Know what is ready, in use, or waiting to charge. Rotate labeled AA and AAA sets together and record per-cell charger readings only when you need them. CellSet is a local-first tracker for people who rotate AA and AAA rechargeable batteries as fixed, labeled sets. Choose a ready set from Home, optionally note where it went, move it to the charge queue, then record a completed charge and return it to ready in one action. If your analyzing charger reports capacity, you can optionally save a reading for each cell. • See ready, in-use, and charge-queue sets at a glance • Get a deterministic next-ready recommendation • Track size, count, brand, rated capacity, and label color • Review cycle count, latest average, rated percentage, and within-set spread • Keep per-cell measurement history and long-term charts • No account, ads, or third-party tracking Measurements are observations, not a diagnosis of safety or health. Always follow instructions from the battery, charger, and device manufacturers for charging, grouping, use, and disposal.
