" ...  I buy coupe sets of these battery's for to be able to use them in my mBot Ranger as they have more power than usual non rechargeable cheep battery's.  ...  "

" ...  True aa battery performance why did it take so many years to make a rechargible bat with the same output.  ...  "
comment
" ...  These batteries took between only one to two hours to fully charge and are working fine so far. ... I can't vouch for battery life and durability at this time, but regular batteries keep my lights coming on for almost a month. ... Even if these didn't go that long, the short charging time and not needing to buy more batteries is a real plus.  ...  "

" ...  I like the idea of rechargeable batteries as if I have to change batteries every few months, as opposed to the two years on ideal settings that Blink claims, then I won't feel so bad about it. ... What I also like about these is that you don't need a proprietary cradle in which to charge. ... They even feature their own LED which'll glow red for charging and green for ready in under two hours (as opposed to the six hours or more I had to wait when I was a kid in the '80's .  ...  "

" ...  Here are my thoughts on these batteries: ... The battery seems sturdy and in one piece. ... Weight: Since lithium-based batteries have higher energy densities, the battery is significantly lighter when compared to a 2,400mAh LSD NiMH. ... Compared to an LSD NiMH cell, voltage drops on these batteries are steeper in the short term, however, these cells can provide approximately the same voltage until the whole cell is depleted (i.e. ... Because the voltage stays constant throughout the whole discharge cycle, it is not possible to gauge battery capacity based on the terminal voltage (it will always read around 1.51-1.53V when measured without load, or 0V when depleted). ... This should not be a problem if the batteries are actively being used and recharged, although letting the batteries sit idle without being charged for 3 or more years may result in irreversible cell damage (I assume that's why the manufacturer stated that the service life is 3 years). ... Overall, these batteries are great. ... Although they are much more expensive than other batteries out there, they serve my purposes quite well and I am very happy with them.  ...  "

" ...  They quickly recharge using any USB charger.  ...  "

" ...  Style/Design: These look exactly like your traditional AA batteries, with the exception that there is a built-in micro USB port on top of each battery (as opposed to other designs that have this on the side). ... There is also a charging indicator light that turns red when the battery is being charged and turns off when the charging is complete. ... The enclosed 4-in-1 cable is quite handy so you can simply use one cable to charge 4 batteries at once without having to use a USB hub or 4 separate cables. ... Charging Test: Charging these batteries using my battery pack, which outputs a USB voltage of around 5.3V, the charging process took 1h 55m. ... This was quite on point with quoted 2h timeframe from the manufacturer (the charging time may be closer to 2h exactly for USB power sources that are lower than 5.3V, although the difference would most likely be nominal). ... This should not be a problem if the batteries are actively being used and recharged, although letting the batteries sit idle without being charged for 3 or more years may result in irreversible cell damage (I assume that's why the manufacturer stated that the service life is 3 years).  ...  "

" ...  The packaging is well done, there was a case for the batteries and the charging cable seems sturdy. ... Fortunately, these have a BMS to handle nearly any charger that is close to specification.  ...  "

" ...  Most of us have access to USB charging because of our phones and having a battery that uses it is extremely convenient. ...

" ...  I decided to try the Blacklube batteries because I was fascinated by the ability to recharge them via USB which I had not seen before. ... I was able to charge them up with the supplied USB cord and they all showed the red light indicating recharging. ... When the were fully charged they all showed the green light indicating ready to use. ... No more guessing whether the batteries are all fully charged or charged the same.  ...  "
