A notice: ✔ Do not mix 1.5V lithium batteries and 1.2V Ni-MH batteries as this may cause the device to malfunction.✔Keep away from water.✔ Insert carefully and do not damage, open or short-circuit. Insert carefully and do not damage, open or short-circuit.✔Do not throw into fire. 1.Voltage Output Stability 1.5V Li-ion D battery: it adopts a buck circuit design, which can maintain constant voltage output throughout, which means that the voltage fluctuation is small during the use of the battery, and it can provide a stable power supply for the equipment. 1.2V NiMH D battery: on the other hand, it is a slow voltage reduction, and its discharge cut-off voltage is usually set at 0.9V~1.1V, so the voltage will be gradually reduced in the process of using. 2. Energy density and usage time 1.5V Rechargeable lithium D batteries: usually have a higher energy density, which means that lithium batteries can store more power under the same volume or weight, and therefore usually provide a longer use time. 1.2V NiMH D batteries: although also have a higher energy density, but compared to lithium batteries, its energy density is usually lower, the use of time may be slightly shorter. 3. Charging performance 1.5V lithium Rechargeable D batteries: charging speed is usually faster, can be fully charged in a shorter period of time, suitable for occasions that require frequent charging. 1.2V nickel-metal hydride batteries: charging speed is relatively slow, it takes a long time to be fully charged. In addition, NiMH batteries also have a certain memory effect, that is, if the battery is not fully discharged before charging, it may affect the capacity and life of the battery. However, modern NiMH battery technology has greatly improved this. 2X C batteries 4X C batteries 2X D batteries 4X D batteries 6X D batteries Add to Cart Add to Cart Add to Cart Add to Cart Add to Cart Customer Reviews 4.0 out of 5 stars 27 4.0 out of 5 stars 27 4.0 out of 5 stars 27 3.7 out of 5 stars 9 4.0 out of 5 stars 27 Price $15.99$15.99 $35.99$35.99 $19.99$19.99 $35.99$35.99 $39.99$39.99 Battery quantity 2 4 2 4 6 Charging method USB-C, Type-C USB-C, Type-C USB-C, Type-C USB-C, Type-C USB-C, Type-C LSD: low self-discharge ✓ ✓ ✓ ✓ ✓ Output voltage: 6000mWh 6000mWh 8800mAh 8800mAh 8800mAh
