    Maintenance-free batteries are prefilled and sealed

    • They are factory activated (partially precharged) and always need to be fully charged with a suitable battery charger.
    • They do not have to be filled with acid and must never be opened by force and acid added, as they have already been prefilled (acid absorbed in fibreglass mat). They are ready for installation apart from charging.
    • These batteries will remain maintenance-free for their entire life and must not be opened by force under any circumstances.
    • It is strictly forbidden to add distilled water or acid, as this would destroy the battery.

    Additional benefits:

    • Battery fluid is bound in a gel substance
    • Hermetically sealed and leakproof housing
    • Superior cranking power compared to conventional batteries
    • Minimal self-discharge
    • Extremely long service life
    • Can be installed in any position
    • Includes bolts, nuts if necessary, and detailed operating instructions

    DELO Gel HD batteries are designed to operate with up to 14.35 V alternator charging voltage, which means they can very often be used as a replacement for standard or AGM batteries (ask your local dealer)! Over the winter, it is sufficient to connect the battery up to a charger once every 4 to 6 weeks.

    Please observe the following instructions, which will save you the hassle of push-starting and other unwelcome surprises. If you are having trouble finding the right battery for your vehicle, please use our product listing in the "Bike database" (top navigation bar)! As a general rule, the motorcycle manufacturer specifies the right type of battery for your motorcycle. If you're unsure, simply take a look in your owner's manual or check the label on your old battery.

    • What you should also know about Gel HD batteries:

    Maintenance-free gel batteries are completely sealed. This type of battery is precharged but requires a top-up charge before installation, for which only special chargers ??? like the ProCharger series may be used.


    Before installation, please check that the battery fits your vehicle (size); the terminals are in the correct position, and the voltage (V) and capacity (Ah) are correct. Please carefully read the package insert and the safety instructions it contains!
