1 ， the lithium battery Warranty:
Since the lithium battery is a consumable item ， please check the battery use after receipt of the goods is normal . And regulate the use in later use， protect the lithium battery is strictly prohibited without the net electricity consumption ， there are more than sure to keep the battery power to charge . Just do not run out of power on long-term use ， because the battery without memory function ， there was no life limit ， once the battery is depleted batteries scrapped ， whether with protection battery， if left unused for a long time ， then ， we need to charged save ， otherwise may cause the battery self-discharge broken . Receipt of the goods within 24 hours if no problem ， I will be considered normal ， over 24 hours of battery problems found will not give warranty ， please be sure to pay attention to the customer !
