This diagram shows how the Exide-Iron- clad Marine Battery is *floated”’ on the main bus. Write for Bulletin 3420-M, which gives a detailed de- scription of how it works. HE hook-up of the Exide Marine Floating System is simple. Exide- Ironclad Battery cells are floated in series across the main bus, with suit- able generator adjustment. The bat- tery thus absorbs peak loads in ex- cess of generator capacity. The result is smoother, more efficient and reli- able operation of generator sets. The Exide Floating System also permits the use of a smaller generator unit, and often takes the place of a third COMPACTNESS, CONVENIENCE, and ECONOMY are assured when an Exide-Ironclad Marine Battery is in- stalled aboard your boat. aE ELECTRIC STORAGE BATTERY COMPANY, talua(aalaaata fal CIRCUIT BREAKER — OVERLOAD £ REV.

These batteries are different from all others; they are ideal for the heavy, rough require- ments aboard ships. The positive plates of Exide-Ironclads are com- posed of slotted rubber tubes. These tubes permit free access of the elec- trolyte, yet retain the active material of the plate—just as a net retains the fish while allowing the sea to run through it. Exide-Ironclad Marine Batteries assure absolute dependability and a long life of economical service.
