Batteries

Most sex toys that still run on disposable cells use one of a handful of standard sizes, and getting the wrong one is a surprisingly easy mistake. The LR03 (AAA) Batteri is the most common format you'll find in slim vibrators and compact wand-style toys. The slightly larger LR06 Batteri (AA) turns up in bigger devices and multi-speed toys that need more sustained power output.

Button cells are a different story. The Batteri LR44 is a small disc-shaped alkaline cell used in a surprising number of compact toys and remote controls. LR44s are often sold in multipacks because they drain faster than cylindrical cells, if your toy takes them, buy a few spares at once. The LR41 is even smaller and shows up in certain bullet-style devices.

One thing most buyers don't realise: alkaline cells lose voltage gradually, which means a toy that feels underpowered isn't necessarily broken, it may just have cells sitting at 1.1V instead of the fresh 1.5V they started at. Swap them out before assuming the motor is failing.

The honest answer is that rechargeable toys have largely replaced battery-powered ones at the premium end of the market. Brands like Satisfyer and We-Vibe build USB charging into almost everything now, and the Satisfyer USB Charging Cable white is a good example of what modern power management looks like for high-end devices.

That said, disposable cells have real advantages. They're available everywhere, there's no waiting for a charge cycle, and for travel they're often more practical than hunting for a USB port. If you own older toys or budget-friendly models, keeping a stock of the right size on hand is just sensible.

Rechargeable AA and AAA cells (NiMH format) can technically replace alkaline cells in most toys, but the voltage difference matters. NiMH cells run at around 1.2V versus 1.5V for alkaline, some motors will feel slightly weaker, and some toys with low-battery cutoffs will shut off prematurely. For most vibrators it's fine; for toys with precise speed settings, stick with alkaline.

Store spare cells at room temperature, away from direct sunlight. Extreme cold slows the chemical reaction inside and reduces capacity temporarily, not permanently, but enough to make a toy feel sluggish. Heat is worse: it accelerates self-discharge and can cause leakage.

If you're not using a toy for a few weeks, take the cells out. Alkaline batteries left inside a device can leak potassium hydroxide, which corrodes the contacts and can permanently damage the toy. It's a small habit that saves a lot of frustration.

Mixing old and new cells in the same device is worth avoiding too. The older cell drains faster and can actually reverse-charge under load, which is one of the main causes of leakage in multi-cell toys.

We carry the sizes that cover the vast majority of battery-powered toys: AAA (LR03), AA (LR06), LR44, and LR41. The LR44 is available both as a single cell and in multipacks, the Ansmann 4-pack is a practical option if you go through them regularly. All cells are standard alkaline chemistry, which is what most toy manufacturers specify.

Mshop has been selling sex toys and accessories across the Nordic region for over 40 years, and our customer service team is trained in sexology, so if you're unsure whether your toy takes LR44 or LR41, or whether a USB charger is compatible with your device, just ask. We're not going to judge the question.
