How To Charge Them?

This is another aspect that has to be taken into consideration after discussing their maintenance. Charging is very important, too, and it must be done properly in order to not damage your product. Charging needs to be done in stages and usually, there are 3. A 3 stage charger might be the best solution if your vehicle does not have one you can purchase it individually.

  • Turn off the vehicle – Yes, it may sound silly but it is absolutely necessary to make sure that the vehicle is not on. This way you will prevent injuries or other unexpected accidents. After doing this, remove the accumulator wires with a wrench, clean it with a brush and a rag, then apply petroleum to avoid rust.
  • Place the charger to the accumulator – Connect the positive side to the red connection and then place the negative side with the black connection. Make sure that you charge it only when it naturally discharges to avoid ruining it over time.
  • The 3 stages of charging – As we have mentioned above accumulators need to be charged in 3 stages. The first one is the bulk charge which will get your accumulator to 80-90%. The second one is the acceptance charge when the accumulator gets close to totally charge and when the third stage comes in there are only a few moments until it is fully charged.

How to Increase the Life of Your Accumulator?

We all want a device which battery’s last for a long time but unfortunately, this is not possible. On the other hand, there are some solutions in order to make it provide more energy. This can be solved by taking into consideration some tips and features. If you will properly follow our advice you can make sure that you will offer it a longer life. So, in order to obtain this keep in mind the following tips:

  • Do the routine maintenance and make sure to charge it as soon as it got discharged. Recharging an accumulator in a timely way will prevent sulfation.
  • Overcharging and hot temperatures will ruin batteries. In this case, make sure that you constantly check the water levels more frequently.
  • Be aware of parasitic loads because they can destroy the accumulator. If your RV is equipped with a battery, turn off the switch when you are not using the RV.
  • Replace tap water with mineral free water or distilled water. Tap water can cause sulfation and that can damage your accumulator.
  • Water the batteries only after they are charged. When the battery is fully charged fill it will water to the bottom of the vent.
  • The plastic and lead that batteries are made of can be recycled. Almost 100% of the battery is recycled so make sure to recycle all your old accumulators.

Frequently Asked Questions

?Will it self-discharge if I do not use it?
Yes, it will. All lead-acid accumulators discharge over time. Deep cycle accumulators are specially made to diminish the amount of self-discharge but you should report for a 3% loss of charge each month the accumulator is not used.

?How can I increase the life of the accumulator?
Proper care and maintenance is totally the best way to increase the life of your accumulator. Also, make sure that you charge them only when they self-discharge. Store them carefully and do not leave them inside the vehicle during winter or periods of non-use.
?What are the causes of accumulators breakdowns?
The most common causes of accumulators failures are the process of sulfation, heat or overcharging, redundant vibrations, freezing the electrolytes and using tap water instead of distilled water when filling them.

Finally, our recommendation is to properly take care of your accumulator and it will have a long lifespan. These accumulators can last up to 5 years if maintained accordingly. Also, remember that it takes less time to drain than it does to recharge them so make sure that you are patient in order to let them recharge. As mentioned above, a well-done maintenance is the best thing to be done.
