eneloop pro

I own a Sony U60 MP3 player that is great for recording and I use it often when out as I do not carry a smartphone out sometimes. It has ONE TOUCH record even from power off state. Excellent device despite its storage capacity, with only one flaw. These use a single AAA battery. Clearly these use a DC-DC converter to boost the 1.5V to something else say 5V. Leaves very little wiggle room for voltage drops. But rechargeable naturally have a lower voltage. Normal Eneloops barely lasted two hours in the player and when 'drained' in there still had a bit of use in a walkman before being fully actually drained. Normal Eneloops I have used extensively with very little issue in serious gear like A WM-D6C walkman, but due to the lower operating voltage and faster drain under high current load, it just wouldn't work for very long in this device. It is the FIRST time normal eneloops have failed me, as did other rechargables tested. I ended up using some Energizer ultimate lithiums in the player, getting 5 to 6 days of daily intensive use from a single battery, lasted an entire trip and i came home with capacity to spare. Helps those stay at 1.5V until the end of the discharge curve, so less current (Amps) needed due to the higher voltage. Normal Eneloops therefore prompt a battery change even in a single listening session. Not a flaw of the batteries, but the device by nature needing every millivolt from its 1.5V AAA battery. I reasoned that the Eneloop pros have thinner plates with more surface area and thus will provide more current and likely less voltage drop under load as this is what they are designed for. Would they work where all other rechargables failed? They did. They run the player for roughly 1.5 days of usage of 6 to 8 hours of play. Not as good as the Energizer Lithiums 30 or so hours (higher voltage meant less current draw), but I can use it for a day (or far longer in standby as it draws barely anything), put an Eneloop pro off the smart charger and take the second one to continue use. They perform flawlessly with this device. And it also works that I am not depleting the Eneloop Pros to 100 DoD, so using the Eneloop smart charger will protect the life of these. WARNING ADVICE: I WOULD NOT USE THEM WITHOUT A SMART CHARGER. A DUMB CHARGER WILL DESTROY THESE BATTERIES FAST DUE TO THE THINNER PLATES IF IT OVERCHARGES THEM! Normal Eneloops are far more rugged in this regard. I do not like using primary batteries due to the environment, unless i was going to be on a long off grid trip where the lithiums would make sense. I always bought and for most devices if they work well and the extra capacity is not needed Normal Eneloops as they are far more hardy, thicker plates and can last upwards of a decade of heavy cycling and low self-discharge. But when you need that higher operating voltage under load and ability to handle higher current draw, this battery solved an edge-case of a device that did not like most NiMH rechargables as the extra voltage under load and slightly higher capacity combined to make it a superb battery for this purpose. The interesting sidenote was the battery gauge, designed for alkaline batteries actually was close to accurate. Three bars for an hour or so, two bars for most then 1 bar with still enough juice for say 30 to 45 minutes of play. So its discharge curve in such a device will still give ample warning of requiring a battery change and not a sudden voltage collapse as the energizer lithiums will do in this use-case. In devices that only use a single AAA battery or in devices that need the highest possible voltage from your batteries under load (or if you need more capacity and do not mind 500 cycles over 2000+) use these. I personally would only use these in those power scenarios as I will always usually choose more cycles unless I need something like this. They most certainly got the job done. Update: I bought four more AAs, had them in a walkman for a year then used in a Honeywell portable fan, and it ran the fan for 7:30 to 8 hours non-stop during the heatwave (I wanted the longest possible runtime). They don't self discharge fast, and have worked to keep the fan on standby. They have not deteriorated from being discharged until the fan stops (about 1.1 volts) and recharged daily during the hot spring and they were already a year old by this point having been used a few times in a D6C Walkman. I bought yet another pack of AAAs also, these do really perform and are worth the price tag. I use the Eneloop smart charger (USB) and these are the only chargers we should be using! There is only one flaw of Eneloop Pros, in that they seem to get very hot while charging in the official smart charger if you close the plastic lid. Hotter than other comparable rechargeables. I eventually started blowing a little fan on them to cool them down while charging and keep the lid open. Despite this, they are still giving their as new capacity a year on.

Best rechargeable batteries according to the experts & originally charged with renewable energy to boot

I have bought several packs, usually one or two in each promotion. The charger had been used for over 6 years and still works well. AAA is needed in remote control, alarm clock, etc, and AA in many small devices such as LED lamp, . This one is long lasting. I am not quite sure if it is cheaper to use one-time battery in the long run but it is good for me not needing to dispose used battery. By the way, in the long run AA/AAA battery-operated items are more effective for emergency use than chargeable one with embedded lithium battery. I got a power cut and found that the chargeable LED light was useless once used up and it took time to recharge it even I had a power bank.

These are really good batteries

they are what they are great value last a long while well worth the money

I’ve been using Eneloop Pro rechargeable batteries for about ten years now, and they’ve never let me down. Every time I buy them again, they fully live up to my expectations. They’re reliable, long-lasting, and have never disappointed me. Absolutely recommended for anyone who needs dependable rechargeable batteries.

I only use eneloop pro batteries. The best rechargeable there is in my opinion.

Really good for high drain devices
