12V Intelligent Smart automatic battery charger - 4A

Automatic 3 Stage Charger 12v-4A. This intelligent charger is suitable for all modern AGM/gel batteries and lead acid batteries between 17Ah and 48Ah automatically guarding against improper connection and accidental short circuiting. This is a 3-Stage charger that allows you to leave your battery connected until the next time you need it. Unlike 2-Stage chargers, which must be disconnected after charging to guard against "cooking" your battery, this charger will switch itself off once the optimum charge is reached. If the charge then drops over a period of time this charger switches itself back on and tops up the charge. The whole process is indicated by LED lights. Full instructions included.
