Should I buy genuine Packed and new Li Ion battery with 1.5 years old manufacturing date? Will it die soon?. Are You mam & sir has that kind of inquiry?, If do then plz read the best solution below:

Hi, thanks for A2A.

It is tricky to answer for me to buy that battery.

The point here I mentioned above because of the phenomena called ‘ Over discharge’.

Basically Rechargeable battery exhibits self discharge either it is in use or not in use. Self discharge occurs due to internal chemical reactions happening inside of the battery. The amount of self discharge depends on primary cells, chemistry inside of the battery and temperature conditions.

This self discharge rate is varying in different batteries.

  • Lead Acid 4% to 6% per month
  • Nickel Cadmium 15% to 20% per month
  • Nickel Metal Hydride 30% per month
  • Lithium 2% to 3% per month

Self discharge’s primary cause is battery’s internal resistance. Internal resistance directly proportional to self discharge. Li-ion batteries are the one which has less internal resistance so that it has low self discharge rate. Li-ion batteries will have 5% of self discharge from 100% within 24 hours and lose 2 or 3% thereafter per month. Inbuilt circuit protection will increase this rate upto 5% per month. This discharge rate is almost constant for successive months. Sometimes temperature conditions of the battery environment will cause self discharge rate get increased. So keeping Li-ion battery between 30 to 40% even it is in idle state is recommended to be used for next time.

Overdischarge is the phenomena which may permanently damage the battery. What it means that, each cell in battery has predefined value or threshold level. When discharge rate of battery reaches this level, battery will cut off. For example, Li-ion battery will have cut off level of 3V/cell. After this cut off, if self discharge continuous, then it leads to overdischarge which ultimately damage the capacity of battery, irreversible reactions in solutions used in battery and increase inner built pressure in the battery. If this over discharge persists, you cannot recover it.

So it is safe that, approaching authorized samsung service centers for buying that battery. They keep original battery product.

Hope it helps!

We at this techno blog hope if those answers above can fix your problem. Thank You
