Replacement Battery for Jump n Carry Units

This 12V 18AH AGM battery replaces the original unit in Jump n Carry JNC660 and JNC4000 jump starters. It uses advanced AGM technology for a sealed, maintenance-free design. The battery measures 7.13 in by 3.00 in by 6.6 in and weighs 12.5 lbs. It is a direct 100% OEM-compatible replacement for the PowerStar® brand original.

Verify Terminal Type and Dimensions Before Ordering

Confirm that your jump starter uses nut and bolt terminals matching this battery's configuration. Check the physical dimensions of 7.13 in length, 3.00 in width and 6.6 in height against your unit's battery compartment. Ensure the 12V 18AH rating matches the specification label on your existing battery. This unit replaces several OEM part numbers including Yuasa NP18-12B and Powersonic PS-12180.

Integrates Into Portable Power and Backup Systems

The sealed AGM construction allows installation in any orientation without leakage risk. It powers jump starters, emergency lighting, security panels and mobility scooters. The deep-cycle design supports repeated discharge cycles in UPS backup and fire alarm applications. Nut and bolt terminals provide a secure connection for high-current draws during engine starting. Buyers needing a higher amp-hour capacity or a different terminal style should look elsewhere.

Questions about this item

What comes in the box and do I need to buy terminals separately?

The battery ships with nut and bolt terminals included so no separate terminal purchase is required for installation.

Should I choose the 18 Ah version or one of the 15 Ah 17 Ah 19 Ah or 20 Ah alternatives listed?

Select the 18 Ah model to match the original Jump n Carry JNC660 or JNC4000 specification; the other capacities are cross-references for different equipment.

How long will the 18 Ah AGM battery actually run my jump starter before needing a recharge?

The 18 Ah rating means the unit can deliver 1 amp for roughly 18 hours or proportionally higher current for shorter periods depending on the load you apply.
