What are RAM or resume batteries?

Some notebook computers are designed with a dedicated battery for backing up RAM (random access memory) functions when the machine temporarily loses power from the main battery. This feature allows users to change the main battery pack without losing the current applications and settings residing in memory. This is called a “battery hot swap” – switching the main battery pack without having to turn off the computer. These type of batteries are alternately known as bridge batteries, RAM batteries, auxiliary batteries or resume batteries. Most RAM batteries are rechargeable NiCad or NiMH and will last around 2-3 years. It is recommended that you replace your notebook’s RAM battery when replacing the CMOS battery.
