Giantz AGM Deep Cycle Battery 12V 120Ah Marine Sealed Power Portable
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 120Ah 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.

Very pleased Would not hesitate if l have to purchase another one in the future thanks again
Just what i needed a top class battery at a great price
This 120AH AGM battery seems well constructed & it was certainly good value. I haven't used the battery for it's intended purpose yet (caravan house battery), but if it performs to the specs advised it will provide good service.
the battery is great time will tell how good it is if i get 6 years out of it .it will be good
the deep cycle battery weight is 25 kg quite heavy it was supposed to come with 2 securing straps, however,, one was missing and the other was badly frayed, the high probability was dropped during transit complements of Australia Post.
I have used this brand before and find it very reliable, so why change now.
great battery, huge cranking power,very good price.
