Lead-acid chemistries prefer light cycling and full recharge between those cycles. Lead-acid batteries are traditional cycled to [[electrical:depth_of_discharge|50% depth of discharge]] because it offers a balance between duty life (years between failure) and bank size.(("dead lead")) Pulling the bank below 50% DoD in emergnecies will not automatically cause damage //assuming a full charge is accomplished ASAP//. | Lead-acid chemistries prefer light cycling and full recharge between those cycles.

This article is about the intentional and chronic depletion of lead-acid banks below the 50% mark, **followed by vigorous recharging**. This might be desirable when: | This article is about the intentional severe use of lead-acid banks by running them below the 50% mark, **followed by vigorous recharging** at maximal voltage.

* get power back into the battery ASAP after deep discharge; drive for [[electrical:12v:alternator|alternator charging]] or run a [[electrical:generator|generator]] to get bulk stage going.
