High Quality 18650 Lithium Ion Battery

[Canon BP-828] Watson BP-828 Lithium-Ion Battery is good quality battery, work very good...

[3.7 V] Nitecore 18650 Li-Ion Rechargeable Battery is a great source of stored energy. Being rechargeable makes this battery cost effective. This Nitecore Li-Ion battery has demonstrated its dependability in a flashlight over a period of seven hours of intermittent use. Great product!

[750 VA] [This review was collected as part of a promotion.] I’ve had this running for a couple weeks now and couldn’t be happier. I’ve installed this quite easily in my wall rack and have to say I am very happy with it’s performance and solid build quality. It’s as plug and play as you’re going to get. I find myself often looking over to see that it running as it’s very quiet and the fan only turns on when the load get’s to a certain levelEven then I just don’t hear it. Seems to be very efficient with low heat. This unit also has the lithium-ion battery and seems to weigh less than half the weight (just over 30lbs) of my older lead acid battery unit and smaller in overall size. In the long run I feel it’s going to be much more cost effective replacing the lithium-ion battery over time as they’re just getting cheaper and last longer than the older lead acid batteries. From an aesthetics point of view, I feel the unit is nicely designed and appealing. The multi-function LCD is easy to use and view various in-depth metrics. If you’re in the market looking for a smart ups or to replace a older lead acid unit then I highly recommend the APC smart-ups. Good quality brand and dependability.

[0.155 lb] Rechargeable lithium-ion battery used for Olympus camera works well everytime.

[11.1 VDC] I use this battery as a back-up to my Nikon battery EN-EL4a rechargeable Lithium-ion Battery Pack. I always use my original Nikon battery but if I am out in the field and my Nikon battery goes down after many shots, I then switch to the the Watson EN-EL4A Lithium-Ion Battery Pack as my back-up until I can re-charge the Nikon battery again at home. I find it's more economical using it that way since there is such a big price difference between the Nikon Battery and the Watson Battery. However the Watson battery is a very good battery and reliable in every way.

[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

[0.16 lb] I bought the EN-EL 14A Lithium-Ion battery for use in BG-N12 Battery Grip for use during a once-in-a-lifetime photo expedition to Maui, Hawaii. The battery held its charge.

[0.1 lb] 18650-type lithium rechargeable batteries are very popular for high-powered LED flashlights. These batteries have a high energy content (up to 13 watt-hours) and are capable of high peak current discharge (up to 40 amps); they should not be stored loosely such that an accidental short-circuit could occur! This carrier is made of very tough, flexible rubber, about 2 mm thick. It securely holds the batteries and protects the battery contacts. Unlike a tray-type carrier, this carrier allows single cells to be removed or inserted without allowing the other cells to become loose. You can carry extra batteries in your toolkit or range bag without fear.
