Preventing Lead-Acid 12 Volt Solar Battery Failures

Causes of lead-acid 12 volt solar batteries failures

When seeking out a 12 V A solar battery in the market, you’ll find that the lead-acid type 12 v batteries for solar energy is actually the most common. Now you might be wondering why since the technology surrounding this type of 12 v solar panel batteries are actually over 100 years old. This is because a lead-acid 12 volt solar battery still remains to be one of the most reliable and affordable type of batteries around which makes it perfect for residential and small business applications.

Unfortunately though, this type of 12 volt solar batteries also tends to fail due to 2 major reasons. One is that your 12 V A solar battery is frequently being run down too low and another is that your 12 v batteries for solar energy may be having a major build-up of lead sulphate on its plates which is attributed to roughly 80 percent of all 12 v solar panel batteries problems. The latter major cause is basically called sulfation.

Now you may be wondering what actually causes sulfation in a lead-acid 12 volt solar battery. Well there are actually a couple of reasons why such problems occur. One is not recharging your 12 volt solar batteries after exhausting it. Many people may not know this, but failure to recharge the batteries after using it all up can actually lead to the excessive build up of lead sulphate on the battery plates. This can also be caused by keeping the charge on the 12 V A solar battery under 75 percent for a long period of time.

Preventing Sulfation in lead-acid 12 volt solar batteries

Indeed, lead-acid 12 v batteries for solar energy are really susceptible to sulfation due to the reasons mentioned earlier. However, there is certainly something that you can do to prevent or at least reduce the extent of sulfation on your lead-acid 12 v batteries for solar energy. For one thing, it would help if you make sure that your 12 v solar panel batteries are fully charged at 100 percent when recharging it. Avoid charging it below its maximum capacity just because you need to use it right away. This is not a sound practice and will certainly hurt the service life of any 12 volt solar battery. You also need to be careful not to overheat your 12 volt solar batteries. Subjecting the batteries at temperatures above 100 degrees Fahrenheit for a long time will most certainly damage it.

Last but not the least; you also need to make sure that the electrolyte liquid inside the battery does not become too low as it evaporates over time. This is because excessively low electrolyte levels can expose the lead plates of the battery to air which facilitates the build up of sulphate crystals.
