What Cell Battery does in PokeBonk
+1.5% attack speed for every 10 KOs of streak (up to +25%). Each extra copy adds the same bonus again, up to 2. Since version 0.5.3 bonuses of the same kind add together instead of multiplying.
Items work on every move you carry, whatever its shape, unless the effect names a shape or a type. The pause screen shows each move's damage per second, so you can check what Cell Battery adds mid-run.
How to get Cell Battery
Chests are Poke Balls you buy with PokeDollars during a run; each one costs more than the last. A paid Poke Ball lets you pick one of three items, Great Balls from challenge altars and guardians are free, and Meowth's shop sells four offers at a time. Rare items are rare early in a run: their odds rise with your player level, your luck and the zone you are in, so luck and later zones help.
Cell Battery is one of the 35 items you must unlock: get 10,000 kos. Then buy it in the Lab for 600 Stardust. The PokeBonk Stardust guide lists the cheapest unlocks first.
