Automatic Battery Charger: Smart Charging for Every Vehicle 2026

The automatic battery charger provides intelligent charging without needing to know the battery type—WET, GEL, AGM, PbCa—or figure out which charging current to use: just set the battery voltage value (6, 12, 24 V). Plus, features like maintenance charging, desulfation, boost, and start assist make it a versatile tool for any DIY enthusiast or professional.

Pulse 50 is an automatic battery charger and maintainer for motorcycles, cars, caravans, boats, agricultural vehicles, and vans at 6, 12, 24 V with multiple operating modes: once settings are made, everything happens automatically thanks to the internal circuitry that constantly monitors parameters and optimizes current delivery. The automatic battery charger modes are:

• Standard charging with maintenance function (useful during long periods of battery inactivity)
• Fast charging (boost)
• Desulfation (advanced feature that can restore sulfated batteries)
• Vehicle start assist (start)

Complementing all this is the control circuit that alerts you, via LEDs on the panel, to the charging status of the automatic battery charger and any accidental connection errors with the clamps.

A short press on the button with the arrow simply changes the charging voltage selection to match your battery. When the battery is fully charged, Pulse 50 automatically switches to maintenance mode (ideal for keeping batteries charged during long periods of inactivity). To access advanced functions (Boost, Desulfation, Start), press the arrow button for at least 3 seconds. From Boost, you move to Desulfation… and from there to Start mode. The clamps should be connected after selecting the mode; if the battery is very low, it's advisable to perform a pre-charge first.

Why Choose an Automatic Battery Charger?

An automatic battery charger is a must-have for anyone who maintains vehicles or equipment. It simplifies the charging process, extends battery life, and prevents overcharging. Whether you're working on a car, motorcycle, boat, or even a lawn tractor, this charger adapts to your needs. For more home improvement tools and gear, check out our curated selection.
