APU Batteries Reduce Regens Through Idle Reduction

For most commercial truck drivers, regens range from a minor inconvenience to a significant issue. But did you know cutting down on idling dramatically reduces the regularity of regens, extends the life of your DPF and DOC, and reduces fuel spending? Installing an electric APU with efficient lithium batteries is one of the easiest ways to reduce your idle times!

How Does Idling Damage the Aftertreatment System?

The DPF and the DOC are big filters that trap unburnt fuel, soot and other harmful particles to prevent them from escaping from your exhaust pipe into the surrounding air. Through passive and active regens, the truck uses hot exhaust to burn the accumulated material off the face of the DPF, clearing the passage through it. The DPF is designed to self-clean in this way and is equipped to burn off the build-up from regular driving.

However, as the lowest duty cycle of a commercial truck, idling generates much more soot than driving. Engines built since the introduction of anti-idle legislation aren’t designed to handle this quantity of soot. The result is that the DPF gets overwhelmed and prematurely clogged up. Excessive idling burns through enormous amounts of fuel and increases the number of regens. This means shorter maintenance intervals, early DPF cleaning and a reduced working life for this expensive part. But by cutting your truck’s idle times, you can extend your DPF’s working life and reduce inconvenient forced regens!

How Can Batteries Reduce Idling?

Many modern trucks have an idle reduction system called an electric APU. This system allows you to reduce idle times by powering your sleeper cab electronics when the engine’s switched off. Trucks without an APU often have to idle for extended periods to power sleeper-cab features like temperature control, kitchen appliances and small electronics. This drives up your operating costs, burning lots of increasingly expensive fuel! On top of this, idling puts unnecessary pressure on your engine and aftertreatment system. By installing an electric APU, you can power your sleeper’s essential electronics, saving your DPF for driving, not for idling.

Why Choose Lithium APU Batteries?

Lithium batteries may seem more expensive in the short term and this initial cost puts some drivers off. But overall lithium batteries actually save you money! They last 10× longer before being replaced and have twice the runtime between charges, without reduced performance when the battery runs low. The result is that your appliances run for longer, but you don’t have to idle to charge your batteries.

Lithium batteries are also very resilient, surviving rough trucking conditions from knocks and jolts to extreme temperatures and splashback. You can find out more about the benefits of lithium trucking batteries here, or head to our LightningVolt™ page to purchase a Roadwarrior lithium battery.

Better Coating, Better Performance.

Roadwarrior is the only manufacturer to use Metalcor® catalyst technology across its entire range of Diesel Oxidation Catalysts (DOCs) and Selective Catalytic Reduction catalysts (SCRs). Metalcor® catalysts feature high activity catalyst coatings fused to thinner, stronger, catalyst substrates to guarantee maximum performance under the harshest conditions.

Metalcor® catalyst coatings are designed and produced in our own labs. We then inspect each unit to ensure you get more fuel efficiency, lower consumption of DEF, and long term performance from your heavy duty engine!

Roadwarrior Has You Covered!

All Roadwarrior emissions parts carry a full value 12 month warranty.

LightningVolt lithium batteries carry a full value 30 month warranty.

To make the process hassle-free, our parts have a metal nameplate with the serial number, so even after 500,000 miles of service, it’s still easy to identify. This avoids the common problem of serial numbers printed on stickers that burn off after the first start-up, making them impossible to return. Our failsafe system allows us to work in your interests, honouring claims for on-road and off-road replacements, and giving you peace of mind.

And since Roadwarrior parts are designed to meet or exceed OEM specifications, you can rest easy knowing our direct fit parts will take the problems out of your aftertreatment without interfering with your OEM warranty.

Next Day Is Nice, Same Day is Better!​

A faulty emissions control system can cost you thousands in wasted man-hours as your heavy equipment sits in the shop awaiting a new part. Whether it’s a truck behind on orders, a bus that can’t take passengers, or heavy machinery delaying construction deadlines, Roadwarrior can get you moving again! 

Roadwarrior has twelve warehouses across the U.S.A. and Canada, which can deliver the most popular aftertreatment parts in 1-2 days. With over 1,000 DPFs, DOCs and SCRs on offer, Roadwarrior offers the largest aftertreatment catalogue.

*LightningVolt lithium batteries ship directly from Roadwarrior’s production facility within 2-4 days.
