight / power ratio

ð  No memory effect

ð   No "lazy battery" effect

ð   Very low self-discharge

ð  Full of energy until the end

--------------------------------------------------------------------------------------------

1-  Better weight / power ratio

   3,6 V / 1,5 Ah    

2- No memory effect : 

What is the memory effect:

The principle is that when you recharge a battery without ever letting it discharge completely, you end up losing the unused capacity.

3- No "lazy battery" effect

New Ni-xx batteries cannot be fully charged when starting to use.

They need training to benefit from the full capacity. That’s why you have to load and unload them 3 to 5 times to overcome this.

Some users believe this is a quality issue. However, this is a technical characteristic of Ni-xx batteries.

4- Very low self-discharge

5- Full of energy until the end
