How A Callout Runs

Four Steps, One Visit

Most jobs are finished the first time we arrive, because the van already has your battery on it.

01

You Call

A real person answers, 24 hours a day. Tell us the suburb and the make of the set, and you get an honest arrival window before you commit to anything.

02

We Come To You

Plant room, rooftop, basement, switch room or compound. Tell us the access and any site induction on the phone and we bring what we need.

03

We Test First

Resting voltage, then the bank under a load test, then the charger output. Free, and before anything is sold to you.

04

Fitted And Gone

The right batteries fitted on the spot, terminals cleaned, the set proven to crank, old batteries taken away for recycling. Nationwide warranty on every unit.

Emergency

24 Hour Emergency Generator Battery Replacement

Mains dropped, the set cranked once and died — we are already awake. The 24 hour callout runs every day of the year, including public holidays, right across the Sydney metropolitan area.

Our vans carry N120, N150, N200 and Deltec DEL-N120 on board, so most emergency jobs are tested, fitted and the set proven to crank on the same visit rather than booked for another day.

On Site

On-Site Fitting Wherever The Set Stands

We come to where the set already is, because a genset is not going anywhere. Plant rooms, rooftop decks, basements, switch rooms, gated compounds, construction yards and remote farm sites are all standard work for us.

Sites with more than one set get 24/7 commercial support: scheduled load testing so a bank is replaced on a planned visit rather than during an outage, bulk replacement across several sets or sites in one attendance, priority callout and account terms.

The Right Battery

The Right Battery For The Set

A genset does not take a special "generator battery". It takes a heavy-duty engine-cranking battery, the same family a truck uses: N70ZZ, N120, N150, N200, the 31-series and Deltec DEL-N120. Which one depends on the engine, the cold cranking amps the manufacturer specifies, the tray size and the terminal layout — not on what happens to be in the van.

Larger sets run two batteries in a 24V series bank, replaced as a matched pair and never one at a time. The control panel, switchgear and any UPS are separate and take small VRLA-AGM or gel types. We carry Super Start, Supercharge, Deltec, ACDelco, Energizer, Amaron, PowerSonic and Trojan, all genuine date-stamped stock with a nationwide manufacturer warranty.

Questions

Service Area FAQs

The ones site and facilities managers ask most about coverage, access and how fast we can be there.

Almost certainly yes. The list covers the suburbs we get asked for most often, not the limit of how far we travel. If the set is anywhere in the Sydney metropolitan area, ring 1300 232 173 and we will tell you straight away whether we can reach you and how long it will take.
