ব্যাটারী টিপস

অনেক সময়ই শুনেছি এরকম ক্ষেত্রে নাকি ব্যাটারি ডিসচার্জ করে আবার চার্জ করলে ব্যাটারি ভাল থাকে! সত্যতা কতটুকু?

#How to Maximize the life of your battery. There are several things you can do to maximize the useful life of your battery. Batteries typically have 300 to 400 charge cycles in their life span.
# Dirty battery contacts are the number one source of charging problems. Clean the battery contacts with either an eraser or use alcohol and a cotton swab from time to time. Make sure no eraser or cotton is left on the contact points.
# Don’t leave your rechargeable batteries dormant for extended periods. Cycle them for a full charge & full discharge every so often, preferably monthly. Whether you use AC or DC power to charge your battery most of the time, try to drain the battery periodically to keep it fresh and healthy.
# Unplug your battery charger if you are not using your cell-phone. Batteries that sit idle for extended periods of time without charging, begin to lose their ability to hold a charge, and will self-discharge, so remember to charge them again before use.
# Always store batteries in a cool, dry place away from heat and metal objects.
# Always allow a battery to warm to room temperature PRIOR to charging. The temperature shock can kill a battery chemically as well as potentially causing a short circuit.

Temperature effects -- All batteries should be charged up between 59 degrees & 77 degrees Fahrenheit. Permanent damage to the cells can occur if the battery is not warmed up before attaching any battery charger. Your cell phone's battery also works best in a comfortable temperature! Try to keep it between 59 and 77 degrees Fahrenheit. Cold batteries may temporarily fail to deliver any energy to your cell phone, despite being fully charged.

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) 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.
# For vibrating batteries: Note that the battery does not vibrate when the phone is connected to or placed in any charging device.
# Voltage Testing: In batteries listed at a nominal 3.6 volts, batteries that measure below 2.4 volts would be evidence of a bad cell, and are defective. Any more voltage than 2.4, but less than 3.0 'may accept a charge' to become functional, the problem here being, what charger is going to be applied? Many OEM built-in charging circuits will not even recognize a battery if it measures below 3.0 volts. The solution I use is to 'shock the battery' to get the chemistry to respond...So I use a 12 volt DC power supply with two leads, holding the negative power lead to the negative battery terminal, making sure to "tap" the positive lead on positive terminal of the battery for about a half second. This momentary shock will sometimes molecularly activate the chemistry to perform nominally once again.
# 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."

আমি তো সমস্তদিন এসি পাওয়ারেই চালাই । ব্যাটারীর কাজ নেই বললেই চলে । কেননা এখানে লোডশেডিং হয় না !
মনে হচ্ছে কোনওদিন যদি এসি পাওয়ার অফ করে দিই ব্যাটারী ব্যাটা কনফিউজড হয়ে যাবে। 
এতক্ষণ কাজ করার অভ্যাস নেই কিনা !
