Practical charging advice.

Yes, for standard Australian 56 Series 10 A and 20 A round-pin connectors. A 10 A four-pin plug fits four-pin or five-pin 20 A sockets. A 10 A five-pin plug fits a five-pin 20 A socket. A 20 A plug does not fit a 10 A socket. See the complete fit table.

Yes, within the standard Australian 56 Series 10 A/20 A combinations shown in the table. Four pins provide three phases and earth. The fifth socket contact is neutral and is unused by the four-pin plug. A five-pin plug does not fit a four-pin socket. Compare all four combinations.

Yes. Stanbury configures AC plugs to customer requirements. The plug current rating can be higher than the charger’s required AC input current, but never lower. Compare AC input amps with plug amps, not the charger’s DC output amps. A larger plug does not increase the capacity of the supply circuit. Match the charger to site power.

Choose an appropriately smaller charger if the available charging window allows a longer charge. A multi-shift fleet needing a fast turnaround may need a supply infrastructure upgrade to support a larger charger. Compare the supply and charging-window options.

No. The series and size alone are not enough: standard SB housings must also match the keyed colour. For example, SB350 red mates with red and blue with blue; red does not mate with blue. Manufacturer-documented exceptions are listed separately. Check the colour-key rule.

Colour may indicate a site’s voltage convention, but it does not prove the actual battery voltage. Housing colours provide mechanical keying; companies may use their own voltage conventions. Read the battery voltage from its nameplate. Understand colour and voltage.

Yes. Compatible Stanbury multi-voltage chargers support different approved battery voltages with the correct setup and charging profiles, and provide wrong-voltage protection. That protection is limited to voltage; it does not cover wrong chemistry, charging profile or polarity. Read the multi-voltage guidance.
