  • 4 Secrets To Enhancing Your Battery Lifespan

Why can’t I just use my car battery for my solar system? Everyday people ask this question and the answer still remains same –No, you can’t. Only a deep cycle battery is recommended.

 A deep cycle battery sometimes called deep charge battery is often used in off grid power system such as solar energy  can be charged and recharged as possible to provide sustainable power over a long period of time. This isn’t like a car battery. The car battery is a lead-acid battery. The car battery stays fully charged and provide short burst of high current for ignition and low current for lighting.

The need for deep cycle batteries for off grid solar systems cannot be over emphasized- It is to our solar systems what food is to our body. Your deep cycle battery should be fully charged during the day by the solar panel and deeply discharged after sunset. But the question is:  how do you know the right deep cycle battery to go for? Below are a few tips on things to be on the lookout for.

Voltage rating
It is important that the voltage rating fits the battery charger and the off grid inverter rating.

Note the capacity in AH (ampere hours)

You want the highest possible. If you don’t get a very efficient battery you might have to compensate for its
inefficiency with larger solar panels. Thus the need to watch out for this characteristic is very necessary.

Life span
A good deep cycle battery lifespan is typically around 3-4 years. Anything below this might put you at disadvantage of incurring additional expenses.

Just like your solar panel, your battery also should be handled with care.

  1. Keep batteries in shaded relatively cool place that is naturally ventilated. If you prefer to keep your batteries in an enclosure for aesthetics, ensure that the enclosure is well perforated to allow for air circulation.                                                                                                                                    
  2. Ensure your batteries are fully recharged before depleting them all over again.                                                                                                                      This is one of the best treatment you can give your battery; it will preserve the battery cells and you will enjoy longer battery life span                     
  3. Use a quality charge controller and inverter from a trusted manufacturer.                                                                                                                          This is important because your batteries must be getting the right charging current. Low charging current may be insufficient to keep the batteries in good condition, since it takes longer to get fully charged.                                                                                                                                       
  4. Check the health of your batteries using a battery analyzer regularly.                                                                                                                                This will help you avoid sudden power cut-off due to battery failure and aid early detection of fault.

So here you have it, the characteristics and care of a deep cycle battery.
