i have a dell laptop it is pretty old my brother has been using it for 3 years and now im using it we have changed the battery 2 months ago and so did the charger and from a afew days my laptop is turning off on 40-50% battery without any warning so please tell me what to do
 
Solution
A *healthy* battery should run the laptop at full power settings until a very low %. I've got one that powers a 45W i7 without issue, and another that powers a ULV i5 without issue despite being several years old. The one in my Dell would often cut off in 3-5 minutes near the end of its life (it's 7 years old and on the original battery).

The cells in this replacement one he got just aren't holding or are capable of outputting the required amperage to keep the thing running. There are some good aftermarket or refurbished batteries out there, and there are some that aren't worth your money. I think this was one of the latter and should be returned for a refund if possible an exchanged for something of higher build/cell quality.

Try to run it down as much as possible with the system idle. Plug in, recharge fully, repeat.

This should let the battery "learn" how much it's supposed to hold.

Sounds like your battery (probably not an OEM replacement) isn't able to provide full capacity under load once it discharges slightly. You can limit CPU power in Windows power settings to only use 50-70% of CPU power available to it, which on some computers, will make the battery last longer.

hi dudeman509, can it be cause of my storage because my C drive is almost full only 2 GB is free can it be the cause? because i downloaded a game few days earlier that got the storage almost full.

 
No, the issue with storage will not effect the battery.

Candydot is correct.

Run the battery down to flat ... charge it ... run it down agin.

If each time you do this the battery full level is higher then the battery is getting conditioned and properly charged.

but when i turn my laptop on again after it has shut down(due to the issue) the battery storage is the same as it has turned off when i plug the charger in, it doesn't start charging from the beginning

Yep. Hence why I said to run it down with as low load as possible.

Long story short it's just a defective battery. You can sometimes nurse it back to behaving, sometimes not.

It has nothing to do with the hard disk being full, but that will slow down your system otherwise.

If the battery has any kind of warranty policy on it, return it.

If it doesn't...you're out of luck and need to look around for a more reputable rebuilder/refurbisher. There are usually reviews on most of them.

Well obviously it isn't.

It's not the computer, it's the battery.

Which is exactly why the battery is defective. The cells are maintaining voltage but are failing to provide the necessary amperage to keep it running at the power level that the system is demanding. More or less like an old car battery that cranks fine, then refuses to do so again.
