BTP-35A1 Acer TravelMate 520/530 Series Battery 4400mAh

Stay mobile with a long life Lithium based Notebook Battery. Lithium-Ion and Lithium Polymer batteries typically last longer than most other batteries, so they do not require replacement as often. Many of our batteries have internal circuit boards that are used communicate battery performance, temperature and voltage to your Laptop computer. This feature allows your Notebook to more accurately communicate information like "remaining runtime" to you through the battery status lights and/or fuel gauge. Our batteries are manufactured and tested to ensure that they equal or exceed your Notebook's Original Equipment. And, whether you travel around the world or from your office to your home, maintain uninterrupted work cycles by taking a spare battery with you.

Note: The actual life of the Laptop Battery may vary depending on which applications are used, which power management settings are in force, which hardware features are utilized. Recharge time varies depending on usage. Depending on the specific laptop model, some batteries may not charge while the notebook is consuming full power.
