What is Sealed lead acid battery?
[[File:Lead acid cell.svg|thumb|Sealed lead acid battery]] A '''sealed lead acid battery''' or '''gel cell''' is a [[lead acid battery]] that has the [[sulfuric acid]] [[electrolyte]] [[coagulation|coagulated]] (thickened) so it cannot spill out. They are partially sealed, but have vents in case gases are accidentally released for example by overcharging. They can be used for smaller applications where they are turned up side down. They are more expensive than normal lead acid batteries, but they are also safer. They use different chemicals than [[dry cell]]s, so they are [[rechargeable battery|rechargeable]]. ==Related pages== *[[Battery]] *[[Lead acid battery]] *[[Table of batteries]] {{science-stub}} [[Category:Batteries]]
