Some customers get 3 nights on a single charge, others get less than one night. The battery runtimes will be different for each person. If you need more runtime before recharging, we suggest a dual battery set up. This will allow the first battery to run until it is empty then the second one will kick in and take over automatically. Also using a low-med setting helps the battery last much longer. Shipping Information: Most orders shipped same day from California.
