“Once fully charged, how long can the Jackery Explorer 290 generator be expected to hold a charge with NO load? (Or more generally, at what rate will the internal battery drain on its own?)”

• Dear Customer, Thanks for reaching out to us regarding this question. Although the self-discharge rate of lithium batteries is 3% to 5% per month in theory, according to the real feedback of our customers, the Explorer 290 still has close to 95% power after 3-4 months once it is fully charged and with no loading. The feature of stable and high-quality usage is the reason why Jackery's loyal fans trust us. Should you have other questions or concerns, feel free to contact our customer service. Thank you for your support. Best Regards, Jackery Support Team

• The instructions recommend draining the battery at least every 6 months. So I would think it would last at least that long. Not sure.
