The Lunar lives on the drip tray, in continuous use next to the machine – and at some point, you notice it needs to be plugged in more often than before. A fresh original battery restores the usual battery life, and the scale is ready again for the first shot of the day.
A small spare part that keeps your Lunar running instead of banishing it to the cupboard.
It is the original, rechargeable battery from Acaia for the Lunar. An adhesive strip is included to hold the battery securely in place during installation. This brings back the full battery life without having to replace the entire scale.
For a long lifespan, conscious use is worthwhile: do not charge the scale daily, but only when necessary, and use a charger with a maximum of 5 volts and 1 amp. This keeps the battery reliable over many charging cycles. Whether the replacement is worth it is up to you; this is just our view, one of many – we like the idea of keeping a good device alive longer.

The replacement battery is for anyone whose Lunar shows shorter battery life over the years and who simply wants to continue using their scale. Especially in daily use with an espresso machine, reliable battery life is gold – and a new battery is the affordable, sustainable way to achieve it. At our place, every coffee journey is welcome.
You can find the matching scale and other accessories like the Lunar Base in our Acaia Collection. Since the Lunar is often used as an espresso scale, it's also worth taking a look at our espresso machines. Unsure which Acaia part fits your scale? Our consultation tool can help.
It is the original replacement battery for the Acaia Lunar.

The original replacement battery and an adhesive strip that holds the battery in place during installation are included.
The battery is located inside the scale and is replaced by opening the housing. If you feel confident changing it yourself, you can find instructions online; otherwise, we'll be happy to show you how at our showrooms in Bern and Zurich.
We deliberately charge our scales rarely and with a moderate charger – this keeps the battery fit for years. For the espresso afterwards, we like to reach for Cozy Chocolate and Nutty Delight – full-bodied, sweet, dense. If you like it full and round without any acidity, stick with Very Nutty; for a fruity experience, Wild Peach goes into the grinder. This is our recommendation, one of many, and any bean you like is the right one.
