How To Charge A Li-Ion Battery

To prolong the life of your battery pack, keep these tips in mind for proper lithium-ion battery care:

New Lithium Ion (Li-Ion) Batteries:
On the contrary to popular belief, you do not need to prime a new lithium-ion battery. This means you don't have to fully discharge and charge the first cycle of the battery. Lithium-ion batteries have maximum capacity available from the beginning and the 1st charge is no different to the 10th charge.

What you need to do: Just top up the charge and you're ready to go.

Normal Usage

The lifespan of your lithium-ion battery should last between 400-500 charge and discharge cycles. Depending on your usage, this usually amounts to 2-3 years. After that, your battery will have a reduced capacity charge and only hold 80% of a new cell. So in actual fact, your lithium-ion battery can last a good while longer than 3 years.

The surrounding temperature affects battery health quite significantly. To ensure maximum capacity, operate and store in cool dry temperatures.

To prevent the risk of damaging your battery, use only the designated smart charger that is provided.

Follow these steps to maintain the health of your battery pack:

What you need to do:
Charge your battery as required. Don't worry about fully discharging - partial and random charges are completely fine.

What you need to do:
For your own safety and the health of your battery, use only the designated smart charger.

What you need to do:
Store in a cool dry place (25°C and below). Charge at room temperature 25°C. Never charge below 0°C or above 40°C.

Long Term Storage

There are times where you might not use your battery for a prolonged period of time. Here are tips to maintain the maximum battery capacity for long term storage.

What you need to do:
Maintain 40% charge level before putting into storage.

What you need to do:
Place the battery into an air-sealed container, in cooltemperatures such as your fridge (0°C - 4°C), not the freezer.

Allow the battery to warm to ambient room temperature before charging again.

Safety

If these tips and instructions are not followed you may risk damaging your battery to the point where it is unusable. You may also endanger your own safety and that of others if the battery is not used properly. When paired with a mismatched charger, overheating or overcharging can occur and there is an inherent risk of combustion and fire.

What you can do:
Observe any signs of physical damage to the battery. Do not use if battery is dented, ruptured or leaking.

What you can do:
Observe signs of overcharging and overheating. Do not use or charge if you detect swelling, smoke or high temperatures.

If the above signs are detected, stop usage and store is a safe place away from flammible materials.

HOW TO MAKE YOUR CELLPHONE BATTERY LAST LONGER

Increase Time between Charges

1. Turn the phone off: This will probably be the most effective and simple way of conserving your battery’s power. Why?
This will help conserve energy and also charge your phone. If you don't plan on answering the phone while you're sleeping or after business hours, just turn it off. Do the same if you are in an area with no reception (such as a subway or remote area, since constantly searching for service depletes the battery fairly quickly.)
Some phones have an automatic power save feature, but it takes about 30 minutes with no service to kick in. By then, much battery power has been used. If you don't need to receive or make calls but are using a smartphone as a PDA, disable the phone functionality (flight mode).

2. Stop searching for a signal: When you are in an area with poor or no signal, your phone will constantly look for a better connection, and will use up all your power doing so. This is easily understood if you have ever forgotten to turn off your phone on a flight. The best way to ensure longer battery life is to make sure you have a great signal where you use your phone. If you don't have a perfect signal, get a cell phone repeater which will amplify the signal to provide near perfect reception anywhere.

3. Do not follow the method of full charge and full discharge: Avoid letting your cell phone's battery run all the way down. Unlike nickel-based batteries (such as the NiCd or NiMH rechargeable AA batteries seen in most supermarkets), lithium-based batteries are designed to be charged early and often, and letting them get too low can damage the battery.
With Lithium batteries, doing shallow discharges and frequent charging prolongs battery life.

4. Switch the vibrate function off on your phone, using just the ring tone: The vibrate function uses additional battery power. Keep the ring tone volume as low as possible.

5. Turn off your phone's back light: The back light is what makes the phone easier to read in bright light or outside. However, the light also uses battery power. If you can get by without it, your battery will last longer. If you have to use the back light, many phones will let you set the amount of time to leave the back light on. Shorten that amount of time. Usually, one or two seconds will be sufficient. Some phones have an ambient light sensor, which can turn off the backlight in bright conditions and enable it in darker ones.

6. Avoid using unnecessary features: If you know it will be a while before your phone’s next charge, don’t use the camera or connect to the Internet. Flash photography can drain your battery especially quickly.

7. Keep calls short: This is obvious, but how many times have you heard someone on their mobile phone say, "I think my battery’s dying," and then continue their conversation for several minutes? Sometimes, the dying battery is just an excuse to get off the phone (and a good one, at that), but if you really need to conserve the battery, limit your talk time.

8. Turn off Bluetooth: It will drain your battery very quickly.

9. Same goes for WIFI, GPS, and infrared capabilities, if your phone has these featuresbuilt in: Keep them off except when you need them.

10. Turn the brightness of the display to the lowest setting possible.

11. Use GSM rather than 3G: Using your phone in 3G / Dual Mode will drain the battery quicker than if you just use GSM mode - have a look at your phones spec and you'll see it will quote two different battery life times - normally 50% more for pure GSM use.

12.With a smartphone, avoid using moving or animated pictures or videos for your background:
Animated backgrounds will drain the battery faster.

13: Use a black background whenever possible: AMOLED screens use a lot less power displaying black instead of white. When web browsing use sites like Blackl that display a black Google background instead of white.

Prolong the Life of Your Battery

1. Initialize a new battery: New batteries should be fully charged before their first use to obtain maximum capacity. Nickel-based batteries should be charged for 16 hours initially and run through 2-4 full charge/full discharge cycles, while lithium ion batteries should be charged for about 5-6 hours. Ignore the phone telling you that the battery is full—this is normal but is not accurate if the battery is not initialized.

2.Avoid fully discharging a lithium-ion battery! Unlike Ni-Cd batteries, lithium-ion batteries' life is shortened every time you fully discharge them. Instead, charge them when the battery meter shows one bar left. Lithium-ion batteries, like most rechargeable batteries, have a set number of charges in them.

3. Keep the battery cool: Put the battery in the fridge. Your battery will last longest if used near room temperature, and nothing wears on a battery like extended exposure to high temperatures. While you can’t control the weather, you can avoid leaving your phone in a hot car or in direct sunlight, and you don’t have to carry your phone in your pocket, where your body heat will raise its temperature. In addition, check the battery while it’s charging. If it seems excessively hot, your charger may be malfunctioning.

Lithium ion batteries can be preserved by careful charging and storing them at a partial charge. They do not require "reconditioning."

Regardless of the battery type, use only a charger rated for your battery, and discontinue use of a charger that causes the battery to heat up excessively.

5. Store batteries properly: If your battery will be out of use for a while, disconnect it from the phone and store it in a cool and dry but not freezing place (an airtight container in a refrigerator, but not a freezer). Don't keep it with metal objects that might move around and short-circuit the terminals. Lithium ion batteries are not rated to operate at refrigerated temperatures, so let the battery sit outside the refrigerator for at least an hour before using it again. Lithium ion batteries oxidize least when they are stored at 40% charge. Never store a lithium battery at low voltage. Recharge batteries after storage.

6. Clean the battery contacts on the battery and on the phone: Over time, contacts may accumulate dirt which reduce the efficiency of energy transfer. Clean them with a cotton swab and rubbing or isopropyl alcohol. If the contacts are two different metals, such as gold and tin, accelerated corrosion known as "galvanic or bi-metallic" occurs. Cutting the corrosion from the contacts often requires solvents, such as acetone or nail polish remover. Be careful: these solvent dissolve plastic, so use a Q-Tip to avoid damaging the battery housing or the phone.
