Lead-acid chemistries prefer light cycling and full recharge between those cycles. Infrequent excursions below the [[electrical:depth_of_discharge|50% depth of discharge]] norm will not cause much damage assuming a full charge is accomplished ASAP afterwards. | 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//. |

This article is about the intentional and chronic depletion of lead-acid banks below the 50% mark. | 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.((the high end of the acceptable Absorption range. Maybe even EQ)). Perhaps [[electrical:12v:eternal_absorption|forgoing Float altogether]]. This might be desirable when: |
