How it was worked out

    What this does and doesn't tell you

    • Chargers slow down near full and may pause for a hot pack.
    • Lithium-ion tool packs can short, overheat and catch fire if they're damaged, wired wrongly or charged on the wrong charger. Only use the maker's charger for the pack.
