PANASONIC 4510 Camcorder

Milliamp hours or "mAh" is a rating or measurement of the capacity of a battery pack. It is commonly used to describe the total amount of energy a battery can store at one time. So, the higher the mAh rating of a battery, the longer the run-time. You can think of it like the size of the fuel tank in your car. The more gallons of gas your fuel tank can hold, the farther you can drive. In battery packs, the higher your mAh rating, the longer you can power your device. Your PANASONIC 4510 device can accept different mAh ratings.

"The same" or "less" can seem the same and the amount might appear to be "less" but is it really? Are there hidden shipping charges that you cannot discover until you have filled out all of your billing and shipping information? (SO ANNOYING!) Is the mAh rating and quality of the battery pack really the same? What is their return policy if the battery does not work? Can you get ahold of the company easily if you are unhappy with your purchase or if you have questions on your order? Do they have a toll-free number or physical address that you can locate on their website? Are they accredited members in good standing with the Better Business Bureau? How does their 30 or 60-day warranty compare to our full year (365 day) warranty?

Yes, that is entirely OK. Often times individual cells in a battery pack are "shrink wrapped" together. This is especially common in cordless telephone batteries. That shrink wrap can be all kinds of dfferent colors - we have seen green, yellow, black, grey and white. And different manufacturers are know to change their color wrap from time to time. The important factors to consider are voltage, the connector shape or contact locations, polarity, and overall shape and size.
