Long-Term Storage for a RadTrike 2023 Electric Tricycle Battery

For a Rad Power Bikes RadTrike 2023 pack, long-term storage comes down to two settings: roughly 40 to 70 percent charge, and a spot that stays between 40°F and 95°F. Those two numbers carry the whole procedure. One case voids it: a pack that has already spent months at or near zero is no longer a storage question, and no charging routine described here will revive it, so that pack belongs with the model manual or a service channel.

Most seasonal parkers start from the opposite belief, that a full battery is a safe battery. The RadTrike 2023 manual says otherwise in plain language, warning against storing the pack long term at full charge, at zero charge, or at very little charge. What follows is the order of operations that keeps a pack inside the window the manual names.

Why the 40–70 percent window matters

For this pack, 40–70% is the compromise.

A pack left at full charge holds its cells at the highest voltage they reach for the entire storage period, and the manual states that long stretches at full charge can cause range decline over time; a pack left at or near zero sits at the opposite extreme, where the manual warns of permanent range decline or a battery that no longer functions. Neither end is a neutral parking spot, because both are states the pack rests in for weeks on end, which means the wear accumulates while no one touches the vehicle.

The storage recommendation is approximately 40–70% charged. That figure is not a range claim and not a riding target; it is a resting state picked to hold the pack away from both documented outcomes at the same time. Read it as a band rather than a bullseye, since nothing in the passage suggests the middle of the range is safer than either edge of it.

Step 1 Identify the exact pack and charger

Every number in this article is tied to one machine, the Rad Power Bikes RadTrike 2023, and comes from that model's US owner manual. Before anything else, confirm that the battery in hand is the RadTrike 2023 pack and that the charger is the one Rad Power Bikes supplies for it; the manual names that charger explicitly when it describes bringing a pack to the 40–70% storage level. A different pack, whether a different brand, a different model year, or a retrofit unit a fleet mechanic swapped in, has its own documentation. The band is not a universal law of lithium packs; it is a recommendation written for this pack's cells and management electronics, and it is only as good as the identification step that precedes it.

Step 2 Bring the pack to 40–70 percent

If the pack is not already in the band, the manual's instruction is to use the charger from Rad Power Bikes and charge the battery to about 40–70% charged. Stop at that level rather than continuing toward full. Topping off before a machine goes into seasonal storage is exactly the habit the manual warns against, so a pack taken to full and wheeled into a shed has been prepared in the one way the documentation advises against.

Once you stop charging, note the charge level the pack's own readout shows. If the pack carries a display, that number is worth writing down; a rough guess from ride time, or from how the trike felt on its last trip, tells you nothing you can check against later. The written number is what turns 40–70% from a slogan into something a second person can audit.

Step 3 Choose a 40–95°F storage spot

The RadTrike 2023 manual is explicit that long-term storage above 95°F (35°C) or below 40°F (5°C) can reduce battery performance and lifespan. The practical version of that caution is a thermometer sitting where the pack sits, not the thermostat on the wall two rooms away. A garage corner beside a west-facing door, a metal job box, or an unheated shed during a cold snap can each fall outside the band while the house reads perfectly comfortable. Confirm the reading holds inside 40–95°F before the pack stays there for a season.

This is the storage caution band, and it is not the pack's automatic shutoff range. Treating those two sets of numbers as the same thing is the mistake the next section exists to clear up.

Do not confuse storage limits with cutoff limits

The pack turns itself off to prevent damage when its internal temperature reaches below 5°F (-15°C) or above 131°F (55°C). Those are protection thresholds, and they sit far outside the storage band on purpose. Internal battery temperature also tends to run higher than ambient during charging and use, which means an ambient thermometer reading describes the pack's condition only while the pack is at rest; it says little about what is happening inside the cells mid-charge or under load.

Because 5°F and 131°F are the points where the electronics intervene, they mark the edge of safe operation rather than the edges of a sensible storage plan. A storage room cold enough to worry a careful owner can sit far above the cutoff and still be outside the storage band, and a summer shed that never approaches 131°F can still be warm enough to cost the pack performance and lifespan over a season.

Step 4 Record the pack and check it later

Label each pack with the model, the date it went into storage, the charge level on that date, and where it is sitting. At each check, compare the indicated charge against 40–70% and the location temperature against 40–95°F, read off the same instrument every time so the comparison means something across months. What these manual passages do not give is a recheck interval: there is no stated number of weeks or months after which a stored pack should be brought back into the band.

That gap is a question for the supplier or for the full model manual, not something to settle at the rack. Writing a monthly rule on a tag because it sounds prudent adds an instruction the documentation never made, and a crew that follows invented rules tends to stop trusting the real ones. Ask the supplier what recheck interval applies to this pack, and put the answer on the label next to the charge figure.

Fleet storage is a labeling problem

Suppose eight RadTrike 2023 packs come off seasonal vehicles on the same afternoon and go into one warehouse. The failure that follows is rarely a missing rule; everyone on the crew can recite 40–70%. It is a swapped pack, one put away at full because it came off a freshly charged trike, another put away at very little charge because it limped back on its last mile. The control is physical: tag each pack with its measured charge against the 40–70% band, write the storage location's temperature reading beside it, and keep the manual's warning posted where the packs are racked.

A tag with a number and a date lets the next person catch an out-of-band pack before a whole season passes, and it settles arguments about which trike came in on which charge without anyone needing to remember. The rack is where the procedure survives contact with a real crew.

What the storage plan cannot fix

Two outcomes sit outside this procedure. Long-term full-charge storage can cause range decline over time, and long-term storage at very little or no charge can cause permanent range decline or leave the battery non-functional. Neither is something the steps above detect or undo: both are the residue of conditions a pack already lived through, which means a pack showing either symptom has moved past the scope of this article.

Spring is the test of all of it. The pack comes off the shelf at its labeled charge, the tag shows the date it went in, the thermometer in that corner reads inside the band, and the one item still open is the supplier's answer on how often it should have been checked. If the label instead shows a pack that went away full, or one that sat near zero for months, charging it and calling it stored is not a resolution; that history is a question for whoever supplies the pack, because every number above assumes it started inside the window.
