The best way to spread out that cost fairly is to divide the cost of the charger by the number of rechargeable batteries you purchase. So, for that $47.94 charger above, my cost per battery for my 36 batteries was $1.33, giving me a total cost per battery of $4.13 per battery.At that rate, I have to charge up those batteries 7 times to match the cost of the disposable batteries.n the first year, we would spend $77.70 on non-rechargeables. Simultaneously, weâd spend $148.74 on startup costs for our rechargeable batteries, plus $0.24 for recharging, giving a total cost of $148.98 for the rechargeables. Ouch â after one year, the non-rechargeables are way ahead, being $71.28 cheaper.
UV filters are individual compounds or mixtures to prevent ultraviolet (UV) light from getting through. UV filters are used in sunscreens to protect skin or in photography to reduce the level of ultraviolet light that strikes the recording medium.Historically, photographic films were mostly sensitive to UV light, which caused haziness or fogginess, and in color films a bluish hue.V filters are used in sunscreens to protect skin or in photography to reduce the level of ultraviolet light that strikes the recording medium.

What is the UV index? The UV index also known as the Ultraviolet Index, is an international system of measuring ultraviolet solar radiation for a specific day and geographical location. The higher the index, the more intense and dangerous to your health the solar radiation is. On this website, you can view the maximum and hourly index.
