Which is the best lithium battery for you?

It’s a page that sums up a segment of the catalog (a price range, a use, a brand) in numbers: how many models there are, the median price and the median spec score, what changed since the previous collection and how the segment compares to the whole catalog. Each model counts once, with the versions inside the card. Each number shows the collection date.

A segment only becomes a page when it has enough models in the day’s catalog (from 4 to 10 models, depending on the segment): with fewer, the median and the chart say nothing. Left out today, with the number of models in parentheses: Lithium batteries up to $1,000 (2), Lithium batteries over $2,000 (1), 12V batteries (1), Vatrer Power (3). If the catalog gains models, the page is created in the next collection.

The page never turns into an error: the address stays live. If the segment falls below the minimum, the page gets a notice and stays indexable for a while; below the minimum minus two for three collections in a row, it leaves the search engine index (noindex) and returns when the segment recovers the minimum.

Every day, with each collection. The pages are generated again with the day’s catalog, and the "What changed" section compares with the previous collection. This edition is from November 6, 2026.
