![]() You want to pay attention to your batteries because you rely a lot on them. How can you take care of your motorcycle batteries? When taken good care of, Lithium batteries can last 5-7 years.Ī conventional battery such as a Lead-acid battery, and an AGM battery, on the other hand, will last 2-4 and 3-5 years, respectively, with good care. What is the life of a motorcycle battery? One or both of them could be the culprit. If it is lower, you might want to consider getting the charging system of the motorcycle inspected along with the battery, of course. ![]() If the battery voltage crosses the 14V mark, then the battery is in good shape. We are trying to check the charging voltage of the battery. Open up the throttle slightly to go above the 2000RPM mark. Scenario 4: Kill switch ON, ignition ON and engine turned ON, and RPM about 2500 However, undercharge on older batteries usually signals that the battery may need a replacement. It is important to note that seeing an undercharged new battery might simply require plugging the battery into a charging system. This could mean one of two things.Įither the battery is not on a full charge, or the battery life is nearly over. However, if the voltage drops to less than 9.5V, there could be trouble. Anything above the 10V marker on cranking the bike would have been ideal. It would be better, of course, for it to be in the 10s instead of the 9s. If the voltage drops between 9.5V to 10.5V with the bike cranked and the engine running, things are still good. Now it’s time to put a significant load on the battery to see how it performs. Scenario 3: Kill switch ON, ignition ON, and engine turned ON and running at IDLE! However, if there is a greater voltage drop, that might indicate a problem with the battery. The voltage should still be in the 12s even though it might be in the low 12s. This should trigger a very slight voltage drop. Scenario 2: Kill switch ON, ignition ON, but DON’T start the vehicle (engine OFF)!Īt this time, the headlight and the electronics will get powered. As long as the voltage exceeds 12.7V, the battery is charged, and things look good. This could be anything higher than 12.7V. Scenario 1: Open circuit voltage, kill switch OFF, and ignition OFF. Now, setup each of the following scenarios: Similarly, the positive terminals of the device and battery should connect to each other. The negative terminals of your measuring device and battery should be connected. To get started, connect the terminals of your Voltmeter or Multimeter to the battery terminals. It is essential to be familiar with the performance of your battery in some common scenarios. How should I test my motorcycle battery charge? Lead-acid batteries’ health can be permanently affected if they get completely discharged. Voltage State of charge Will the bike start Charge? 12.7v + 100% Yes Smart charge ~ 12.5v 75% Yes Trickle or Smart charge ~ 12.3v 50% No Trickle or smart charge < 12V Discharged No Trickle charge Note ? : Besides Lithium based motorcycle batteries, the rest may not fully recover if they get completely discharged. What is the general range of voltage across a 12v battery?įor a 12v battery, here is a table to help understand the range of voltage variations and what each means. Google it and check from a couple of sources.Use the voltmeter or multimeter to check the voltage. ![]() The label on your battery should clearly tell you the voltage. There are several ways to determine the voltage of your battery. How to tell whether your motorcycle’s battery is 6v or 12v? These typically outlast all other batteries but are also more expensive. And it is much lighter than the others and completely maintenance-free. This battery is lighter and can be mounted in any manner, whether sideways or upside down.
