20A - The battery will be fully charged to 100% capacity in approximately 2.5 hours.
50A - The battery will be fully charged to 100% capacity in approximately 1 hour.
Q10: How should batteries be stored?
Q10: How should batteries be stored?
A10:
We recommend charging the WattCycle Energy battery to 50%. Then, disconnect the battery from the load by removing the negative wire from one battery.
Overall, the battery's capacity loss is less than 3.5% per month at 77°F. However, if stored in extreme environmental conditions, the capacity loss may increase.
