Koba Deep Cycle Battery (90Ah or 100Ah)

Koba Deep Cycle Battery (90Ah, 100Ah or 115Ah)

The Koba Deep Cycle Battery is a sealed AGM (Absorbent Glass Mat) battery available in 90Ah, 100Ah and 115Ah capacities, giving you flexibility to match your caravan, motorhome or RV's house power needs. Manufactured by Koba in a dedicated calcium battery facility in South Korea and distributed in New Zealand by R&J Batteries, it's built for repeated charge and discharge cycles rather than the short, high-current bursts of a car starter battery.

• Enveloped separators and ultramicro fibre glass mat for low resistance and durability

How do I know this will fit / suit my setup?
Check the dimensions, weight and terminal type listed in the Specifications tab against your existing battery box and wiring, and confirm which capacity (90Ah, 100Ah or 115Ah) suits your power needs. If you're unsure which option to choose, contact us and our team can help.

What's the warranty?
Warranty terms vary depending on the capacity you choose. Contact us and we can confirm the exact manufacturer warranty period for your selected model.

Which capacity should I choose – 90Ah, 100Ah or 115Ah?
The right capacity depends on your daily power consumption and available space. Higher capacity means longer runtime between charges, but also a larger, heavier battery. Contact us if you'd like help sizing the right option for your caravan or motorhome.

Do I need a special charger for an AGM battery?
AGM batteries can be charged with most modern smart chargers. Select the AGM setting if your charger has selectable battery type modes, and avoid chargers with an equalise stage, as this can damage sealed AGM batteries.

How do I know what capacity I need?
Calculate your daily power consumption in watt-hours (Wh) by adding up the wattage of each appliance multiplied by hours of use, then divide by 12V to get Ah. For AGM batteries, size to roughly twice your daily consumption to allow for a safe 50% depth of discharge. Contact us for help sizing your system.
