Side by Side Comparison of: Energizer

My wife uses them to operate a portable fan at her work station. These batteries are holding their charge for an acceptable time period. No problems.

These rechargeable batteries last long and is easy to recharge. I have been using them for a few weeks in my portable lamps and flash lights, and find the convenience of cordless lighting so nice for detailed close up work.

These are great.... I play a lot of video games and these hold a charge longer than any other I've tried.... and I've been using them for about 1.5 years

HOW TO CHOOSE A RECHARGEABLE BATTERYSince rechargeable battles have an enviromental impact with disposal, you want to buy the ones that work the best and lasting the longest. The best rechargable battery I have used (and I have been using rechargeable batteries for over a decade), are NIMH. THese batteries have the greatest advantages and the few disadvantages (as detailed below).My choce is base on 3 basic principles: Capacity, performance and self-discharge rate.Capacity is measure in mAh - think of this as the gas tank in your car. The higher the mAh, the bigger the "tank" and the longer the battery will work.Performance is a measure of ability to last in energy guzzling devices such as gaming consoles and digital cameras. Performance of NIMH batteries is nearly double that of the usuable disposable alkaline battery. This is similar to the need for high-octane gas in high performance cars.Self-discharge rate is how fast a fully charged battery loses its power ("leaky" gas tank). There are 2 types of NIMH batteries, LSD (low self-dischage) and non LSD. he LSD NIMH batteries will retain 75% of their charge for a year or longer. Non-LSD NIMH batteries lose about 15% of their charge in a month. Since I mostly use rechargeable batteries is "battery eating devices" and rarely store my batteries for more than a month, I use the non-LSD version.so now you have the information to look at the different paramenter of NIMH batteries and determine the best value for your battery usage.In my own experience, many LSD NIMH batteries have not performed as well as regular NIMH batteries. So I prefer the regular NIMH type. Brand is also important. I find energizer brand to be high quality, long lasting and reasonable priced.

I've been using these batteries for over a year and a half now, and they're still going strong. I've got them in remotes, clocks, and flashlights, and they continue to recharge time and time again. They also still hold their charge for what seems like the same amount of time as on the day I bought them. No problems, no dead units, so far so great!

Great batteries for a great price! I use these mostly for my XBOX and Wii controllers. I always have 4 in the charger and just swap them out whenever they run out of power. So far they seem to be keeping the same charge after many uses. These are a much better option then buying disposable batteries and helps keep those nasty chemicals out of landfills!

I bought these because I thought they would be true D cells, being sold as Energizer batteries. I found they were the lightweight variety, which can be had at a much lower price at HF store, and are essentially AA batteries in a D battery size shell. They are 2500 mAh at 1.25 V whereas alkaline D cells are 12000-18000 mAh at 1.5 V. I bought them in a hurry, as we were facing an impending hurricane, and D cells were scarce to non-existent in the stores. Fortunately, they functioned in my Maglites, and I take responsibility for not noting their output carefully. They are fine for my purpose, but just note that they will not last as long as an alkaline battery, and rechargeable D cells can be had with higher mAh output. I believe all rechargeable D cells are 1.25 V, however.

They're rechargeable batteries. They recharge and hold it well.

Good quality, but seem to need recharges more often than my Eneloops.

So far, so good.... I haven't used these batteries long, but they were highly rated. I thought the size would keep me from using them in some of my remotes... not so... They fit fine

As far as rechargeable go, these are darn good. The only thing I can complain about is that I find that every brand of rechargeable battery I have tried does not last as long as a fesh set of nonchargeable. Duracell or Eveready Akaline Batteries in the same device.

We continually purchase additional Energizer rechargeable batteries. Simply doesn't make sense/cents not to do so. By watching the prices (as they do fluctuate), we typically buy them at a fairly good and discounted price. By doing this, we also help in a small way, to keep additional and potentially toxic chemicals out of the environment.

I'm sure these batteries are fine, and they were a great buy compared to the others. However... the package is all in Spanish! Hopefully there's nothing important I need to know. Many packages are bilingual, but not this one.

These are only 1.2 volts. They are not strong enough to run some things. I have a night vision scope that takes 4 batteries and these will not operate the night vision or allow me to program the scope settings.

I have used these batteries in the past and they work quite well. However they are suppose to be pre-charged and out of the three packages of 8 that I purchased all were dead. They are suppose to hold a charged up to a year. I wondered how old these batteries are and there are no date codes on them or the packages they came in. I hope they last the full five years as stated.

Not a terribly long charge. Our light-up baby bouncer lasts 3-5 days depending on use. In the baby swing, it lasts maybe two or three hours? We only use them as back-ups when our longer lasting batteries are charging.

They are as good as any other rechargeable battery from what I can tell so far. But they were supposed to come fully charged; they were not. They had to be charged before use.

This is still a good battery but it only has half the mAh of the ones I have, which means it doens't last near as long. I should have read the fine print!

I bought four D-cells to use in an LED closet light. Three of the batteries appear to work fine but one of them discharges quickly and takes about 3 times longer to recharge. I have found no way to contact the seller to report the issue, so it looks like i'm stuck. Guess I'll be shopping for another brand soon.

Haven't tried rechargeable batteries for over 20 years due to the lack of power and short battery life that was synonymous with rechargeable. I felt like there was a resurgence of rechargeable batteries on the shelves in stores in the last few years so decided to try again. Nope, they haven't changed a bit.I tested the batteries with identical LED candles, that require 2 D cell batteries, set to a timer to run for the same amount of time. The rechargeable lasted less than a week. I recharged the rechargeable D cells, swapped which candle got the rechargeables and tested again, with the same week-old standard batteries. Again, less than a week from the rechargeables. The standard batteries are still going, now past their third week.I've got a handful of these candles around the house but it was pricey to keep them going on a regular basis. I was hoping the rechargeable would mean I could let them use the timer like they're supposed to and I could enjoy them every night instead of just on special days when I felt like turning them all on. But, the rechargeable batteries won't even make it through two weekends without a charge.

I did recharge the batteries. I got dead battery signals. Only once use? 2 stars!

The product description is incorrect - these are 800mAh, NOT 2300mAh. So I am disappointed and feel that I had been mislead into buying this product over others. If the product was correctly described then there are better value alternatives.

Bought these to power a Hot Wheels race track which takes a good bit of power (the regular alkaline D cells get used up in about a week). Unfortunately, these rechargeables don't have the output the power the racetrack, the cars can't make it all the way around. If you're buying for something which needs a lot of power I would skip these.

I have to agree with the other reviewers who've said these batteries are weak. They just do not last. I ordered two packs for use in my son's baby swing, he's 4 months old. Other batteries lasted several days, including some other rechargeable batteries. However, these just flat out were terrible. They lasted about half a day. So I recharged them again and they still only lasted about a day. So they do function, but they just don't seem to have the punch that others do. Now I didn't do any kind of voltage test or whatever, so I can't offer any scientific data. But my observation is that they are not as effective as normal alkaline D cell batteries or other D cell rechargeables. I'd pass on them. However, I will add that Amazon was VERY gracious with their refund policy on these. I requested a return refund and they simply refunded my full order cost without requiring me to return them. So good deal.

I purchased these batteries in conjunction with the Energizer Recharge Pro Charger. As these batteries came precharged, I used them in my electronic device. After draining the batteries, I attempted to recharge them in the Pro Charger, but the charger indicates a 'bad battery'. I tested the charger to see if it charged other Energizer batteries (both AAA and AA) and the charger worked. Energizer needs to have better quality assurance in their battery products.

Cheap trash. You are better off with almost anything else. Energizer took some AA batteries and wrapped them up in a D size shell. You are better off burning your money than buying this bullcrap.

These 2 batteries used in a HAP75 SMOKE GRABBER SMOKELESS ASHTRAY. BATTERIES DISCHARGED IN 4 HOURS! DURACELL ALKALINE BATTERIES LASTED 150 HOURS. BUYING EBL. Also batteries got hot in EBL CHARGER.

The batteries charges fine the first time, the second time I just got a blinking/ beeping X saying they would not charge. I feel like I wasted my money.

So I use a lot of D batteries. D batteries are expensive so I foolishly invested in 16+ of these and some AAs as well and two chargers. THESE BATTERIES WILL NOT HOLD A FULL CHARGE OVERNIGHT.In use they last me for my purposes for 4-5 days. Regular Alkalines lasted in the same application for 3+ weeks !!!As many here have said in their reviews, these batteries are a rip off.It takes a big man to admit he got conned by a little pink bunny rabbit who keeps going and going.

These batteries hold a charge very poorly. The charge is spent very quickly. The charge is a fraction of alkaline D batteries. I was using alkalines in a baby swing and they would last about a month. After going through 3 sets I decided to get rechargeables. These Energizers last only 2 days in the baby swing. Not worth the price. I am surprised Energizer sells such a poor product. These Energizers are only 2500mAH. There are others that are 10000mAH. I am going to try those.
