Welcome to a Biomedical Battery specialist of the DELL Laptop Battery
A great ultraportable business notebook needs several key components, including speed, security, durability and endurance. The 12-inch Dell Latitude 7280 (tested at $1,830; starting at $1,029) has all of the above, thanks to its 7th-generation Intel Core i7 processor and impressive battery life with battey like DELL 34GKR Battery, DELL F38HT Battery, DELL G95J5 Battery, DELL 451-BBFY Battery, DELL PFXCR Battery, DELL T19VW Battery, DELL 909H5 Battery, DELL 451-BBFV Battery, DELL Latitude E7440 Battery, DELL Latitude E7420 Battery, DELL 3RNFD Battery, DELL Latitude E7450 Battery . Plus, this lightweight system is built to survive short drops.
The Latitude 7280's black magnesium-alloy chassis is thin and nondescript, with a glowing-white power-indicator light on the front edge. The soft-touch paint used on the lid and deck gives the chassis a good feel and makes it easy to grip.
Dell placed the Latitude's HDMI port, a USB 3.0 port, an optional smart-card reader and an optional Thunderbolt 3 USB Type-C port on the left side of the notebook. The laptop's headphone jack, SD memory reader, headphone jack and Ethernet port are on its right side.
Our test unit included a manufacturing problem we've seen before in other laptops: Its underside was unbalanced, with the bottom-right corner not lying flush when on a table. When placing my wrists on the deck to type, I noticed the right corner moved down and touched the table underneath, repositioning the far-left corner in the air. When Dell shipped us a replacement unit, we noticed the same issue, but to a lesser degree that we may not have noticed had it not been for the first unit.
I highly recommend you invest an additional $42 on the optional four-cell battery. If you do, you can leave the Latitude 7280's power cable at home, as the notebook lasted 12 hours and 29 minutes on the Laptop Mag Battery Test (continuous web surfing over Wi-Fi). That beats the times posted by the EliteBook (9:23), the three-cell version of the ThinkPad (8:16) and the average for ultraportable notebooks (8:10). Only the ThinkPad, with its optional six-cell battery, lasted longer, at an incredible 17:14.
We reviewed a customization of the Core i7-7600U model that starts at $1,619 and includes vPro technology and the six-cell battery. A model upgraded with a 256GB SSD, a 1080p display with an IR camera, a fingerprint reader, a smart-card reader and contactless a smart-card reader costs $1,830.
The $1,029 entry-level Latitude 7280 sports a Core i3-7100U processor, 4GB of RAM, a 128GB SSD, a 1366 x 768 display and a three-cell, 42-Wh battery. The Core i5-7200 CPU model of the system costs $1,169 and includes 4GB of RAM, a 128GB SSD and a 1366 x 768-pixel display.
The Dell Latitude 7280 packs speedy performance, a bright display and fantastic battery life into a thin, light design that's easy to carry. However, the screen isn't as colorful as we'd like, and the price can get pretty high, depending on which configuration you choose.
