【12V Battery Charger 40-250｜7-Step Charger for Use While Mounted in the Vehicle】

This charger is designed for those who want to charge their battery without removing it, or for those who have fewer opportunities to drive and want to regularly maintain the battery’s condition.

With the 7-step charging method, it automatically progresses through the charging process while monitoring the battery’s status. It is easy to use even for those who are not familiar with charging and is a model well suited for everyday battery maintenance.

Convenience of Charging While Still in the Vehicle

Because there is no need to remove the battery from the vehicle, it reduces the hassle of carrying a heavy battery every time you charge it. It is also easy to use for maintaining vehicles you do not drive often, as well as cars that have not been operated for a long period.

There are two connection options: a clip type that is quick and easy to use, and an eyelet type that is easier to leave attached to the vehicle. You can choose according to the car you use and your storage environment.

Supports a Wide Range of 12V Lead-Acid Batteries

Compatible with many types of 12V lead-acid batteries, including WET, EFB, Ca/Ca, MF, AGM, and GEL. It can be used not only for passenger cars, but also for battery maintenance of motorcycles, small trucks, farm equipment, and more.

Supported battery capacity is 14–150Ah. After confirming the battery type and capacity installed in your vehicle, it is important to select a charger that matches your intended use.

Peace of Mind with Monitoring During Use

You can check the charging status and operating conditions via the LED indicator. A safety design that helps suppress short circuits and sparks is also included, making it easy to handle for daily maintenance.

It is also compatible with the IP65 protection rating, so it is designed to be usable even in environments where dust or water droplets may be a concern. However, please check the handling instructions before use and do not allow the charger body to get wet.

At LOGON, when replacing a battery, we help you sort out whether you should prepare a charger or prioritize replacing the battery, while also checking how the vehicle is used and the storage conditions. Depending on the battery’s condition, charging alone may not be enough to improve it.

If you find things like “the engine has been harder to start lately,” “I only drive on weekends,” or “I want to use a newly replaced battery in the best possible condition,” please consult us based on the maintenance approach that fits your vehicle.
