Charging a Norsk Lithium Battery

My Helix 7 came with the 15 amp hr. Norsk lithium battery. Should it be charged until the display on the battery reads 100% or should the light on the charger turn off, or green, etc? No charging instructions with the battery or with the Helix for this battery.

Thanks.

Until the charger says it’s done

So that means the charger light turns off/turns color?

green light should mean it’s fully charged. red light should mean its still charging. that’s the way my regular and lithium battery chargers work.

Thanks guys. That’s what I thought, but the on-battery display will say 100% charged for an hour or more while the red light on the charger stays on. I’ll give it a bit longer and see if the light changes.
