AddOn Computer & Laptop Batteries

Save money on laptop replacements by pairing new computer and laptop batteries with older devices. Lithium ion design ensures long-lasting use, extending the lifespan of your portable devices. Find batteries specifically designed for your existing laptops, so they fit properly and work reliably.

Long Life
New computer and laptop batteries are tested and rated for up to 500 recharge cycles, ensuring you get plenty of use from each replacement. Find longer-life batteries designed to last many hours before needing to be recharged, or select standard models for devices that are frequently plugged in.

Top Brands
Find batteries for top computing brands, including HP, Lenovo, Toshiba, and Dell. Each battery is specially designed to fit a particular laptop model, so it fits correctly into the computer and works reliably once installed. These batteries are constructed with the same standards as the computers themselves, so you can be confident in their quality.

Easy Installation
No specialized skills or tools are needed to install replacement batteries. Simply remove the old, worn battery, and insert the new one in its place. Charge the battery with a compatible power adapter, and then simply boot up the laptop normally; no software updates are required. Your employees can perform these replacements themselves in mere moments, saving time for your IT staff.

Cost Effective
Replacing outdated computer equipment can be a significant expense. When a battery fails before it is necessary to replace the entire device, a new battery breathes fresh life into the unit, extending its working lifespan and saving you the expense and hassle of upgrading early.
