1. Ideally, use and store the product between 20°C ~ 30°C (68°F ~ 86°F), and always keep it away
from water, intense heat, and sharp objects. Do not store in temperatures above 45°C (113°F) or
below -10°C (14°F) for an extended period.
2. Storing a battery with a low charge for a long period shortens its lifespan. DELTA 2 mitigates the
damage by putting the battery into hibernation mode. To get the most out of the battery, make
sure it is about 60% before putting DELTA 2 into long-term storage, and then once every three
months, discharge the battery to 30% and recharge it back to 60%.
