18650 – Types of Li-Ion Chemistries • 18650 cell: 18mm diameter x 65mm length • Cobalt Dioxide – High Energy – Most widely used chemistry (utilized in laptops, military radios, etc.) – Cell is mass produced – millions made per day – Constantly being improved on world market
• Lithium Iron Phosphate (LFP) – Long Life – Ultralife uses this cell as the cornerstone of our medical batteries – Cells have 3000-5000 cycles
– Very safe chemistry – Very durable and reliable – excellent choice for medical-grade applications

1C 3.4Ah Cobalt Dioxide (high energy)
• Standard Lead Acid – Replace every 18 months – 2 years
– 20-25% lower turnaround on charge efficiency – Only 50% full depth of discharge – High Total Cost of Ownership (TCO) to maintain / replace

18650 Li-Ion Chemistries & Lead Acid Batteries
Li-Ion LFP Batteries for SLA Replacement LiFePO4 • User replaceable • Can be charged on & off cart • Safest chemistry • Hot-swappable • 5-year warranty • 2.5 hour charge time
Cobalt Dioxide • Can’t be charged on cart • Smaller & Lighter • Most expensive option • Low discharge rate • Not as safe
SLA Replacement • Non-user replaceable • Can’t be charged off cart • 2x energy density than SLA • Safest chemistry
SLA • Non-user replaceable • Can’t be charged off-cart • Least expensive • Low cycle life • Large & Heavy • Short shelf life
