Generally, when a non-rechargeable battery runs out of power, it retains in regards to 20% of energy. When you connect it to an alkaline battery charger, this energy is reactivated and will last longer. When activated, the charge will stay at 20% but will still be competent to run the battery. After this original reactivation, they may be recharged 3 times more to greatest or most complete or best possible capacity. After this, the battery will have been exclusively worn out and needs a replacement. If you can, check for signs of leaks after charging it for the third time. With the added weeks of service, you get to save cash you’d have used to buy new batteries. So to to the full or entire extent utilize your non-rechargeable batteries, invest in an alkaline battery charger. The most standard brand of battery charger in the market is Varta. Varta chargers are universal chargers that are very versatile, capable to charge a range of batteries. It takes 5 hours to entirely recharge a battery using this charger. Each Varta charger has 6 LEDS and a charge timer which helps you to recognise how much energy the battery has at any queer time, the trickle charge and temperatures of cell parts in the battery. The charger will observe polarity and/or alkaline defects and bad cells. It comes with a 3 year warranty. Purchasing a Varta charger warrantees you a UK power adaptor plug. An alkaline battery charger will make sure a longer shelf life for your electronic devices. They are easy to use and an indispensable investment for any individual who owns a number of appliances that run on batteries. When buying one, shop conservatively and pick one that will match your needs. They are readily available in stores at an lowpriced price.

At first, I was very happy about the large current capacity offered by those batteries. But within a few months, I started to notice that they die very quickly in my digital camera. In fact, a set of Sony 2300mAh NiMH batteries I bought one year earlier seems to last much longer when used in the same camera. I recently did some controlled experiments (using the LaCrosse BC-900 AlphaPower Battery Charger) and found out what’s wrong: The Energizer NiMH batteries have very high self-discharge rate. After fully charging all 8 cells and left them on the shelf for one week, five of them lost over 30% of their charge, and the other three lost about 20%. In comparison, the set of older Sony batteries only lost around 10% over the same one-week period. So what this really means is: if I charge up those Energizer 2500mAh batteries and leave them in my camera for three weeks, they will become totally exhausted. I found this kind of self-discharge rate completely unacceptable, therefore I strongly advise against buying those batteries. [Update on April 9, 2007] Instead of the Energizer 2500mAh cells, I recommend buying the Rayovac “Hybrid” 2100mAh cells. They have very low self-discharge rate (see my review on “RAYO 4PK AA”) and are cheaper than the better-known Sanyo eneloop 2000mAh cells. Kodak also sells a “Pre-Charged” NiMH cell with exactly the same spec as the Rayovac Hybrid. The bottom line: Low-Self-Discharge NiMH cells are your best choices. There is absolutely no point in taking chances with older generation 2500-2700mAh NiMH cells now. [Update on Oct 20, 2010] 41 of 43 people found the following review helpful. I rely on two of the excellent MAHA MH-C401FSB smart 2-rate chargers. These charge and monitor each battery independently, not in pairs. Energizer 2500 mAH units were fine for about three months. Then I noticed that devices would be calling for new batteries with little to no use. This has never happened with other AAs NIMH, including those with less than half the advertised capacity. The MAHA charger also started reporting that some of the Energizer AAs were not taking a charge at all. Kept finding that typically one out of four were the problem. Many of the 32 AA Energizers I bought have had problems. Repeatedly have had one battery run out of charge while others still test very strong. Felt pen dots put on discharged batteries showed it was the same batteries time and time again. Have reverted in some cases to 1600 mAH SANYO OEM batteries put in service in Feb 2001 and those provide longer and more reliable performance! In my considerable experience with these 2500 mAH AA Energizers they have been a very big disappointment and, regardless of warranty, cannot be relied upon. 150 of 173 people found the following review helpful. The bicycle light seems as bright as it ever was with alkaline batteries, affording good visibility during night time cycling. And stopping play—er, experimentation—with the LEGO robots for recharging has yet to be a problem.
However, I do have to issue this warning: these batteries are slightly fatter than standard AA batteries. I tried using them in a Mini Mag Light. After I got one battery in the light’s barrel, I realized—too late—that I’d never get the batteries back out. I ended up destroying the Mini Mag Light in order to retrieve the batteries.
If your application is cramped for space, beware! If they do fit, expect good energy for a good long time. |
Shockingly high self-discharge rate!
Shockingly good performance
