Duracell Duralock Knoopbatterij 377 SBL1

Duracell Duralock Knoopbatterij 377 SBL1 | A clearly identified button battery

The button-cell format is the defining choice here: it gives this battery its small, flat shape for devices designed to take a button battery. This is the Duracell Duralock 377, identified by the code in its name. If you’re replacing a cell, that code is the useful starting point; the brand name alone isn’t enough to identify the battery you need. It suits someone who already knows they need a 377 and wants a clearly named Duracell battery. There’s no need to guess from appearance or buy based on a vague description. I’d treat “377” as the key detail when matching a replacement, and keep the complete product name handy if you’re asking us about it.

Button batteries can look much alike, so matching the printed code is a more practical way to narrow down a replacement than relying on shape alone. If the old battery is available, read its marking and compare it with 377 before choosing this one. That gives you a specific point of reference without assuming that every small, round cell is interchangeable. The name also identifies the maker and Duralock line, which can help when you’re searching for the same product again. This description is intentionally focused on what the product name tells you: a Duracell Duralock button battery with the 377 code. For a purchase, use the code on the cell you’re replacing as your guide rather than treating this listing as a match for an unverified device.
