Can I Use a Higher mAh Battery in Solar Lights?

Having a high capacity solar light battery is a must, especially in winter when the days are shorter and sunlight is scarce.

But can you actually replace your solar lights batteries?

If you are looking for a detailed answer, then you have come to the right place.

In this article, we will answer the most asked solar lights battery questions including:

  1. Can I Use a Higher mAh Battery in Solar Lights?
  2. How to Know Your Solar Lights Battery Voltage, Current, and Capacity?
  3. Types Of Solar Lights Batteries
  4. Do I Need Special Batteries For Solar Lights?
  5. Can you Charge Solar Lights Batteries Using a Charger?
  6. How Do you Charge Solar Lights for the First Time?
  7. Will Solar Lights Charge When they Turn Off?
  8. What Will Happen When the Battery Charge Gets too Low?

So without further ado, let’s jump right into the first question.

Can You Replace Your Solar Light Battery With a Higher mAh One?

Yes, you can replace your 400 mAh solar light battery with a higher 1000 mAh or even 2500 mAh.

However, you need to make sure your new battery matches your solar lights specifications including:

  1. Size: Make sure your new battery is the same size as the solar light’s battery house. This is pretty obvious, but you will be shocked by how many people actually miss this small detail
  2. Voltage: Different solar panels have different voltage outputs. Therefore, it’s important to make sure that your new battery matches this voltage.
  3. Current: Similar to Voltage, your new battery must match the solar panel current specifications.

It’s important to mention that you shouldn’t opt for very high mAh batteries, as the solar panel won’t be able to fully recharge them in one day, which negatively affects the lifetime of your battery.

How to Know Your Solar Lights Battery Voltage, Current, and Capacity?

Each battery has a specification table that includes:

  • Battery Type (Li-ion, Ni-Cd, or Ni-MH)
  • Size (AAA or AA)
  • Capacity (mAh)
  • Voltage (V)
  • Current (I)

Now, all you need to do is to buy a higher mAh solar light battery that matches both the Current (I) and the Voltage (V) of your old one.

Types Of Solar Lights Batteries

There are many types of batteries, however, the most commonly used types in solar lights are lithium-ion batteries, nickel-cadmium batteries, and nickel-metal hydride batteries.

1. Lithium-Ion Batteries (Li-ion)

They are lightweight and have a 10% self-discharge rate, which is pretty low compared to other battery types.

Further, they don’t suffer from the memory effect and have an expected lifespan of up to 1000 cycles making them the best rechargeable battery type out there.

The only disadvantage of this type is that they are on the expensive side, so if you are looking for a more budget-friendly solar light battery, this type might not be for you.

2. Nickel-Metal Hydride Batteries (Ni-MH)

Because of their amazing price, long lifespan, and relatively low self-discharge, Ni-MH batteries are the most common solar light battery type.

Ni-MH batteries are available in different sizes, capacities, voltages, and currents that will fit any solar light.

3. Nickel-Cadmium Batteries (Ni-Cd)

Unlike the Li-ion batteries, this type suffers from the memory effect and has around 20% self-discharge making them less efficient.

However, although Ni-Cd batteries don’t last as long as the Li-ion ones, they are in fact 3 times cheaper, which makes them an amazing choice.

Do I Need Special Batteries For Solar Lights?

No, any rechargeable batteries in the market will suffice as long as they match the voltage and current specifications for the solar lights.

Can you Charge Solar Lights Batteries Using a Charger?

Absolutely yes, just make sure the charger matches the voltage and current specification of the battery.

Also, some solar lights come with a dual-charging option, which allows you to charge the light using both a USB cable and a solar panel.

Can I Use Regular AA Batteries in Solar Lights?

Yes, solar lights can work using a regular AA battery, but they won’t be able to recharge them. In other words, they will work similarly to flashlights.

However, it’s not recommended to use regular batteries in solar lights as charging AA batteries may generate hydrogen gas, which can lead to an explosion.

But if you must so, make sure to turn off the light switch first.

How Do you Charge Solar Lights for the First Time?

Charge the lights for at least 12 hours before you install them, as it helps the battery to reach 100% charge, which prolongs its lifespan and increase its efficiency. (the same you do when you buy a new phone).

Will Solar Lights Charge When they Turn Off?

Yes, most solar powered lights will still charge even if they are turned off.

In fact, it’s recommended to turn the lights off for a few days every while, as it will allow the battery to get a full charge, which prolongs its lifespan.

What Will Happen When the Battery Charge Gets too Low?

To save energy and help the light to last longer, the solar light will emit dim light instead, yep, that’s it, they will gradually lose brightness until they start charging or till the batteries are empty.

Note: Some solar lights don’t have this option and they will emit full brightness light until they drain the battery.
