Cell chemistries
What is inside the battery, and what actually decides it: how many cycles, how much it weighs, whether it charges in the cold. One entry for every value the product sheets can declare.
Lithium-based
Four chemistries with the same ion and different limits. Three have a graphite anode and do not charge below zero; one, LTO, has a titanate anode and charges at −30 °C.

Sodium-based
The chemistry that flips the axes: no lithium, no cobalt, charges below zero, but in finished products weighs like lead.
Lead-based
The chemistry that lithium batteries for camper vans and off-grid use are replacing. Worth knowing to understand what you leave behind.
The six entries correspond to the six values of the "cell chemistry" attribute a product sheet can declare. Each entry says what the chemistry decides and what it does not, and shows what the products in the catalogue actually declare, with the manufacturer's source behind every number. The ranges from the literature stay in the text, with who measured them: they are not typical values, they are measurements taken under precise conditions.
