When reliable cranking power matters
Lead acid jump starters remain a proven choice where strong cranking performance, dependable stored energy and longer starting attempts are important.
They are used across cars, 4WDs, service vehicles, workshops, trucks, agricultural equipment and machinery, with models ranging from compact portable units through to heavy-duty commercial jump starters.
Because lead acid batteries store substantial energy, they can also suit applications where repeated or extended cranking may be required, particularly when weight and portability are less critical.
Lost production
Equipment isn’t earning while it’s sitting idle.
Service call-outs
Getting assistance to remote machinery costs time and money.
Operator downtime
Operators and crews can be left waiting.
Lead acid battery technology explained
Lead acid batteries have been used for vehicle starting for generations because they can deliver strong cranking current while also storing a useful amount of energy.
A lead acid battery uses lead-based plates and an electrolyte to store electrical energy. When a jump starter is connected to a vehicle, the battery can deliver the high current required by the starter motor while also supporting longer or repeated cranking attempts when the application demands it. Today, portable and commercial lead acid jump starters commonly use sealed battery designs that reduce maintenance and allow the battery to be built into a self-contained portable starting unit.
Types of lead acid batteries used in jump starters
AGM (absorbent glass mat)
In an AGM battery, absorbent glass mat separators hold the electrolyte in place. This sealed design delivers strong discharge performance, resists vibration and requires little routine maintenance, making it well suited to many portable and commercial jump starters.
Other lead acid designs
Lead acid batteries are also available in flooded, gel and other sealed configurations. Their construction, cranking capability, cycle life, charging requirements and suitability vary, so the design needs to be matched to the intended starting application.
Why lead acid works so well for jump starting
Strong cranking, plenty of stored energy
Lead acid batteries can deliver the high current a starter motor needs while also providing substantial stored energy.
Longer or repeated attempts
Lead acid can support longer or repeated cranking attempts, which helps with larger engines, workshop applications, machinery and vehicles that need more than a short starting burst.
Power for 12V accessories
Depending on the model, stored energy can also run compatible 12V equipment such as work lights, compressors and diagnostic equipment.
Proven and practical
Lead acid units are generally heavier than comparable lithium jump starters, but their proven technology, cranking capability and stored energy keep them a practical choice for workshops, service vehicles, trucks, agriculture and machinery.
Choose the right lead acid jump starter
Our lead acid range covers portable units through to heavy-duty 12V and 24V commercial jump starters, grouped by system voltage. Choose the voltage used by your vehicle or equipment, then select the unit that suits the engine size and application.
Cars, 4WDs, service vehicles & workshops
Compact lead acid jump starters for everyday vehicles, workshops, service vehicles and lighter commercial applications, with dependable cranking power and useful stored energy.
12V & 24V heavy-duty and commercial
Higher-output lead acid jump starters for trucks, buses, tractors, agricultural equipment, earthmoving machinery, workshops and demanding commercial use.
Looking after a lead acid jump starter
Lead acid jump starters are robust and dependable, but their performance depends on battery condition and state of charge. Letting the battery stay discharged for long periods can reduce capacity and shorten its life. Lead acid units generally need more regular charging and care than lithium or supercapacitor alternatives, so correct charging, suitable storage and periodic inspection are important.
Match the unit to the application
Choose a jump starter based on system voltage, engine size and the cranking power required. Heavy trucks, tractors and machinery may need significantly more starting capacity than cars, 4WDs and lighter commercial vehicles.
Use the correct charger
Use the charger or maintenance charger specified for the unit’s battery type and voltage. Approved maintenance chargers can generally stay connected when the jump starter is not in use.
Recharge after use
Recharge after starting a vehicle or machine so it is ready for the next use, and recharge periodically during storage. Don’t leave the unit discharged for extended periods.
Inspect regularly
Check the battery condition, cables, clamps and case for signs of damage, corrosion or deterioration, particularly on units carried in service vehicles or workshops.
Store appropriately
Keep the jump starter in a dry, secure location away from excessive heat, moisture and physical damage.
How a lead acid jump starter works
A lead acid jump starter stores electrical energy in an internal lead acid battery. The complete system includes the battery, heavy-duty cables, clamps, protection devices and charging system, all working together to deliver starting power when required.
01
Connect
Connect the jump starter to the vehicle battery using the correct polarity and make sure the clamps have a clean, secure connection. Position the leads safely and follow the unit’s operating instructions.
02
Deliver starting power
The internal lead acid battery supplies high current through the cables and clamps to support the vehicle battery and crank the starter motor.
03
Recharge and be ready
After use, recharge the jump starter so it is ready for the next vehicle, machine or emergency start.
