Marine Starting Batteries
We stock both conventional low maintenance and sealed maintenance free (SMF) marine batteries to meet your starting battery needs.
If you're not sure what would be best for your need - call us 02 9970 6999 and we'll give you friendly, free advice.
Conventional Low Maintenance Marine Batteries
These batteries are specifically designed to meet the high cranking starting requirements of modern marine engines.
The Low Maintenance Hybrid technology design offers vent plug accessibility for the ongoing maintenance of electrolyte levels to achieve extended battery life.
The problem of wave shock and engine vibration in Marine applications has been addressed through a patented “Plate Lock Hot Melt” design process which adds robustness to the internal construction of the battery resulting in extended performance and battery life.
Ideal for heavy duty starting applications requiring a hybrid design battery.
Sealed Maintenance Free Batteries
The Marine range of SMF starting batteries are premium Calcium/Calcium technology and feature unique positive plate tissue design positioning them at the forefront of battery performance and technology.
Liquid Gas Separators in the Marine SMF range minimise electrolyte loss meaning there is no need to add water during the life of the battery.
The In built Magic Eye hydrometer enables visual checking of battery state of charge.
Ideal for Marine starting applications which require higher cranking (CCA’s) within a sealed battery design, plus the added benefit of Dual Terminal configuration.
Marine Deep Cycle Batteries (Conventional, AGM and GEL)
Conventional low maintenance deep cycle marine batteries
Extreme heavy duty deep cycle design, for the most demanding marine cycling applications.
Vent plug accessible for electrolyte monitoring and replenishment and featuring generous Amp Hour capacity across both 6 volt and 12 volt configurations.
Our range are tried and tested under the most demanding situations and marine environments.
Absorbed Glass Mat (AGM) Deep Cycle Marine Batteries
Absorbed Glass Mat battery technology allows for a fully sealed battery design with active electrolyte held in an absorbed state between the plates and immobilised by a very fine fibreglass mat.
The outcome is a dual purpose deep cycle battery with enhanced discharge and recharge efficiency, high resistance against vibration and leak proof non gassing benefits for safety, installation flexibility and peace of mind.
Our premium AGM dual purpose deep cycle batteries offer you the benefits of AGM technology and design across a full range of sizes and capacities to meet all your marine deep cycle needs.
GEL Technology (Gelled Electrolyte) Deep Cycle Marine Batteries
Gelled Electrolyte Deep Cycle Batteries represent the ultimate in marine deep cycle technology. Designed specifically for demanding deep cycle applications, their integrity is maintained even under extreme conditions.
GEL technology allows for a fully sealed battery design with active electrolyte held in a "gelified" state with internal recombination of more than 99% of internally produced gases. The battery is safe to use in gas sensitive applications. You can leave these batteries in a fully discharged state without any loss of battery capacity if you can't recharge immediately.
Gel deep cycle batteries are ideal for repeated cycling use and offer excellent performance over long discharges.
A little more expensive than AGM, the GEL battery can withstand deeper discharge and is exceptionally comfortable with installations that require the battery to sit for extended periods off from vertical. They are the ideal Deep Cycle power solution for discerning marine users.
GEL and AGM batteries are ideal for sailors as they don't spill or vent poisonous gases.
Marine Lithium Batteries
For specialist applications like live-aboards and high performance racing yachts we often install lithium batteries. These are light and very fast charging as well as offering premium performance and reliability.
Marine Dual Purpose Batteries (Starting and Deep Cycling)
Sealed Maintenance Free (SMF) Dual Purpose Marine Batteries
The SMFDCM range of Deep Cycle Dual Purpose batteries are Sealed Maintenance Free Calcium/Calcium design (no need to add water) with inbuilt ceramic disc flame arrestors to protect against accidental battery explosion from an external spark. The liquid gas separator enhances the maintenance free characteristics of the battery.
The SMFDCM range of dual purpose (Starting and Deep cycle) marine batteries are ideal if you want extended hours of cycling and strong starting , through a larger capacity (AH) and higher cranking (CCA) battery.
Absorbed Glass Mat (AGM) Dual Purpose Marine Batteries
Absorbed Glass Mat battery technology allows for a fully sealed battery design with active electrolyte held in an absorbed state between the plates and immobilised by a very fine fibreglass mat. The is gives you a dual purpose battery with enhanced discharge and recharge efficiency, high resistance against vibration and leak proof non-gassing benefits for safety, installation flexibility and peace of mind.
Our AGM Marine batteries offer you an excellent dual purpose battery power solution for when you need engine starting capacity as well as cycling ability to power accessories.
