Rechargeable

It was a good purchase. The batteries charge really fast.It was so convenient to buy this pack, with AA and AAA batteries. I also had to buy some extra AAA batteries, but it's good we can have enough batteries at home.It's good they have a long lasting battery and all the Duracell quality. I hope we don't have to buy new ones in a long time.

Good Duracell quality, quick recharging, long lasting, and pays itself off over time.

The Duracell Ion Speed 1000 Charger is a total game-changer. It comes with 6 AA and 2 AAA pre-charged batteries, so you’re ready to go right out of the box. The charging speed is super quick, and I love that it works for both AA and AAA in one compact unit.The smart charging feature gives me peace of mind knowing my batteries won’t overcharge, and the included batteries last a long time between charges. I’ve used them in remotes, toys, and gadgets, and they perform flawlessly.No more wasting money on disposables—this charger has already paid for itself. If you use batteries often, this is a must-have!

Great value. Charges fast! Easy to use.

I bought the Duracell ION SPEED 4000 Hi-Performance Charger (CEF27) mostly for home use, and it’s quickly become my go-to solution for keeping both AA and AAA batteries ready to go. It comes with 2 AA and 2 AAA NiMH batteries pre-charged, so you can use it straight out of the box—which is a nice touch.The charging time is very fast—I usually get my AA batteries to around 90% in a little over an hour, depending on their capacity. The charger works with any NiMH batteries, not just Duracell-branded ones, which adds flexibility if you already have rechargeables from other brands.There’s also a simple LED indicator that shows charging status, and the charger turns off automatically when charging is complete. I appreciate this both for safety and for preserving battery lifespan.The included batteries have been great so far—they hold their charge well and haven’t shown signs of capacity loss after multiple uses. According to the specs, they can be recharged up to 400 times, and if that holds up, this kit will easily pay for itself.Final verdict: If you want a dependable, quick charger with quality batteries included, this is a great option. It’s compact, efficient, and easy to use—a smart upgrade from slower, older chargers.

they can power my speedlite, it works perfectly, i've been using it for a while, still haven't charged them yetbut the performance until now is very satisfactory, it is in fact a good value for the money.PD: a good purchase as a photographer with budget flashes

Excellent , long lasting rechargable

This is my first time buying Duracell rechargeable batteries. I've been testing them for a while. They are very good, excellent quality. The charger is very fast, it charges all 4 in 2 hours, and it's simply an exceptional charger. Its batteries are of very good quality and perform very well.
