No more batteries left empty during the winter! H-Tronic offers an excellent automatic permanent charger for wintering lead batteries!

The plug charger can be used for single charging or for continuous charging over the winter time. Thanks to an integrated protective function in conjunction with an LED indicator light, it is reverse-polarity proof.

In addition to the charge indicator, this informs about the current state. Particularly harmful for batteries is the deep discharge, which unfortunately often occurs in the cold season when the scooters are not used. It is therefore advisable to remove the battery if it is not driving for a long time. Deep discharge in most cases destroys the battery. This occurs not only due to extreme cold and frost, but also due to the natural self-discharge of the battery when not in use.

The H-Tronic AL300 intelligently reduces the charging currentas soon as the battery's charging stop voltage is reached. This prevents overcharging. The device then works in maintenance mode and maintains the battery until the start of the season! You don't have to constantly measure the battery voltage!

This charger ensures battery-saving charging, keeps motorcycles, cars, vintage cars, boats, motorhomes, tractors and devices that are not used for a long time, e.g. over winter, always ready for use and thus protects the battery from harmful deep discharge. It is not possible to overcharge the battery with this device. Also for maintenance-free lead/lead-gel batteries!

Check the level of acid batteries, refill only with distilled water according to manufacturer's specifications! According to manufacturer's specifications, leave the chamber closures open due to gassing while charging is in progress.
