RECHARGE TIME
RECHARGE TIME (Example assuming 100% discharge - 10.5 volts)
AMPERAGE APROXIMATE TIME TO 90% CHARGE
Type 4,2 Type 5,5
100 amps 35 minutes 52 minutes
50 amps 75 minutes 112 minutes
25 amps 140 minutes 210 minutes
Recharge time will vary according to temperature and charger
characteristics. When using Constant Voltage chargers, current
will taper down as the battery becomes recharged.
When current drops below 1 amp, the battery will be close to a
full state of charge.
CYCLIC APPLICATION OR STRING SERIES APPLICATIONS
Constant Voltage with Constant Current finish (CC/CV): 14.7
volts, temperature < 50°C, no current limits. When current falls
below 1 amp, finish with 3 amps constant current for 1 hour for
type 5,5 and 2 amps for all other types.
(All charge recommendations assume an average room temperature of 25°C)
