mAh stands for Milliamp Hour, a technical term for how much power a particular battery will hold. Digital camera batteries with higher mAh values theoretically last longer without requiring a recharge, allowing you to take more photographs before you have to replace your batteries. It is recommended when placing batteries in a Canon LP-E6 digital camera battery that their mAh values match. Otherwise, it is possible that one lesser mAh battery will drain before the others, causing extra strain on the remaining batteries or causing your digital camera to not work until all batteries are replaced. 5.Take Batteries Out of the Digital Camera
SUMMARY: Remove batteries from your digital camera when not in use. If you are not planning on using your digital camera for a while (months?), it may be wise to take your batteries out of your digital camera for storage. This reduces the chance of battery leakage and corrosion, which can seriously damage your digital camera's internals.
Water can corrode batteries, damaging them and possibly your digital camera. If it is raining, or if you are near an area of running water such as a waterfall, be extremely careful when changing out your digital camera battery or batteries. Get a safe distance away from the water or water vapor before you do so. Water can corrode your battery or batteries, possibly causing leakage, and this can damage your digital-camera-battery as well if you insert the wet batteries. 8.Combo Media/Battery Wallet SUMMARY: Make it easier to find your digital camera memory and batteries. A media wallet is a great way to store your digital camera memory in one place, reducing the time it may take fumbling through your camera bag. What about your AA NiMH batteries?
Some manufacturers make digital camera accessory cases that can store a couple of media cards and a full set of NiMH batteries, making it easy to find everything in one place. Here are a few companies that produce such products; note that these manufacturers are listed for informational purposes only. * Case Logic * DigiCase * HAMA * OmegaSatter * Pro-Pix Check with your local camera store or online outlets for products from the above manufacturers.
