Batteries, alternators, dual battery and lithium systems, vehicle solar and caravan wiring. We are the auto electricians on Darling Terrace, and we have been sorting out the Upper Spencer Gulf's charging and 12V problems for a quarter of a century.
A family shop on Darling Terrace, not a call centre
Whyalla Battery Electric is, in our own words, a family owned and operated auto electrical business based in Whyalla, South Australia. Nathan and Theresa run it, and the name has been registered and trading here since February 2000.
Twenty six years in one town means most of the work walks in the door because somebody was told to come and see us. It also means we have seen the fault you are describing before, which is usually the difference between a diagnosis and a guess.
We are an in shop workshop, so the job comes to Darling Terrace rather than us coming to you. If you are travelling through and something has let go, ring first and we will tell you honestly whether we can get to it.

What is in the window
We are a REDARC and REDARC Solar stockist, and we carry Supercharge Batteries including the TruckMaster dual alloy range. If you have been told to get a specific unit fitted, there is a good chance it is already on the shelf.
02 / What we do
Auto electrical, batteries and 12V systems
Everything below is work we actually do in the shop at 7 Darling Terrace. If your job is not on the list, ring and ask, because the list is not the whole of it.
Batteries
Supply, testing and fitting for cars, utes, trucks, boats and machinery. We stock Supercharge Batteries, including the TruckMaster dual alloy range.
Alternators and starters
Charging fault diagnosis, then repair or replacement fitted in the workshop. If the charging system is the problem, we will find it before you replace anything you did not need to.
Dual battery systems
Designed and installed for touring, work utes and trade vehicles, so your fridge, lights and accessories run without ever flattening the crank battery.
Lithium and solar
Lithium battery setups and vehicle solar charging, wired with proper fusing and isolation. We are a listed 12V Power installer for dual battery and lithium work.
Caravan and camper 12V
Full rewires, repairs and fault finding on caravans, campers and camper trailers. Touring vans through Whyalla are a big part of what comes through the door.
Trailer wiring and plugs
Trailer plugs, Anderson plugs and connector brackets fitted properly to the tow bar, with the breakaway cable set up the way it should be.
REDARC brake controllers
Supplied and fitted flush into the dash so it looks factory, not bolted on. We are a REDARC stockist and carry the REDARC Solar range too.
Lighting and globes
Headlight globes, driving lights, work lights and trailer lights. Small jobs are welcome, and we will squeeze one in when we can.
Electric motors and generators
Service and repair work on electric motors and generators, listed under our long standing Electric Motor Repairs and Generator Repairs trade category.
A note on what we do not do, so nobody drives across town for nothing: we are a workshop, not a mobile or roadside service, and we are closed weekends.
Where a caravan job usually starts. Corroded terminals and heat damaged connections behind a panel nobody has opened in years.
03 / On the road
Caravans, campers and touring rigs
Whyalla sits on the run north and west, so a fair share of our week is somebody's van, camper or tug that has developed a fault a long way from home. Dead fridges, a solar setup that has stopped charging, a wiring harness that has taken a hit, lights that will not come on when the trailer is coupled.
We will fault find it, tell you what it will take, and where we can, we will get you moving again rather than parked up waiting.

05 / Licensing work
Guardian alcohol interlocks, fitted in Whyalla
We are an approved interlock installer and service provider for the Guardian alcohol interlock, and we are the Whyalla service centre listed on Guardian's own directory. That covers the whole of it: install, inspect, maintain and remove.
If you have been told you need one fitted to drive again, you do not have to go to Port Augusta or Adelaide for it. Ring us and we will talk you through what is involved.
As published on the Guardian Interlock South Australia service centre list.

“Yesterday I went in to enquire about getting some headlight globes changed and broken ones replaced. I didn't have anyone else to be able to help me as every other business in town was busy. I can't thank them enough for fitting me in that late in the afternoon, in such short notice too. What an amazing friendly professional customer service they provided at such a reasonable price as well. I highly recommend this business to everyone. Thank you for being awesome.”

“Good old fashioned amazing values and service … Sue and I can't thank you enough for going above and beyond to squeeze in repairing the wiring on our caravan as tourists even though you were very busy with priority regular business. Staying back until 8pm to get the job done … unreal in this day and age. All is working well with the solar now. Again, a heartfelt thank you Nathan and Theresa”
