12. Typical Notebook Batteries
The following pictures show typical form factors that you will find used in most notebooks. Each of these batteries is comprised of multiple individual cells.
A standard battery from a Gigabyte widescreen notebook. This battery delivers total energy output of 65 Wh.
Gateway's M460XLb Notebook includes a 12-cell battery that delivers total energy output of 95 Wh.
HP offers a 5eight Wh supplementary battery that fastens beneath a notebook PC.
Various notebook vendors offer optional double-capacity batteries, that also normally stick out well past the rear edge of the notebook itself.
A second 48 Wh battery can be inserted in the optical drive bay in a Dell Latitude D610.

"Better still, Li-Ion batteries exhibit none of the memory effects associated with the other two types just named."
Neither do NiCad or NiMH batteries, of course, unless you're using them in a geosync satellite power system. With a charging system as smart as the one required for Li-ion or Li-polymer, NiMH batteries don't suffer from overcharge and the resulting voltage depression (what's generally mistaken for a "memory effect" in the association cited). I wouldn't be surprised to see some notebooks returning to NiMH, albeit the new low self-discharge types.
