Why Sanyo eneloop?



Sanyo eneloop rechargeables can replace an entire kitchen drawer's worth of dry cell batteries
You already know the benefits of using conventional rechargeable batteries. But Sanyo eneloop batteries have advantages over other rechargeables that put them a step ahead.

Sanyo eneloop batteries are an excellent choice for your rechargeables because:

  • They can be used right after purchase
  • They consistenly yield high performance
  • They have a long shelf life with no loss of energy
  • They can be used everywhere
  • They are environmental friendly


Self-Discharge: Why Conventional Rechargeables Don't Cut It

Conventional rechargeable batteries have numerous advantages that make them great to use for your portable electronics. But they also come with certain disadvantages. After purchase, rechargeable batteries have to be charged before they can be used. And once charged, rechargeable batteries lose the stored energy rather fast. The charging takes quite long and rapid chargers are expensive. Not only that, but continuous charging or frequent charge to "top off" the lost energy (without complete discharge) can destroy the battery.

All these negative attributes have one root-cause: self discharge. Self-discharge means that a charged battery slowly discharges itself without any equipment consuming any current. This is the reason for rechargeable batteries being sold in a discharged state. And this is the reason that keeping charged batteries for some time did not make any sense. When you needed them, the energy was gone. Sanyo eneloop batteries have an extremely low rate of self-discharge, which means they hold their stored energy for a very long time--charge your batteries once and put them in your kitchen drawer, and over a year from now you'll still be able to use them right away, without needing to charge them again.

Under the Hood: How eneloop Controls Self-Discharge

How can the self-discharge in the eneloop be so reduced? The self-discharge of Ni-MH batteries is caused by three main reasons:

  • The chemical decomposition of the cathode
  • The natural disaggregation of the anode
  • Impurities of the anode
The chemical decomposition of the cathode has been reduced substantially by the use of a new hydrogen-absorbing superlattice alloy. As an additional benefit the superlattice alloy increases the electrical capacity of the battery and reduces the internal resistance, which allows higher discharge currents than conventional rechargeables. Also, the anode has been strengthened by the improvement of the electrolyte composition, which reduces the natural decomposition by increasing the oxygen over-voltage.

This gives eneloop batteries a number of advantages over traditional alkaline batteries, including up to four times more power when used in a digital camera, high performance even at low temperatures (down to 23 degrees F) during your winter vacation, and a vast cost savings in the long run. The eneloop advantages are even more glaring when compared to typical NiMH batteries: not only are they ready for use right out of the box, but they generally last longer than most NiMH batteries (continuous and frequent recharging can destroy other NiMH models) and save both time and money (traditional NiMH charging is slow when you're in a hurry, while rapid chargers are expensive). All told, you can recharge eneloop batteries up to 1,000 times without experiencing a "memory effect"--just charge the amount you need and you're set.

Great batteries, hoped for charger mentioned in details4
The Sanyo Eneloop 4 Pack AA with Charger is a great buy. What's better is after opening, just pop into your electronics and away you go (batteries are precharged). Only downfall was that the details said that it was a different charger where you can charge one battery at a time. The charger that came with this, you have to charge in pairs. Luckily my remote, wii peripherals, etc. all use paired batteries.

broken box , good batteries...4
Batteries were good (this is my second time to buy "eneloop" batteries)but the box was broken (the handle part) and the seller used a strip to fix it........It was too much work to send it back to exchange the box to me.

Good value5
Ordered this as a gift for a friend enroute to Afghanistan. It arrived very quickly and he was pleased to receive it. Not sure about its use since he took it with him, but am sure he'd let me know if there were any problems.
