The Green Certificate System and eneloop

Panasonic eneloop pro aa

As part of our participation in the Green Certificate system, we use solar power to charge eneloop batteries prior to sale.

Panasonic Eneloop Pro Review

Recharging your eneloop battery using solar energy will help in our aim of creating a “Clean Energy Loop”. The earth receives the same amount of clean, inexhaustible energy from in the sun in one hour as all the energy expended in the world in one year combined. We are working to find new ways for people to harness this power in their daily lives.

We still have a long way to go before we can rely solely on solar power, but it’s our ultimate goal to eventually be able to live on renewable energy. We want to reduce the cost of solar power, and increase the amount we can generate. The Green Certificate energy-trading system is one way we can work towards achieving both those goals.

We proudly participate in the Green Certificate program to help bring us all closer to a Clean Energy Loop lifestyle. Those who choose eneloop batteries can feel they are contributing, like us, to the future of solar power and a cleaner lifestyle.

While it might not happen overnight, we are taking significant steps towards a world powered by clean, sustainable energy, and a better future for our children.

Green Certificate Trading System

Electricity generated by renewable means has significant environmental value, such as reducing the amount of damaging carbon emissions put into the atmosphere, and the use of energy in a more efficient way.

By participating in the Green Certificate trading system, electricity consumers can own environmental “value” in tradable certificates by paying a premium on the regular price of electricity. The owner can then announce that fact to the public.

Purpose of Green Certificates

High

- Owning Green Certificates contributes to positive environmental action by companies and local governments that have difficulty in owning green power generating facilities.

- Electricity suppliers can sell the environmental value as Green Certificates, and use the money to invest in “green” power-generating facilities. This will eventually lead to an increase in the amount of green power available.

FAQ

Q Can eneloop be charged up to 2,100 times?

A

This is an estimation based on test results for battery life according to IEC standards (for the number of times charging and discharging). The number may vary, however, depending on how the batteries are used. Battery life does decrease slightly in relationship with the number of times the battery is recharged.

Q Is it possible to use eneloop worldwide?

A

Yes, if your Panasonic charger has a function called Auto Voltage to handle any voltage between 100 and 240 V. You will likely need a plug adapter for your charger in other countries.

Q My equipment does not work. Why?

A

It may be due to the following:

Cause 1: Batteries are not charged

Your eneloop is a rechargeable battery. It is pre-charged when you purchase, but once drained it needs to be recharged in order for you to use it again. In the event your charged battery cannot be used, it’s possible that the batteries were not charged properly or the batteries have discharged because they were kept in use for too long. Try charging them again.

Cause 2: The terminals may not be clean

Touching the battery with your fingers may leave dust or grime on the surface of positive and negative terminals. This causes the electrical resistance on the surface of the electrode to increase, which affects battery performance. If this happens, clean the terminals with a dry cloth.

Cause 3: Battery over-discharged

Appliances without an over-discharge prevention function can sometimes cause batteries to over-discharge. For example, use in a low-current-draw LED light until the battery runs out can cause it to over-discharge, and later the battery won’t recharge correctly. Recharging the battery 2-3 times can remedy this problem, but if it persists, unfortunately your battery’s life is at an end and we recommend seeking a replacement. Continuous over-discharging causes damage to the batteries. We recommend recharging the battery when you see signs of decreased performance, for example when luminous energy becomes low when used an LED light.

Q What happens when you swallow a battery?

A

If you or a child has swallowed a battery, immediately head to the nearest emergency room and bring the battery packaging or device if possible.
Take these measures into account:

  • · Stay calm, but act quickly. Unless the battery is lodged into the esophagus, severe and/or life-theatening effects are less common
  • · Avoid eating or drinking unless a medical professional has directed otherwise
  • · Do not force vomiting yourself

Q What to do when rechargeable batteries heat up while using?

A

Panasonic Eneloop Pro Amazon

When rechargeable batteries are over-discharged with continuous high current, abnormal heat could be generated. If the batteries become excessively hot, stop the appliance immediately from running since it damages the batteries. After spontaneous cooling the batteries will be fit for use again.
When rechargeable batteries generate heat immediately after inserting them into an appliance, there is the possibility that the batteries will short circuit when contact is made with the appliance’s terminals. This could cause the batteries to leak and explode.
If this happens, cover the batteries with a thick cloth immediately and remove them from the appliance quickly without scattering any of the leaking liquids. Then, let the batteries cool naturally in a safe place, after which you should put them in a plastic bag before depositing them into a recycling box at an electrical store.

Q How to increase battery life?

A
  • · Leaving empty batteries in the device for a long time without charging them will cause serious damage to the cell electrode (over-discharge) and will shorten the battery life, so avoid doing so.
  • · Charge the batteries frequently. In theory, batteries should be recharged when 70% of their capacity has been consumed. This will ensure that there is no possibility of over discharging the batteries, which is a major cause of cell damage.
  • · Do not use batteries at high temperatures as this increases the internal pressure inside the cell, which includes liquid loss and a shorter life span.
  • · Group the batteries together. When the batteries are grouped together for a device, e.g. 4 x AA for a toy, means that the cells will discharge simultaneously. If a battery is removed for use in another device, ad.es to operate an LED light and then put back into the toy, this translates into 1 battery out of 4 which has a different power level than the others. Because of this, the cell will deteriorate and discharge more quickly.
  • · In order to maximize the performance of rechargeable batteries, it is important to use cells of the same conditions. Use batteries with the same characteristics, such as:
  • · same product code
  • · batteries purchased together
  • · same charging / discharging time
  • · The use of rechargeable batteries with different conditions will increase the performance gap between the cells which will lead to unnecessary deterioration of the batteries and their duration. It may be useful to mark the batteries with a permanent marker so that they can be differentiated.
  • · Make sure the battery cell terminal and the charger are cleaned frequently. Repeated use of rechargeable batteries will cause (invisible) contamination (such as grease or dust) on batteries and charger, which will affect Panasonic products in terms of performance. Consequently, such dirt could obstruct the charge of the cells together with the reduction of the battery discharge time. For these reasons, Panasonic invites its customers to frequently clean their batteries and their chargers using a cloth.

Q How many mAh is in AA battery?

A

The mAh capacity of an AA battery depends on the type. For Panasonic eneloop rechargeable batteries, the AA minimal capacity is as follows:

  • eneloop AA: 1900 mAh
  • eneloop lite AA: 950 mAh
  • eneloop pro AA: 2500 mAh

Q What does mAh mean on rechargeable batteries?

A

The capacity of batteries is indicated as XXXX mAh (milliampere/hour).

The formula for calculation is as follows:
Capacity (milliampere/hour) = discharge (milliampere) x discharging time (hour)

E.g. Take a Ni-MH rechargeable battery with a capacity of 2000 milliampere/hour.

If you insert this battery into an appliance which consumes 100 milliampere current continuously, the operating time of the appliance will be around 20 hours mathematically.

However, this is just a guideline since it varies depending on the performance of the appliance or the conditions it is used in.

Q Do I need to charge and discharge batteries before use to get optimal performance?

A

All of our eneloop rechargeable batteries are fully charged at our factories before shipment. However, during shipment, batteries may naturally discharge due to the change in environment or temperature. It is recommended to charge a rechargeable battery before use if the situation allows for it in order to reduce damage to the battery.
However, if you have no choice but to buy and immediately use the batteries, feel free to do so. The optimal capacity of the battery will be reached approximately after 2 charge and discharge cycles.
