Dash Cam Battery Packs

That depends on how many cameras you run and at what resolution. A front-and-rear setup draws roughly twice what a single camera does, so it gets roughly half the hours. Our battery calculator asks four questions and gives you a real answer for your setup, including when you don't need a battery at all.

Not to the point of stranding you, in most cases. Every hardwire kit has a low-voltage cutoff that shuts the camera down while there's still enough charge to start the engine. An old or weak battery can still let you down, especially in winter. The subtler issue is wear rather than a dead battery: your starting battery gets cycled a little every night, which it was never designed for.

No. It charges from the vehicle while you're driving and runs the camera independently while you're parked. Your starting battery is never involved in parking mode.

Because we rate every battery on the same basis, and they don't. Each brand picks its own power draw for its headline number, which makes their figures impossible to compare. We use 1.7W for a single camera and 3.2W for front-and-rear across everything we sell. Sometimes that makes a number higher than the box claims, sometimes lower — our own LDS P7D is listed at 45 hours where Energywell (the manufacturer) says 49, because 45 is what it does on our basis.

Yes, in both directions. A cold starter battery holds less usable charge and hits the cutoff sooner, so vehicle-powered parking mode gives noticeably fewer hours in January. Lithium packs aren't immune either — they charge only above freezing and give shorter runtime in deep cold. They keep their advantage, but they're not magic, and mounting location makes a real difference.

It refills while you drive. Depending on capacity and how it's wired, most packs need somewhere between 35 minutes and two and a half hours of driving for a full charge. This matters more than most buyers realise: if your commute is short, a bigger pack may never reach full, and a pack that never fills is worse than a smaller one that does.

Under a seat, in a trunk cubby, or behind a trim panel — somewhere out of sight, secured so it can't move. Size is the deciding factor and it's why we favour the compact LDS packs; they fit vehicles the larger ones don't. When we install, we pick the location around your vehicle's layout and its temperature behaviour.

Plenty of customers do. You'll be connecting the pack between your hardwire kit and the camera, then routing and securing it. Budget a couple of hours and be comfortable with basic 12V work. Every pack ships with instructions and our support team can help by phone.

Yes. The hardwire kit is what draws power from your vehicle to charge the battery while you drive. Some cameras include one. If yours doesn't, see our hardwire kits, or we'll supply it when we install.

Almost certainly. These packs output standard 12V to the camera, so brand doesn't matter. The exceptions are brand-matched features rather than compatibility — the Viofo, Thinkware and BlackVue packs pair with their own apps.

One year on the battery itself. If we install it, our workmanship is covered by our lifetime installation warranty.
