DURACELLCEF27 ION SPEED 4000 Hi-Performance Charger, Includes 2 AA and 2 AAA NiMH Batteries

These batteries are great. The 2500 mah capacity and brand is why I chose these, and I'm definitely not disappointed. I usually buy eneloop pros, but these were almost half the price and have the same charging capacity. The only difference I saw was these duracell batteries are rated for up to 400 charging cycles versus the 500 charging cycles the eneloop pros are capable of. However, at this point in time, you can almost buy 8 of these duracell rechargeable AA batteries for the price of 4 AA eneloop pros. Nice.

Charge quickly and last as long as traditional batteries. Good product.

Does Exactly What It's Supposed ToNo complaints here—this product works exactly as expected. It arrived on time, in good condition, and performed its intended function without any issues. Reliable and as described. Would purchase again if needed.

Hate the price of regular batteries and they go in the garbage. These are more at first but well worth the price at the time and the small effort to recharge.

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.

I've had these for a little over 2 years now. I've recharged them hundreds if not thousands of times. Just the other day 2 decided to die out on me. 2 years of use is incredible in my opinion

Great deal, batteries with a charger, worked great. Would purchase again.

Dependable, long lasting, rechargeable. The only batteries I buy.
