the battery does not last the expected one complete hour, but only 30 minutes,
giving an actual available capacity of only 50%.
Rated

capacity
20 Ah 40 A (2 CA) 5 Ah (25%)
20 Ah 20 A (1 CA) 10 Ah (50%)
20 Ah 12 A (0.6 CA) 12 Ah (60%)
20 Ah 8 A (0.4 CA) 15 Ah (75%)
20 Ah 1 A (0.05 CA) 20 Ah (100%)
Notes:
1. Dynamic Controls recommends to use batteries with a
capacity that is
at least twice as high as the average
discharge current.
2. New batteries often start with only 80% of their rated capacity.
After a few charging cycles the capacity will increase to 100%.
3. Deep discharging or overcharging dramatically decreases the
capacity of the battery. This damage is permanent, the battery
will never return to its original capacity.
