No matter how strong your batteries are, one day they shall need to be replaced. Why you ask? Once you start using the battery it starts to depreciate and over years of depreciation the battery eventually dies.
Depreciation is not the only reason why your batteries may need replacement. In this post, we are going to discuss other various factors that may lead to solar batteries replacement. We will also give you tips to help maintain the effectiveness of the battery. Stick around to learn the dos and don’ts when it comes to solar batteries.
Do solar batteries need to be replaced?
Solar is the cheapest and the cleanest form of energy. After setting up the solar equipment, the solar panel harvests energy from the sun which is then stored in solar batteries. As simple as all these sounds, do you know your battery might become defective and need a replacement?
Every gadget has its expiry date. Others last longer depending on the quality and the maintenance care provided. This applies to solar batteries. Most solar battery manufacturers indicate that their batteries last up to 30 years without the need for a replacement. However, not all batteries get to complete their life span. Here is why.
Most people assume that batteries do not need any care. The opposite is true. If you do not maintain your batteries, they might end up getting damaged.
- Solar batteries require a fluid refill once in a while to prevent the lead oxide plates from drying. Distilled water is the best refill fluid as it does not react with the plates.
- Regular cleaning of the battery and the solar panel is required if you want your battery to last longer. A dirty solar panel will inhibit the charging process of the battery.
It is possible to assume that solar energy can cause battery overcharge. You might even not know that is a dangerous thin When the battery overcharge the plates might burst and or even worse explode.
- To prevent an overcharge, it is better to invest in high-quality maintainers. Maintainers also known as battery tenders automatically shuts off any current from reaching the battery once it is fully charged.
- Check if your solar panel has a hot spot. Hot spots collect most heat from the sun and all the energy is directed to the solar battery which might lead to overcharging.
There is a high possibility that a drained battery will not reach its expiry date. When the battery is completely drained the electrolytes plates dry up and constant draining eventually damages the battery.
- Invest in a solar battery trickle for effective charging even on bad weather.
- A solar battery tender stores some extra charge on the battery if the battery is not in use to prevent the battery from draining.
- Place the solar panel where it is exposed to the sun. During winter .
- Do not buy a solar battery that has been in storage for more than six months. This batteries cannot hold charge for long.
- Ensure you setup the solar lights system correctly. Some setups might be reversing the solar charging process causing a discharge.
- Your solar sensor should be up and running throughout. A solar sensor automatically shuts he solar lights during the day for charging.
Low quality solar batteries
It is no brainer, low quality products cannot serve you for long. A cheap solar battery lack some important features that make your battery last longer.
- Invest in a high quality battery. High-quality batteries can store charge for a long time. Their discharge rate is also low.
- Make sure you read customer reviews before you buy any solar batteries. This way you will know what to expect with the battery you will buy.
Sometimes the battery not reaching its life span is not your fault. You might have bought a battery with defects. If you happen to notice your battery is not storing charge for long, contact the manufactures for replacement. Manufacturers of solar batteries offer 30 years on their items.
Do you have to replace lar batteries?
A faulty battery will not serve you as expected. The lights might be going off during the night since the battery cannot store charge for long. On worst cases the battery might not charging.
To reduce the frustration that come with a battery not working as expected, it is better to have a replacement. So how do you know you need to replace the solar battery?
When Should I Replace My Solar Battery?
There a number of reasons why you should replace your solar batteries. One of the reason is to reduce the frustration of being in the dark. Below are some of the common indicators you should change your battery.
- In case of a pool of liquid pool near the battery which indicates the battery is leaking.
- If the battery cannot light up your residence the whole night. This means the battery is drained.
- When the battery is not charging entirely
- If you notice discoloration near the base of the battery.
- Rechargeable batteries are replaced once in four years.

A standard solar battery will cost you around $5000-$8000+. This however does not include the cost of installation.
How long do solar rechargeable batteries last?
Most solar lights companies indicate that their rechargeable batteries can last up to four years without a replacement. You should again read customer reviews to reduce future frustrations. Rechargeable batteries are quite affordable.
You an get a set of ten rechargeable batteries for $200.
Can you Replace Solar Lights Batteries with Regular Batteries?
Solar lights batteries have specifications that are unique. For example most solar batteries use lithium-ion or flooded lead batteries while normal batteries are lead-ion. Normal batteries have thin lead-oxide plates that cannot withstand constant discharge and recharge.
Normal batteries also have very low power holding capacity. For this reasons normal batteries are not ideal for solar lights.
Should I Use High capacity Batteries in My Solar lights?
High capacity batteries require high current to charge. Solar panels to cannot produce the required amount of current to recharge them. Therefore high capacity battery are not ideal for solar lights.
Frequently Asked Questions
Are rechargeable batteries expensive?
Rechargeable batteries are quite affordable. You can get a set of ten batteries for $200. This however depends on the type and the capacity.
What is the life span of solar light batteries?
Most solar light batteries life expectancy is between 5-30 years. Proper maintenance like regular cleaning of the solar panel and the batteries will improve the performance of the battery.
