Smart, automatic charging for 12V batteries

Keep essential 12V batteries healthy with the Unocho Battery Charger. This compact unit delivers a gentle 750 mA trickle and a fully automatic charging sequence that adapts as the battery reaches capacity. When full, it automatically shifts to maintenance mode, helping you manage seasonal storage or downtime with less worry.

Smart 3-Stage Charging

The charger follows a thoughtful three-step approach to protect and optimize charging across cycles:

• Constant current to start charging quickly when the battery is low
• Constant voltage high stage to safely raise the voltage as the battery accepts current
• Final float/maintenance stage to keep the battery ready without overcharging

Built-in Safety for Peace of Mind

Designed for automatic charging and ongoing maintenance, it includes essential protections such as reverse polarity, short circuit, over-voltage/current, overcharge/discharge, overload, and overheating. The SAE quick disconnect adds convenience while preserving safety.

Clear Status with LED Indicators
