Energizer Recharge Universal Rechargeable 9V Batteries, 1 Pack

Seems to hold a charge well. Good price.

I’ve had these since August and I noticed a big change. At first, it held a good charge, but that quickly changed and will only hold a charge for about a week. Now it’s barely a week. It’s really aggravating going up and down the ladder for that nightlight too often. My mom is not young, and I’m not that young anymore… so, for anyone of my age and older to keep going up and down, the ladder is ridiculous, and I wish this thing could just hold a damn charge. I expected better out of this brand.

Very good quality and value! Just bought new batteries so I won't need it for awhile. I like to be prepared!

Easy to use and remove. Works great and hold a good charge. Worth the price.

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.

Always meets expectations of store bought rechargeable batteries. I decided to subscribe because we never have enough batteries. I recommend buying!

This charger is not worth $45 bucks, its very "dumb" appliance. It has a single charging indicator light, that is confusing, it has a long green light strip and it turns off when charging for some set amount of time. To charge an additional amount, you have to unplug and re-plug the charger. Check out the user manual before buying, it only charges up to a certain mAh capacity. I bought Amazon Basics rechargeable D-cell NiMH batteries with 10,000 mAh each, but this charger only charges up to 2500 mAh for approximately 5 hours, so I have to unplug and replug approximately 4 times to get my batteries charged up to the 10,000 mAh capacity.

Súper buena idea comprar pilas o cargador recargables no sabes lo que te ahorras en pilas más cuando tienes niños y usan juguetes con pila

I recently switched to Energizer Rechargeable D Batteries for my Nerf Rival Blasters, and the difference has been remarkable. Compared to standard alkaline batteries, these rechargeable ones are significantly lighter, which enhances the overall handling of my blasters during extended play sessions. One of the persistent issues I faced with alkaline batteries was their tendency to weaken over time, leading to a noticeable drop in performance. Instead of continually replacing them and contributing to waste, I found that with the Energizer Rechargeables, I can easily monitor their performance and recharge them as soon as I detect any decline in power. This not only extends the life of my batteries but also ensures consistent performance during intense battles. Overall, these rechargeable batteries are a game-changer for anyone using high-drain devices like Nerf blasters. They offer convenience, sustainability, and reliability—all crucial for maintaining the excitement and performance of my games. Highly recommended if you can get them for a good price!

Producto perfecto de buena calidad

Good product

It's Energizer, well know brand, high charging capacity

I've had this in my smoke detector for the past year, and the voltage is still holding up well even though I haven't recharged it. So, although this battery doesn't state it's low-self-discharge, it appears to be. It may not be cost-effective (compared to alkalines) in a low-drain device like a smoke detector, but I know I can charge it up and it's like having a fresh battery always on hand. Plus, NiMH batteries won't leak and ruin your device, like alkalines can. This would be very cost-effective in something that uses more power, like a mic or remote for a RC toy.
