Rather than spending your free time browsing through your many options, check out our narrowed-down list. But first, you should know what details to look for.

Battery Tenders vs. Battery Maintainer vs. Battery Charger

Before you get confused between battery tenders and battery maintainers, you should know that they are both referring to the same thing. They both complete the same job, which is charging up your battery and keeping it at that ideal level. Actually, the name battery tender comes from a brand name and has simply become common terminology.

However, a battery charger is something different. The charger will send a constant charge to your battery rather than maintaining it. Using a charger instead of a tender can overcharge your battery, which will damage it over time.

Performance & Reliability

Finding the best battery tender for motorcycles for you has a lot to do with identifying which products are the most reliable. Without your battery, your motorcycle won’t run. And replacing a battery is no cheap feat.

The best of the best will keep your motorcycle battery at optimum levels with the ability to sense charge levels as well as temperatures that can damage your battery.

Additionally, the best-performing tenders have easy-to-read indicator lights and displays that will let you know the status of your battery. Premium models use LCD screens to give you additional status info.

Finally, safety is key with any vehicle accessory. The best battery tenders for motorcycles have protective features such as spark-proof connectors, reverse polarity protection, short-circuit protection, and overcharging protection. You might also find a tender with automatic voltage detection.
