SANYO's next-generation nickel metal hydride battery ‘eneloop’.
Batteries have a property to release the stored energy in small amounts (this phenomenon is called ‘self-discharge’). This property is particularly noticeable in rechargeable batteries such as Nickel Metal Hydride Batteries etc. as compared to dry cell batteries, hence disabling rechargeable batteries from becoming batteries that ‘customers can use immediately after purchase’. For this reason, rechargeable batteries couldn’t be used unless charged after purchase and so lagged behind dry cells in convenience. This new product’s main property is that it has introduced great improvements in self-discharge properties (residual ratio after one year of non use is 85%*4, in temperature conditions of 20 degree Celsius according to SANYO research). Through this breakthrough development, SANYO has realized a rechargeable battery that can challenge dry cell batteries in user-friendliness through features such as making possible use immediately after purchase or once charged, its ability to be used anytime.
Product Features
- eneloop 4 pack AAA 800 mAh Pre-Charged and Ready to use right out of the pack.
- Very slow self discharge maintains 85% residual capacity after 1 year of storage*and 70% residual capacity after 2 years of storage* Based on SANYO's simulation when stored at 20* C
- Greater Power and Better Performance in Low temp than Alkaline. Internal test results shows eneloop gives up to 4.4 times more shots when using a DSC than standard Alkaline and offers stable superior performance in low temp environment such as ski areas.
- Reused up to 1000 times* and no need to worry about memory effect,able to charge only the amount you need.*IEC 61951-2 Test Condition. Cycle life may differ because of conditions and applications.
- eneloop combines all the features of an alkaline battery (Ready to Use) with the benefits of Rechargeable (Reusable)
- Excellent for RC Transmitter (usually require 8 x AA Cells)
Low self-discharge - the key-advantage
What makes the eneloop unique?
The key-advantage of the eneloop compared to usual rechargeable batteries is its extremely low self-discharge.
Retains Capacity... Even After 12 Months
Once charged, eneloop retains its charged capacity even after 6 or 12 months of storage
(90% of Charged Capacity retained after 6 months, 85% Capacity after 12 months).
eneloop batteries are pre charged and is ready for immediate use after purchase, straight from the pack. Just like Primary Batteries. There is no need to charge-before-use.
Comparison of remaining capacity over time
Once charged, eneloop keeps its charge even if you store it for 6 or 12 months.
( 90 per cent of the charge after 6 months, 85 per cent after 12 months )
For a rechargeable battery this is a revolutionary advantage.
No more worries about the state of charge of your battery.
Just, charge them and keep them.
Even after months you will still have an almost fully charged battery.
In contrast to a disposable battery the eneloop can be charged 1000 times. This saves the environment and your purse.
Thus one eneloop saves the waste of 999 disposable batteries.
