Which Dashcam Battery? (Updated: October 2025)

Which Dashcam Battery? (Updated: October 2025)

Which auxiliary dashcam battery is the best?

We offer three brands at Dashcam Specialists: Cellink, BlackVue, and Thinkware.

All of the dashcam brands we offer are compatible with these auxiliary dashcam batteries.

We offer three battery capacities: 4,500mA, 6,000mA, or 7,500mA (milli-ampere-hour). Every capacity serves to your requirements and budget needs.

Price-wise, the Cellink Neo 6 Slim is $299 incl. GST and offers a 6,000mA capacity with a local 2-year warranty. This is by far the best value for the money in the country.

Which capacity is ideal and or better?

It really depends on the environment your car is parked in and the frequency of your car usage.

Suppose you use your vehicle at least once every 2 or 3 days (with an average commuting time of 30~40 minutes), and provided that your car isn't parked in front of a windy tree or a beehive, a 6,000mA battery should be enough.

The key benefits of a dashcam battery are:

  • Powers the dashcam in Parking Mode without relying on the vehicle’s battery
  • Allows extended operation with up to 55 hours of continuous recording time (depending on the dashcam model, but the assumption here is Full-HD 1080p, with minimal motion detection)
  • Quick charge time of 50 minutes when hardwired or 100 minutes via cigarette lighter socket (!)

If your dashcam is a 4K resolution at the front or a 3-channel unit, and/or is a high-energy-consuming dashcam, then the highest-capacity battery is the right choice.

There is a catch, though.

The bigger the battery, the longer the time needed to charge it (like smartphones). It means that your daily commuting times would need to be sufficient to deliver the hours of parking mode recording. A Cellink Neo 8+ requires 50 minutes at the fast-charge setting to a full charge.

If your one-way commuting time is less than 20 minutes, an auxiliary dashcam battery might not be for you.

Why are some dashcams not compatible with dashcam batteries?

Most renowned branded dashcams are fit for parking mode. This means that when the dashcam detects a change in mode to parking mode, it ensures that the system consumes less energy than normal. (Continuous Driving Mode vs. Event Detection Parking Mode)

The BEST dashcam to pair with an auxiliary dashcam battery

At Dashcam Specialists, we believe these (see below) dashcams are the benchmark in terms of parking mode effectiveness. Why? Conventional dashcam brands and models (even good ones) do not yet offer a Low-Power Impact Parking Mode feature.

Modern high-tech dashcams go beyond and offer a low-power impact parking mode, which may limit recording to impact detection (and non-motion) while parking mode (but is the most crucial evidence that you'll ever need!), but prolongs the overall stand-by hours to detect an impact, where the system conducts a quick boot for footage capture upon wake-up.

To date, only a few dashcams can perform this (and properly). They are:

  • BlackVue ELITE 8 Series
  • Vugera SV2 PRO
  • Viofo A329S Series
  • Thinkware U3000/1000 with Radar

Thinkware dashcams go beyond this and offer a radar module where motion is not detected via the image sensor. Instead, the dashcam uses a radar sensing module, which consumes minimal energy which further prolonging the stand-by hours. Such high-end solutions are nice to have, but come at a cost.

Does installing an auxiliary dashcam battery void a new car warranty?

Any hardwiring to a vehicle with a new car warranty will become void if the manufacturer can prove that the external source that was hardwired to the vehicle was the root cause of the damage.

Therefore, should you be concerned about a new car warranty becoming void, DO NOT WORRY! All of our dashcam batteries can be fitted with an optional cigar-jack charging cable. This means that there will be no hardwiring to your vehicle whatsoever. Although this is a peace of mind solution, there is one downside. Fast charging isn't supported when a cigar-jack cable is used. It's still worth it, though. Better safe than sorry.

Our verdict and recommended pick for starters: The Cellink Neo 6 Slim

A 6,000mA battery package delivers the best value for money. It is compact, affordable, and delivers well-proven reliability backed up by a local 2-year warranty.

The Cellink Neo 6 Slim is the best value for money.

If you prefer a larger capacity (7,500mA, +25% more than the ) for longer standby and recording time with added features such as a smartphone app to view your charging status, then the Thinkware i-Volt MAX, Cellink Neo 8+ Slim, and the BlackVue B-130A are the best.

Unless you intend to frequently view your dedicated smartphone application, our pick remains the 6,000mA capacity Cellink Neo 6 Slim.
