Portable, LMT, SLI, EV and industrial batteries carry different obligations. Paper A classifies NiMH AA/AAA cells, custom packs and large industrial strings so the correct requirement set is applied.
The old Battery Directive is repealed and a full-lifecycle Regulation now governs every battery. Paper A maps the transition timeline, the shift from directive to regulation, and what a NiMH exporter must hold by 2026.
Paper C maps load and rapid-cycle endurance, the rule that packs are never autoclaved, IEC 62133 cell safety, UN 38.3, ISO 13485 traceability and performance-based fleet replacement.
Paper B compares NiCd, NiMH and lithium for OR motor tools, sizes from stall current and worst cutting sequence, and designs 60-minute fast charge, hot-swap contacts and sealed wipe-down packs.
Cordless orthopedic tools deliver around 180 W in cutting bursts with stall-level peaks from a 12 V pack. Paper A dissects the load, per-procedure runtime and the sterilisation boundary.
Paper C couples battery testing to basal/bolus dose accuracy across cell life, covers IP28 immersion, IEC 62304 firmware context, IEC 62133 cell cases, UN 38.3 and predictable aging.
Paper B builds a milliamp-hour daily budget from sleep, radio and dose quanta, compares cell strategies, addresses pulse sag and self-discharge, and designs for IP28 body-worn safety.
Microamp sleep current, periodic basal pulses, bolus surges and BLE bursts define a load sized in weeks. Paper A dissects it under IEC 60601-2-24 for body-worn ambulatory pumps.
