Rechargeable D Cell LR20 Batteries 4 Pack

Well, this is different. Heads up fisher men...the Valkate DD recharge lithium batteries is a must have to power those aerators for live bait fans! And the weight of these batteries are outstanding! Huge difference between the regular DD batteries! If you fish as much as I do...then these are a must have!

Good batteries

I was using a different brand that wasn't lasting long in my back motion light. I've been using alkaline batteries in that light for years, and they were lasting a long time. I use rechargeable lithium AA batteries in my security cameras, and they work great. Last pretty long. So, I started using rechargeable D batteries from the same company the AAs come from. The Ds were not working as advertised. So, VOLKATE was the next option up. First off - I do like the USB charging. WAY more convenient and quicker than my charger. Next - these do NOT last long in colder weather. The product says -4F - that is FALSE. These don't last more than a couple days out in <30F - and this is a motion light that doesn't go off unless there's movement. My dogs aren't out long in colder weather. They do their business then come back in. These lights go on when the dogs go out the door, but goes back off when the dogs are out toward the back of the fence doing their thing. Then back on again when they come inside. No other movement out there the rest of the night. I had to pull these out every couple of days to recharge. Warmer weather is here, so we'll see how it goes. So far, they've been in my light for several days and it's been 50F or above. So, that's better than it was this past winter. Hope they aren't a waste of my money

Sorry to say not good . 2 out of the 4 I bought did not work. I wish I could return but can't. I all so bought AAA and the same thing 1 did not work and one stoped working. Do not buy.

Got these to run RV refrigerator air circulation fan. They charged fast and lasted long. Will update in time if this changes but so far so good.

Light, easy to charge, long lasting

These rechargeable D batteries are a convenient and cost-effective option for powering larger devices. The two-pack is great for items that require D-size batteries, such as flashlights, toys, and other household electronics. They can be recharged multiple times, helping reduce the need for disposable batteries and saving money over time. The batteries provide reliable performance and are easy to recharge when needed. Overall, they are a practical choice for anyone looking for reusable, long-lasting power for everyday devices.

At 7500 mah, these d cells have around half the capacity of alkaline cells. That said, they have a lower self discharge rate and a convenient usb c connector for charging. Another plus is that they don’t have a high propensity for leakage so they’re excellent in storage. I use them to power an old Maglite which I keep in a cabinet along with an emergency radio and various other paraphernalia as an emergency kit, preparation for storms that I hope will never come.

Recargas en 30 min y de nuevo a usarse, duran1 mes, en este caso ocupandose para el boiler.

These work really well, I look forward to saving some money instead of buying disposable batteries. They charge decently fast and take the normal USBC cables. I use them in a portable minnow tank aerator.

Llego en excelentes condiciones, Son recargables y funcionaron muy bien

These worked great! Had a fan/light for tent camping for 2 weeks. Charged well with solar panel. Lasted running fan in tent most of the night.

UPDATE*** Bought these for my watch winder and they work great. So easy to use and charge I don't even have to remove them to charge them. 5/5 star item buy with confidence
