SKU CH-WGJY-8F27F

A 12V 18Ah AGM jump starter delivering 950 peak amps with maintenance-free, spill-proof operation

  • AGM technology prevents electrolyte leakage for safe operation in any position
  • 100% OEM replacement ensures direct fit and reliable starting power
  • Maintenance-free design requires no water checks or specific gravity testing
  • Gas recombination system recovers over 90% of generated gas during normal use
  • 12V 18Ah 950 specification delivers strong cranking performance for vehicle jump starts

Portable 12 V jump starter

This unit delivers 950 cranking amps from an 18 Ah sealed AGM battery to start cars, trucks and light commercial vehicles. It is built for owners who need a compact, maintenance-free power source that can be stored in any orientation without risk of acid leaks.

AGM design and sealed case

Absorptive Glass Mat construction holds the electrolyte in fine glass-fibre mats, eliminating spillage and allowing safe transport by air under IATA non-spillable rules. The recombination system handles over 90 % of gas generated during normal use, so the battery never requires water top-ups or specific-gravity checks.

Maintenance-free mounting freedom

Because the case is completely sealed, the starter can be mounted upright, on its side or upside down without leakage, fitting tight engine bays or tool compartments. The 12 V output terminals accept standard clamps, and the 100 % OEM replacement format means it drops into existing battery trays with no adapter brackets needed.

Questions about this item

Will the AGM battery ever need water or electrolyte checks during its 4-7 year life?

The sealed AGM design recombines over 90% of gas internally and has no provision for adding water, so no electrolyte maintenance is required.

What limits the 950 A jump-start output during repeated cranks?

The 18 Ah capacity and internal resistance of the AGM cells determine how many high-current bursts can be delivered before voltage sags.

Does the sealed case get hot or vent gas when left charging all day?

Gas recombination exceeds 90% and the non-spillable construction prevents electrolyte loss, so heat and venting stay minimal during extended float charging.
