2 Pack Rechargeable Lithium D Cell Batteries with USB 4 in 1 Charging Cable,1.5V LR20 D Size Battery Replacement for Toys

These things are lightweight they weigh next to nothing I honestly thought they weren't going to work worth the s*** or hold a charge but these things last way longer than Duracell and they recharge I have yet to have to really put any of them on a charger and they come with a really cool four-pronged c charger for so you can charge all four of them at one time very happy with this product I have now bought in the c battery to match this I think you guys are doing great keep up the good job

This battery only weighs 46 grams as compared to the regular lead zink "D" which weighs 143It can be easily charged.I think it is easily worth the price.Now, this is a low amp application and I somehow doubt it would be as impressive in something under load

OK, the negatives are what others have said: they are likely an underpowered battery inside a D sleeve. Yep.HOWEVER, if you are a person that RARELY uses D batteries, then this is a good product.Right now, the ONLY thing that I have that uses a D battery is a siphon pump. I needed a siphon pump because I have a few older gasoline-powered cars that are rarely driven. And if the gas gets older, I would rather siphon it out rather than try to burn it out by running the engine.The battery-operated siphon that I purchased can take two D cells or 6 AA cells. If I purchased batteries for this siphon pump, they would likely be dead the next time I want to use them. And we all know that disappointment.As a result, for me, THESE rechargeable batteries make sense. I was able to pull 10 gallons out of the 1969 'vette without any loss of power. Likely I will be able to use it to put gas into a boat as well.Still, they would be a bargain at half the price... but this seems to be one of the lowest prices for 4 D cells and a charging cable.

These batteries are easy to recharge and quick. The best part is no more buying batteries.

These take quite a while to charge and don’t last long. I tested them in two of the same item against regular batteries, and these died in a day. The regular batteries are still going strong. Not worth the hassle of constantly charging and waiting for the long charge time.

I use a lot of rechargeable batteries for things in my camper and house, but I'm not crazy about the big charging "bricks."These charge fast and efficiently individually and take up very little space.They last a long time and I don't have to recharge them often.I'm definitely buying more rechargeables of this kind again! 😊

I love these for my blink super fast charging

Got these for my baby swing, they’re good and a cheaper alternative than buying different batteries each time a set dies, but they don’t hold a charge for very long. I only use the swing maybe 2-3 times a week for 30-45 minutes max and I feel like I have to charge them after every use or their dead by the next time I go to use them. I would buy them again though.
