One thought regarding slightly different speeds, our trailer has a Charge Wizard for the battery. It operates at 3 slightly different voltages. This could have some affect on speed.
14.4 Volts – Rapidly brings the RV battery up to 90% of full charge.
13.6 Volts – Safely completes the charge.
13.2 Volts – Maintains charge with minimal gassing or water loss.
14.4 Volts – Every 21 hours for a period of 15 minutes prevents battery stratification & sulfation – the leading cause of battery failure.
