Battery Trays For Lithium Batteries

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

This lithium battery is very reliable.

Love cameras with extra battery power. Has 2 trays for batteries. Regular or rechargeable work. I have had it out now for a little over 3 months and it has taken pictures and videos and it is only a little over half way through the 1st tray of batteries. I love the fact that you can set it and sit back and enjoy the pictures coming in on your phone! Definitely recommended

I had origianlly been using 8 AAA bateries and they ran down quickly. This Lithium battery is definitely a upgrade to a handful of AAA batteries.

Coast’s lithium battery ZX450 all batteries that Coast supply are excellent. Reason I say this is because rechargeable lithium batteries sometimes have issues like premature failure. Things like not taking a charge, memory issues, and short run times to name a few. I do handle lion cells as recommended which is important for long life. Coast batteries and my lithium cellular batteries are the only batteries that work as promised regarding rechargeable lithium cells. I expect an a dramatic improvement with rechargeable lithium batteries of all sizes any time.

This Lithium battery pack is one of the smartest things I have ever heard of for batteries. It charges very fast for its size and lasts very long! I would recommend this item to others!

Need extra battery for my Canon R5,. I can always count on Watson lithium batteries for quality.

Finally a battery tester that will read NIMH batteries, along with Alkaline, Lithium and 9Volt. The pulse load gives a more accurate reading of what battery to use in a portable flash unit. Very easy to use and packs in easily when in the field.

I put two LP-E6NH Lithium Ion Batteries inside my battery grip and it lasted me well over a 8+ hour day of shooting! I am super happy with this purchase. Its a huge bonus in my eyes how light weight this is too. Great product and speedy shipping from B+H.

It's good to have a battery testing on hand and this one does the lithium and alkaline batteries. One thing I would note is for rechargeable batteries that have been handled a lot; it a good practice to clean terminals with  isopropyl alcohol otherwise it could give inconsistent results. This is covered in the manual and in their FAQ on the website. It is not readily apparent as to why you would need to read the manual for such a straight forward device :).
