The Eneloop Batteries are rechargable batteries with a difference, they are pre-charged ready for use and maintain a charge for a lot longer than conventional rechargable batteries. The Eneloop Batteries have recently been improved to allow them to last longer, retain charge for years and to use eco-friendly energy for the pre-charge.

The Eneloop Rechargeable Batteries have been created by Sanyo. They are the first of their type in the industry to be pre-charged, allowing you to use them right out of the packet. They achieve this due to their ability to stay charged for years, an improved Eneloop battery will retain 75% of it charge after being stored for up to 3 years. This allows you to be to able to charge your batteries once drained and leave them charged for use without worrying about their charge levels, helping to prevent unneeded energy top ups.

The improved Eneloop batteries can be recharged roughly 1500 times, helping to extend their useful life significantly. The batteries are pre-charged through electricity from solar power, helping to add an additional green benefit to them.  The Eneloop Rechargeable Batteries help you to use battery powered devices with increased peace of mind. They achieve this by staying charged which helps to conserve energy needed to ensure working batteries, having a long life of use, and through using solar power for their pre-charge.

The ReZAP Battery Engineer revolutionizes battery charging as we know it. The charger allows you to charge rechargeable batteries and non-rechargeable ones, even at the same time! This technology signifies an end to disposable batteries only surviving one use.

The ReZAP Battery Engineer can be used to recharge all the common domestic battery types, Alkaline, RAM (Rechargeable Alkaline Manganese), Titanium, NiCd (Nickel Cadmium) and NiMH (Nickel Metal Hydride). The sophisticated charger has a microprocessor control within it, this allows the charger to sense what each battery is in each bay, and supply it with its optimum charging of electricity. This means that the charger can charge any mix of batteries at a time, both of type and of size. It can be used to charge a wide range of sizes and shapes of battery, for example it can charge AA, AAA, AAAA, C, D, N, 9V, 6V and many others.

The charger can charge a mix of battery types and shapes at once providing each one with exactly what it needs. The makers believe that the charger can even benefit normal rechargeable batteries (NiCd and NiMH) because of how each battery is individually custom charged. They believe that it can increase the amount of charges the batteries can take, allowing NiCd to charge up to 1000 times compared to about 800 times using standard chargers, and allowing NiMH up to 600 times compared to about 500 times using standard chargers.

The charger allows non rechargeable batteries to be charged up to 15 times, depending on what type and make they are. This helps to prolong the life of these batteries, helping to reduce the numbers of them needing disposal. Due to the use of the microprocessor, you do not need to know what battery type you have as there is no need to select a switch for each one – everything happens automatically.

The ReZap Battery Engineer also comes with 4 AA to D-sized battery converters, these plastic covers allow you to use AA batteries like D batteries, to help reduce the number of different types of batteries you need to purchase. The charger allows you to prolong the life of all batteries, be able to charge a mix of types and sizes together, and helps to make recharging batteries a simple process.

The ReZap Battery Engineer costs just $49.99 with free shipping.

Even if you’re as eco-friendly as possible, you probably still need a few batteries. Don’t you find it really annoying when you need a battery, but you just can’t find any? It’s just as annoying when you have no idea what condition your batteries are in either! The Battery Organiser and Removable Tester is a simple gadget that allows you to store all of your batteries in a single place within a neat rack. To make it really useful, you can also test your batteries in the same place!

By keeping your batteries all in the same place, it makes it much easier to find them again. Even if a battery is not fully discharged, you can still use it in some devices. When your batteries are completely dead, you can recycle them or try charging them in a battery wizard.

The rack measures 30cm by 30cm (12 inches by 12 inches) and can store up to 66 different batteries including D, C, AA, AAA, PP3 plus some space for some button cell batteries. The organiser is available for just $11.99.

Fuji have released a new battery product called the Fuji EnviroMax Eco-Respectful Batteries. The batteries have been designed to be equivalent or better in performance compared to conventional batteries, but being 100% eco-friendly. The batteries contain no harmful mercury or cadmium compounds, nor are they packaged in harmful and non-recyclable PVC. Essentially, if they were disposed of in normal waste systems, they wouldn’t harm the environment.

It’s about time that someone re-designed batteries to be more eco-friendly. Fuji are making a big deal of the fact that their manufacturing process does not release any ozone depleting compounds and they operate under strict standards of environmental responsibility.

The batteries are no more expensive than conventional batteries, and are available in all the standard sizes (AAA, AA, C, and D). You can get the batteries directly from Amazon.

We seem to take batteries for granted these days, barely giving them a second thought. Most gadgets need batteries in one form or another, and most batteries are not great for the environment. Rechargeable batteries reduce the number of one-use batteries that we use, but rechargeable batteries still use harmful materials.

Well here are some interesting facts about batteries to encourage you to think a little more carefully about what batteries you buy.

1. The First Batteries

The first battery was created by Alessandro Volta in 1798. The first rechargeable battery has been around since 1859, when French physicist Gaston Plante invented the lead acid cell. The lead acid cell is still used in cars today.

However, evidence of batteries dates back to over 2000 years ago. In 1938, Wilhelm Konig discovered in Iraq a 5 inch pottery jar containing a copper cylinder encased in an iron rod. This is believed to be an ancient form of battery.

2. Rechargeable Batteries

Batteries work due to a chemical reaction inside the battery that causes electrons to flow from the negative to positive terminal of the battery. When all of the chemicals inside the battery have reacted, the battery is spent. When you recharge a battery, you’re essentially reversing the chemical reaction using electrical energy.

3. Battery Energy Usage

The energy used to manufacture rechargeable and single-use batteries is 50 times greater than the electrical energy they produce when been discharged.

4. The Memory Effect

This is an effect that nickel-cadmium (NiCad) rechargeable batteries suffer from. If a NiCad battery is recharged before being discharged fully, it ‘forgets’ that it is able to discharge any more energy.

For example, pretend a battery is capable of storing 100 units of energy. You use 40 units, then charge the battery up again to 100 units. In your mind, the battery contains 100 units again, but the memory effect means the battery essentially can only release up to 40 units of energy.

5. No Battery Lasts Forever

All batteries, including rechargeables, eventually die. This is because the chemicals inside the battery degrade over time and with usage.

6. UK Battery Regulations

From 1st January 2010, all manufacturers and importers of batteries in to the UK will be responsible for the cost of collection and recovery of waste batteries. Thankfully, there are battery recycling services who will handle the battery recycling for you. It won’t be long before other countries start to follow this regulation too.

7. Mercury in Batteries

The single largest source of mercury metal is found in household batteries, particularly in alkaline and button cells.

Legislation from the EU Parliament, namely WEEE Directive 2003, states that manufacturers of alkaline batteries have made a commitment to remove all mercury from batteries. However, mercury is an integral part of button batteries and cannot be eliminated completely.

8. Nickel Cadmium in Batteries

One NiCad mobile phone or power tool battery is enough to pollute 600,000 litres of water! That’s equivalent to a third of an Olympic sized swimming pool.

9. Losing Charge

Rechargeable batteries will lose a percentage of their charge each day when left off the charger. Therefore try and charge rechargeable batteries hours before you intend to use them.

You should also avoid leaving rechargeable batteries discharged for long periods of time, otherwise the batteries will degrade much more quickly when left discharged for 6 months or more.

10. Terms such as “Heavy Duty” are misleading

Since there are no real industry standards for batteries, many terms used by battery manufacturers have become misleading marketing hype. Although the terms didn’t start out as being misleading, “Heavy Duty” batteries are often the least powerful batteries you can buy!

Further resources and facts

I used a number of resources when compiling facts for this article. This is a list of all the resources I used:

• Energizer – Battery Care
• Rebatt UK – Battery Facts
• How Stuff Works – Batteries
• Battery Back – Battery Recycling

A chap by the name of Knut Karlsen has been playing with flexible solar panels, and developed a basic solar-powered rechargeable battery concept. Using some specially cut solar cells, the cells have been wrapped around NiMH rechargeable batteries.

When the batteries are low, you just need to put them in the sun for a bit. The solar cells only act as a trickle charger, and there’s no facility to check when the batteries are full, but the idea is neat and simple. It wouldn’t be too difficult to create batteries with a chip-on-board (COB) circuit that could fit within the casing of the battery. This circuit would then prevent overcharging of the batteries.

However, in the name of efficiency, I think it’d be better to charge the batteries using an external charger. Not only would it be cheaper to make the batteries, but you could optimise the charging time of the batteries. Additionally, what if the solar panel on the battery breaks? That battery would then be useless.

One of the many ways of being more eco-friendly is to appreciate the great outdoors more. Walking, jogging and cycling are fantastic ways to enjoy fresh air, the environment and get a little exercise. The IZIP Trailz Enlightened bicycle has a special power-assisted cycling mode, which can push you along without peddling up to 18 miles an hour, up to a possible 23-30 miles!

The bike’s downtube (i.e. the bar connecting the front and back of the bike) conceals high capacity Nickel Metal Hydride (NiMH) batteries. When these batteries are charged, they drive a special motor that assists you with your cycling. Just think of the extra help you get when trying to climb a steep hill! When you want to use pedal power, just switch into normal cycling mode.

The special power sensor allows you to adjust how much power is exerted by the motor too, so you’re in complete control of how much effort you save yourself. What’s great about the IZIP Trailz Enlightened model, is that it looks so stylish, you’d need to know what you’re looking for to notice the power assistance.

If you compare it to the entry level model, the IZIP Trailz AL Electric Bike, you’ll notice that the motor is considerably more obvious. Therefore if you want the boost in speed on your bike, but don’t want anyone to know, head for the higher-spec model! Power-assisted bikes are great eco friendly gadgets, combining practicality with style.
