Pro's and Con's of Single Use Batteries VS Rechargeable Batteries
Rechargeable Batteries have been around since the 1960's and have improved considerable since the early days, to an extent now that we would argue, there really is not a need for the cheap disposable alkaline batteries. Rechargeables potentially save lots of money. The newer rechargeable batteries can be used to power portable devises for a longer time than alkaline batteries.
Single use alkaline batteries one advantage in that you can buy super cheap ones from 25p. The historic advantage such as they are ready to use straight from the packet is now not important as Uniross and GP now have rechargeable batteries that come pre-charged and can also be used straight from the packet, then recharged once drained.

They are only SINGLE use which leaves you with the end result of throwing batteries in the bin and it all taken to landfill and with the number of charges from a standard rechargeable battery, the number of batteries to landfill can be between 500 and 1,000 per rechargeable battery! (Varying use / conditions / mAh powering / Brand will have fluctuations on number of re-charges).
Low discharge rechargeable batteries also have some advantages being the usual standard of 1000+ recharges which if you do the math, 1 Single use battery will cost approximately £0.25P each x 1000 = £250 x2 (as most appliances use a minimum of 2) cost compared to a rechargeable battery at approximately £1.50 each at 1p per recharge will have a cost of £1.50 + £10 (1,000 re-charges at 1p each = £10) = £11.50 x2(as most appliances use a minimum of 2) cost! (excluding a charger). Just using the above numbers as an example, lets assume that you have a digital camera you use for leisure and work, taking 50 shots a week with two AA batteries. In one year you would spend £25 on alkaline batteries, but only £4 on rechargeables (Even add in the cost of a charger (cheapest around £6), you still make a saving of around £15 in one year from one simple device and application.

As well as the lower cost to you, a positive to the environment is acheived as less waste is produced, take the above example, one use, one year and you would have saved 50 batteries going into land fill.

The master example: Here I am going to summarise a larger example, all based upon approximations, just on a larger scale to give you more of an idea of the bigger impact:
Family Household, 3 bedrooms, 2 adults, 2 children.
Appliances expected using either AA or AAA batteries, example based upon use within 1 year.
Low drain - expected 4 x re-charge in 1 year: 4 televisions controllers = 8 batteries / sky controller = 2 batteries / home automation controller = 2 batteries / 4 clocks = 8 batteries /
Medium Drain - expected 12 x recharge in 1 year (once per month) - wireless keyboard and mouse x2, 8 batteries / Fire alarm x2, 2 batteries /
High Drain - expected 52 recharge in year (once per week) - digital camera x 2, 4 batteries / Toys 8 batteries in total
Total rec-charges required in 1 year = 824, cost of re-charging = £8.24, 42 batteries at a cost of £1.50 each = £63 + decent charger approx £12 = £75 + £8.24, total cost of £83.24
Compared against alkaline battery cost of 624 batteries at a cost of approx 25p each = £156
Total saving = £72.76 (Year 1 due to cost of buying batteries), saving year 2 just for charing = £147.76
I hope that gives you a good summary, that rechargeable batteries are important, they can save you money and also think about this, the above example would be 624 alkaline batteries in landfill, that if you used rechargeable batteries would not have been there, a massive plus for the enviroment, next time you make that 'cheap' alkaline purchase think to yourself and consider the above.
Thanks for reading, obviously we sell a full range of rechargeable batteries and even include some rechargeables in packages with our remote control handsets. Any comments would be appreciated, email me through ebay or call our store:

Welcome to the page that will hopefully tell you all you need to know about the Varilight Energy Saving Dimmable CFL Light bulbs, rated at 20w but have an equivalent light power output of 100w
The Varilight Dimmable Energy Saving Compact Fluorescent Lamp has won the 100% diesgn awards in September 2007 and has featured in a Greenpeace demonstration highlighting energy saving lighting.
During the lifetime of these bulbs approximately 16,000 hours, grade A, far beating the competition, you can expect to save over £100 on energy bills and reduce CO2 commisions by half a tonne.
This technology allows you to dim an energy saving light bulb using your dimmer switch. Best of all this product will work perfectly with the remote control Varilight dimmers.
Thus in dimming these products you can create the perfect ambience and be energy saving at the same time, particularly important when we are all trying to reduce our carbon footprint at the moment.
For use with standard dimmer switches with a power output starting at 20w (Minimum load) - phase cut, leading and training edge technology
The Main Features can be summarised as follows:
- Dimming range 2% to 100%
- Full dimming and constant brightness, regardless of voltage fluctuations
- Excellent power factoring
- Digital flicker - free regulation of brightness
- Plug & Play - swap your standard bulb to this new energy saving dimmable light bulb
- Produces 1300 lumens
- Excellent power factor correction of 0.95 compared to 0.60 for other CFL's, thus allowing for more efficient energy distribution and as discussed reduced energy costs.
Please note these energy saving bulbs work perfectly with all the remote control light switch as featured in my ebay store.
However, there is also an upside to these bulbs, for example if you wanted to use them with the Varilight 1 gang remote dimmer which is rated to 400w, you could use 10 of these bulbs on one circuit (ie half the power, being 20w x 10 = 200w), but as they are 20w equivalent to 100w, this would effectively produce 10 x 100w of power = 1000w off one light circuit, which would be bright enough to light up a church on a dim day from one light switch alone!
Also note, coming soon: Fully dimmable ballasts for Linear Flurescent Lampts (LFLs) again Varilight are going to set the standard, big companies should take note.
Reduce your carbon footprint today, save the environment and have ambiant lighting around your home or work place.
5 Bulbs, from left to right:
1. Standard incandescent light bulb, slightly modified at the top. 2.Megaman energy saving dimmable LED GU10 bulb. 3. Standard incandescent light bulb. 4. Standard energy saving dimmable light bulb. 5.Varilight Energy Saving dimmable light bulb
Comparison of Standard incandescent bulb to Varilight Energy Saving Dimmable light bulb:
The Varilight Energy Saving dimmable light bulb is approx only 2cms longer than the standard light bulb and so will more often than not fit easily into most lighting scenarios that use to use a standard bulb.
Approx Max sizes:
1. Standard light bulb: 6cms wide, 10cms tall
2. Varilight Energy Saving dimmable light bulb: 6cms wide, 10 cms tall
*** A Further note to be updated soon is that we are now selling the LED Wise GU10 and MR16 LED Bulbs, which have just gone into John Lewis, these are expensive, but terrific at only 3 watts, the energy saving is out of this world, more to follow soon, or call 0800 043 5532 ***
