Seasonal vehicles like motorcycles, ATVs, and snowmobiles often sit for extended periods of time. For the most part, there is little to worry about while they're dormant. However, when you try to use them again, there's a good chance the battery will be dead. A good battery tender will fill the battery and monitor its health during the offseason. Check out the best motorcycle battery maintainers for safe and sustained charging.

Your regular motorcycle battery charger works the same as a phone charger. You plug in your battery, and it continually charges at the same rate until you unplug it. The problem with this way of charging a motorcycle battery is that leaving it plugged in for prolonged periods can damage the battery, waste power, and even be a fire hazard.

A trickle charger was made to replace the standard style and is fairly common today. These chargers use more advanced technology to monitor the charge level and adapt to your battery's needs. The benefit of this "plug and forget" style is that it reduces the unnecessary power waste of traditional chargers and reduces fire risk. The only advantage it has over a floating charger is that no matter when you unplug it, the battery will be fully charged. 

A floating charger, battery tender, and battery maintainer are all the same thing. This is a type of charger that also improves on traditional motorcycle battery charging but uses a different technology than trickle chargers. A floating charger will charge the battery fully, and then shut off. It allows the battery to drain to a predetermined level, then it turns back on and repeats the cycle. This is an improvement over the trickle charger because it saves more power and eliminates the fire risk from continuous charging. The only downside is, depending on when you disconnect it, it may not be at a full charge.  

As the name suggests, this company is a very popular brand that produces the best motorcycle trickle chargers and tenders on the market. The company, Deltran, started out as a small family-owned business in 1965. It became a mainstay in the industry thanks to its state-of-the-art designs and popularity among dealers. Today you can find the company's Battery Tender brand all over the world, thanks to countless vendors and distributors.

The whole point of a battery tender is having multiple charging modes. The least advanced charger has one setting: charge. When you're shopping for a battery charger/maintainer, you want features that will make them worth your while. A trickle charge setting is good because it reduces the overall power that is supplied to your battery once it is fully charged. A maintain charge setting is better because it will completely shut down, charging for periods of time. The best and most advanced tender can offer both options on top of a regular charge mode.

A battery tender won't help you out too much if it isn't compatible with your battery. There are multiple different types of terminals, so pay attention to how the tender will clip onto your battery. The bigger issue may be your outlet options since some battery tenders have shorter chords that might make them harder to use.

Although a simple feature, this can save you from doing severe damage to your motorcycle battery. A common issue is to accidentally connect the cables to the wrong terminal. Instead of damaging the battery, your battery tender will alert you that the connection is incorrect. Reverse polarity protection will keep your power supply and electrical circuits safe from the battery's power.

The best battery tender for motorcycle batteries is the Tender Plus made by Deltran. The company's Battery Tender brand makes numerous products, plus every item from the company has a class-leading 10-year warranty. The Battery Tender Plus gets a boost over its related products (like the popular Battery Tender Junior) thanks to the item's healthy mix of impressive features and affordability.

The Battery Tender Plus is a smart charger, and because of its features, it gives you more flexibility for charging your motorcycle's battery. The Battery Tender Plus will charge your device fully and then adjusts its voltage to maintain your battery. In fact, it uses four separate steps to help keep your battery healthy: initialization, bulk charge, absorption mode, and float mode. This portable motorcycle battery tender also has reverse polarity protection and a temperature monitor that adjusts the output based on your battery’s health.

Despite its useful features, this motorcycle smart battery charger might not be the best for you. At only 1.25 amps, it is a relatively low-powered tender for the price. The Battery Tender Plus also has a basic notification set up with just two LED indicator lights. Some users may not like the lack of controls for turning the device on or off.

A cheap battery tender doesn't necessarily compromise on quality. Foval offers a comprehensive and easy-to-use battery maintainer for a fraction of the cost of its competition. Because of its size, this handheld motorcycle float charger is an excellent choice if space is an issue.

The Floval Trickle Charger is most notable for its affordability, but the included capabilities are no less impressive. The device has a spark-proof lead connection, reverse polarity protection, and automatic charge adjustment. It includes LED indicator lights to inform you of the state of charging and level of power and uses four different levels of charging that adapt to your battery's needs. Many of the customer motorcycle battery tender reviews note that the Floval charge is incredibly easy to connect thanks to its fast grip and versatile connectors.

While this is a great trickle charger for motorcycles, it might not be the best fit for you. This is the lowest powered tender on our list with just 1 amp. While low power is suitable for long-term usage, it all depends on your personal preference and how long you charge. This battery charger and maintainer also lacks some more sophisticated features such as a temperature monitor.

The final motorcycle battery tender on our list is the NOCO Genius, and like the name suggests, it is a smart charger. This tender has even more features than the Battery Tender Plus but the base model has a less amperage. This NOCO charger is the 1.1 amp version, but there are also 4.4-amp and 26-amp options that are more expensive.

This versatile charging device is the best battery tender for ATVs, motorcycles, boats, and even car batteries. Using the Genius for long periods of time can even improve battery life, thanks to its on-board computer. On top of functioning as both a trickle and float charger, the NOCO Genius is weatherproof, spark-proof has reverse polarity protection, and features several LED indicator lights. The 1.1 amp can handle 6V or 12V batteries (with the larger options going as high as 24V), and it is the only battery tender on our list that has a manual power button.

While it might be the best lithium motorcycle battery charger, the Genius does suffer from a few setbacks. The biggest issue is the power, with the smallest option is only 1.1 amp and opting for the bigger sizes comes with a hefty price tag. The power cords are also the shortest, which might make it hard to keep your battery plugged in.

A: There is no best option, but some are better than others. Trickle chargers and float chargers are recommended for long periods of time since they save power and won't hurt your battery.

A: When you're considering the best size battery tender for a motorcycle battery, the answer has to do with the cell. The voltage always needs to match, so 12-volt batteries require a 12-volt charger.

A: Step one: Disconnect the battery from your bike (ground or negative first). Step two: Attach the trickle charger (positive first). Step three: Turn on the charger and let it sit. Step four: Disconnect the charger when it is finished, and reconnect your battery.

A: While trickle chargers reduce the risk of overcharging, it is still possible. Trickle chargers and float chargers still need to checked once in a while and not plugged in for extended periods of time.

The best motorcycle battery available is the Battery Tender Plus 1.25 Amp Charger. This option gives you premium features at an attractive price. 

24v Led Indicator Light

If you're looking for a more affordable option, then the Foval Automatic Trickle Battery Charger is the least expensive option and still keeps your battery protected.
