Battery mossing refers to the build-up of impurities on the top edges of battery element plates. Mossing occurs in all lead-acid batteries, usually at a very slow rate over a period of several years. The mossing may eventually result in short circuits between the plates. Severe battery mossing may cause a short between the elements and the plate strap. Mossing is exacerbated by overcharging, by rough handling, or due to normal motion and vibration when installed in mobile equipment.
To help solve this problem, battery manufacturers install a thin plastic shield on the top of the battery plates. In the industry, this shield is referred to as a battery element protector or a battery moss guard. The purpose of them is to catch the particles of lead and other impurities that precipitate from the electrolyte. This protects the element plates from moss buildup. These shields are usually made of polypropylene or a similar material that is unaffected by the sulfuric acid.
Element protectors greatly reduce the rate at which mossing occurs. This helps to protect our environment by extending battery life and reducing the number of prematurely discarded batteries. We manufacture element protectors in both standard and custom sizes.
