Choosing a High-Quality Motorcycle Battery Charger

Usage/Frequency

Will you be charging your motorcycle on the go or at home in your garage? Many of the best rated motorcycle battery tenders and chargers can be used in multiple places; you still want to ensure you will be able to have that flexibility. A compact charger might be ideal if you plan to use it on the go more often than at home.

Battery Charger Type

The motorcycle battery jumper feeds a lot of amps to the battery quickly so that you can get on the road. In comparison, the motorcycle battery maintainer is used between rides to ensure the power levels remain where they need to be. You can also choose from a trickle charger or a float charger to maintain levels. However, you will want a smart motorcycle battery charger if you don't want to overcharge the battery accidentally. 

What Kind of Battery?

Not all motorcycle battery trickle charger options will work with all battery types. You need first to figure out what kind of battery you have. You might have installed a lithium, lead-acid, AGM, or flooded/wet cell battery. Some will work on multiple formats, but you may also need a dedicated lithium motorcycle battery charger.

Power Supply

The best battery charger for a car and motorcycle must plug into the appropriate source for operation. Will you be using AC or DC power to charge the battery? A portable motorcycle battery charger might offer the option to use either power source, but this feature does cost more and might not be worth the extra expense.

Charger Size, Amps & Voltage

The best battery tender for a motorcycle battery must operate on the appropriate voltage your equipment contains. Most motorcycles come equipped with a 12V battery, but it’s not uncommon to find a 6V model as well. If you use the incorrect voltage to charge the battery, you can cause damage.

Compatibility

You might want the best battery tender for a Harley Davidson motorcycle today, but what if you decide to purchase another bike down the road? You can find a motorcycle battery charger tender that works on multiple models to provide more compatibility. Read through the specs of the charger you are looking at to ensure it will work with your battery.

Durability & Versatility

You might be using your motorcycle battery jump starter in extreme temperatures. If this is the case, you want to make sure it can withstand the additional abuse. Otherwise, it won't be worth the cost. Look for a battery charger that features durable construction and offers plenty of versatility. 

Charger Features

If you want to get more for your money, look for additional features that add value. For example, your charger might also have the option to operate as a motorcycle battery tester. Read what charging modes are available and look at the various connectors. You should also examine the continuous charging amps and look for starting/crank assist.

Safety Features

You want to be safe while using your portable motorcycle battery charger, but not every model comes with advanced safety equipment. Look for options, such as spark resistant clamps, reverse polarity features, an LED display indicator and short circuit protection. Each of these elements might add more to the cost, but will keep you protected.

Price & Warranty

If you want a cheap motorcycle battery charger tender, you will be able to find one. However, will it be worth the cost if it doesn’t work as you need it to? Instead, when you ask yourself - what is the best motorcycle battery charger - focus more on the value than the cost. You want a charger that’s going to withstand abuse and last many years. You can also evaluate the warranty term to ensure you gain the protection you require.
