Table of Contents
Having the right battery charger for your Harley-Davidson is important to ensure that your battery survives the winter, or rather, as many winters as possible.
Das wird den Meisten von uns schon passiert sein, irgendwann im Herbst hast du deine Harley-Davidson in der Garage abgestellt, schรถn Winterfest gemacht und denkst, alles ist gut. Im Frรผhjahr soll es wieder losgehen und sie gibt beim ersten Startversuch, keinen Laut mehr von sich.
An active alarm system consumes electricity.
What could have happened is that either the alarm system has drained the battery over time, or your battery couldn't cope with the cold. It may be suffering from old age, or it may simply be broken. There could be other reasons for the failure; at some point, they simply wear out. However, if you treat them well, you can extend their life by several years.
Of course, it always depends on the circumstances, but some of the following tips are generally quite useful.
- Simply remove the fuse โ but then the alarm system will no longer be active. Cold weather can still affect the battery.
- Remove the battery and store it in a warm, dry place.
- However, a battery is recommended. Battery charge maintenance device
- When purchasing a replacement starter battery, ensure it is of high quality with a high starting current.
In my experience, when you ask around among your friends, they usually recommend an original Harley-Davidson AGM battery, which has high starting power and enough power to bring the V2 back to life. When it comes to alternative batteries from the accessories range, some people use Yuasa or East Penn batteries. You really shouldn't skimp on the battery, as they tend to fail when you least need them to, so you should really pay attention to quality here.

Why choose the Harley-Davidson charger?
The advantages of the Harley-Davidson battery charger
You can use the charge retention function Not only do they ensure that the starter battery does not discharge over the winter, but they also extend the life of your battery by years. Other chargers can certainly do the same, but as I have just discovered with the Pan America, although there is a plug for conveniently connecting the charger, this only works with Harley-Davidson chargers. This has to do with the CAN bus, which recognizes what kind of device is connected to the SAE plug.
Harley-Davidson battery charger plug (SAE plug)

You cannot supply power to the battery via this connector unless you have a compatible device. The only alternative is to lay a separate cable to the battery. For my part, I now have the right H-D charger, which I currently have connected to my EVO so that I don't have to worry in the future if I want to connect a newer model Harley-Davidson to the charger.
After all, Harley-Davidson even offers a 5-year warranty on the 1-amp battery charger. Now I know myself what it's like when you don't have the operating instructions in your head, so I'm happy to list the information below.
What's included โ Unboxing
- Multilingual operating instructions, including German.
- Pole terminals fused with 2 amps on SAE plugs, total length approx. 60 cm
- 1 amp Harley-Davidson battery charger with SAE plug, total length approx. 2.25 m
Caution: Do not simply connect the charger; read first!
It may not seem like it, but even small chargers need to be used correctly to avoid damaging the battery.
The Harley-Davidson 1 Amp Battery Charger has six (6) modes: Standby, 12V, 12V AGM, 12V LITHIUM, 6V, and Force. Some charging modes must be pressed and held for three (3) to five (5) seconds to activate the mode. These press-and-hold modes are advanced charging modes that require your full attention before selection.
It is important to understand the differences and purposes of each charging mode. Always check with the battery manufacturer to confirm the correct charging mode for the specific battery that is installed. Only start using the charger once you know the correct charging mode for your battery and you are absolutely sure what type of battery you have installed.

How long does a battery need to charge?
Under normal circumstances, with a suitable battery charger, an intact battery takes approx. 12 hours to charge sufficiently.

A Harley-Davidson starter battery should have sufficient starting power. Harley-Davidson engines generally have a large displacement, which requires a lot of power, especially when cold.
Why choose an AGM battery?
Electrochemical processes take place in batteries. Electrolytes transport the electrical charge. An AGM battery binds the electrolytes in a glass fiber fleece.

AGM batteries do not leak and can withstand tilting.
How long does a battery usually last?
With proper care, it is not uncommon for batteries to last longer than five years. In Harley Site Facebook comments, there have been reports of batteries lasting as long as 12 years with proper care and a battery maintenance charger.
Avoid deep discharge
One of the greatest dangers for a battery is when it is deeply discharged. This can happen when consumers continue to run during long periods of inactivity; digital clocks and alarm systems in particular are known for this.

What should you do if you don't have a 220-volt connection nearby? Optimate, for example, offers a battery charger that has a DC-DC connection. The OptiMate DC-DUO 12V 2A The charger can be connected to a car battery and then used to charge a motorcycle battery.
