Bates BattBoy HM5
Bates BattBoy HM5
Modern gel or Li-Ion batteries offer a significant advantage - they are leak-proof. Those who ever experienced spilled acid in their horseshoe oil tanks will highly appreciate this fact. On the other hand, owners of classic bikes do like the looks of their original energy store and the corresponding cover and mounts. With a Bates BattBoy Battery Box you can have the best of both worlds, because what looks like a period type HM5 6V accumulator on the outside can house a safe, modern battery within. Just hook it with two eyelet wires to the terminals on the bottom of the lid and you are all set. Perfect for 6 to 12 volts electrical system conversions, too. When using suitable Antigravity versions you even have some storage room left for a few small spare parts, safety vest, Cuban cigars, etc. Ain't this one heck of a cool solution for an old problem?

Cannonball LION Battery Boxes
Cannonball LION Battery Boxes
Our electric start system just got even more stealthy.
The Cannonball Stealth Starter can give classic Harley Big Twins (with rigid or swingarm frames) the almost invisible option of starting by pushing a button. For reliable operation this system needs a powerful 12V Li-Ion battery, a solenoid, additional wiring and circuit breakers. To avoid an unsightly mess we developed this solution that incorporates everything inside a humble looking Harley HM5 battery case. From the outside it’s as stock looking as the 6V original, but the electrics inside are state of the art. In the two compartments there’s room for a 12 cell Antigravity Li-Ion battery and all necessary electrical components. A stock like lid looks as innocent as the vintage acid lead battery it replaces.

OEM Low Maintenance AGM Batteries
OEM Low Maintenance AGM Batteries
AGM (Absorbent Glass Mat) batteries offer quite a few advantages compared to standard motorcycle batteries. They are leak-resistant, the sulfuric acid is bound in glass mat fleeces between the plates. They are sealed and can be installed tilted by 45°. During normal use they will not gas, so there's no destilled water to be refilled. Due to their construction they deliver about 1/3 more cranking amps than their "wet" brothers, which you have to check for fluid level often. These batteries are not perfect though: whenever your mount is left unridden for a while, you have to maintain them by a charger.

intAct Bike Power HVT AGM Batteries
intAct Bike Power HVT AGM Batteries
Intact HVT batteries were specifically designed and developed for the harsh conditions found on motorcycles - extra sturdy and highly shakeproof. They can be installed tilted up to 90° thanks to their almost maintenance-free and leak proof construction. They meet highest levels of cranking and staying power. As always, there is a little fly in the ointment. As voltage drops below 12V during storage times, the batteries have to be recharged - urgently. So if you're not driving your bike frequently, plug your charger in, frequently. Our HVT batteries fit OEM applications.

intAct Bike Power HVT Gel Batteries
intAct Bike Power HVT Gel Batteries
HVT gel battery means: You get a charged and ready-to-use battery delivered. Modern technology ensures that the plate packs are packed very tightly and fitted precisely into the cells. The gel-bonded electrolyte makes the battery leak-proof and it can also be installed at an angle (up to 90° is possible). The cold start currents are much higher compared to similar batteries and the battery is very vibration resistant. The HVT gel batteries are maintenance-free. In spite of all these advantages and positive characteristics, we recommend disconnecting the battery during longer idle periods and checking the charge status every 2 to 3 months. Those who do not want to or cannot disconnect the battery because of an alarm system should check the state of charge once a month and recharge.

Original replacement batteries

do not necessarily have to come from Harley-Davidson. But selection criteria are clear: same size and dimensions, to be mounted in the Softail, Dyna, Sportster or FLH as the original, plus and minus pole in the same position on the housing and as identical as possible values in terms of cold start current and capacity. Of course, we are happy to "accept" better values.

How do I find the right battery for my Harley?

If you know the original spare part number, you have a clear advantage. Searching by model and year of manufacture is of course also possible, if you can assign this exactly. If this is not possible, determine the dimensions and look at where the poles are located and what other designations are found on the battery. This will give you a good result in your search for the right energy source.

We give here in the store with all batteries the original spare part number as a reference, plus the whole list of Harley models in which the battery fits and of course the dimensions.

I have a classic wet lead acid battery. What do I have to take into account?

Before installation, it must be filled with acid up to the mark. When filling, air bubbles often form between the plates. These can be loosened and exited by gently shaking the battery. Then refill with acid up to the mark. When the acid has settled, charge the battery for about three to four hours without cell plugging. This charging is important because otherwise the battery will never have all its possible power. In addition, the life of the battery will be shortened. Only then screw in the plugs, attach the overflow hose and install it.

Regularly check the acid level and add distilled water as necessary. If the battery constantly has too low an acid level, the regulator must be checked. In fact, there are quite a few regulators that overcharge the battery at higher speeds.

If the motorcycle is not used for a long time, disconnect the battery and check the voltage every 4 weeks or so. If the voltage drops below 12.6V, it needs to be recharged.

I have an AGM or a gel battery. What is the best way to treat it?

The battery comes ready filled and sealed. We make every effort here to always ship the batteries from our warehouse fully charged. Nevertheless, we recommend charging the battery for about an hour before installation.

About every four weeks check the voltage. If the regulator and alternator are OK, a battery should have about 12.7-12.8 V as long as the ignition is off. If it often has less, you drive too many short trips or you would have to check the regulator. From 12.6 V or less in any case recharge the battery. Disconnect the battery for longer periods and check the voltage from time to time as usual. Recharge if necessary.
