1.5V Rechargeable D Batteries with USB-C Charging Cable | Long-Lasting Lithium D Cell Batteries for Flashlights, Toys, Radios & More | LR20 Replacement Battery (4 Pack)

You know you have first world problems when you're concern for the day is getting good enough batteries for the automatic opening garbage can. So when I tell you I put these in the garbage, that's a good thing. They work well and with a brief charge seem to last a long time opening my garbage can. Highly recommended.

This item was as advertised and it wasn't damaged when it arrived and worked well but the batteries are alittle lite for D size but okay.

Good for the price !!!

Less than a year ago, I bought 2 packs of 8 D cells for my emergency lantern for if the power goes out. The batteries were all corroded in the package, AGAIN, so I looked for rechargeables and found these with built in USB chargers. My Dad would have loved these! They blink while charging and the LED's become solid when they're charged. They charge pretty quickly. I wanted to see how long the charge would last, so I put them in the lantern and turned it up all the way, which is seriously bright and when the power goes out, I only turn it up less than half way. Two hours later, the lantern was still just as bright and the batteries tested in the green. I read some reviews which said that the batteries emit signals which interfere with radios, so I put them into my short wave radio and it worked fine and I tried them on AM radio, which the slightest little thing will interfere with, and that also worked fine. These are ingenious.

These 4 batteries work 10% as long as ni cad D cell batteries. That's 2 hours before going dead. It says Long-lasting Lithium D Cell batteries. This is purely false advertising and wrong.

10/10 saved my life (and my bank account) during the newborn phase, since all my baby wanted was to be in her swing! 10/10 recommend to every parent, or just everyone in general, I will be going and buying multiple rechargeable batteries is all different types!

I purchased these for my 3 cell D battery maglite and they are truly beyond surprising with how lite wieght they are which leads to less strain from the typical battery used a 3 D cell maglite. They charge fast and last long even though they literally blow my mind at how they literally have like zero wieght compared too any other regular D cell battery. I recommend them as they have a worked great for me so far.

These batteries can put out potentially dangerous amounts of current - I measured 4.5A with a terminal voltage of 1V which could melt wires and potentially start a fire. Otherwise, these mostly live up to expectations - I measured 3200mA/hr not the claimed 3700.
