Cover Image: The Best Battery Tenders for Your Motorcycle

A battery tender can take your charging process to the next level. The right choice will maintain a balanced, safe charge level and help keep your motorcycle operational, fresh, and efficient over the years. This article will help you find the best battery tender for your needs.

Before deciding you need one, it’s a good idea to know exactly what a battery tender does. This charging device will connect to a standard outlet, then charge your motorcycle’s battery “intelligently.” It does this by transferring power while it keeps a safe charging level.

As time goes on, batteries lose their internal charge. So battery tenders are a must if your motorcycle is left inactive over long periods of time, such as the winter months. The main job of a battery tender, however, is to “tend” your motorcycle when you’re away.

Battery tenders have circuitry controlled by microprocessors, along with internal sensors, enabling them to consistently check and change the level of your battery’s charge as needed. Trickle chargers have been known to fry batteries and are now considered outdated technology, so many prefer a tender. Once you know the difference between a trickle charger and a battery tender and choose to purchase the latter, it’s time to look at some different products.

CTEK (56-158) MULTI US 3300

Do you often have to leave your car or motorcycle in storage? Then a solution like this CTEK MULTI US 3300 tender is a must for you.

Many vehicle owners are familiar with the event of their battery discharging after having their car or motorcycle sit for a while, then having to use a charger to restore the voltage.

This is not only time-consuming but unpleasant, especially when it’s cold outside. This tender will do all the necessary work and is also easy to use.

“This 12V battery charger can take multiple types of lead acid batteries installed in different types of vehicles and other home accessories such as a lawn mower,” said Alex at Battery Chargers Expert. “You just have to have it ready to use and you can put it to work whenever you want it so.”

This 12-volt tender will help your motorcycle crank immediately without causing you to lose your radio settings or have to reset the clock, since your battery will be charged up. There are a couple of different modes included that allow you to select when it’s cold weather. This charges the battery to the right voltage, then automatically turns off. This setting can be used for vehicle batteries, ATV batteries, and motorcycle batteries stored in cold weather.

In addition, there’s an indicator included that will tell you how the battery is doing, whether it’s charging or charged, and will alert you if the cables have been incorrectly connected. The connection terminals and power cable are conveniently long, making it easier than ever to reach power outlets. It also comes with a bag for storing cables and the device itself.

This CTEK MULTI US 3300 battery tender is suitable for anyone who lets their vehicle sit for weeks at a time but still wants to have a fresh battery once they start it up. This automatic device is a 4-step tender, very compact, versatile, and useful for maintaining all of your vehicles. Just plug it in, forget it, and go about your day.

As soon as you’ve switched the device to your preferred setting, the charger takes some readings and starts charging your battery. As soon as this phase is complete, the tender switches into maintenance mode. The charging process uses patented pulse technology which is considered, by some, to be the most caring method for long-term battery connections.

When batteries haven’t been used, they lose their strength and sulphation happens, shortening their life. Once a battery is sulfated, it’s harder to charge. This tender has a method built to recondition batteries in this condition. It is often able to recover and save the battery’s power once it has analyzed the current state of it. These charges have been built with user safety in mind and are spark-free, offering a safer, easier connection.

In addition, they’re short circuit proof and safe from reverse polarity. This helps to keep your vehicles’ sensitive electronic components free from harm. In the event that you accidentally connect the battery backward, this product will alert you with a red light and hold off on charging until you’ve properly hooked it up. Use it for tractors, lawn mowers, boats, RVs, and even vintage vehicles in addition to cars and motorcycles. It was designed especially to suit a wide range of needs, batteries, and vehicle types.

3 Basic Battery Tender Tips & Instructions

Battery tenders can be used to maintain golf carts, ATVs, motorcycles, cars, and more. Just plug one into a standard outlet to charge and go about your day as it stays at the perfect level.

Although a battery tender can charge car batteries and more, equally important and impressive is the way it maintains and repairs batteries. Modern products for this can often handle maintaining and charging both lithium-ion and lead-acid batteries. This section will focus mostly on the latter.

  • Charging and Testing: Modern tenders are usually controlled by a microprocessor, using multi-step programs of charging to maintain, repair, and charge the battery of your vehicle. A lot of them can be set and then walked away from without an issue, performing their necessary functions without intervention from you. This can be especially helpful and convenient for those who need to store their motorcycle over the cold months or only use it sometimes.
  • Proper Battery Storage: To lengthen the life of your vehicle’s battery, you should make sure you know how to properly store it when it’s not being used. To do this, disconnect its cables, starting with the black negative cable and then the red positive one. Check to make sure there’s no damage or leakage to the battery case, using goggles and gloves as protection. If you find any corrosion, remove it with baking soda. Check each cell for their electrolyte levels if your battery comes with filler caps, and fill the cells if they are low with de-mineralized, de-ionized, and distilled water.If necessary, charge the battery and check the electrolytes again once it has cooled. Take the battery out and store it somewhere dry, but ideally not somewhere that it could freeze. Connect a float or smart charger to maintain the battery charge while it’s being stored. Ask a professional or check the manual, when in doubt.
  • Using a Battery Tender: Most batteries allow you to simply plug the charger in, hook the leads up to the terminals, and start it up. Plug the charger into a regular outlet and ensure that the leads are connected to the right terminals. As always, connect black to black and red to red. Some tenders will come with reverse-polarity protection and will warn you if this is done incorrectly.

As always, when you are using your vehicle and any related components, always be safe and pay close attention to what you’re doing. Taking proper care of your items will ensure they last as long as possible.
