"Normal maximum" indicates the maximum power and current under normal
conditions with heavy drive activity occurring.
2
"Peak maximum" indicates the maximum power and current under peak
conditions with heavy drive activity occurring. With the EF51R and EF52R,
peak power occurs during the first half hour of fast charge after full discharge.
With the EF53, peak power occurs during self-test, which happens during the
first two minutes of operation.
