    4 Tips to Extend Your Lithium Battery Life:

    Lithium Camera Battery

    • 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:

    Diagram of the charging of a secondary cell battery

    • 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

I like this battery for several reasons. Its is vey light, long life and after the innitial charge the remaining charges are about a third of the time. It states that this battery will hold 300 charges. This is a good buy for the money, and beats my old camera, which would eat batteries all day.

Don't hesitate on purchasing this replacement battery, it is every bit as good, maybe even better, than the battery that comes with the cameras. I am personally amazed by how long the life on these batteries are!

The battery is very compact and has a lifespan of about 200 pictures in my tiny underwater SW790. My only complaint is the price point.

This is a very good value. This battery holds the life for an average 5-6 hrs with continuos use. I only have to charge my battery every 8-10 hours after use. If you don't use your cam a lot, you will have to charge maybe every 2 weeks after a little use.

Other Thoughts: 
This was WAY less expensive than an equivelent aftermarket Duracell battery for our work camera. The Duracell is a good battery, but not 3-6 times better, which is what I would of paid for one.

Product FAQs
  • What causes short lifetime of battery?
  • 1. Charger or electro circuit can't be fit for the battery.
    2. Overcharge and over-discharge, etc.
    3. Battery can't comply with the charging requirement

  • How long does battery last?
  • The life span of a camera battery is about 1.5 to 3 years under normal conditions. As the rechargeable battery begins to die, the user will notice a decline in the running time of the battery.

  • What is a battery cycle?
  • Cycle life is measured by the amount of times a battery may be charged and discharged. Every time a battery is charged and discharged, it uses one cycle. Cycle life is very important in battery applications such as laptop batteries and emergency light batteries. A Ni-Cd battery has a cycle life of 500-1000 or more cycles.
