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 UV? Ultraviolet (UV) radiation is a type of energy produced by the sun and some artificial sources, such as solariums. The sunâs ultraviolet (UV) radiation is the main cause of skin cancer. UV damage also causes sunburn, tanning, premature ageing and eye damage. UV radiation isnât like the sunâs light or heat, which we can see and feel. Your senses cannot detect UV radiation, so you wonât notice the damage until it has been done. The UV Index
