| Sometimes called the fourth stage, "equalizing is an overcharge performed after fully charging deep-cycle flooded/wet batteries. An equalizing charge prevents battery stratification and reduces sulfation which are leading causes of battery failure. Trojan recommends equalizing every 30 days or when batteries have a low specific gravity reading after fully charging... Deep-cycle AGM or gel batteries should NEVER be equalized."((http://www.trojanbattery.com/pdf/TrojanBattery_UsersGuide.pdf)) | Sometimes called the fourth stage, "equalizing is an overcharge performed after fully charging deep-cycle flooded/wet batteries.

| | House banks in rigs that are driven regularly are likely already mixed by jostling, so equalization may be less important. |

| Our theoretical T-105 bank will equalize at 16.2v. Since voltages are so high **it is common to disconnect everything else from the battery during equalization**; this prevents overvoltage damage to electronics. Overvolting electronics could be particularly expensive if the solar controller goes into equalization when [[electrical:12v:alternator|alternator charging]] is occuring -- the [[electrical:12v:intro|house]] and [[electrical:12v:chassis_power|chassis]] sytems are combined and overvoltage could be sent back to the vehicle. | Our theoretical T-105 bank will equalize at 16.2v.
