Welcome to a Laptop Battery specialist of the Lenovo Laptop Battery
The X270 series comes in a wide variety of configurations, and only some of them are worth the money. The entry-level model with battery such as Lenovo 0A36305 Battery, Lenovo 45N1018 Battery, Lenovo 45N1019 Battery, Lenovo ThinkPad X220 Battery, Lenovo ThinkPad X220i Battery, Lenovo ThinkPad X230 Battery, Lenovo ThinkPad X230i Battery, Lenovo ThinkPad X230s Battery, Lenovo 01AV422 Battery, Lenovo 01AV425 Battery, Lenovo ThinkPad T560 Battery, Lenovo 01AV427 Battery starts at $881.10 and comes with an Intel Core i5-7200U, 4GB RAM, 500GB Hard Disk Drive, and a 12.5-inch (1366 x 768) display. That's not great: you can get the Dell Inspiron 13 7000 2-in-1 with 8GB RAM, 256GB SSD, and a 13.3-inch 1080p touchscreen for only $760.
If you're looking for a better processor or additional RAM, it's easy to customize your machine on the Lenovo website. But not all those upgrades are worth the money. Our test unit was customized as high as it will go, and would cost $2,028.60. Here are the specs for the version we reviewed:
•Intel Core i7-7600U
•16 GB RAM
•476GB SSD
•12.5-inch HD (1920 x 1080) matte display, non-touch
•USB-type C (supports USB 3.1 Gen 1 speeds)
•Full-sized USB 3.0 (x2)
•HDMI
•Ethernet
•Hot-swap battery system
The one we tested is a powerful machine and has phenomenal battery life, which is a rare combination. But I would opt for this configuration: Intel Core i5-7500U, 8GB RAM, 256GB SSD, 1080p display, and 72 watt-hour rear battery for $1,416.60.
All the models come with a 3-cell 23Wh internal battery. By default, the rear battery is also a 3-cell 23Wh unit. It only costs $5 to upgrade the rear battery to a 6-cell 42Wh unit, and $25 to get a bulkier 6-cell 72Wh rear battery. Either way, the battery upgrade is totally worth it, no matter what customization you decide to go with.
Most laptops have a single battery. They're usually located at the rear of the device and they may or may not be easily removable. Either way, even if you have a removable battery, swapping out for a freshly charged backup means shutting the whole system down. The X270 is unique because it comes with two batteries and you can "hot-swap" by removing the rear battery without turning the computer off.
The internal 3-cell battery, located at the front under the keyboard, keeps the computer running while you're swapping out the removable battery at the back. If your battery life is getting low, if you have a charged up battery in your bag, you can slide it into the rear of the machine like a jigsaw piece.
If you're looking for a portable powerhouse that will last you well into the night, then you can't get much better than this. This ThinkPad is one of the most travel-friendly machines out there. The hot-swap battery system, unique to the ThinkPad line, will sustain the machine for as long as you can keep the back-up batteries charged. It's also lightweight enough to slip in a bag, durable enough to survive a few bumps and bruises, and can be outfitted with an LTE modem for on the go Internet.
The top-end models are priced fairly, but the design doesn't make it feel like a premium machine. If you're going to go for a high-end laptop, I'd opt for a MacBook Pro, the Dell XPS 13, or even the Lenovo X1 Carbon. They're similarly powerful and have good battery life, even if they can't match the X270 with its unique hot-swapping battery system.
Speaking of the hot-swapping battery system, the default option on all Lenovo X270—even the $1,600+ models—is a 3-cell 23.2Wh rear battery, but you can upgrade to a 42Wh rear battery for $5 or a 72Wh rear battery for $25 and you should absolutely do that, otherwise you'll likely get mediocre battery life.
The sweet spot really lies somewhere in the middle. The $1,300 to $1,500 range is when you're getting the both of best worlds. The $1,300 to $1,500 range is where you'll find the best of both worlds, including a fast processor, plenty of storage, and unparalleled battery life. The X270 can't do anything about the guy in front of you reclining into your space the whole flight or the unruly child that's kicking the back of your seat, but at least you never have to worry about running out of juice.
