1

Battery voltages below 8.7V may result in <3.0A current limit because of fold-back current limit.

2

VRLA battery manufacturers state that “heat kills batteries” and recommend operating batteries ≤50°C.

3

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.

4

Impulse type changes in current may have an average current error of ±(10% of reading + 2 mA).

5

1.0V negative off set is worst-case due to reversal protection diode on input. Typical diode drop is 0.35V.

6

2.0V negative off set is worst-case due to two series diodes in AC full-bridge. Typical diode drops are 0.35V each for 0.7V total.
