Pure-lead cells and thin-plate technology deliver reliable power, again and again, to meet the highest level of demand.

Full Throttle batteries fit the widest variety of vehicle needs and applications (Cars, trucks, motorcycles, marine, power sports, emergency responders and semi-trucks). From professional racing to serious vehicle enthusiasts, Full Throttle is the battery of choice. Tough, reliable, and built to last.

 Features and Benefits of Full Throttle Battery

  • Maintenance Free, Spill-proof, sealed construction provides an environmentally friendly non-hazardous battery that is DOT, IATA, ICAO and IMDG approved for transportation by land, sea and air.
  • Environmentally conscious, jar-formed, high-density plates undergo a 10-day curing process for superior bonding of the paste to the heavy duty lead, calcium and tin grids. This ensures fully formed, voltage matched plates for long life, true deep cycle functionality and recovery.
  • Compression of highly micro-porous, glass mat separator provides superior contact between electrolyte and plates for maximizing capacity while providing extreme shock and vibration resistance.
  • Our fire retardant ABS case, cover resins and epoxy seals combine to form a truly safe sealed battery that is non-hazardous, highly durable, and capable of being mounted in any direction except inverted.

Fullriver Battery will provide the warranty to the original purchaser subject to the terms and conditions stated herein for the Full Throttle product line in accordance with the periods specified by application in the corresponding table (left).


This warranty covers battery models as part of the Full Throttle series that become unusable or unserviceable due to defects in material and/or workmanship. The following detail is required to claim warranty and must coincide: (1) Proof of Purchase, (2) the Fullriver manufacturing date code, and (3) proof of proper auxiliary charging for batteries that (a) are idle for long periods, (b) used for duty other than (or in addition to) primary starting. The batteries must have been sized properly for the power demand, used in the application for which it was intended, and charged with an approved charging profile (ref. Fullriver AGM Charging parameters). Batteries used for cycling must be fully charged after any significant use or at least 1x/week for lighter duty service, or monthly during periods of non-service. The charge cycle must be allowed to complete a full 3 stage charge profile that includes a float or finish stage. Heavy (deep) cycling will not be covered under warranty. For heavier or dedicated deep cycling applications, Fullriver Battery recommends the Fullriver DC Series battery line. Batteries must be used on an approved load tester. The minimum performance threshold is 50% of rated capacity. This warranty applies to batteries sold after July 1st, 2020.
