What is the significance of information such as V and Ah on motorcycle batteries?
Maintenance-free motorcycle batteries
Maintenance-free motorcycle batteries (MF) have a sealed design that eliminates the need for fluid topping up and the vent hose. They are easy to care for and minimized gas development minimizes water consumption and reduces self-discharge. The batteries can be installed in any position using fiberglass or fleece mats. They are linked to modern charging technology and are sensitive to chargers for non-maintenance-free lead-acid batteries.
For this reason, older motorcycles should not be equipped with modern gel battery technology. Equipping older models with it is not advisable because the charging curve of the alternator regulator is not flat enough and the gel battery repeatedly receives a violent boost in charging current. On such machines, a sealed and well-maintained MF battery is a better choice.
Lithium Ion Batteries
Lithium-ion batteries are characterized by the fact that they are significantly lighter than other batteries . In the motorcycle sector, acid-free lithium iron phosphate batteries with low risk of fire have prevailed. In addition, they can be charged comparatively quickly and also allow very high charging currents. In addition to the advantage of low self-discharge, they have a long service life. However, such batteries are often not compatible with modern permanent chargers. It is better to connect them to simple chargers with an automatic switch-off, or to use a special charger. Even temperatures below ten degrees are not ideal for such batteries.
Conventional lead-acid batteries are characterized by a comparatively low price. They are associated with more complex care. This mainly refers to checking and topping up the water at least once a month. Older batteries should be checked weekly and the watering interval determined based on usage behavior.
Gel batteries are completely sealed. You can even install them "overhead" in any position. However, it is characterized by very little wear on the electrodes and a longer service life compared to lead-acid batteries. Don't forget: Gel batteries require special electronic chargers. Modern machines with electronic charging current controllers can also be fitted with a gel battery instead of an MF battery.
AGM and pure lead batteries
Comparable to gel batteries, almost maintenance-free AGM/pure lead batteries are primarily characterized by high starting currents. In AGM motorcycle batteries, the acid is bound in a glass fleece. These batteries can be installed in any position, are vibration-resistant and can be charged quickly and with a higher voltage. The higher purchase price is offset by a longer service life.
Which battery do I need for my motorcycle?
Here you can read the difference:
Wet battery: In these batteries the acid mixture (electrolyte) is liquid. These batteries must be filled before installation. This has the advantage that batteries do not age until they are filled. The motorcycle batteries are dry pre-charged at the factory. Instructions for filling batteries are included in the package.
AGM (Absorbent Glass Mat): With AGM batteries, the electrolyte is completely bound in a glass fibre fleece after filling, so these batteries are leak-proof and maintenance-free even if damaged. This technology can be installed upright or lying down up to 45°.
The motorcycle batteries are dry pre-charged when shipped from the factory. Instructions for filling batteries are included in the package.
Pure lead battery: A lead-tin alloy is used in these batteries, which gives these batteries a higher Cranking Amps. The construction is similar to an AGM battery, therefore these batteries are also leak-proof and maintenance-free. These batteries are filled and pre-charged at the factory.
Gel: The liquid electrolyte is bound in a gel by adding silicic acid. Gel batteries can be installed upright and lying up to 45°. These batteries are filled and pre-charged at the factory and are completely maintenance-free. Due to a higher internal resistance, these batteries deliver lower starting power than comparable acid or AGM batteries.

How to charge your motorcycle battery
- The ignition must be switched off for removal.
- Open the battery compartment and first unscrew the negative pole, then the positive pole of the battery.
- Take off the security strap and take out the battery.
- Now the removed battery is thoroughly cleaned with warm water. You can use a stiff brush for this.
- The battery is then dried well and the pole connections are polished with a brass brush or fine emery paper.
- Now the battery is connected to the charger. First connect the positive pole, then the negative pole. If you are charging a lead-acid battery, you must open all of the battery's sealing plugs while charging.
- Now switch on the charger and charge the battery according to the charging currents and charging times specified on the battery. When charging a new battery, take the package insert into account.
- Pay attention to slow charging with about 1/10 of the amperage of the battery or the smallest charging voltage that can be set. You should only use a quick charge in an emergency.
- The battery can then be disconnected again: the negative pole first, then the positive pole.
What must be considered during installation?
- Check whether there is a rubber pad for the battery in the battery box. If this is missing, you can cut such a pad out of acid-resistant rubber. This also counteracts vibration damage when driving.
- Check that the cable connections are clean and free of corrosion. If not, scrape them off with fine sandpaper.
- Write the charging date on the battery and insert it into the battery box.
- For the purpose of good electrical contact and prevention of corrosion, lubricate the screws with a little copper paste.
- Now the plus cable is connected first, then the minus cable. Make sure that you lay the cables precisely and do not kink them too much and avoid chafing.
- Put the protective caps on the connections and close the lid of the battery box.
