Pros

Great to be able to use my laptop as a laptop and not be tethered to the wall outlet any more. It holds the charges for a longtime and fully recharges quickly. Actually keeps the laptop cooler as it lifts the rear of the laptop about 1/8 higher off th... Read More

Day 1 countdown 6/12/20. Dtk continues to impress me with quality. Good packaging and feels like a quality product.

Cons

About 8 months in to owning the battery, it randomly fails! By december 2019, getting only about 45min runtime and the laptop reports anything from 3 to 75 mins. Item is junk, buyer beware!

When charge reaches 100%, battery begins discharging although ac is still connected. The laptop continues to run as the battery discharges. It just depends if the battery is charging or discharging. I have learned not to let it run so low that i lose ... Read More

When i remove the charger at 100%, it immediately reduces charge to 69%. Battery fits fine, but will not hold a charge. Only charged to 94%.

Quality

Bought this for my old laptop this works great as a replacement so far working good no issues

This battery works perfectly, and holds a normal operation charge.

I have bought non oem batteries in the past and most were not recognized by the charging unit or computer.

The battery life is wonderful too since to lasts for several hours before i have to plug it into the wall to charge it.

Price

Great price and perfect fit for laptop.

Super easy to install and a great price.

Was very sceptical due to the very low price.

But after seeing the price and trying it out for my self i can say for a fact this is a five star product.

Shipping

Shipping was quick and item was packed very securely.

Arrived very quickly and well packaged (to prevent damage).

Th product was what i expected & it arrived early.

The battery got to me within just a few days and was exactly what i needed!

Packaging/appearance

Good packaging and feels like a quality product.

Looks like it came new as part of the laptop.

Competitiveness

I highly recommend buying this battery for older dell laptops.

And due to its lower cost, it makes the best replacement battery for when the name brand dies.

I was sceptical at first, after all it was not name brand.

Dell has replacements for $100+ but our friends at amazon have these for less than $30.
