HOW TO STORE A BATTERY
It’s winter time in the northern hemisphere, and that means for many of us not in tropical locations or dedicated enough for extensive wetsuit riding, your eFoil might be spending more time in storage than the warmer months. Storing and caring for your eFoil battery during periods of inactivity is simple, but important, so we’ve prepared this guide below.
Store your eFoil battery in a cool, dry location. The ideal storage state is at 30-50% of charge. This will lead to the longest life for your battery.
Allowable temp: -10C˚ to 40C˚ (14F˚ to 104F˚)
Ideal storage temp: 5C˚ to 25C˚ (41F˚ to 77F˚)
We recommend to store your lithium-ion battery in a fireproof case. You can buy Zarges Cases on our Website: https://liftfoils.com/product/zarges-case/
As with all lithium-ion batteries, the Lift eFoil battery will slowly lose charge over time while it is stored. If stored for a long (roughly 9 months to several years) time with use, the battery can become over-discharged and lose the ability to be charged at all. To prevent this, and for the longest life of your battery, the battery should be plugged into a charger and charged until reaches 30-50% every 3 months.
To wake up your battery after a long use, follow normal charging instructions, there are no special changes after a long period of inactivity. Remember to first connect the data connector, and then the twist lock, and then plug the charger into the wall.
Before every use, inspect the battery for damage and water ingress. Extra attention should be paid to the enclosure in looking for any cracks in the plastic or areas where the lid may have begun pulling away from the housing (these are potential leak paths). Do not use a battery that has been damaged or you suspect to contain any water.
