Product Description

Yuasa Battery Tender 12V Battery Charger is much more than a trickle charger. It has a brain, is lightweight, compact, fully automatic and very easy to use especially in small spaces. This battery charger will keep the battery fully charged so that it is ready to go always.

It has a microprocessor controlled fully automatic charger and maintainer and is designed to extend the life of any lead acid battery commonly used in automobiles, motorcycles, ATVs, personal watercraft, RVs, boats, airplanes, golf carts, back-up generator systems, etc.

Any vehicle or battery-operated piece of equipment not used on a daily or regular basis is a candidate for a Battery Tender charger. The advanced technology will bring the battery back to a full charge without overcharging and then float or maintain the battery for an indefinite period of time. The Yuasa Battery Tender comes equipped with alligator clips and ring terminals for easy hook up.

Four-Step Charging Process

Step 1: Initialization-Monitor circuit verifies appropriate battery voltage levels and good electrical continuity between battery and charger DC output.

Step 2: Bulk Charge-Constant current at full power. Bulk charge ends at approximately 75% to 80% of full battery recharge.

Step 3: Absorption Charge-Constant voltage at absorption level conditions battery for optimum performance. Absorption charge ends when battery charging current drops below the optimum recharge threshold or the absorption timer expires.

Step 4: Float Charge-Constant voltage at float/maintenance level keeps battery fully charged and maintains high specific gravity. Full charge reset monitor protects battery against excessive appliance current draw while charging. Float charge continues indefinitely.


Automatically switches to float/maintenance voltage after fully charging the battery

Full charger output resumes if the battery voltage drops too far under load

Solid state two-color LED indicates charging stage

Spark-proof even when output leads touch

Short circuit protection

Reverse polarity protection-no charger or battery damage

12' output cord for convenience

Mfr. 5 year warranty

The 12 Volt Battery lightweight, compact size makes it ideal for those hard-to-fit spots. The trickled charger with a brain will assure batteries are maintained after charging and allows ready to go!

Includes one Clamp Harness and one Lug Harness

Optional cigarette plug allows you to charge & maintain your battery directly from your vehicle's lighter socket (only use if socket energized with key off)

Complete 4-step charging program (Qualification, Bulk Charge, Absorption Mode, Float Mode)

Charges/maintains sealed maintenance-free, AGM or flooded lead acid batteries

After reaching peak 14.4 VDC, charger automatically switches to 13.2 VDC float voltage

When voltage drops below 12.6 VDC, charger resumes charging back to 14.4 VDC
