Benefits Of The Best Solar Battery Tender
While they have been around for years, many people still don’t appreciate the importance of solar battery tenders. In fact, a good number are yet to invest in the gadget. Some view it as an unnecessary expense. The truth is that it is not. By investing in this accessory, you stand to gain in the following ways;
The Battery Is Charged Fully
The truth is that in most situations, the battery may indicate that it’s fully charged. However, in the real sense, it’s not. What will be shown is the surface charge which isn’t true. This normally happens when you boost charge it or use a high current. A battery tender usually trickle charges the battery by releasing small amounts of current at a time. And while this may take a little longer, it will ensure that the battery is truly fully charged. This helps to prevent cases of the cells forming sulfate which undermines the charge retention or the power being drained too fast.
The Charge Is Always Optimal
A battery will put out good performance if the charge is at its optimum level. Solar batteries are normally deep cycle and are a bit different from car batteries. They allow the charge to go much lower than the other battery. The solar unit can be drained by as much as 50 percent, whereas the automotive type shouldn’t be drained below 80 percent. Also, they have more recharging cycles. Using a battery tender helps to ensure the minimum level is never exceeded. Not only does this maintain the good performance, but it also extends the lifespan of the battery.
You Have Peace Of Mind
There are times that you will be away from home for several days or even weeks. This means that the battery will be losing some charge over time. And as you know, if it goes below a certain threshold, it can be a little tricky to revive it. In fact, you may need a special l charger to do this. But with a solar battery tender, it will automatically regulate the charge. It will charge it when it goes too low and maintains it at floating status when fully charged. You’ll, therefore, have peace of mind even when away from home.
Conclusion
This review has looked at some of the best solar battery tenders currently available in the market. This aims at helping to find the right product with little stress and also fast. The accessory is an important part of any solar system. It helps to regulate the power as well as ensure the battery’s charge is within the right level.
