A moss guard for a lead-acid battery cell includes a body and a plurality of fingers extending from a side of the body. The plurality of fingers are configured to substantially cover the top surfaces of negative electrodes between the negative electrodes and a positive strap. An end of at least one of the plurality of fingers distal to the body includes a lock, and the lock is configured to resiliently deflect between an engaged position and a disengaged position. The lock is configured to fix the moss guard with respect to positive lugs while in the engaged position.
