EnergizerRecharge Universal Rechargeable D Batteries, 2 Pack

This is an outstanding charger. It's not the cheapo wall unit that holds only four batteries. This Energizer Family Charger holds twice as many batteries, and many more types. Even better, it can deliver a different level of charge to different batteries of the same type - so it's OK to charge your new Eneloop AA's along side your exhausted Duracell AA's. And those four fill just half of the charger. In the other half you can charge AAA, C, D, or even 9V batteries at the same time. And because it's a closed-lid device, the batteries are all kept in a single place protected from dust and ready to go at a moment's notice.Add the lid's separate charge-level indicators for each individual battery, and this charger beats every other consumer-grade model I have owned or seen. It even beats the professional-grade models we use at work.So why are some buyers' experiences negative? I'm convinced it's the batteries themselves. I have been using rechargeables for six years now, enough to know that all batteries are not equal. One obvious difference is the milli-amp hours rating on the package. But as engineering tests have shown, the actual batteries delivered often don't match that rating. But the most important factor isn't shown on any measurable rating on the package. We consumers want batteries that hold their charge after charging and can be recharged over and over without degrading. Without going too depp into the technologies involved, I'll state confidently that my Energizer and older-model Duracell rechargeable batteries fail to meet these expectations. Lots of people blame the charger, but it's the battery. Eneloop is hands-down the best at meeting onsumer expectations, and with Eneloops in this Energizer charger one achieves the dream. White-topped Duracells rank second, if you get a good batch.One telling sign is a battery set that ships pre-charged. That's a strong indication that the batteries themselves hold their charge for months, where lesser batteries hold a charge only a couple days after charging. This is true of my Energizer rechargeables even when I leave them in the charger for that "trickle".So my experience before Eneloop and a decent charger was the anti-dream. I invested in rechargeables, but the family had no confidence. The charged batteries all lost their charges by the time they were needed. Whenever the family needed replacement batteries in a toy, flashlight, remote control, or video game, my only viable answer was "I'll charge some overnight so you can use them in the morning". Therefore the wife regularly bought conventinoal batteries so we'd always have a ready-to-go solution, meaning I was receiving on return from my investment in rechargeables.Now it's all better. I have a dozen batteries upstairs ready for use immediately because they charged thoroughly and still hold their charge. We all have confidence in the current rechargeable solution, and we never buy conventional batteries anymore.In summary: If you want the best rechargeable battery experience possible today, get this charger with Eneloop batteries. If you can only get one or the other, the Eneloop batteries are the most important element. This charger is just a terrific addition to the capability offered by superior rechargeable batteries, primarily because it concurrently charges different batteries from different starting levels. The complete range of sizes is a huge plus, but only if you use rechargeables in all those sizes.

They last longer than I thought they would.

Works great

Energizer Rechargeable Battery Charger for C Cell, D Cell, AA, AAA, and 9V Rechargeable Batteries.For the environment, decided to install rechargeable batteries in all my electrical units requiring batteries. My only complaint is that rechargeable batteries still don't hold a charge as long as the non-chargeable batteries. So sad. :((This is a great unit, however, and worth the expense.

DO NOT BUY the CHARGER! The springs keeping two of the four bays snug enough to charge batteries broke shortly after purchase.The seller would not respond to email. So I contacted Energizer.They had me send pics of the defect and a copy of receipt. After that, they stopped responding to my messages. I have sent them DOZENS of emails with the pics of the defect and a copy of the receipt over the course of over a year, and still they don't reply.I've even tried to contact Energizer corporate office. No one is responding anymore. It was defective and NO ONE will refund, replace or even respond.The only thing I was able to find out was that Energizer had outsourced their customer service overseas shortly after my purchase. This is why I received replies at first asking for a copy of the receipt and pics of the defect, but no replies after that at all. I had tried calling their customer service number but could not understand anyone. When I asked to speak to a manager, they said NO. Now they no longer even have phone support.Energizer customer service is no longer existent.Corporate has not responded to emails, phone calls or faxes for over a year.I wasted money on a defective item that you can't even get support for.Do NOT waste your money. Get a different brand of CHARGER from a different seller.

They charge and work. They are much much lighter than Amazon basics (probably due to thinner walls). Amazon basics weigh x2 compared to these.

Dependable rechargeable. Already bought a few so this was a no-brainer purchase.
