The portable GIANTZ Deep Cycle Battery provides off-the-grid power supply for 4WD vehicles, caravans, campers, trailers, motor homes, saltwater/marine applications, and all 12V appliances including portable fridges and washers. The slim design makes this deep cycle battery compact and space-saving. Plus, the exceptional 135Ah 12V battery features an incredible cycle life of up to 1400 cycles, making it one of the most enduring in its class. What you get is a longer, consistent and more drawn out charge all the time. With its advanced AGM technology, the battery enables better electrolyte absorption, cyclic stability, better low temperature reliability and frequent charging without affecting performance. The bolt down terminals also allows for more reliable experience, and not least, the high oxygen-recombination efficiency results in superior deep discharge recovery. The maintenance-free deep cycle battery is completely sealed, spill-proof and does not leak gas for added safety and durable use.
