Lithium Rechargeable D Batteries 4 Pack With Charger

Good rechargeable batteries and charger.

This thing is AWESOME! I bought a pack of 16 Panasonic Eneloop rechargeable batteries and this thing is GREAT for when I get home from a shoot and offload the batteries from my flashes and dump 8 of them in the charger at a time. It takes me roughly 2.5 hours to charge 8 dead batteries. I haven't had a need to try the car charger yet, but either way I'm a fan.

This Panasonic Eneloop Power Pack Kit is the very best rechargeable battery and charger kit I’ve ever owned. The Eneloop batteries are by far the best rechargeables I’ve ever bought. I especially like the fact that they hold a charge even in storage for a VERY long period of time. I highly recommend this power pack kit to anyone looking for high quality rechargeable batteries and compatible charger.

I already had two of the Nikon EN-EL15c Rechargeable Lithium-Ion Batteries, but I recently purchased the Nikon MB-N11 Power Battery Pack with Vertical Grip for my Z7ii which takes two of the EN-EL15c batteries, so having a spare made sense to me. I also own several EN-EL15 batteries for my D850 and have experience zero problems with Nikon batteries.

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.

Love that I was able to purchase the rechargeable batteries with the charger. It was easy to use.

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.

I purchased this, not for analyzing rechargeable batteries, but for measuring capacity of several different brands of lithium AA batteries. There is a common knockoff of this product that didn't actually work for my use case, but I did use it for charging batteries, and I can say that the user interface of the Powerex is much more intuitive and easier to use. As far as customer service, I emailed Powerex to find out if this would do what I was trying to do, and a representative called me and let me know that while it is not an officially supported use, it would work, which proved to be true. I would definitely buy more products from them after having that experience.

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.

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