Common Questions About the Battery Disconnect Switch

Clear answers so you can buy confidently and install quickly

Will disconnecting erase ECU memory or radio presets?

Yes, a full cutoff removes power to ECU and radios. Back up settings or use a memory saver for long-term storage to avoid reprogramming.

Can I install this on the negative terminal?

Yes. Installing on the negative side removes parasitic ground loops and is the recommended method for many vehicles.

Do I need special tools to install?

No special tools. A standard 10 mm wrench loosens the battery clamp. The included handle helps remove the knob if needed.

Is this safe in rain, snow, or offroad use?

Yes. The sealed housing and nitrile O-ring protect against moisture, dirt, and corrosion for reliable outdoor performance.

What battery sizes and systems does it support?

Rated for most 12 V and 24 V systems with continuous and peak current capacities suitable for cars, trucks, RVs, marine batteries, and off-grid setups.

I was skeptical at first but this actually isolates power cleanly. No more surprises when I return after weeks of not using my car.

Bought for my offgrid shed battery and it performs great. Copper contacts feel high quality, and the gasket stops microcurrents that used to kill my charge over winter.

Perfect for prepping a stored vehicle. The full cutoff reset my radio settings so I backed them up first, but overall it prevented slow drains and handled cold temps without cracking.
