When people think of fleet battery failures, they picture freezing winter mornings and snow-covered depot lots. It is true that cold weather severely reduces cranking power, but the reality is much more insidious: summer heat is the actual battery killer.

For municipal fleet managers overseeing everything from transit buses and emergency response vehicles to off-season snowplows, the extreme temperatures of June and July are quietly destroying the chemical batteries across your entire fleet. The heat does the damage; the cold just finally finishes the job.

Here is why heavy-duty batteries fail in the summer heat, and why traditional rescue tools are no longer the best solution for the modern city garage.

The Science of Heat Degradation

Lead-acid batteries rely on a delicate chemical balance to store and deliver energy. When temperatures in a city depot or an asphalt lot soar past 90 degrees, that chemical process goes into overdrive.

High heat accelerates the internal corrosion of the lead plates. More importantly, it causes the essential water inside the battery electrolyte to evaporate. Once those plates are exposed, they begin to warp and sulfate rapidly. A battery that tested perfectly in April can become completely compromised after just a few weeks of baking in the July sun, leading to a sudden, unexpected failure right when a transit bus or utility truck needs to roll out.

The Flaw with Traditional Rescue Tools

When you inevitably encounter a dead battery starter situation on the lot, the immediate reaction is to grab the heavy-duty jump box.

However, there is a glaring problem: traditional jump start devices are powered by the exact same lead-acid chemical batteries that are currently failing inside your vehicles. If your jump cart has been sitting in the hot corner of the maintenance bay for three weeks, its internal battery is also degrading and losing its charge. Dragging a heavy, 150-pound chemical jump box across a hot lot only to find out it doesn’t have the juice to crank a heavy diesel engine is a massive waste of technician time.

The Supercapacitor Advantage: Enter the KrankingKart

To eliminate the anxiety of dead batteries and failing jump boxes, municipal fleets are upgrading their maintenance bays to electrostatic technology.

Unlike chemical batteries, supercapacitors store energy in an electric field. This means they are completely immune to the extreme temperatures that evaporate battery fluid and warp lead plates. The KrankingKart by Koldban is the ultimate expression of this technology for heavy-duty fleet yards.

• Heat-Proof Reliability: The KrankingKart will not degrade in a sweltering summer maintenance bay. It is entirely maintenance-free and never needs to be left plugged into a wall to trickle charge.
• Massive Power: It can pull residual voltage from a seemingly dead vehicle battery, amplify it, and deliver the massive jolt of cranking amps required to start large municipal diesel engines.
• Lightweight Mobility: Because it doesn’t rely on heavy lead plates, the KrankingKart is incredibly lightweight and easy for a single technician to maneuver around a crowded lot.

Keep Your Essential Vehicles Moving

Municipalities cannot afford downtime. Whether it is a blazing hot Tuesday in July or a sub-zero morning in January, your fleet needs to start on command.

Stop relying on the same chemical technology that causes the failures in the first place. Equip your maintenance team with a rescue tool that is always ready.
