Optronics International, a leading manufacturer of vehicle harnesses, electronic control systems and LED lighting, has introduced the revolutionary Co27 DC-DC Battery Charger, a patent-pending intelligent charging system that solves chronic trailer battery failure caused by inadequate charging through standard trailer wiring. The Co27 delivers a three-stage charging cycle to rapidly restore and maintain 100% battery capacity, reducing fleet downtime and maximizing battery lifespans.

Why it matters

Batteries on commercial trailers with electric-over-hydraulic power packs, powered landing legs, liftgates and similar equipment routinely fail well before their expected service life due to inadequate charging through standard trailer wiring. The Co27 eliminates this issue, keeping batteries fully charged and in peak condition to ensure consistent dump cycles, reduce the risk of batteries freezing, and extend the lifespan of expensive trailer components.

The details

The Co27 DC-DC Battery Charger activates when it detects 13.2 volts or higher from the towing vehicle's alternator and delivers a three-stage charging cycle: bulk charging to rapidly restore a deeply depleted battery, absorption charging that monitors recovery as the battery approaches capacity, and float charging that maintains 100% state of charge. It also has adaptive intelligence to reduce current draw when it detects high resistance from corroded connectors or aging wiring, protecting upstream wiring and fuses. The Co27 draws zero standby current when the towing vehicle is not running, keeping trailer batteries fully charged between jobs.

  • Optronics will showcase the Co27 at NTEA Work Truck Week 2026, March 10–13, at the Indiana Convention Center in Indianapolis.
  • The Co27 DC-DC Battery Charger is in limited stock and currently available for shipping.

What they’re saying

“The cost of not having this product is significantly higher than the cost of having it. One bad experience, a failed dump cycle, a stalled liftgate or a battery replacement that pulls an operator off the road, can easily exceed $1,000 when you factor in the battery, the service call and lost productivity. The Co27 is equivalent to the cost of just one battery.”

What’s next

The judge in the case will decide on Tuesday whether or not to allow Walker Reed Quinn out on bail.

The takeaway

The Co27 DC-DC Battery Charger is a game-changing solution that addresses a longstanding industry problem, helping fleet managers and trailer builders reduce maintenance costs, downtime, and the risk of expensive trailer component failures caused by chronically undercharged batteries.
