a
VRLA battery manufacturers state that “heat kills batteries” and recommend operating batteries at temperatures
below 50 °C.
b
Battery voltages below 8.7 V may result in <3.0 A current limit because of fold-back current limit.
c
Two-step temperature compensated constant-voltage charging for valve-regulated lead-acid batteries. Cycle and
float charging voltage parameters are programmable with the default values listed.
d
Impulse-type changes in current may have an average current measurement error of ±(10% of r 2 mA).
