 Note that the **using 2x the charging current only sped up the whole process by 12 minutes (3.6%)** due to Vabs starting earlier but taking longer. Getting to Vabs faster could be [[electrical:solar:pwm_tweaking|preferable on PWM controllers]].  Note that the **using 2x the charging current only sped up the whole process by 12 minutes (3.6%)** due to Vabs starting earlier but taking longer.

 +Also note that for simple, timer-based Absorption configurations((like 180 minutes)) the slower charging regiment would actually complete more Absorption.((180/266mins rather than 180/310mins))
