How long should my Laptop battery last?

I purhcased a dell Inspiron a few days ago. The battery charges in about 2 hours, but then dies after i use it for 2 - 2.5 hours. Is this normal? The only discription on the site as to which battery is a Lithium-ion type, but it does not go into specifics on how many hours it should work.

If you are running alot of programms and your screan brightness is on full your laptop battery will die fast.
try running one or two programms at a time. this will lenthen your battery time. plus dont leave it charging all the time this will ruin your battery.

Yep that's about right.....you can lengthen how long it will last by turning the brightness of your screen down. you can also dish out a good chunk of money and buy a battery that will last about 4 hours.

Hi. i got a dell inspiron n4010 laptop. my battery backup suddenly dropped to half. i bought the laptop just 25 days ago. what may be its cause?


I am glad to HELP YOU!

The problem that are you describing here occurs many times - even for the BRAND NEW laptops!
The RAPID DRAINAGE of the batteries can have multiple causes:
# a defective battery
# the humidity of the storage place
# a bad connector
and so on.
What I'd suggest you is to take back your machine to the store and to ask for a BATTERY REPLACEMENT. I assume that if you said you've bought your Dell 25 days ago it should be under some WARRANTY CONDITIONS...
The next battery you will gt do like this:
# attach the battery into its slot
# make sure your Dell machine is OFF
# connect the AC power supply into the wall plug
# with the machine still OFF let the battery fully charge for AT LEAST 16 HOURS.

My best regards!
... and don't forget to RATE, please...

Yep, Id get another battery if I was you. I bet it runs down pretty fast too. sounds like one of the cells in the battery is dying.
Now if this is a new generic battery off ebay or an Amazon type store then those typically dont last very long so it could still be a dead cell. To get a good as OEM battery you usually either need to spend the bucks or rebuild it yourself. I dont suggest trying to do that unless you are really into electronics and soldering etc.

My laptop is dell inspiron 1501 but no work keybord and battery charging but supply line(AC adaptor) is ok.


Hello there. The Inspiron 1510 was released almost 5 years ago. If your system is more than 2 years old, then perhaps you will have to replace the battery. Battery for the most part, will only last 1 to 2 years. As for the battery, try connecting an external USB keyboard. If its working, then you need to replace the laptop's keyboard. Hope this will help.

Battery Not Identified.


hello

I suggest you a few steps to solve your problem.
  • remove the charger and press the power button till all residue power is radiated.
  • then connect the charger and charge the battery fully and try booting the system.
  • if this don't work check the output of your charger and see if it is working fine.
  • if it is working fine then remove the battery and connect the charger and try starting the system.
  • if it works then there are two things possible.
  1. battery gone.
  2. IC responsible for charging is gone.
i hope you can figure out the problem through this.

Thank you

Dell Inspiron E1505 won't recognize new battery


It won't charge or work correctly if it's not the correct one and of the right voltage etc.I don't know how the battery even went in if it's not the Dell specified battery.If it went in and looked to fit maybe the battery itself is bad but its hard to say.

Dell Inspiron 6400 Battery


your miracle,most laptop batteries have a life span of 4 years tops,but that if you take care of it,but most dont realize over charging kills the cells in your battery,and if you have it plugged up make sure you go into power settings and put it on ac/dc power settings.and if you have it away from home without power,put it on best battery settings,and let the power die all the way down before recharging,that will give it a full charge lasting longer.but as for your battery it might be time for a new one
