Why Pros Recommend a Smart Battery Maintainer for Seasonal Storage

We love our classic cars, motorcycles, and RVs. But seasonal vehicles sit idle for months at a time. That creates problems, like quiet battery drain driven by two main factors: natural self-discharge and parasitic loads. Both can lead to premature battery degradation. That is why pros recommend seasonal battery maintenance.

For decades, seasonal vehicle owners have relied on basic trickle chargers to address off-season battery drain. But things are changing. The professionals are gradually understanding that there is a better way. More and more, they are recommending setting aside the old trickle charger in favor of a smart battery maintainer.

Understanding the science behind battery storage explains why smart battery maintainers are better than trickle chargers. So let’s get into it.

The Problem With Trickle Chargers

All types of batteries naturally self-discharge over time. When a seasonal battery is left in its vehicle, self-discharge is enhanced by parasitic draw from devices like clocks and electronic modules. In theory, a trickle charger prevents both. But it does so at a cost.

Trickle chargers deliver a continuous, static voltage and amperage directly to the battery through its terminals. The charge certainly prevents the battery from draining. And yet, there is a trade-off. Trickle charging creates a serious long-term issue: chronic overcharging.

A battery at 100% capacity cannot handle additional current. So instead, excess energy is converted into heat. Here is the result of that conversion:

• Electrolyte Evaporation – Excess heat transforms the water inside a standard flooded battery’s lead-acid solution into hydrogen and oxygen gas. The liquid electrolyte boils away, leaving internal lead plates exposed to air and subject to permanent oxidation.

• Thermal Runaway – While electrolyte evaporation isn’t a problem for AGM or Gel batteries, thermal runaway is. Excess heat increases internal pressure, venting valves open to release that pressure, and the battery is permanently dried out. If the valves do not open properly, the battery could actually explode.

Trickle chargers used to work well enough in years past because battery technology was different. But as the technology has improved, trickle chargers are no longer appropriate. A better option is a smart battery maintainer from a brand like Clore Automotive.

How Smart Battery Maintenance Saves the Day

Clore’s smart battery maintainer brand is PRO-LOGIX. Unlike trickle chargers, a PRO-LOGIX smart battery maintainer is designed to utilize microprocessor-driven multistage charging logic to dynamically monitor battery health in real time. The maintainer automatically adjusts voltage and amperage throughout the charging process to maintain both capacity and overall health.

Without getting into all the details, your typical smart battery maintainer offers three distinct phases that cannot be replicated by trickle chargers:

• Bulk Charge Phase – The bulk charge phase safely brings a battery up to 100% capacity using precise voltage thresholds determined by each battery type. A smart unit can safely charge flooded, AGM, Gel, and lithium batteries.

• Float Mode – At full charge, a smart unit automatically reduces its voltage to a safe maintenance level that only offsets self-discharge. No excess heat or gas is generated.

• Rest and Exercise – Advanced maintainers, like those built by PRO-LOGIX, also include automatic rest and exercise cycles. A fully charged battery is allowed to rest and safely discharge to a certain threshold. The unit also exercises the battery by applying a load across both of its terminals. Then the battery is safely charged again.

Smart battery maintainer technology is truly remarkable. It not only maintains battery health during off-season storage, it actually maximizes battery life and optimizes performance. So if you have a seasonal vehicle, it’s time to replace your trickle charger with a smart battery maintainer.
