A: Yes. This battery is compatible with the standard E6430 and the slim “s” version (E6430s). However, please note that for some slim models, a 6-cell battery may protrude slightly from the bottom or back compared to a 3-cell version.
Q: Is this battery easy to install?
A: Extremely easy. This is an external-release battery. Just slide the locking tabs on the bottom of your laptop to pop out the old one and click the new one in—no tools or technical skills required.
