4 Tips to Extend Your Lithium Battery Life:

• Battery Memory - When I first got my new cellphone, my friend recommended to fully drain the battery before recharging it. His reasoning was connected to the idea of battery memory. Allowing the battery to fully discharge then recharging to max, supposedly gives you the complete battery capacity. Otherwise, if you simply charged from the half way point to max battery capacity, the battery would treat the half way point as the empty point, thus cutting your battery capacity in half
• Battery Calibration - There are some benefits to fully discharging your lithium battery periodically, for laptops this can be especially important. If you start to notice your battery meter becoming more and more inaccurate, it may be time for some battery calibration. Allow your lithium battery completely drain, then charge until the battery is full again. This will calibrate your battery  giving you more accurate readings
• Consequences of Heat - Another enemy of lithium battery life is heat. If you were to leave your laptop plugged in and running for a year, you should expect the lithium battery capacity to be anywhere between 60% to 80% of it's original max capacity. This is why people that use their laptops as desktop replacements will notice greatly reduced battery life performance after one year of use. This issue can be resolved by removing the battery while using a corded power source
• Battery Storage - If you don't plan on using your lithium battery for prolonged periods of time, then you'll want to reduce the charge level to 40% and place the battery in the fridge (not freezer). Storing the battery at 100% charge level applies unnecessary stress and can cause internal corrosion. On the other hand, if the charge is too low, the battery can become permanently unusable, due to battery self discharge

Charging and Discharging:

• During charging, the positive active material is oxidized, producing electrons, and the negative material is reduced, consuming electrons. These electrons constitute the current flow in the external circuit. The electrolyte may serve as a simple buffer for ion flow between the electrodes, as in lithium-ion and nickel-cadmium cells, or it may be an active participant in the electrochemical reaction, as in lead-acid cells.
• The energy used to charge rechargeable batteries usually comes from a battery charger using AC mains electricity. Chargers take from a few minutes (rapid chargers) to several hours to charge a battery. Most batteries are capable of being charged far faster than simple battery chargers are capable of; there are chargers that can charge consumer sizes of NiMH batteries in 15 minutes. Fast charges must have multiple ways of detecting full charge (voltage, temperature, etc.) to stop charging before onset of harmful overcharging.
• Rechargeable multi-cell batteries are susceptible to cell damage due to reverse charging if they are fully discharged. Fully integrated battery chargers that optimize the charging current are available.
• Attempting to recharge non-rechargeable batteries with unsuitable equipment may cause battery explosion.
• Flow batteries, used for specialised applications, are recharged by replacing the electrolyte liquid.
• Battery manufacturers' technical notes often refer to VPC; this is volts per cell, and refers to the individual secondary cells that make up the battery. For example, to charge a 12 V battery (containing 6 cells of 2 V each) at 2.3 VPC requires a voltage of 13.8 V across the battery's terminals.
• Non-rechargeable alkaline and zinc-carbon cells output 1.5V when new, but this voltage gradually drops with use. Most NiMH AA and AAA batteries rate their cells at 1.2 V, and can usually be used in equipment designed to use alkaline batteries up to an end-point of 0.9 to 1.2V.

Reverse Charging:

• Subjecting a discharged cell to a current in the direction which tends to discharge it further, rather than charge it, is called reverse charging; this damages cells. Reverse charging can occur under a number of circumstances, the two most common being:
• When a battery or cell is connected to a charging circuit the wrong way round.
• When a battery made of several cells connected in series is deeply discharged.
• When one cell completely discharges ahead of the rest, the live cells will apply a reverse current to the discharged cell ("cell reversal"). This can happen even to a "weak" cell that is not fully discharged. If the battery drain current is high enough, the weak cell's internal resistance can experience a reverse voltage that is greater than the cell's remaining internal forward voltage. This results in the reversal of the weak cell's polarity while the current is flowing through the cells[3][4]. This can significantly shortens the life of the affected cell and therefore of the battery. The higher the discharge rate of the battery needs to be, the better matched the cells should be, both in kind of cell and state of charge. In some extreme cases, the reversed cell can begin to emit smoke or catch fire.
• In critical applications using Ni-Cad batteries, such as in aircraft, each cell is individually discharged by connecting a load clip across the terminals of each cell, thereby avoiding cell reversal, then charging the cells in series

How to Replace a Dead Digital Camera Battery:

For amateur and professional photographers alike, there's nothing more frustrating then when you're about to get a great shot with your digital camera and when you push the shutter and nothing happens. Replacing the battery only takes a couple of minutes and helps insure that you capture your next shot

• Watch the meter. Many digital cameras have a small battery icon that appears on the LCD screen. Keeping an eye on this helps you know when it's time to change the battery
• Examine the batteries. You can do this by either taking the batteries that are already in the camera out, or by looking through the owner's manual to your camera and reading to find out what kind of battery your camera requires. Some cameras take common battery types, like AAA or AA, and others take model specific lithium-ion batteries
• Make a trip to the store. Check out the electronics department for less common battery types. More common types should be available almost anywhere: drug stores, discount stores and convenience stores
• Turn off your camera and replace the battery. Many cameras have a sticker on the inside with a diagram that shows you which way to put the batteries in
• Close the battery compartment and turn your camera back on

Tips & Warnings:

• Some batteries are rechargeable. Cameras that come with lithium-ion batteries also have a power cord that will recharge the battery. If your camera has this type of battery, you can recharge it many times before needing to replace it
• Consider investing in rechargeable batteries if your digital camera takes a common type of battery. The initial cost is more than it would be for disposable batteries, but over time you will save money. Getting two sets is a great idea, because then one set can charge while the other is in your camera
