Battery mossing refers to the build-up of particles on the top edge of battery element plates. Mossing occurs in all lead-acid batteries at a very slow rate over a term of many years. As a result, the mossing may in time cause a short circuit between the plates. In addition, battery mossing may cause a short between the plates and the plate strap. Mossing is made worse by overcharging, by rough handling, or due to normal motion and vibration when installed in mobile equipment.
To help solve this problem, battery makers install a thin 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 debris that form in the electrolyte. This protects the element plates from moss buildup. These shields are made of polypropylene or similar resin that is not affected 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 make element protectors in both standard and custom sizes. Our current drawings may be viewed by selecting one of the PDF icons below (your browser must be set to allow pop-ups).
