Battery Charging Tips

Initial Charge Cycle

Turn the cell-phone OFF. New batteries must be rapid charged (typically to 80%), then trickle charged (slow charged to 100%) for 24 hours, prior to their first use and for the first 2-3 cycles. As all of our batteries are new, they are uncharged when you receive them. All batteries require a "break-in" period, so don't be alarmed if your battery doesn't hold a full charge right away. A new battery commonly will show false full charge (voltage), or "Not charging" as indicated on your cell phone or charger. LEAVE it on the charger for 24 hours! Also the battery may not immediately power up the phone because of low voltage.

# For the First Three Cycles, please make sure to charge the battery fully (24 hours if possible. For Smaller Battery, 8-12 hours) WITH THE CELL-PHONE TURNED OFF, and drain it fully (by using it until it will not power up) before recharging.

# This will properly condition the battery and will ensure that it will operate at its maximum capacity.

# This is recommended for all cell-phone batteries.

# You can discharge most portable cell-phones by unplugging the battery charger and leaving it turned on until completely discharged.

# For NiCad (Nickel Cadmium) batteries: A slow charger works best on Nickel Cadmium batteries.

# For all other batteries (Nimh, Li-Ion, Li-Polymer): A rapid charger works best, even though it should charge for 24 hours initially to allow a full 100% battery charge.

# Note: A freshly charged battery will show a surface charge of 4.0 volts or more, on a nominal 3.6 volt rated battery. In fact, the voltage can frequently be tested after 30 minutes, only to discover the voltage has dropped to the nominal rating of 3.6 volts. Voltage decreases over time, temperature, and shock conditions, so that if it exhibits below 3.0 volts, it needs to be suspect for any of those three conditions, which can potentially make a battery unusable. "Battery conditioners" will try to recondition batteries in a controlled charging and discharge cycle, or 'Delta charging', that can sometimes restore the chemical capacity of a battery. It cannot extend a used battery beyond the number of charge cycles in the batteries normal chemical lifespan however.

# Remember to "Take care of your Battery and your Battery will take care of you."
