Partially discharging about 10-15 percent of the battery’s capacity and recharging is terrible for its health. When recharging, it’s always best to recharge the battery to its total capacity. Ideally, a lithium battery will discharge 50-80 percent of its capacity, or more for some units, before recharging. Not Sufficiently Discharging the BatteryĪ lithium battery has many charging cycles in its lifetime, and it’s healthier for the battery if it’s discharged and recharged sufficiently. Pro Tip: Need to charge multiple lithium marine batteries at once? Consider a multi-bank charger that can sufficiently charge numerous batteries at a time safely. If the charger’s Ah rating is higher than the battery, it could harm the battery severely. When charging, ensure the amp hour (Ah) rating of the battery charger isn’t higher than the Ah rating of the lithium battery. It may seem obvious, but owners forget all the time to check a charger’s voltage before hooking it up to their battery. Using a Charger With the Wrong Voltage/AmpsĪlong with using a lead-acid charger with a lithium battery, another common mistake is using a charger with an incompatible amount of voltage or amps.

Pro Tip: Before purchasing a charger, read the manual to ensure it specifies it’s compatible with the lithium battery you plan to pair it with. It’s always recommended to use an onboard lithium battery charger for a lithium battery not only because it’s safer but because it’ll help charge the battery faster. If a lead-acid charger reaches a voltage level a lithium battery can’t handle, it could permanently damage the battery. Obviously, a lithium battery charger is better suited to a lithium battery. While it’s possible to charge an ionic lithium battery with a lead acid charger, it comes with a risk and is generally not recommended unless it’s the last option. One of the most common mistakes new owners of marine lithium batteries make when charging is utilizing the wrong charger.
