Anyone having a motorcycle had to replenish its battery or even jump start it, at least for once. The best motorcycle battery charger is a good solution to keep your battery full and ready for the next ride.
The charger devices differ in price and capacity, as well as in the number of options provided. Some can only maintain a nearly full battery safely through winter, and others can charge the half-dead power bank and even desulfate its plates. More powerful chargers, however, can be overkill for the small motorcycle battery, that’s why charging a motorcycle battery with a car charger might be damaging. We recommend getting a unit intended for motorcycles, for safety and efficiency reasons.
While many chargers are automatic, the other ones include manual controls as well. The majority of the low-cost chargers work with a single type of battery voltage (12V), while others can also charge 6V power banks. Check the charger options we selected for you and make a confident purchase!
Motorcycle Battery Charger Reviews
Battery Tender Junior — Best Motorcycle Battery Charger
The compact two-in-one device made by Battery Tender will fit those who don’t need much capacity but value cut-costing and handy solutions. It supplies 750mA at 12V, which is enough to charge a non-depleted motorcycle or scooter battery within a few hours. It’s also a maintainer so that you don’t have to bother about timely charger disconnection — left connected, it won’t overcharge your battery but maintain its charge at full.
I highly appreciated the non-spark protection in this charger. Connecting it to the battery in the dim light, you don’t have to fear reverse polarity issues as well, as the mechanism blocks the current from flowing. The LED indicator flashes immediately so that you get to know something is wrong. The LED light also shows the status of charging. I used the charger for my AGM battery, while it fits the majority of power bank types including the AGM ones. Due to the smart mechanism, it keeps the battery fully operational without risking to overpower or overcharge it.
This Battery Tender charger motorcycle device implements the four-step charging schedule. During the initial charging stage, it might seem that the charge is too slow; yet, when it comes to a bulk charge, the battery replenishes quickly. The sensors switch the current supply to the floating mode once the voltage is high enough. This keeps the battery operational and I didn’t have to check it the next morning — it cranked on my motorcycle from the first attempt.
- The 80-hour timer turns the charger off for safety reasons.
- Fully automatic charging process.
- The power cord is 12-feet long giving space for a maneuver.
- The plastic cover doesn’t feel sturdy enough to withstand extensive use.

The smart system doesn’t overpower the battery and keeps it charged without feeding more current than needed.
- Can revive a weak battery (requires time, though).
- Doesn’t drain the battery if the power is off.
- The green LED light flashes when the battery is above the 80% level and can be used.
- No turn on/off switch.
- Isn’t water-resistant.
This battery charger for a motorcycle shows the same parameters of charge as it’s a more compact model (also presented on the list). It’s simple to use and doesn’t require any maintenance, provides the charging and maintaining functions for the majority of household and vehicle batteries (though charging the big capacity power banks might take extensive time). It’s made solid and feels like a heavy-duty unit. However, its design (rectangular box) requires a flat steady surface and might become an issue within small garages.
What I noticed first, this potentially the best battery maintainer for a motorcycle works fast and is precise in its battery condition analysis. It immediately recognized my Harley Davidson battery and started to charge it. The device implements the typical Battery Tender signal system, where the flashing green light means the battery is ⅔ full and ready to use. When the charge is complete, the light becomes steady, and the charger switches to the “maintain” operation.
The “maintainer” functionality ensures the charger can be left connected for several days without causing the battery to overfill or overvoltage. It’s also safe for beginners, as the system doesn’t let the current through if the clamps or ring terminals are hooked up incorrectly. There are no sparks if clamps encounter, either.

Features to Consider before Choosing Motorcycle Battery Charger
Before taking the charger with the most options or the highest capacity, or at a bargain price, consider the following issues:
- Power bank type. There can be any type of lead-acid (conventional flooded, gel cell, or AGM) or a lithium-ion battery. The type is important, as these batteries require different voltage supply (about 12.8V for lead-acid and 13V – 14V for lithium-ion ones) and charging framework. If lithium-ion batteries can be discharged up to 80% without losing their capacity, the lead-acid ones might collapse and not accept a charge anymore. Lithium-ion batteries don’t need the desulfation pulsing current used for lead-acid ones.
- Smart options. The smarter your charger is, the more carefully and efficiently it will power up your battery. The smart motorcycle battery tender with microprocessor is preferable, as it analyzes the battery condition and applies the optimal mode of charging.
- Protection. The charger should be safe for you and your motorcycle. The reverse polarity security, the shock-proof design, protection from overheating, overcharging, overloading will ensure your battery won’t get damaged or drained.
- Controls. The majority of the chargers are automatic. However, some models let the user select the needed voltage and the operation mode.
