===== increasing effective Absorption duration ===== | |
| |
Deep cycling generally extends the amount of time for a battery to complete Absorption. At some you may run into the controller's maximum Absorption duration. While you may not be able to increase the //actual// duration,((as when the controller setpoint is maxxed out)) you can achieve a similar effect with one or more of these techniques: | |
| |
| |
* 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 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. | |
