What is the difference between the Panasonic K-KJ17KHCA4A Eneloop Pro vs the Panasonic K-KJ17MCA4BA? Which is a better choice to buy?

The pro cells hold about 25% more capacity under use before you have to charge it. That translates to longer run times for things like hiking GPS and high powered flashlights and wireless microphones in constant use. The trade off is that the pro cells don't retain a charge when stored which is good if you normally plan to drain the battery within a few days of charging it. In a TV or DVD remote control, the pro cells would have to be charged at least once every several months, where the regular cells will last for years without charging in remote controls that are not used daily. So far, I have never had an Eneloop battery ever leak, where I have had several expensive remote controls and headlamp LED's destroyed by leaking modern alkaline batteries. Modern alkaline batteries will often start leaking while still performing and still many years before the best used date has arrived. Modern warrantees for alkaline batteries only cover the battery that fails to perform, not the expensive device that was destroyed by the leaking alkaline battery. I have had several Duracell batteries start leaking while still unused in the original package stored in a cool dry place (basement) and still have a few years before the best used date has arrived. Today's alkaline batteries are junk. The standard Eneloop battery seems to be the most dependable battery I have ever found. They cost more, but the extra cost is worth it. Other brands of NiMH batteries I use often don't hold a charge in storage. The supposed lower voltage compared to alkaline is not the whole truth. Under extreme low power loads, alkaline battery voltage is higher, but under higher loads like cameras and flashlights, the alkaline battery voltage drops lower than NiMH battery within a second of the time the load is applied and then goes back up to resting voltage after the load is turned off. After an alkaline battery looses around 20% of its original charge, it is performing worse than a rechargeable NiMH battery and many devices like cameras can't take that drop in voltage.

i just received the charger and i do not see any indicator lights on mine. anybody???

Just to update this - the chargers shipping now have hidden lights (unlike the product picture). To see them charger must be plugged in with batteries in place. NOTE: To clarify the paper comment - the batteries are shipped in the charger in the charging position. Before first use, remove all four batteries and you will find a small piece of cardboard paper at the top covering the positive charging contacts. This paper is to be discarded. Put the batteries back in position, plug in charger to working circuit and you will then see the now hidden lights under the white plastic "skin" below each battery. This is still true as of 11/2018.

Do the Eneloop batteries require an Eneloop charger or can they be charged in other AA and AAA battery chargers?

The Sanyo/Panasonic eneloop cells can be recharged in any good-quality charger designed for NiMH batteries.For best battery lifespan, choose a 'smart' charger that has a charge time between 2 and 5 hours.Avoid slow, timer-based dumb charger that will over-charge your batteries, and 'ultra-fast' 30-minute chargers that will over-heat your batteries.

Must you charge 4 batteries at a time OR can you charge, say 2 with 2 open slots?

The Panasonic BQ-CC17 can recharge 1, 2, 3 or 4 AA/AAA cells at once. You don't need to charge in pairs like in the case of old MQN06 charger.

If you're tired of your gadgets constantly running out of juice, like some people I know running out of excuses, these Panasonic eneloops are the answer. Look, I gave EBL a shot. They were fine—nothing special. Like that one friend who shows up to every party with store-bought chips. But these? These are the real deal. They hold charge, last longer, and actually make you feel like your money wasn’t a waste. Solid performance, zero regrets. So, yeah, save yourself the trouble, grab these instead of the wannabes. They’ll outlast whatever other junk you throw at them.

Exactly what I need. Much better on money to recharge those than buying new batteries all the time, unless you need them for a remote - which can hold regular batteries for years. But for a flashlight or any other device, those are perfect. Charge fast and last way longer than regular batteries. Will get also the AAA 24 package!

These are good rechargeable batteries -- seem to hold their pre-charge pretty well, and then seem to recharge fairly quickly using an original OEM charger (mine is a Sanyo, the original manufacturer of Eneloop batteries). Only limitation is that they are quite expensive for what they are; time will tell as to their overall value depending on how well they perform after many, many charge cycles.

Sep 9, 2019 was when I last bought this box, that's almost exactly 5 years ago, short of a few days. I had split the box of 24 with another friend and regularly rotate through the 12 that I have to power wireless mice and an xbox controller. On the day of this review, the first of the 12 batteries had the Panasonic charger flashing green on it - indicating that the battery has gone bad. That's 5 years of amazing usage among its brothers. It was given a proper funeral and sent to battery recycling. Meanwhile the remaining batteries, while starting to show their age by not lasting as long as they used to, still continue to chug along getting me through a week's heavy controller gaming. I highly recommend these batteries!
