    I have many of these battery, I found early versions are more using time then the last I bought, early each 1.5 D weight about 97.8g and last one I bought is 88.6g, I mixed them 4 using at same time on my little fan, when stop working that always 88.6 running out power first, when they are recharged always 88.6g fully charged then others. I have 9 of these battery. Generally they are good value.

    I’m using (2) D cells in a small hand pump. Very happy with these. They hold a steady 1.55 volts for a long time which is important to keep the pump running at speed. Its only right at the end of the charge where the voltage appears to drops off. The pump can move about 200 gallons of liquid up 2 feet before I notice it slowing down. Charging via a USB-C charger with my own cables. When charging each draws 5.09volts and 0.55 amps with my usbC 29watt charger. No big temperature rise while charging. Takes about 4 – 5 hrs to charge up fully from dead with my charger.

    Great batteries, nominal voltage runs above normal alkaline AAs, so, for example, if you use clippers, they run a bit faster. It is good for the environment to reuse things, and it is a no-brainer to have these batteries.

    I am very happy with these for a particular use (infrequently used remote controllers). I hope I did not damage a battery after using them in a higher amperage device – one acted differently while charging afterward.

    Although the seller sent me the wrong size battery (D instead of C), they are sending me the correct one.I noticed that their D battery is larger capacity than other rechargeable lithium batteries out of China.I am using this in an outdoor light and will probably learn that the smaller capacity D battery from another seller will cause me to change the light fixture more than I would like.

    I had bought portable FM AM HD-Radio boombox stereo, as the reviews were not as 5 stars because other customers ended up to replaced C batteries too often. As NiMH battery has little under voltages. So, I had bought 4 C Cells Lithium-ion 1.5 regulated voltages even at just 20% of charged, it still reads at 1.5V. I has ended up with long playing time per charged times 1,000 charging cycles and or 5 to 10 years of whole batteries lifetime.

    I have been looking for a suitable replacement for the D Cell batteries that my equipment needs. I’ve tried various brands of the large capacity NiMh batteries and none worked properly. Immediately upon installing freshly charged NiMh batteries, my device would show the batteries where at half capacity (as detected by the equipment). After 45 minutes to an hour it would start to tell me it was time to turn off due to battery depletion. So I decided to give the 1.5 Volt D Cell Lithium rechargeables a try. I was a bit dubious but what the heck. I ordered 2 sets of the D1 batteries (a total of 4 batteries, my device requires 3). I gave them an initial charge and plopped them in. Well, much to my surprise, after 5 hours the device was still showing a full charge. I had never gotten this even with brand new high quality Alkalines. I turned off the equipment and waited a couple of minutes to see if the device would go through a cold start because it draws a bit more current from a turned off condition. No problem, it started right up showing a full charge. At this point I ordered a couple more sets so I would have a back up. The only thing left to see is how fast these will self discharge. Since the battery is always in an active state it has to draw at least a small amount of current, so I don’t expect them to have the same shelf life of a regular style battery. Anyway, I just wanted to say that I am very happy with these batteries. Hopefully I with get many cycles out of them.

    I use the battery for a child vibrating chair. We’ve been using it for about a month, the battery is yet to die. We often forget to turn the vibrating button off. Needless to say we’ve gotten good use out of the rechargeable battery. I haven’t recharged since the first time.

  9. Brandon Milum

    I’ve been gathering some prepping items, in case my power goes out, or just to go camping. I bought 4 of these batteries, and when our power was out for a week during a snow storm: these batteries worked, and lasted. I’ll definitely buy more in the future.

    Pretty good so far.Be aware it is type C USB, but the cable or comes with works fine.The indicator lights work well to let you know when it’s finished charging.Works well with xbox game controller.
