Energizer Compact Charger Customer Reviews

I've found these batteries to be WELL worth the money. They are comparable to a good Heavy Duty (Non-Alkaline) set of batteries. I have a program on my palm pilot called FPSUtil3.5 that allows me to track the battery power curve over time:

They don't hold a top end charge for very long: 85% after only 30 minutes But they really hold up well after that: 68% after 2 hrs & 15 minutes (10 minutes of nightlight) - 54% after 3 hrs - 40% after 5 hrs - 38% after 8 hrs (15 minutes of nightlight) - 28% after 10 hrs - 18% (battery warning)after 11 hrs 30 minutes

So, after 11 hours and 30 minutes of power on over a 6 day period with 25 minutes of nightlight use, they are ready for a 5 hour charge... NOT BAD, seeing as to how I'm supposed to be able to charge them 1000 times. I think I'll get my money out of them... ; )

Energizer Rechargeable 15 Minute Charger review

I wish I could give this quick charger a five-star review, but I've experienced some problems with mine. First, it gives off a significant amount of TV interference -- more than any other device in my house except perhaps the microwave oven or vacuum. You will NOT want to use the charger while you are watching a movie! Second, it seems to reject a lot of batteries that still work and that my other chargers have no problems recharging. This is especially true for AAA batteries for some reason. (I have subsequently discovered that the charger rejects batteries that are close to fully charged rather than indicate that they are fully charged. This means that the charger MAY charge the rejected batteries again later, after they have been further depleted.) So -- if you only want one charger in the house, I can't recommend this one. I can however recommend it as a supplemental charger, when it chooses not to be tempermental. On the positive side, I like the fact that this unit has four independent channels, allowing you to charge any number of batteries, from one to four. (You don't have to pair up batteries.) It also has a built-in fan that cools batteries down (quick charging can make them get pretty hot to the touch).

Sanyo Eneloop 4 Pack AA NiMH Pre-Charged Rechargable Batteries w/ Charger

Best Sanyo Eneloop 4 Pack AA NiMH Pre-Charged Rechargable Batteries w/ Charger and Read Consumer Reviews

Once charged, eneloop keeps its charge even if you store it for 6 or 12 months without use / No more worries about the state of charge of your battery

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.
