ASUNCELL New Laptop Battery for Dell Latitude E6400 E6410 E6500 E6510 Precision M2400 M4400 M4500 M6500

I have an ancient Dell E6400 laptop that is only used to maintain my financial records. The battery died several years ago and I have only been using it while plugged in. Came upon this replacement battery and decided to give it a try given its very reasonable price (I could not even find an original Dell replacement on the Dell website as this is such an old model). This replacement battery was truly a “drop in” replacement (there are two “clips” that release/hold the battery in place without the need to unscrew anything and so replacement took perhaps 2 seconds to complete). Although not shown in the product photo page, the base of the battery also has a button and led charge indicator lights just like the OEM Dell battery. After following the provided instructions to drain the battery to 2% upon its first use prior to charging it, the battery seems to be holding its charge well. Using a 90W Dell compatible charger (19.5V output), the battery charged quickly from 2% to 90% in under 2 hours. As this laptop is truly ancient in computer years, I was able to get about 2 1/2 - 3 hours of use out of a fully charged battery, which was comparable to my original Dell battery when it was new IIRC. The true test will be whether this continues to hold a charge after repeated cycling. For now, 5 stars.

The battery worked/charged great with my HP laptop.

It fit fine and seems to be holding a charge well.

Works well , good price !!

Fit perfect and had charge when I got it. Works great

My battery was on it's last leg... it came quick, works like it supposed to. No issues.

So far it has worked well. It has been 5 days. Liking it up to this ppoint.

I powered up the laptop with a full battery no more than 10 minutes ago, and the charge plummeted from 100 to 89 percent. This doesn't even last 30 minutes before shutting down without warning. Seriously, consider returning this battery and trying another brand.UPDATE: The battery was purchased in January. It is now June, and the battery is randomly shutting down on me when there is less than 30% left.No worth the money even if it was sold at 10 dollars.
