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.

* if duration setpoint is maxxed then **set Vfloat == Vabs**. Absorption duration will effectively be "until the sun goes down". | * if duration setpoint is maxxed then [[electrical:12v:eternal_absorption|set Vfloat == Vabs]]. Absorption duration will effectively be "until the sun goes down". |
* **charge at a lower current** (charging minimum). While [[opinion:frater_secessus:charging_faster|overall charging will take about the same amount of time]], Bulk's share of that time will increase and [[electrical:12v:charging#absorption|Absorption will take somewhat less time]]. | * **charge at a lower current** (charging minimum).

* **charge at a higher voltage** (Vabs), this will decrease Absorption duration. Keep a close watch on water levels for flooded batts, and also mind the max allowable voltage for AGM/Gel. | * **charge at a higher voltage** (Vabs), this will decrease Absorption duration.
