Giantz AGM Deep Cycle Battery 12V 140Ah Box Portable Solar Caravan

The Giantz AGM Deep Cycle Battery is a 12V, 140Ah sealed AGM battery rated for up to 1,400 cycles at 30% DOD, weighing 29.5kg with dimensions of 33 × 17.1 × 21.6cm. Designed for off-grid, marine, caravan, and 4WD applications requiring reliable sustained discharge without maintenance.

• AGM (Absorbent Glass Mat) technology — electrolyte is fully absorbed into glass mat separators; eliminates free liquid, making the battery spill-proof and safe for enclosed spaces like camper vans and boat cabins
• 1,400-cycle maximum life at 30% DOD — significantly longer service life than standard flooded lead-acid batteries; reduces replacement frequency in long-term off-grid setups
• Sealed, non-gassing construction — no hydrogen venting required; safe for use in sealed compartments, under seats, or in enclosed storage bays
• Superior deep discharge recovery — high oxygen-recombination efficiency allows recovery from deeper discharge events that would permanently damage standard batteries
• Bolt-down terminals — mechanically secured connections resist vibration loosening in mobile applications (4WD, marine, trailer); more reliable than push-fit terminals under load
• Wide operating temperature range — discharges from -15°C to 50°C; charges from -20°C to 50°C; maintains 65% capacity at -15°C for cold-weather reliability
• 1,200A maximum discharge current (5s) — sufficient for high-draw loads including inverters, winches, and compressor fridges
• Maintenance-free — no electrolyte top-up required; periodic recharge every 3 months during storage prevents over-discharge damage
• Carry handle included — facilitates repositioning in field or during installation without additional equipment
