## Description

Suggestion 1.For use a new battery, you’d better try a few cycles of discharging to 5%, then charging up to 95%. 2.Do not always run out of a battery to 0%, this would make it damage or usage life shortened. 3.Do not put away a battery for a long time (more than 2 months), this would cause cells inside of a battery losing balance. The battery will not be charged up again or its lasting time shortens, so do charge a battery at least one time within two months.

    Worthless
  

*by A***Y on Reviewed in the United States on November 22, 2019*

Installed the battery. Charged it up. Unplugged the power supply while using the laptop. Used the laptop for about 20 minutes and then the laptop just died. No warning at all.Plugged it back it and charged it all the way up again. Unplugged and used it for about 30 minutes down to about 50% and the computer just shut off again.Left the laptop off, and plugged it in for a couple hours. Unplugged and tried to boot the laptop up on battery alone. The laptop got partially through boot up and just shut off completely. Happened twice.Now the battery won’t charge at all.Complete waste of time and money. Tried to save some $ on an older laptop. I should have just bought an OEM battery.

    Fixed my problem
  

*by J***M on Reviewed in the United States on January 19, 2021*

Older, refurbed laptop and I was having trouble updating the BIOS because I kept getting an error stating that the device needed to be plugged in (it was) and the battery needed to be above 15% (it was full at 100%).  Did some hardware tests and determined that there was an issue with the battery.  Installed this, charged up, BIOS updated no problem (and helped also resolved my overly-active fan as well).Have yet to test the life span, as the laptop is always plugged in.  Will update once we see how long it lasts.  Only real gripe is that it fit, but JUST barely.  Needed a little extra shimmy to make it fit just right.

    Works very well!
  

*by W***L on Reviewed in the United States on June 1, 2018*

My battery for my Dell M4600 was effectively dead.  Would not keep a charge overnight and if unplugged after charging all night would only last long enough t boot up and use my computer for 10-15 minutes.  After thoroughly reviewing the offerings on Amazon, I chose this battery and am very impressed.  Arrived with about a 65% charge, kept running and kept an eye on the charge to get down to the 10-15% range, shut down and plugged in the power supply.  came back the next morning, booted up, 100%.  unplugged the power supply and used the computer for almost 4 hours on battery.  Arguably better than the Dell battery when the laptop was new.  I've been using it for about a week with no problems.
