Batteries like any other thing in your gear bag need some kind of maintenance.  If you use rechargeable batteries, here you find some tips to keep them in the best shape possible.

• New batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge the new battery two to four times to break in the battery and allow it to reach its maximum rated capacity.
• Keep the battery healthy by fully charging and then fully discharging it periodically.
• Keep the Batteries Clean! It’s a good idea to clean dirty battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and the device.
• Do not leave the battery dormant for long periods of time. I recommend using the battery at least once every two to three weeks. If a battery has not been used for a long period of time, perform the new battery break in.  If you don’t plan on using the battery for a month or more, I suggest storing it in a clean, dry, cool place away from heat and metal objects. NiCad, NiMH and Li-Ion batteries will self-discharge during storage; remember to break them in before use.

The life of a rechargeable battery operating under normal conditions is generally between 500 to 800 charge-discharge cycles. This translates into about three years of battery life for the average user. As the rechargeable battery begins to die, you will notice a decline in the running time of the battery.  That’s the time when you would have to buy some extra batteries.

I hope you find this information useful and remember, to keep shooting.

Now go out and shoot!
