In contrast to the quick surge of power that is required for starting, deep cycle service means that the battery bank is called upon to deliver smaller amounts of current over longer periods of hours or days, rather than seconds. They are used for auxiliary loads such as house power, trolling motors, auxiliary equipment, communications, electric vehicles, scrubbers/sweepers, golf cars, etc.

    Of course, Federal's deep cycle series can deliver plenty of starting power, but they are specifically designed and built to withstand the special rigors of long, deep discharges and long, slow recharges, an environment which can literally tear ordinary batteries apart from the inside.

    There are other, so-called, deep cycle batteries available at lower prices but it all gets down to the old maxim, "you get what you pay for". Federalšs deep cycle batteries are the premium option because they deliver so much more.



  • Glass mat, dual insulated,"deep pocket" envelope separators resist internal shorting, prevent plate shedding and extend battery life
  • Compu-cast, heavy duty grids provide maximum durability
  • Compu-cured plates are precision pasted with specially formulated deep-cycle oxide for maximum performance
  • Specially designed chambered vent pods reduce terminal corrosion
  • Convenient carrying handles allow for easy transport and installation

  • Complete line of 6 & 12 volt sizes including replacement sizes for Advance, Clarke, Tennant and many others
  • New super-insulating, micro-porous polyethylene envelope separators protect the plates, eliminate short circuits and dramatically extend battery life
  • Positive plates are glass wrapped, similar to motive power industrial batteries. The glass fibres imbed themselves into the surface of the plate to add reinforcement....like "re-bars" in concrete. This reduces plate shedding and extends life
  • The amount of active material on the positive plate has been increased for added performance and life
  • The manufacturing process controls have been improved for higher quality, performance and life
