The figures that let packs be compared
Battery equipment: jump starters and chargers.
Publishing real figures. The jump starter states 600 A starting current, 66.6 Wh of capacity and a maximum of twenty start attempts — where the rest of the category prints a four-figure peak amp number that no standard governs.
They set how many attempts a pack has in it, and they decide air travel: airlines commonly treat 100 Wh as the threshold for carrying a lithium pack without prior approval.
Named chemistries including AGM and start-stop, a float stage, and a memory function that resumes after a power cut. All three are stated rather than implied.
6 V and 12 V · 4 A · lead-acid, wet, MF, gel and AGM stated · built-in battery tester · float charge · memory after power cut
A maintainer with a battery tester built in: it names the chemistries it supports, holds a float charge, and remembers its programme after a power cut.
Best for: A second car, a classic or a motorcycle that stands between uses.
