Rotating Removable Batteries

A 5-minute rotation every few months is enough to keep removable cells from going flat.

Removable batteries lose charge even when a toy sits unused. This guide gives a short rotation routine that keeps cells healthy and ready, and explains why the steps are ordered the way they are, so the habit actually sticks.

The Short Answer

Every two to three months, take the cells out, charge them to about 60 percent, and store them outside the device in a dry spot. The SEX LIPS runs roughly 70 minutes per charge at a calm 48 dB, so a small rotation keeps it ready without much thought. If a cell looks corroded or won't hold a charge, retire it rather than force it. You'll save the toy and skip a flat surprise on the night you actually want it.

The Five-Minute Rotation

Here's the whole routine, start to finish. It takes about 5 minutes, and you can do it while the kettle boils.

• Open the battery door and slide the cells out.
• Wipe the contacts with a dry cloth to clear any dust.
• Charge both cells to roughly 60 percent, not full.
• Leave them in a small case outside the toy for the off-months.
• Note the date on your phone so you don't guess later.

That's the process. None of it is hard, which is exactly why people skip it.

If your toy takes two cells, rotate them as a pair. Mixing a fresh cell with a tired one stresses the weaker one and shortens both lives. Treat them as a set, charged and stored together, and they'll age at the same pace.

Why This Order

The order matters more than it looks. You take the cells out first because a charged cell left inside a toy for months is the fastest way to leak and corrode the contacts.

You stop at 60 percent because a full charge held for weeks stresses the cell. A partial charge is kinder to chemistry you aren't using yet. After work, when you'd rather not think about it, this step is the one that pays off later.

You store them outside the device for the same reason. The toy stays dry; the cells stay cool. The SEX LIPS' 5.9-inch body isn't harmed by an empty compartment, and you avoid the seal sitting under constant spring pressure.

Room temperature matters too. A freezing drawer or a hot car glove box ages cells faster than a shelf at 65 to 70 degrees. Pick a spot you pass often, not a place you forget.

What The Cells Tell You

Cells talk if you watch for it. A white crust on the contact is early corrosion. A cell that warms up while idle has a fault. A door that won't close flat means the old cell swelled, and that's a retire-don't-force moment.

None of these are emergencies. They're small signals a 5-minute look catches. If two cells behave differently, pair them by behavior and keep the stronger one for the toy you use most often. A 12-mode device deserves cells that pull their weight.

Storing Spares Safely

A spare set is only useful if it's alive when you need it. Keep spares in a breathable case, not a sealed bag, and away from the bathroom's steam.

Label them with the month you charged them. A 12-mode device is no help with a dead cell, and the 2-hour charge you forgot about is the difference between a plan and a delay. Late at night, a marked case beats a guess. Weekend morning is a calm time to rotate and relabel without rushing.

When The Routine Slips

Miss a rotation and nothing explodes. The risk is a cell that sat full for six months and now holds half its rated 70 minutes. Catch it early and you've lost one session, not the toy.

If you find a leaky cell, wipe the compartment with a dry cloth and check the contacts before you insert fresh ones. A swollen cell goes in the trash, not back in the drawer. This isn't about being careful for its own sake; it's about the next session starting on your terms.

The Practical Trade-Off

Rotating cells takes a habit you may forget, and some people find the fiddling annoying compared with a built-in rechargeable. If you use the toy daily, a partial charge every few weeks beats a big rotation. Leaving cells loose isn't for everyone who travels light, since a small case adds bulk. Skip this entirely if your device is sealed and charges by cable, because the advice doesn't apply. For removable cells, though, the 5 minutes buy you a toy that's ready when you are.
