TJM Dual Battery Systems: A Deep Dive

Your car can run on two different batteries with a TJM Dual Battery System, which is a necessary feature for people who need extra power for accessories, camping appliances, or business operations. Because of the system’s dependable power supply, the primary battery in your car will continue to be used for engine starting, with the auxiliary battery taking care of any additional power requirements.

There’s nothing like trying to head off in the morning and finding you can’t start the car!

Rather than risk running down your vehicle (crank) battery with 12v lighting or a fridge, have an auxiliary battery installed under the bonnet or in the back of the vehicle in a battery box. Be aware that some batteries may need to be vented externally (for example a standard lead acid battery will sit under the bonnet, but for inside the vehicle a sealed battery will be required).

Start by writing a list of what you need to run when your power cord is just not long enough. Once you establish your power needs you can start looking at the battery you will use to provide it. Keep in mind that batteries do not like being fully discharged! They much prefer being drawn down to about 50% of their capacity, and then being topped back up soon after. You will get a much longer battery life if you can make this happen. You can TJM, you will get the best tjm dual battery system for your vehicle.

It’s important to get the right battery to suit your requirements – the battery size and type will be determined by exactly what you want to run on them. For example, to run a fridge and lighting, a deep cycle battery will be required. If you plan on running your second battery in a trailer (or caravan) an Anderson Plug setup will enhance the charging capabilities of your vehicle.

Modern vehicles have different charging systems, so what worked in the past may not work now. It’s always a good idea to get advice from our experienced staff before spending money on a system that won’t meet your needs.
