Our portable GIANTZ Deep Cycle Battery provides off-the-grid power supply for 4WD vehicles, caravans, campers, trailers, motorhomes, saltwater/marine applications, and all 12V appliances including portable fridges and washers. The 140Ah 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. And with its advanced AGM technology, the battery enables better electrolyte absorption, cyclic stability 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.


  • Please charge the battery on receiving it even if the battery will not be used in the near future.
  • Maintenance-free means the terminals need not be refilled. However, the battery must be recharged periodically after use.
  • It is advised to charge the battery every 3 months if not in use for long periods. This is to prevent over-discharging of the battery which will cause irreparable damage to it.
  • AGM deep cycle batteries have a much longer cycle life if they are exhausted to a small degree and then recharged, rather than draining all their power and recharging all the away.
