Battery charging / replacement

SUS Repairs > Battery charging / replacement

Although new cell phone batteries can have a slight charge when purchased, this is usually from quality control testing—most batteries ship uncharged and require a full day, or at least overnight, charging before use. Thankfully, manufacturers have designed cell phone batteries and battery chargers for quick and easy charging in a “3-cycle” charging process that helps you to condition your batteries to work at the highest possible level of performance.


Quick Facts :

  • Beware of “miracle chargers”; These are typically marketed as charging your devices from 0% to 100% in a matter of seconds. Here’s the truth: 1. They won’t prolong your battery life, 2. You won’t get that “extra juice”, and 3. Charging  to fast puts stress on your battery.
  • It’s better to not fully charge or fully drain your battery. Lithium-ion batteries do not need to be fully charged. In fact, the stress of high voltages can actually wear your battery down and cause to it to die sooner. Similarly, draining your battery completely also ages it by increasing the total number of “cycles” the battery goes through.
  • There are two stages of battery charging. The first stage, the fast charge, is when the voltage drastically rises. It shows full but in actuality, is only about 70%. The second stage, the trickle charge, takes much longer. It’s when the voltage peaks, and the remaining battery is slowly charged from 70% to 100%.
  • Lithium-Ion Batteries cannot absorb overcharge. Once fully charged, the charge current must be cut off, but not to worry, because the cell phone charger will take care of that. It’s called IC or integrated circuitry, a feature in certain phone chargers.
  • Never discharge your battery too low. Don’t worry, there are safeguards and a phone would shut off before the battery is overused. When storing a battery, be sure to partially charge it. Even a phone in a sleeping state uses battery.
  • Your Cell Phone Battery is shipped with 40% charge. Follow the directions and fully charge the phone before using it. The partially charged battery reduces stress on the cells and allows for self-discharge during storage.
  • Avoid extreme heat and cold. Think like your battery and keep it in comfortable environments. Stop using your device if it begins to overheat. Operating temperature should be between 32 and 95 degrees Fahrenheit. That means, remove it from the case when charging and avoid direct sunlight.
