Abstract
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.

A moss guard for a lead-acid battery cell, the lead-acid battery cell having a plurality of positive electrodes, each comprising an upwardly extending positive lug, a positive strap connecting the positive lugs, a plurality of negative electrodes, the negative electrodes including top surfaces spaced from the positive strap, one positive electrode being between each adjacent pair of negative electrodes, the moss guard comprising:
- a body;
- and
- a plurality of fingers extending from a side of the body, the plurality of fingers configured to substantially cover the top surfaces of the negative electrodes between the negative electrodes and the positive strap, wherein an end of at least one of the plurality of fingers distal to the body comprises a lock, the lock being configured to resiliently deflect between an engaged position and a disengaged position and being configured to fix the moss guard with respect to the positive lugs in the engaged position.
A lead-acid battery cell comprising:
- an electrode assembly comprising:
- a plurality of positive electrodes, each comprising an upwardly extending positive lug;
- a positive strap connecting the positive lugs;
- a plurality of negative electrodes including top surfaces spaced from the positive strap, one positive electrode being between each adjacent pair of negative electrodes;
- and
- a separator between each adjacent positive electrode and negative electrode;
- an electrolyte;
- and
- a moss guard comprising:
- a body;
- and
- a plurality of fingers extending from a side of the body, the plurality of fingers configured to substantially cover the top surfaces of the negative electrodes between the negative electrodes and the positive strap, wherein an end of at least one of the plurality of fingers distal to the body comprises a lock, the lock being configured to resiliently deflect between an engaged position and a disengaged position and being configured to fix the moss guard with respect to the positive lugs in the engaged position.
