how long to charge a 12v deep cycle battery
For example, if a deep cycle battery's capacity is rated at 100 ampere hours (AH) at the 20 hour (C/20) rate, it will produce approximately 83 AH at the eight hour (C/8) rate, 63 A in two hours (C/2), and 55 AH in one hour (C/1). This is due to the Peukert Effect.or example, a 40 amp hour battery with a 5% discharge would require approximately two amps hours to be replaced. Using a five-amp charger, it would take approximately 24 minutes (2 amp hours/5 amps x 60 minutes) to recharge the battery. A 10-amp charger would take approximately half the time or 12 minutes.
