Yuasa 3 Amp Automatic Lead Acid & AGM Battery Charger/Maintainer/Tender

Yuasa has been building motorcycle and powersports batteries in Reading, PA since 1979, so it makes sense to keep a Yuasa battery healthy with a Yuasa charger. The 3 Amp Automatic Battery Charger & Maintainer has more than twice the output of a typical motorcycle tender, so it brings a low battery back up faster, then switches itself to maintenance mode and holds it there for as long as the bike sits.

It uses an OEM-approved 5-stage charging algorithm with active desulfation to help recover batteries that have started to sulfate from sitting, and it checks for a defective battery or a reversed connection before it starts. LED lights show standby, charging, 75% charged, fully charged and defective battery status at a glance.

For 12V lead-acid, AGM and gel batteries only. It is not designed for lithium batteries. If you run lithium, see the Yuasa 900mA charger below.

Key Features

• 3 amp output: faster charging for motorcycle, ATV, UTV, snowmobile and personal watercraft batteries, with maintenance up to car-size batteries.
• OEM-approved 5-stage charging: faster and more energy efficient than a basic trickle charger.
• Active desulfation to help recover sulfated batteries.
• Automatic maintenance mode: switches over once the battery reaches peak voltage, designed to prevent overcharging.
• Defective battery and reverse polarity detection, plus a warning if it's connected to the wrong battery voltage.
• 13 ft total cable length including the alligator clips.
• Mounting holes for a permanent spot on the garage wall or bench.
