Our rating: 8 / 10

EBL AA Rechargeable Batteries

Check Price on Amazon

Pros:

  • The price, while still a bit higher than I would like to pay, is reasonable and in line with other comparable batteries
  • AGM battery format is great for solar lights since it lasts a lot longer than other types of batteries
  • The price is more reasonable than other battery types for this use. I know Amazon is also a good place to find a good deal on this battery
  • Safety features built into both the batteries and the solar lights batteries are a great addition for this sort of battery use, both to prevent from fires and to prevent drain if the lights are accidentally left on during a blackout
  • These batteries charge fully in just about 5 hours, which is a little longer than standard AA batteries require on a regular basis to refill their charge

The batteries from other sellers only lasted a few months and then they started to die. These batteries are sealed and should last almost forever.

Coming in a close second to the EBL batteries is the not-so-expensive batteries from super-seller, Digipower. These batteries have been getting rave reviews on Amazon, with customers saying that they are extremely happy with the performance and the price.

6. RELIGHTABLE AA NiCd 600mAh 1.2V Rechargeable Batteries

Our rating: 8 / 10

RELIGHTABLE AA NiCd 600mAh 1.2V Rechargeable Batteries

Check Price on Amazon

Pros:

  • Works great as replacements for solar lights
  • The batteries have a long shelf life
  • Can be used for a variety of small electrical items

Rechargeable batteries are a bit of a difficult choice for solar lights. NiMH batteries are ideal in many ways but they tend to lose the ability to hold charge very quickly and require charging on a regular basis. The lithium battery does not need to be recharged as often but it has a lot of disadvantages like being dangerous if damaged. However, there is a brand that manages to combine the best of both worlds; rechargeable and non-rechargeable AA batteries. It is a rather new technology that is slowly taking the world by storm; nickel cadmium batteries. In case you didn’t know, nickel cadmium batteries are rechargeable. They can be recharged hundreds of times and do not lose their ability to hold charge.

The ReliGhtable rechargeable AA batteries cost about as much as regular alkaline batteries but they quit working way sooner. They run about 30% longer than alkaline batteries. They are perfect for non powered devices that can be operated by AA batteries.

7. Tenergy Solla Rechargeable NiMH AA Battery

8. GEILIENERGY Solar Light AA Ni-CD 600mAh 1.2V Rechargeable Batteries AA Rechargeable Batteries

Our rating: 8 / 10

GEILIENERGY Solar Light AA Ni-CD 600mAh 1.2V Rechargeable Batteries AA Rechargeable Batteries

Check Price on Amazon

Pros:

  • The batteries can be recharged from solar panels
  • Safe to use as they are rechargeable
  • Cheap
  • Last for a relatively long time

Cons:

  • They are Ni-CD batteries, so they should not be discharged completely
  • The product is sold in packs of 20, so if only one is needed then a whole pack would be wasted

Solar light batteries should not be stored in freezer as there is a high risk of water leakage if this is done. They should be stored in a dry and clean place away from fire sources like lighters and matchsticks. Ventilate the batteries when charging and discharging. This is for better performance. Use 1.2 V AA Ni-CD 600 mAh GEL renewable energy battery with solar lights

10. Moonrays 47740SP Rechargeable NiCd AA Batteries

Our rating: 5 / 10

Moonrays 47740SP Rechargeable NiCd AA Batteries

Check Price on Amazon

Pros:

  • Long shelf life
  • You can use one or more per device, depending on size
  • The AA battery is compatible for rechargeable operation
  • Cost efficient – NiCd AA batteries are relatively inexpensive

Cons:

  • Nickel Cadmium batteries operate best at high temperatures
  • You need a charger specifically for NiCd batteries

As we near 2020 it is safe to say that the NiCd AA batteries are still the best for everyday use. They give the best energy density you can find on the retail market. This allows you to charge a power pack and have it give you a great amount of hours of run time.

Another great thing is that you can use most rechargeable AA batteries in an AA solar light, provided that the unit comes with a charger you can connect it to. This is an important point to consider because, some lights are connected to a mains battery pack, which means you can't use the AA NiCd batteries in them. By doing this, you save a lot of money over the long-run and cut down on the amount of batteries you are using.

Frequently Asked Questions (FAQ)

What are the best batteries for solar lights?

Solar lights are just one of hundreds of resources that have been developed as a result of solar technology. Theoretically, nothing new has been created, other than the fact that electricity is now being harnessed by the sun instead of from the ground.

Therefore, solar bulbs, like any other electrical light, need an energy source to power them. Most solar lights use AA or AAA batteries. The number of AA or AAA batteries required for a solar light will usually depend on the lumins of light it is capable of producing.

It is important to remember that batteries are not included in the packaging of most solar lights. You'll have to purchase batteries separately. To make life easy, here's a list of the best batteries for solar lights.

Do you need special batteries for solar lights?

Solar lights use battery or induction to charge the lights.

The battery-powered lights work much like the flashlights work. When there is no more battery power, they will go off.

The induction-powered lights work with a dark lens. So you could just let them charge for a few hours or days and then turn them on for a few hours or days under the sun.

Can you use any rechargeable batteries in solar lights?

Unfortunately, no, only specially designed solar batteries are optimized for the unique demands that solar lights place on batteries.

The most important metric of solar batteries is their number of cycles. The average quality solar light is rated for 1000 cycles. Thus, you need a battery that is rated for at least 1000 cycles.

Some solar batteries only work with one or two lights, while others are meant for a string of 4-6 lights. It pays to look at the number of lights that the solar battery is compatible with.

Poor quality batteries can ruin a solar light. It's important to read reviews and do some research by asking questions in a forum where other users have shared their experiences.

Can I use 600mah instead of 400mAh?

Only if you use them indoors. Make sure you recharge them thoroughly, once a day. Be warned that they'll probably discharge faster, which means that you'll have to recharge them more often.

Solar powered lights typically have both mAh and LUMENS integrated into the packaging. LUMENS is a measurement of light source intensity and is given in the "lumen string".

The higher the Lumen string, the brighter the light.

Most manufacturers commit to the safety standards required and typically go over it, so it is unlikely you'll get a light string less than 400mAh.

The majority of solar lights are built for outdoor use and can withstand bad weather conditions. Most come with a standard rechargeable battery that can either be removed and replaced or comes with a rechargeable unit. Some have solar panels on the lighting unit itself that recharge the battery while it is out and about and others have rigid solar panels that don't have to be removed.

Conclusion

A lot of people are opting for solar lights for indoor and outdoor use. The number of reasons for this choice is astounding and they are all for good. We’re sure however that for you, it’s more of a matter of convenience and being energy conscious. This article will hopefully give you a better idea of the different batteries and their characteristics so that you can choose the best options for your lights.
