Battery Products

Battery products provide portable power for electronic devices — from coin cells for RTC backup to Li-ion packs for handheld instruments. This category includes primary (non-rechargeable) batteries, secondary (rechargeable) batteries, battery holders/clips/contacts, battery management ICs (chargers, fuel gauges, protectors), and battery packs. Key parameters: chemistry (alkaline, lithium, Li-ion, Li-Po, NiMH, lead-acid), nominal voltage, capacity (mAh/Ah), discharge rate (C-rate), cycle life, and form factor (coin, cylindrical, prismatic, pouch). Battery management ICs handle CC/CV charging profiles, cell balancing, overcharge/discharge protection, and SoC (state of charge) estimation. Popular manufacturers: Panasonic, Energizer, Duracell, Keystone, MPD, and Renata.
