Leaving a lead-acid battery in a discharged state for
prolonged periods of time results in the undesirable growth
of large sulfate crystals (sulfation) that are detrimental to
battery performance.
VRLA batteries self-discharge at approximately 3% of rated capacity per
month at room temperature

. A 3% of rated capacity per month self-discharge
results in 100% discharge in approximately 33 months (
≈
3 years) for a battery
stored at room temperature. Self-discharge increasing with increasing storage
temperature.
Periodic recharging of stored batteries every few months is
recommended to prevent irreversible sulfation due to prolonged
time in a discharged state.
3. QuickStart
The PS150/CH150 modules are designed to handle extreme conditions. The
modules have been designed with mounting holes on one inch centers for
mounting to a standard Campbell Scientific enclosure back plate — see the
enclosure manual for mounting suggestions. See FIGURE
3-1
through
FIGURE
3-3
for typical enclosure installations using a PS150/CH150.
