The best motorcycle battery charger is a device emitting current in order to replenish the power bank of your bike. The charging units are represented by jump starters and maintenance tenders. Jump starters give a powerful high-amp current to enable an initial spark to the motor. However, such treatment of the battery exhausts its capacity quickly making it non-operational.
The maintenance devices work very carefully sending out the low portions of electricity and causing no immediate damage to the battery. Such units are represented by trickle chargers and battery tenders.
The motorcycle trickle charger feeds constant low current keeping the bank’s level high. It is considered safe, while once the charge is full, the device must be removed in order to prevent overfeeding issues.
The motorcycle battery tender does much the same thing but stops feeding automatically upon reaching the top level. It resumes feeding process as soon as there’s some reduction of the battery volume. It is very handy — and more expensive than a regular trickle charger for motorcycles.

Drawing the Line Between Regular Battery Feeders and Trickle Chargers
The battery chargers warm up the electrolytic liquid and dissolve the sulfate deposits at the battery plates causing the bank to refill. The regular battery charger and the trickle charger differ in:
- Amps and voltage. The regular portable motorcycle battery charger works out the current and feeds it to the battery at the high rate (4 amps plus) and voltage. The best trickle charger for motorcycle always emits small amps at low voltage.
- Time of power charge. The regular feeding appliance enables faster charging than a motorcycle battery trickle charger charger does.
- Battery handling. The ordinary appliance fills even the flat battery and starts the engine almost immediately. The trickle charger won’t do the engine trick and applies to half full power banks only.
- Battery safety. The regular motorbike battery charger must be supervised and disconnected timely to avoid the decreasing and overfeeding of the bank’s capacity. The trickle charger needs less attention, though it isn’t advisable to leave it connected for a long period (unless it is a smart charger).
How to Choose the Best Power Charger for the Motorcycle
Selecting the proper model out of the best battery chargers for motorcycles, follow the steps:
- Define the type. The motorcycle power banks are usually lead-acid (including gel-cell banks and AGM ones), some of the recent models are Li-Ion ones. Many smart feeding appliances can power both types.
- Read the amps and volts. The voltage maintained by the chosen bike battery charger must correspond to the one the battery has. This will ensure its optimal performance and slow discharging. As to the amps, to feed the widespread 4Ah power banks for motorcycle, almost any charger from 0.75 Amps will do.
- Pick the operation. To crank up your motorcycle without much waiting, get a jump starter feeding large amps at high voltage. To restore the power bank upon a long idling, take a regular battery charger. It sends the amps at less rate causing less risk of overheat and damage. To maintain the motorcycle battery condition working so that you could use it anytime, pick the smart battery tender. It will prevent the decreasing of the battery level and keep it fully operational.
How to Charge a Motorcycle Battery. Tips
- Watch the amps. While in some cases using powerful high-amps appliances turns out extremely helpful, it might worsen the battery productivity and span life. For safe feeding, choose the rate equal to one-tenth of the power bank capacity. That is, if your motorcycle bank has 10 amps, charge it at 1 amp per hour and be confident there is no overheat.
- Watch the temperature. While most of the modern chargers can easily operate at low temperatures, not all power banks can do the same without losing their potential. If possible, get your motorcycle battery at the normal room temperature, then start the feeding.
- Give special care to the dead bank. If your motorcycle battery gets flat, do not use the regular high amps to refill it. Feed the half of the usual rate first, until the battery is at least half full. The smart charger will do the trick itself, grounding on its sensor readings.
