Never charge a Fulbat lithium battery with a lead acid charger including a desulfation program. Irreversible damage to the battery will occur.
Never maintain the lithium battery during a long period. Lithium batteries don’t support a trickle-charge in the way a lead-acid battery does.
We recommend you to make periodically a 30 minutes charge (every two months).
Never charge the battery with a high current than 2C (2C corresponds to 2 x the battery capacity). This is the MAX charging current accepted.
To maximize the battery lifespan, ensure that the charging time doesn’t exceed 30 minutes while charging at the maximum current even if the battery is completely discharged.
