however, when battery charging current is < 2 amps while on float charge.

(c)

A battery charging current of < 2 amps when on float charge is acceptable for meeting specific gravity limits following a battery

recharge, for a maximum of 7 days.

When charging current is used to satisfy specific gravity requirements, specific gravity of each connected cell shall be measured prior to expiration of the 7 day allowance.
