A motorbike is a great joy, especially when it starts properly: fast, without issues and in any condition. To get that benefit, the rider must ensure that the best motorcycle battery suiting his or her needs.
Apart from ensuring the quick “weatherproof” start, the motorcycle battery must provide other positives resulting in a comfortable less-maintenance use and reliable long-lasting performance. When go shopping, consider the following features:
- Size. The power block must fit the intended seat in the motorcycle. It can be smaller if the relevant spacer appliances are supplied. The battery should be firmly fixed in its compartment.
- Power. The voltage, cranking amps, and cold cranking amps must be within the limits indicated in the motorcycle specification. More cranking amps means faster engine start in warm weather, while cold cranking amps are responsible for activating the engine in the cold.
- Positioning of the battery and its posts. Depending on the power bank type, it can be put in a horizontal way only (conventional power blocks) or allow for angled and vertical positions (Gel Cell, AGM, Lithium-ion models). Another concern is the accessibility of the battery posts. The terminals must reach and fit well to the posts.
- Service life. When estimating the service term of the battery, consider the conditions required to keep it operational. Climate, operation mode, and maintenance affect the duration considerably.
Now, balance the crucial factors and pick your motorcycle battery!

How to Test a Motorcycle Battery Properly?
There are three main reasons to charge a motorcycle battery:
- It came flat from the factory and must be charged before use — most likely, a trickle charger will be required for initial bulk feed.
- It stays idle for a considerable time and needs a maintaining charge in order to preserve capacity and voltage — a floating feeder or a smart one should be used.
- It went dead unexpectedly and must be revived — it’s advisable to use a smart or floating charger; yet, they might be ineffective for completely empty power banks.
In each of these cases, the different tactics and different types of chargers will be used. However, the way of charging and the relevant appliance also depend on the type of model itself:
- Conventional and AGM lead-acid batteries can be powered up by different types of chargers.
- Gel batteries are safe to charge with the floating or smart chargers.
- Lithium cells require their own chargers, while some can use conventional appliances.
Once you’re clear about the battery and charger type, take the following steps:
- Disconnect and take it out the (unless planning to maintain it on a floating / smart feeder). Do this to prevent bike electronics damage and possible leak / explosion.
- Examine the battery. If there are acid spots or hard scratches on the casing, contact the dealer / specialist.
- Connect the charger leads. Make sure the terminals fit (+ to +, – to -).
- Plug in / turn on the charger and supervise charging at least through the initial stage.
- Disconnect the feeder once the battery is full / at the end of the maintaining period.
How Many Volts is a Motorcycle Battery?
The standard motorcycle battery is listed as a 12V power bank. However, this refers to the current it feeds. The battery itself should have no less than 12.8V when fully charged. Still, the discharge and voltage do not correlate in a linear way. For example, if the voltage drops to 12.5V, it means the cell is half-full and needs recharging.
If the voltage doesn’t fall below 12.0V, it is still operational but should be fed as soon as possible, since further discharging might lead to sulfation and capacity loss. In case the voltage is less than 12.0V, it might decrease the cranking power and hold the charge worse than before. If it drops below 10.8V, the battery could be revived, but most likely, for one cycle only, upon which it becomes non-operational.
How Long does a Motorcycle Battery Last? A Quick Overview
The manufacturers state different periods of service life for their batteries. This depends on the cell type:
- Conventional cells. Last about 3-4 years, 7 if used correctly.
- AGM. Have a longer life, about 5-7 years.
- Gel. Can last up to 10 years.
- Lithium. Can reach as much as 15 years (by advertisement).
The life of the actual battery can differ since many factors affect its operation and period of work:
- Usage. Constant usage prolongs service life.
- Weather. A mild climate without much heat is the most preferable.
- Maintaining. Batteries maintained through the idling period serve longer.
How to Test a Motorcycle Battery Properly?
Testing of the motorcycle battery depends on their types. The following tests can be performed:
- Estimation of specific gravity. This can be done for conventional lead-acid batteries by hydrometer. The power bank should be fully charged before testing. Readings of 1.265-1.280 show a full battery.
- Voltage estimation. Sealed lead-acid and lithium batteries can be tested for voltage level. For that, various appliances are used (voltmeter, conductance tester, etc.) The readings should be fixed in the open-circuit test and then compared to the ones get after the short engine work and idling period (about 10 minutes).
