Harley Battery Tender: Best Motorcycle Battery Tender Charger Maintainer

You don’t ride your bike during the winter and probably not as often as you would like to other times.  While your Harley is sitting its battery is discharging.  To stop the discharge, maintain your battery at peak efficiency, and make sure it’s ready to ride when you are, you need a Harley battery tender.  A Harley battery tender is one that is specifically designed to charge and maintain lead-acid or lithium batteries like those used in Harley-Davidson motorcycles.

Harley Battery Tender NOCO Genius G3500 Ultrasafe Smart Battery Charger On-Hood ViewWhich Harley battery tender you need depends on a few different factors.  Depending on the age of your Harley, you may have six or 12-volt battery.  What type of battery do you have?  Is it conventional lead-acid, maintenance-free lead-acid, maintenance-free dry charge, maintenance-free Gel, maintenance-free AGM, or one of the newer Lithium Iron Phosphate batteries?

What should you look for in the best Harley battery tender?

Dual Voltage Capability

You may not need a Harley battery tender that can handle dual voltages now, but what about your friends and family.  It’s definitely nice to have the capability in case you need it down the road.  If you have a 6V battery in your Harley, you definitely should consider dual voltages so you can charge and maintain your other 12V vehicles as well.

Fully Automatic

There really isn’t a reason beyond price to buy a manual battery charger maintainer for your Harley.  Plus, you are at risk of losing all of the money you saved and much more if you overcharge your battery by accident.

A fully automatic battery charger is set and forget.  You hook it up to your battery and it does the rest.  It will charge your battery and then maintain it indefinitely at the right charge level without manual intervention and without damaging your charger, battery, or vehicle.

Microprocessor controlled or smart chargers have a built-in computer that precisely controls the charging and maintenance process.

Battery Chemistry

Harley-Davidson batteries come in a variety of types and chemistries.  Make sure your battery type is covered by the Harley battery tender you buy.

We also recommend that regardless of whether you currently have a newer lithium battery or not, you should prepare for the switch to lithium at some point in the future.  Lithium batteries provide more cold cranking amps, are much lighter in weight, discharge more slowly, and will last longer than conventional lead-acid batteries.  The drawback right now is price.  They are also much more expensive.

Safety

You should expect any modern, automatic Harley battery tender to include safety features that protect you, your motorcycle battery tender, battery, and your Harley from damage or injury.  Minimum safety features to look for include reverse polarity protection, spark-proof connections, and overcharge protection.

 

 

 

 

 

Battery Conditioning and Repair

Some models are capable of actually repairing your battery damaged by sulfation causing low-voltage or lost capacity by using a high-voltage pulse charge.  They can also stabilize your battery’s internal battery chemistry for increased performance and longer battery life.

Warranty

When a Harley battery tender manufacturer provides a long warranty on their equipment, they are telling you that they have faith in their materials and workmanship.  Look for at least a 3-year warranty on any Harley-Davidson battery tender you buy.

We searched battery forums, motorcycle forums, manufacturer sites, social media, consumer sites, retail sites, and customer review sites to find the most popular and highly rated battery charger maintainer.
