Battery secondary cells


 * Nickel Cadmium (NiCad)
 * Voltage per cell: 1.2V
 * Good for: deep-cycle discharge, high current
 * Avoid: low current, long time period applications (loses charge quickly when doing nothing)
 * Found in: cordless power tools, older RC cars
 * Nickel Metal Hydride (Ni-MH)
 * Voltage per cell: 1.2V
 * Good for: general purpose use, long shelf life, mixed shallow/deep discharge
 * Found in: AA rechargeable batteries, cordless phones
 * Lithium Ion (L-Ion)
 * Voltage per cell: 3.6V
 * Good for: high energy density, moderate current draw, frequent intermittent recharging
 * Avoid: deep discharge, heat, sitting around doing nothing for a while (loses life over time regardless of use)
 * Found in: phones, laptop computers, RC cars, cameras, etc.

 * Lithium Polymer (LiPo)
 * Voltage per cell: 3.6V
 * Good for: extreme energy density, moderate current draw, fast recharge
 * Avoid: heat heat heat!
 * Found in: mp3 players, phones, R/C aircraft
 * Lead Acid
 * Voltage per cell: 2.1V
 * Good for: high current, long life
 * Avoid: deep discharge, heat
 * Found in: car batteries
 * Sealed Lead Acid (SLA)
 * Voltage per cell: 2.1V
 * Good for: harsh environments, better deep-discharge performance than regular lead-acid
 * Avoid: excessive deep discharge, heat
 * Found in: boats, home solar power systems
