Follow these steps to store your power station safely for months, from choosing the right charge level to temperature control and periodic battery checks.
Quick answer
For long-term storage, keep your power station at a partial charge—around 50–60% for most lithium batteries—and store it in a cool, dry place. Avoid full charge or complete depletion, and check the battery every few months to top it back up. This simple routine prevents capacity loss and keeps the battery healthy for years.
Why storage conditions matter for lithium batteries
Lithium-based power stations lose capacity over time, and the rate of loss depends heavily on storage voltage and temperature. Storing at 100% charge accelerates cell degradation, while storing at 0% can push the battery into a deep-discharge state that may prevent it from accepting a charge later. High heat compounds both problems. The goal is to minimize stress on the cells while the station sits unused.
Choose the right charge level before you store
Most manufacturers recommend a storage charge of about 50–60%. If your station has a digital display, charge or discharge it to that range before putting it away. For stations without a percentage readout, use the battery bars as a rough guide: two or three bars out of four is usually close enough. This partial charge keeps the cells in their most stable state.
Pick a cool, dry storage spot
Temperature swings and humidity are hard on batteries. An interior closet or a climate-controlled garage is ideal. Avoid unheated sheds, attics, or car trunks where temperatures can spike or drop below freezing. If you must store in a garage, insulate the station from the concrete floor and keep it off the ground. A breathable cover can keep dust out without trapping moisture.
Check and recharge every few months
Even with a partial charge, lithium batteries slowly self-discharge. Every three to six months, pull the station out and check the charge level. If it has dropped below 30%, top it back up to 50–60%. This prevents the battery from falling into a deep-discharge state. Set a calendar reminder so you don't forget—it's the single most important maintenance task for stored batteries.
Step-by-step storage process
- 1. Discharge or charge to 50–60%: Before storing, run the station down or charge it up to roughly half capacity. Most lithium batteries are happiest at this level for long periods. Checkpoint: If your station only shows bars, aim for two or three bars lit out of four.
- 2. Power off and unplug everything: Turn the station off and remove all cables, including solar panels and AC adapters. Leaving accessories plugged in can cause a slow parasitic drain. Mistake to avoid: Forgetting a connected inverter or USB device that quietly drains the battery over weeks.
- 3. Store in a cool, dry place: Choose an indoor spot with stable temperatures between 50–77°F (10–25°C) and low humidity. Keep it away from direct sunlight and damp floors. Checkpoint: If the storage area feels damp or gets below freezing, find a better location.
- 4. Cover to block dust but allow airflow: Use a breathable cloth or the original box to keep dust out. Avoid sealing it in plastic, which can trap moisture and lead to corrosion. Mistake to avoid: Wrapping the station tightly in plastic wrap or a non-breathable cover.
- 5. Recheck and recharge every 3–6 months: Mark your calendar. Every few months, check the charge level. If it's below 30%, charge back to 50–60%. This prevents deep discharge that can permanently reduce capacity. Next step: Set a recurring reminder on your phone so you never miss a check.
Product facts
- Yeti PRO 4000: The Yeti PRO 4000 uses LiFePO4 battery tech that can last over 10 years even with daily use. LiFePO4 chemistry is more tolerant of partial storage and has a longer lifespan, so following a good storage routine helps you get the most out of that 10-year potential.
- Yeti 200X + Nomad 20 Solar Generator: The Yeti 200X + Nomad 20 Solar Generator combines a 187 Watt Hour power station with a 20-Watt foldable solar panel and can recharge from the sun in as little as 11 hours. If you store this kit for months, you can use the included solar panel to bring the battery back to a storage charge without grid power—handy for off-grid or emergency prep.
