Tip and tricks for deep cycle battery
Deep cycle batteries can last for years. However, most of the buyers, after purchasing a deep cycle battery, does not take care of it at all. As a result, they have to find replacement options. But if you take the right precautions, then you can get the most out of your battery.
And here are some tips and tricks to keep your battery healthy:
Avoid Leaving The Batteries Depleted:
You should never leave your batteries depleted. Because when the charge in the batteries starts getting low, the crystals start forming on the plates, and this process is called sulfation.
And in case if you fail to recharge your batteries on time, then the sulfation process will start working much faster. As a result, the batteries will get damaged completely. Hence, in order to preserve the batteries, you must recharge it from time to time.
You can also consider buying yourself a voltmeter to determine the ideal time to recharge the batteries. Just make sure you are keeping the battery charge up to 50%, mostly.
Switch off the battery completely:
Even if you turn off all the appliances in your recreational vehicle. There are certain things that can discharge your battery, such as gas leak detectors, antenna power boosters, stereos, and other things. And to prevent these loads from discharging the battery, you can simply disconnect the battery to everything and switch it off when it is not in use.
Check The Electrolyte Levels Periodically:
Maintaining the battery life is something that we all want to do and have to do. And to do so, you must keep the electrolyte at the acceptable levels.
In case if the electrolyte is low, then you must proceed to add more distilled water. In case if you do not have distilled water around you, then you can also mineral free water. But make sure you are not adding tap water, as it will cause calcium sulfation. As a result, your battery will get damaged permanently.
Consider Using Three-Stage Chargers:
Just in case you didn’t know, batteries should be charged in three stages, which are the bulk charge, abortion charge, and float charge.
The first stage helps the battery to get back to 90%, the second stage helps in charging the remaining 10%. And the third stage maintains the full charge.
Also, if you are wondering how you can perform three stage charging, then let me tell you that the market has a variety of Three-Stage Chargers. Just pick one of them, and you are good to go.
Only Add Water After Recharges:
In case if the plates of your battery seem to visible, then you must add water after charging the batteries. Like whenever electrolyte gets low, the plates of your battery starts getting exposed. Hence, you need to add water to cover the plates first before performing recharges. You can simply do it by leaving the vent caps on batteries while charging. This will limit the loss of water.
