From a powerful battery to a formidable power station. That is what our GIANTZ Deep Cycle Battery and Battery Box combo can do. On its own, the 135Ah 12V battery features an incredible cycle life of up to 1400 cycles. 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 allow for a more reliable experience, and not least, the high oxygen-recombination efficiency results in superior deep discharge recovery. And not to be outdone, the battery box easily fits the battery and together, they can power up a host of 12V devices including camping lights and portable fridges with its cigarette lighter socket as well as mobile phones and tablets with the two USB ports. The box itself can be charged using solar panels or any power source with its quick-connect Anderson plugs. Better still, the box comes pre-wired, so all you need to do is connect to the deep cycle battery terminals and it is good to go. More power to you. That is definitely true with the GIANTZ deep cycle battery and battery box.



1.Please charge the battery on receiving it even if the battery will not be used in the near future.

    a.Maintenance-free means the terminals need not be refilled. However, the battery must be recharged periodically after use.

    b.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.

    c.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.

    d.The deep cycle battery’s handle may come in black or white randomly.
