Panasonic BK-3HCCA4BA eneloop pro AA High-Capacity Ni-MH Pre-Charged Rechargeable Batteries, 4-Battery Pack

[Note: [This is an updated version of my original "Sanyo eneloop FAQ," which was first published in May 2012]br>br>I've been using eneloop low-voltage for quite some time now. self- I've been using NiMH batteries since the beginning of 2007, and I'm very happy with them. One thing I've noticed is that newcomers to the world of rechargeable batteries frequently have the same questions and concerns about eneloop. So, here's my list of frequently asked questions about eneloop. This is a work-in-progress list. br>br>[Q1] Why are there so many different eneloop batteries with different capacities and cycle times? What are the numbers in your life? br>[A] Eneloop batteries can be divided into three groups:
- Version standard: The original Sanyo eneloop (circa 2006) had a capacity of 2000mAh for AA batteries (800mAh for AAA) and 1000mAh for AAA batteries. the duration of a cycle Longer lifespans are advertised in subsequent generations (1500/1800/2100). at the same time (cycles) The charge retention rates have consistently increased from "85% after 1 year" to "90% after 1 year" after 1 year" after 1 year" after 1 year" after 1 year" after 1 year%2 (Refer to my uploaded photo on how to identify different generations of eneloop cells)
- 70% after 5 years"
- High- Version with capacity: The Sanyo XX (circa 2010) had a capacity of 2500mAh but only 500 cycles. The demand- After 1 year", the retention rate is slightly lower at "75% than before 1 year". The capacity of the newer Panasonic eneloop PRO was increased to 2550mAh, and it now has a charge-and-play feature. after one year", retention rate to "85% after one year", retention rate to "85%%
- Version LITE: These have half the capacity of standard eneloop but twice the cycle life; however, they are not sold in the United States. br>br>[Q2] Do Panasonic eneloop cells perform better than Sanyo eneloop cells of previous generations? br>[A] On paper, the newer generation has a longer cycle life and a lower self-discharge rate. the volume of discharge However, because they all have the same capacity, you won't notice any differences in practice. After about ten years, if at all, the difference in charge retention rate and cycle life may become apparent. br>br>[Q3] Does the PRO version of eneloop cells differ physically from the standard version? br>[A] The PRO cells are slightly thicker, measuring 14 mm in diameter. 4 mm (verses 14 and 15). 1mm). As a result, if the battery compartment in your appliance is too small, they may not fit. fitting. br>br>[Q4] What is the distinction between 'Pre-' and 'Post-'? 'Charged,' 'Hybrid,' and 'Stay-Alive' are some of the terms used. 'Charged,' 'Active Charged,' 'Ready to Use,' and 'Ready to Go,' respectively? br>[A] All of these are marketing terms for Low-Income Housing. Self- NiMH batteries with a low self-discharge rate (LSD). The term 'Pre-' was coined by Sanyo for the first time. In 2006, I was charged with Sanyo eneloop. On each cell of the most recent Panasonic eneloop, it says "Ready to use. " br>br>[Q5] I've seen a lot of other rechargeable battery brands advertised as Pre-charged. Charged. Are they comparable to Panasonic's eneloop? br>[A] No, in most cases. In terms of charge retention rate and cycle life, the Sanyo/Panasonic eneloop is still the best. Similar to eneloop, other brands claim to have a low self-discharge rate and a long cycle life. However, none of them, in my experience, actually work. br>br>[Q6] Can you tell me about the AmazonBasics Pre- Rechargeable Batteries That Have Been Fully Charged br>[A] To be clear, AmazonBasic rechargeable NiMH batteries come in three different versions:
- The first version.

The Eneloop Pro AA is still a great choice for high-output flashlights and other high-demand devices, but there are a few caveats. Although Pro has a larger overall capacity, it is still important to understand the differences before purchasing. br>br>First and foremost, the Pro version has a lifespan of only about 500 charging cycles compared to over 2000 for the white Eneloop batteries. However, considering that you could charge them twice a week and get about 5 years out of them, this is still a good amount of longevity. Next, Eneloop Pro has a higher self-discharge rate. Panasonic claims that a fully charged battery will be depleted to 85% after a year, compared to 90% with a regular AA Eneloop. Although there isn't much of a difference, it's worth noting. I've heard that the white Eneloops are more tolerant of overcharging and other mistreatment, but I try to look after them to avoid performance issues. br>br>Now for the good news: the AA capacity has been increased to 2500 mAh, up from 2000 in the previous version. This, of course, means that devices will last longer. For example if you have an item that runs for 60 minutes with a white Eneloop, roughly you could expect a 75 minute run time with an Eneloop Pro or approximately The Pro is a good investment if you think it's worth it, especially considering the shorter lifespan. If overall durability is more important, the white Eneloop is the way to go. br>br>I use my AA Eneloop Pros primarily in some of my flashlights because I spend a lot of time camping, volunteering with my son's boy scout troop, and other nighttime activities, so I need as much run time as possible from my lights and this is a cost-effective way to get it. They don't leak like alkaline batteries and are much less expensive in the long run, though I do occasionally use Energizer Lithium AAs when Eneloops and a charger aren't possible to bring. br>br>In my 4x AA Fenix flashlight, I've tested a variety of batteries, and alkalines are the worst performers, lasting about an hour and 49 minutes on the high setting. The standard white Eneloops have a duration of 2 hours and 33 minutes. I now get 3 hours and 24 minutes with the Eneloop Pro - Another hour and a half. The Energizer Lithium AAs are the best of the bunch in terms of performance, lasting the longest at 4 hours and 42 minutes. The disadvantage is that they are expensive and disposable, but they are still a good option when you need stable batteries with long run times and good performance. Eneloop Pro, on the other hand, aren't slouches, boasting 500 life cycles. br>br>If you're familiar with cell differences, the Pro is a must-have for demanding devices. However, it's probably best to keep both types of Eneloops on hand for everyday use and save the Pro for the most draining items.

Eneloop has been my go-to controller for my computer and Xbox for years. They've never given me any problems, and they last longer than any other AA I've tried. They ALL arrived at 43% which is not charged but that is fine. However, 2 of them arrived perfectly, charged to 100% on my golisi S4 smart charger, but the other two WILL NOT CHARGE 49% CAPACITY AT ALL. I've tried a number of different chargers, and they're all bad. Will return them and request replacements. br>br> br>br>MAKE SURE THESE BATTERIES ARE TESTED! THE COST OF A GOOD CHARGER IS ONLY $20. 30$ AND I'VE HAD THIS ONE FOR YEARS, IT SHOWES EVERYTHING THERE IS TO KNOW ABOUT THE BATTERIES, AND WITHOUT IT, I WOULD HAVE PROBABLY NOT KNOWN UNTIL THE RETURN PERIOD HAD PASSED! br>br>Everyone, without exception, requires a good charger to use with good batteries.

During quarantine 2020, I began to spend a lot of time playing video games. That first month, I threw away about 2 1/2 tons of AA batteries before realizing it was ridiculous and wrong, so I bought two pairs of these for my controller. They're fine; I can eat two in about three days if I'm a total couch potato, and they're a little less expensive than name brand disposable AA's. I've noticed that one of the four drains more quickly than the others, and I have a fancy charger to prove it. Overall, they're dependable, and you don't need to go through a lot of disposable batteries to justify the cost of rechargeable batteries and a good charger.
