Battery problem .

[lambcrazy]

Hello friends , I red it online that if you want to have a good battery life for your laptop battery then you must full recharge and discharge it . But , my friend bought a new laptop and its battery discharges quickly . We also replaced it but we are facing the same problem ,So, p;lease suggeat us a solution and tell us how to increase a battery life ?

As such problems are hardware and usage dependent, best that you put the question to the manufacturer or a service representative.

#1 rule of thumb if you can: don't buy replacement batteries on the cheap. Get from original manufacturer if you can. Avoid ebay, etc.

#2 rule of thumb: don't partially discharge batteries frequently.

#3 rule of thumb: train your battery by draining it fully at least somewhat regularly. This helps the system know how long the battery can last. Let your laptop totally run the battery down, and do NOT let it go into standby.

I found this interesting articles about ipad battery life, more or less it is similar for notebook. www.apple.com/batteries/ipad.html

rule of thumb...

Rules of thumb from a decade ago are difficult to apply today, with the new battery technology available. I'll go along with rule #1, as this is a no-brainer. You get what you pay for. This will never change.

Rule #2 applied to older laptops, but newer ones have 'memoryless' batteries and function fine on frequent partial discharges.

Rule #3 as mentioned above, batteries don't need to be trained anymore. They just need sufficient charging time each time they're plugged in. Frequent partial charges can harm the battery. If we examine manufacturer recommendations, we will NOT run our battery down. This will harm it more than anything, and will drastically shorten its life.

Straight from apple:

"Apple recommends charging and discharging its battery at least once per month."

By discharging I doubt they mean 'run it down'. They simply mean, 'use it periodically' to keep the chemistry alive.

Fair point.

Optimal setting for constant use is not fully charged and not fully run down. 50% on average.

"Conversely, if you store it fully charged for an extended period of time, the battery may experience some loss of battery capacity, meaning it will have a shorter life."

By 'extended period of time' we would be looking at six months on the outside. Doubtful anyone is going to be without the laptop/tablet for that length of time.
