For any Category A parameter(s) outside the limit(s) shown, the battery may be considered OPERABLE provided that within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> all the Category B measurements are taken and found to be within their allowable values, and equalizing charge is started.

All Category A and B parameter(s) must be restored to within limits within the next 6 days.

For any Category B parameter(s) outside the limit(s) shown, the battery may be considered OPERABLE provided that the Category B parameters are within their allowable values, and equalizing charge is started.

All Category B parameter(s) must be restored to within limits within 7 days.

Any Category B parameter not within its allowable value indicates an inoperable battery.

Corrected for electrolyte temperature and level.

Or battery charging current is less than 2 amps when on charge.

Corrected for average electrolyte temperature.
