Lithium Ion D Cell Batteries

[0.25 lb] Like the ability to change 2 batteries at the same time and keep them together. Thinking about getting another for my other two Lithium Ion batteries.

[0.195 lb] Lithium Ion batteries are notoriously mislabeled for capacity. I use these for camera stabilizers and flashlights, and expect performance. This Nitecore battery provides the full labeled current with minimal voltage drop. I have cycled one of my three four times, and performance was fully maintained. The only issue was with my chargers - the batteries would show fast charging, but never quite finish. Removing the battery and reinserting showed a fully charged battery, suggesting an issue with both chargers. Performance is very good.

[Black] 50W is very loud! Lightweight Lithium Ion rechargeable batteries. Very easy to use. I especially like the 10 second built-in memory.

[0.115 lb] I do not like spare lithium Ion batteries floating around in a case or bag. And why Profoto does not provide a custom pouch for their batteries is quizzical. After reviewing many of the third-party pouches available, these LensCoat BatteryPouches fit the bill. A lengthy video chat with a patient and very helpful B&H CSR was critical in finding the right product! Thank you Dave!

[1.93 lb] These batteries can be used for different pieces of equipment that take the NP-F 6600mAh lithium-ion batteries and the charger it comes with is extremely compact and works great.

[0.025 lb] This is my first time purchasing rechargeable Lithium Ion batteries with a built-in USB charging port. That's a very convenient way to charge the battery especially if you forgot the adapter at home.

[450 nm] This light is compact, very bright, and uses common AAA batteries instead of the more costly lithium ion rechargables. Overall a great little light for use around my shop. The only thing I don't know yet is how long the LED will last. However as a guide, I have had a 4 DCell LED Maglight for around five years and it's still going stong.

[Audio-for-Video] I use this unit in the field for recording birds. It runs for hours and hours on Lithium Ion batteries. It's light, easy to use, and had great features, like locking XLR inputs, single folder storage of recordings, and it's 32 bit float.

[1.33 lb] As stated in the headline, it works, charges slower so the lithium-ion batteries last longer. I have the fast charger but bought this to condition the batteries over time. Fast charging all the time will shorten the life of your $$ battery.

[0.1 lb] I purchased the 3400 mAh Rechargeable Lithium-Ion Battery for my LEDlenser ML6 Lantern so that I would have a spare. The lantern comes with a stock 3000 mAh OEM battery. Using a battery analyzer made for testing of Lithium Ion 18650 batteries, I placed both batteries side by side. I ran four tests that Charged/Discharged and Charged again. I wanted to both exercise the new batteries, as well as compare their performance 3000 mAh vs 3400 mAh. Surprisingly the 3000 mAh battery out performed the 3400 mAh battery by a great deal. This was disappointing to have purchased a top notch battery so I would have extra capacity for my ML6 Lantern. Perhaps the company should question their supplier. The 3400 mAh battery was left in the dust. 3000 mAh LEDlenser Battery 3400 mAh LEDlenser Battery Test #1 3263 mAh 3137 mAh Test #2 3269 mAh 3176 mAh Test #3 3357 mAh 3178 mAh Test #4 3316 mAh 3179 mAh
