Replacement NiMH Batteries C4000mAh 3.6 volt with good cycle life

Application:

1. Lighting: emergency lighting, emergency power supply, solar lights, searchlingts, flashlights

2.Power tools: electric drills, planers, saws, power granted

3. Electronic toys: remote control car, remote control boats, aircraft, model aircraft

4. Communication equipment: cordless phones, walkie-talkie

5. Other uses: electric shavers, massagers, electric tooth brush

Product performance:

1. No memory effect (compared to Ni-Cd).

Ni-MH can be partially charged (for example, on a cloudy day) and fully charged to maximum capacity on the next sunny day. There is a small amount of discharge (trickle discharge) during storage, so it is best to put Ni-MH batteries in your garden solar lights before dawn on a sunny day. They will then be ready for you to enjoy the nighttime fun.

2. Long shelf life.

They can remain unused for between 3 and 5 years. However, we recommend that you use new Ni-MH rechargeable batteries as soon as possible to ensure that these solar lights always shine.

3. Ni-MH rechargeable batteries for solar lights are almost always more expensive than Ni-Cd batteries.

Ni-MH rechargeable batteries are priced to get your solar garden lights up and running with the best options available.

Solar reading light batteries can be replaced with Ni-MH rechargeable batteries. Remember, do not mix the chemicals in your solar lights (if they require 2 or more batteries). Use only Ni-MH or Ni-Cd and do not use one of these in 2 or more battery lights. In addition, the typical lifetime of both batteries is about 2 years (nighttime operation/use). Therefore, if your solar lights are about 2 years old and you notice a decrease in output at night, it may be time to replace them.

4. Ni-MH rechargeable batteries are considered to be more environmentally friendly than Ni-Cd batteries.

Cadmium is classified as a toxic element and therefore needs to be disposed of properly. There are many recycling stations, but if for some reason they end up in the trash, Ni-MH batteries can be recycled (recommended), but if there is no recycling option, it's not "bad" to throw them in the trash.

Performance Curves for Ni-MH Cell:

1. Ni-MH Cell Charge Curve At 0.1C For 16h At 55 Degree

2. Ni-MH Cell Discharge Curve At 0.25C At 55 Degree

3. Ni-MH Cell Charge Efficiency At Different Temperature

4. Ni-MH Cell Cycle Life Curve

What Are the Advantages of NIMH Batteries?

High Energy Density

One of the main features of NiMH batteries is their high energy density, which allows them to store more energy in a smaller package. This makes them ideal for portable electronics, where space is often limited. In addition, NiMH batteries have a low self-discharge rate, which means they lose less energy when not in use, making them more convenient for devices that are used infrequently. This also means that NiMH batteries can be charged and stored for longer periods of time without losing their ability to hold a charge.

No Memory Effect

Another advantage of NiMH batteries is that they do not have a "memory effect", meaning that they begin to lose their ability to hold a charge over time if they are not completely depleted before recharging, but this is not a problem with NiMH batteries because they can be recharged at any time without affecting their capacity.

Environmentally friendly

In addition to their high energy density and low self-discharge rate, NiMH batteries are also environmentally friendly. NiMH batteries do not contain hazardous substances. This makes them a safer and more responsible choice for the environment.

Long life span

Another important feature of NiMH batteries is their long life span. When used and charged properly, NiMH batteries can last for hundreds of cycles, making them an affordable option for powering devices that require frequent recharging.
