Lithium Battery Not Charging To 100

It works wonderfully charging the lithium battery included for my A6500.  Does exactly what it is supposed to do.  What else can you say.

This lithium battery is very reliable.

if you use a dr-100 for field recording, you know that the lithium battery (bpl-2) does not last too long if phantom power is needed. i have 2 batteries and i run out of power every time. when this external battery came out, i bought it very fast to try it. for my surprise it works amazingly good. highly recommended. i use 6 duracell 2450 mah on it and it lasts for many, many hours using the phantom power on my dr-100. cheers

Bought this battery as a spare battery for my RX 100. I didn't want to worry about re-charging the in-camera battery. I would just swap out and replace with my spare.

After ~5.5yrs, I noticed the internal cooling-fan began running full-time (quiet, but usually only runs if the batteries require charging, such as after an outage), and the usually-cool lower vents of the UPS were now a bit warm due to active charging circuitry. Then the normally 100% charge-level LCD indicator at times showed only 80% despite no outage. Time for a new battery pack! The most involved part was shutting down & disconnecting & eventually reconnecting all the protected equipment. After all was disconnected, out of curiosity I turned the UPS off & then back on - the charge-level indicator dropped from 100% to 60%! The old battery pack was in worse shape than I thought. Replacing the pack involved removing a couple screws at the bottom of the UPS & then sliding the face-plate down, then out. Then disconnect the power connector from the old pack, slide the old pack out, new pack in, reconnect the power connector & reattach the face-plate. Simple & quick! The charge level indicated 100% as soon as I turned the UPS back on - I let it charge for the recommended time anyway although I don't think that was necessary in my case because there was never any indication it was charging: the fan was off again & the lower vents cool to the touch again. My UPS seems to have a separate minor issue - a poorly connected LED that is supposed to illuminate the Power Button when the UPS is turned on. Instead, on mine, sometimes it's lit, sometimes it flickers, but usually it's off. The new battery pack didn't change that - the caution being that if the UPS has a more significant dysfunction, replacing the battery pack could be an expensive way to find out the issue isn't the battery pack. One last comment: Unlike APC, CyberPower unfortunately doesn't seem to have a recycling program for their spent battery packs.

I needed to get basic power for lights into a shed that had no electrical hookup available. I have tried many battery powered lights, that just didn't cut it. They would die or were just not bright enough. I decided to try a Delta 2 and 2-100 watt solar panels to recharge the battery. I was only able to mount the panels on the east slope of the roof, but it has held the charge. I am in Ohio where it gets too cold and keeps the battery from charging when it gets too cold, so we have had several days where we weren't charging because the shed was too cold. I still have not run out of power for the 100' ten light strand I hung up. This setup is an expensive fix, but it has proved itself to work even through our cold, gray Ohio winter.

This manual flash has everything I need and especially like the lithium battery. just bought a second unit.

Long lasting Lithium battery makes it cost effective.

Lithium without the need to recharge. Excellent long-life battery.

I bought one, have to buy another, great sony lithium battery.
