I just ordered these and got the 4th gen!!!!
LSD= Low Self Discharge. Some companies call them "Pre-charged," but it's the same thing.
I've been a fan of rechargables since the 70's when my father had a bunch of GE Nicad cells which had capacity of perhaps 400 mAH. Nicads had so much more punch than alkaline batteries. For years and years I kept chasing the performance promise of higher capacity, 1200 mAH, 1400mAH, 1800mAH, 2100 mAH, 2300 mAH, 2500 mAH!!! 2650mAH!!!!!
Well, I ended up having all sorts of problems with the 2500 and 2650. It turns out that, besides a slightly larger diameter case which caused fit problems in some devices, they also had horrendous self- discharge. Easily half the charge was gone in a month, and in 2-3 months they were often dead.
After finding out about Eneloops (Sanyo Eneloop was the original LSD battery chemistry: Panasonic = Sanyo = Eneloop after Sanyo was bought out by Panasonic), I've phased over - perhaps 80% of my rechargeables are now LSD. The earlier LSD were 2000 mAH, as are these. These newer ones are good for 2100 cycles. Note that there is an alternate type of eneloop "XX" that give you 2500 mAH, but they are supposedly only good for 500 cycles. 500 cycles isn't bad though - even if you were to recharge them once a week you would still get 10 years...Read more ›
It's easy to spot the newest model purely because they are Panasonic branded
The cells are quoted as retaining up to 70% of their capacity for 5 years and are ready to use out of the box
I tested the pack I got and the capacities ranged from 2020-2078 mAh this can vary a bit but you're guaranteed a minimum of 1900 mAh. Unlike some other makers you can be sure you'll get the quoted capacity Despite the higher cost per battery the longevity of the Eneloop batteries has been very good I've had sets for a good while now (over 5 years) and they're still going strong where as some budget offerings have lost their capacity or worn out after a few years. I've also never had a problem with the Eneloop cells fitting, in the past a few makers have played around the standard AA size and some are a bit longer or larger in diameter this can cause problems on some devices fitting wise.
On the packaging Panasonic recommend using their own chargers, but I've never had a problem with a good quality third party smart/intelligent charger with any make of battery it's well worth investing in one of these as it can extend the life of cells and avoid overcharging problems that some timer/manual chargers have.Read more ›
I have been using Eneloops (along with Powerex, Imedion and Energizers) for about 5 years now and I have good things to say about Eneloops for the most part. I use them mainly for my speedlites (Canon 600RT, Canon EX580ii, YN600RT, YNE3RT and so on) but you can use them for anything that uses an AA battery. These are NiMH which means they do have a discharge over time so my advice is to use these in places where there is a larger power consumption and needs recharge more frequently like in my case an external flash. You would probably not want to use it at places like a regular wall clock.
They have always performed quite well over the years although they do tend to develop "memory" in which you would need to fully discharge them once in a while and then have them fully charge.
Over the years, I have gathered around 7 sets (each set = 4 batteries) of Eneloops. I usually use my Maha chargers to discharge and charge them. I recently got a EBL charger that I will be testing out to see how well it works.
The name in this Amazon listing claims "2100mAh" but yet the actual packaging states "2000mAh" and the battery itself claims "1900mAh." So quite honestly, I do not know which is the most accurate of the three. It could very well be a marketing move to lured potential buyers.
They seem to hold their charge very well but when you do notice that the batteries are not doing so, that would usually mean you would need to discharge them first.
My tips for managing these sets of batteries is to label each set accordingly so when I charge them, I usually keep them charging in the same charger.Read more ›
