The GEILIENERGY AA NiCd Rechargeable Batteries are safe and reliable batteries to replace the used up batteries of your solar outdoor lights. These rechargeable batteries are suitable to replace 600 mAh, 800 mAh, etc. These are ideal for Intermatic and Malibu Solar Garden Light. Shop for rechargeable solar batteries online at Target. Choose from contactless Same Day Delivery, Drive Up and more.

Because I'm retired, I camp a bit in the national parks/forests, do nuisance bear removal, mountain rescue and disaster cleanup where there is usually no power. Seems kind of silly to run a loud generator just to charge a handheld scanner.
I recently received a solar AM/FM/NOAA radio as a gift. The thing is so small I thought it was a toy as it almost fits in my hand. I let it charge in the sun and turned it on. I was in shock it worked so well. Amazon sells them for $30, so they are not expensive to make.
Now, if GRE would only make a solar handheld scanner. I reckon there would be no room on top for a solar panel. I'm sittin here looking at my PSR-800 and there is plenty of room for a solar panel on either side. Lay it on its side in the sun and BOOM, a few hours later the radio would be charged.
Till someone makes one, I am looking for a portable, solar charger. Any better ideas out there?

  • The rechargeable batteries inside of your solar light will last anywhere between three and four years without requiring replacement. Even though rechargeable batteries are designed to reduce the amount of waste generated by batteries, they’re still not lifetime devices.

Plug-in cars manufactured in 2010 or later typically use lithium ion batteries. Vehicles built before 2010 may have used lead acid, nickel metal hydride, or nickel cadmium batteries.


A number of characteristics affect battery performance and use:

  1. Cost
  2. Efficiency
  3. Energy density (the amount of useful energy stored by the battery, per unit of weight)
  4. Power density (the rate at which energy is converted into work, per unit of weight)
  5. Expected life
  6. Environmental impacts

Lead acid batteries


Lead acid batteries are commonly used to provide startup or backup power in gasoline- and diesel-powered vehicles. In addition, lead acid batteries have often been used in many special-purpose vehicles, including fork-lifts, low-speed utility vehicles and golf carts. Some do-it-yourself conversion kits for electric vehicles also use lead acid batteries.

Lead acid batteries are comparatively heavy—and dangerous because they contain lead, which is toxic, and sulfuric acid, which is a hazardous material. Lead acid batteries also emit hydrogen gas while being charged, which creates a fire and explosion hazard unless adequate ventilation is provided.

Economic incentives and regulatory constraints ensure that 99 percent of lead acid batteries are recycled.

Nickel cadmium batteries

Nickel cadmium batteries, once commonly used to power consumer electronics and power tools, have largely been supplanted by nickel metal hydride and lithium ion batteries. Some homemade electric vehicles may still use nickel cadmium batteries.

Cadmium is toxic, and proper disposal or recycling of these batteries is important. However, smaller incentives and fewer regulatory constraints mean that fewer of these batteries are recycled than lead acid batteries.

Nickel metal hydride batteries

Nickel metal hydride batteries are used in many hybrid electric vehicles, such as the Toyota Prius, Honda Insight and Ford Escape. They are also used in many consumer electronics and power tools. These batteries have good power density but lower energy density and efficiency compared to lithium ion batteries.

Lithium ion batteries

Lithium ion batteries have replaced nickel cadmium and nickel metal hydride batteries in most consumer electronics products that use rechargeable batteries. Lithium ions provide higher energy and power densities and better energy efficiency than earlier battery systems. This makes them the battery of choice for many plug-in vehicles planned by major automakers.

Taking advantage of this, the Tesla company uses thousands of lithium-cobalt-oxide cylindrical batteries in its battery electric sports car. This approach requires a greater investment in the battery management system to ensure safety and battery life.

Recycling of lithium ion batteries is increasing in the United States. Also, automotive manufacturers and utilities—including TVA—are exploring ways to re-use batteries that are too depleted for vehicular use but still have enough life remaining for other uses. One application might be to use these partially depleted batteries to smooth out the variability of distributed generation sources such as solar panels.
