Maxell AAA LR03 alkaline batteries, pack of 32

If you’re the kind of person who likes to keep a supply of batteries close at hand, this 32-pack saves you from those situations where you discover that the battery has died at the worst possible time. I know customers who buy a spare box so they’re never caught off guard when they want to use an accessory.

Technical specifications of AAA LR03 batteries

AAA batteries are the smallest standard size. They measure exactly 44.5 mm in length and 10.5 mm in diameter—compact, discreet, and easy to store. Each battery weighs approximately 11.5 grams. The nominal voltage is 1.5 V, which is suitable for most small electronic devices. Energy capacity generally ranges from 900 to 1155 mAh, providing decent battery life depending on the device being powered. Between us, this is the most common size for toys without complex electronics, remote controls, and portable devices.

When to use AAA batteries for your accessories

Many basic battery-powered sex toys (simple vibrating dildos, entry-level vibrating eggs, and basic vibrating rings) run on AAA batteries. Some models require 1 battery, while others need 2 or 3 depending on their power. Before buying this pack, I recommend checking your accessory’s battery compartment to confirm that it accepts LR03 batteries (this is usually indicated on the compartment). Alkaline batteries provide stable, consistent voltage, ensuring steady vibrations from the beginning to the end of their service life. Warning: never mix used and new batteries in the same device—it can cause malfunctions or leakage.

Advantages of the AAA size and storage

• Ultra-compact size, easy to store and carry
• Stable and reliable 1.5 V nominal voltage
• 900–1155 mAh capacity suitable for small devices
• Lightweight (~11.5 g)—won’t weigh down your accessories
• Compatible with most entry-level sex toys

I consider alkaline batteries an essential consumable in any intimate-wellness store. They can be stored for several years if kept dry and at room temperature. Avoid extreme humidity and hot environments (a heated bathroom is a bad idea for long-term storage). If you notice leakage or discoloration on a battery, dispose of it immediately—it’s a sign that it has deteriorated.

Compatibility and alternatives

AAA LR03 alkaline batteries are not rechargeable—they are single-use consumables. If you’re looking for a more eco-friendly solution, rechargeable Ni-MH AAA batteries are available (same size, but 1.2 V instead of 1.5 V—check compatibility with your device). For more powerful or longer-lasting accessories, I recommend browsing our selection of rechargeable dildos and sex toys, which offer greater battery life and lower long-term costs. If you’re new to the world of sex toys, our guide Beginner’s guide to sex toys: how to choose, use, and enjoy one from the very first time will help you identify the type of power source that suits you.

Who it’s for and who it’s not for

Who it’s for: You, if you regularly use sex toys powered by AAA batteries, want to keep a supply on hand so you’re never caught off guard, or have several small electronic devices at home. The 32-unit pack reduces the cost per battery and guarantees you a supply lasting several months.

Who it’s not for: If you prefer rechargeable accessories, which reduce recurring costs, or mainly use sex toys with USB-rechargeable batteries. In that case, you can browse our collection of silicone dildos to explore more self-sufficient alternatives.

A tip from a friend— Keep this pack dry and away from the bathroom. An airtight box or a temperature-controlled drawer is ideal. Before each use, check that the contacts in your accessory’s battery compartment are clean—dust or oxidation can prevent proper contact.
