The Backup Battery You Charged Months Ago — 7 Checks Before a Blackout

📚 Rick's Survival Series. DOWNLOAD HERE → https://stan.store/rangerrickus Hey guys! My full guide is on sale now 📖 Grab it here: https://stan.store/rangerrickus A lithium-ion power bank loses about 5% of its charge in the first 24 hours, then a few percent every month after that. Store it full at 104°F for a year and it keeps only about 65% of its capacity. One recalled power bank model, about 1.16 million units, sold for six and a half years before the recall. The Army says to replace lithium-ion batteries 4 years from manufacture. So how much is really left in the pack you charged months ago? Subscribe to the channel: @rangerrickus In this video, we talk about seven checks to run on your backup power before a blackout, including reading the charge gauge instead of trusting the calendar, storage heat and the charge level that shrinks lithium packs, watt-hours versus the mAh on the label, the Army's battery inspection checklist and the CPSC recall list, ports, cables and CPAP runtime math, cold-weather charging limits, and a twice-a-year drain test with dated packs and clear retire rules. If this helped you get your stored power squared away, hit subscribe so the next one finds you. Tell me in the comments where you're watching from and which battery in your house you're testing first. Share this on Facebook, Reddit or your family group chat so someone you love checks their packs before the next outage. You folks are the reason this channel keeps going.
