Will I damage my laptop battery if let's say I plug in my battery to my laptop while at the same time using my adapter to power my laptop?

Will my laptop battery get damaged due to overcharging ?

Reason is because in case of any black out, my laptop battery will be able to power my laptop if there is a power surge.

Please help

overcharging and heat from lappy can damage the battery...

after reading this...quickly i remove the batt...

is dat posible i buy new battery for my laptop..but hav long lasting life..3hour++

there's no such thing as overcharging... the laptop would cut off power to the battery once it's fully charged...

however, heat does kill the battery cells, best to remove it when using intensive programs like gamin...

new battery doesn't affected by that.

its highly depend on your usage, especially for new battery.

check your CPU usage level, brightness of LCD, those are the major factor.

let me put it this way:

you plug in your battery during DC supply, there is slight probability that your battery lifespan will decreasing by time.

you unplug your battery during DC, your battery lifespan might be a little longer, but you will face a risk of mobo damage due to sudden ceased of power supply.

which one do you prefer?

how long the battery can last depends on many factors...

capacity of the battery, program that u run, wear lvl of the battery, juz to name a few...

as a general guideline, expect around 3hrs from a new battery, ULV and netbooks excluded...

all i can say, those are total bullshit...

waste money la...selagi not rosak..use until rosak =D

why not? thats most common trick especially when you are traveling

dont worry much about your battery duration. just check your usage level and its can be control by that way.

wow astria having PMS today

too much studying perhaps???

i bought new laptop (well not new, just one month old) i never unplug battery .... at home always use wall plug.

after 1 year battery life decrease from 3 hour to 2 hour (best stretch) now after 3 years can last maybe 30 minutes ... lol. (already bought new battery now can last 3 hours++)

my friend who practice unplug the battery after 3 years also same condition as me ... can last maybe a little bit longer around 45 minutes ...

so up to you lah

I guess batteries degrades overtime as they age

+1
Better, just remove the battery when power supply is available

Now can last around 45 minutes only....
I don't think if always unplug the battery will shorten the lifespan of the batteries that quickly though...

there is one website named Battery University or somethin' that explain from A to Z in details about battery. i did bookmarked it before but don't know where the heck did i put it.

it should be an excellent references.

isn't that already stated in the law of life?

depends on how u treat the battery...

i ve yet to try the 40% + fridge technique...

all item in the world akan rosak jugak akhirnya..

Just plug in the battery, better battery damaged rather than data damaged....
