3/5/2023 0 Comments Battery buddy for harley![]() If you need to replace your battery and you decide to go with a standard 12-volt battery instead of an AGM, your Harley-Davidson will still function. However, the AGM batteries used in Harley-Davidson motorcycles are made specifically for them. AGM batteries are used in other types of bikes, especially those made by European manufacturers. These particular batteries are specifically designed to be used in Harley-Davidson motorcycles. If you’re curious to know more, the AGM battery is an absorbent glass mat variety that is designed to stand up to the types of punishment that modern-day motorcycles typically put a battery under. That said, you’re a lot more likely to find one on one of the newer bikes than you are on something that’s been around for a few years. As a result, some Harley-Davidson motorcycles will indeed have an AGM battery, but that isn’t true in every case. After they factor everything in, they decide which option will work the best and then go from there. It all comes down to engine size, the amount of electronics included on that particular bike and the room that they have to place the battery. In fact, they choose the battery carefully based on the specific needs for that motorcycle. It’s important to remember that the motorcycle manufacturer doesn’t use the same battery for every motorcycle that comes off the assembly line. In some cases, it does but that isn’t always the case. ![]() You might have heard some talk that your Harley-Davidson motorcycle has what is frequently referred to as an AGM battery. As a result, Harley-Davidson switched to a larger battery with more volts so that the battery could do its job more effectively. ![]() Why did Harley-Davidson switch to a battery with more volts? As technology has improved and more electronics have been included on motorcycles, it has essentially become almost impossible for a 6-volt battery to successfully operate the motorcycle. On the other hand, anything made after that time is going to use a 12-volt battery. If you’re riding a classic that was built before 1965, your Harley most likely uses a 6-volt battery. All Harley-Davidsons use either a 6-volt or 12-volt battery. If you’re wondering how many volts your battery is for your Harley-Davidson, it’s relatively easy to figure it out. If an external load is applied to the battery while the charger is in Step 4, Float Charge, and if the battery voltage drops below a range between 12.0 to 12.5 VDC, then the charge cycle will restart.3 Lithium Batteries How Many Volts is Your Battery? Maintain fully charged battery at 13.2VDC float voltage. When battery-charging current drops below 0.1 Amp or until 6 to 8 hours have elapsed, will transit to Step 4, Float Charge. Holds voltage at 14.4VDC and forces current to fully charge the battery. When battery voltage reaches 14.4 VDC, will transit to Step 3, Absorption Charge. Then current drop gradually until voltage reaches 14.4 VDC. Now you will know if batteries need replacing without guessing.Ĭonstant current at 1.25 Amps to raises battery voltage to be approximately 80% recharged. Qualification check to ensures safety by verifying battery status prior to charging. I try not to let my battery go more than a month without being charged.īattery Fighter® ’s 4-Step Constant Current Charging Program: I always disconnect it when it reaches "maintenance mode" (referred to as "float charge" here). I have been using a "Battery Fighter" (odd name) charger. I had AGM batteries in my Yamaha for the past 10 years and they last several years with proper maintenance. The thing about AGM batteries is that you should never let them go completely dead.
