Quick Answer: How Much Water Should Be In A Deep Cycle Battery?

Do I need a special charger for a deep cycle battery?

A charger specifically for deep-cycle batteries can provide increased amperage to the battery and vary the amps sent.

With a built-in monitoring system, these chargers typically charge a battery in phases and protect against overcharging, which is optimal for the battery’s lifespan..

How often should you charge a deep cycle battery?

Batteries should be equalized occasionally to make sure each cell is equally charged. Apply a controlled overcharge once every 30-90 days, or whenever individual batteries are imbalanced (reading a different voltage or specific gravity). Check water level before initiating an equalize charge.

Can you add water to a marine battery?

Fill each cell with distilled water until the cell is full up to the top of the fill hole. Do not overfill the cell as that will cause electrolyte solution and battery capacity to be lost.

Should I add water or acid to my battery?

It’s important to note that battery owners should never add sulfuric acid to their battery. During normal operation batteries will only consume water – and not sulfuric acid. When your battery’s electrolyte is observed to be low, filling the battery with water will keep the battery healthy and safe for use.

How do I know if my marine battery is bad?

If your battery is reading 0 volts, chances are the battery experienced a short circuit. If the battery cannot reach higher than 10.5 volts when being charged, then the battery has a dead cell. If the battery is fully charged (according to the battery charger) but the voltage is 12.5 or less, the battery is sulfated.

Can I use bottled water in battery?

Bottled or Tap? Because tap water contains minerals and natural content that could corrode the battery, it’s best to used bottled water. Use distilled or deionized water to fill your battery, as it doesn’t contain the mineral content of tap water.

Can you use tap water to fill a battery?

The answer is no, according to an auto electrician. The best way to fill a battery is with deionised, demineralised or distilled water. … The minerals in the tap water coats the plates and fills the pores, so they are no longer in contact with water, but with the minerals, which causes the over working of the battery.

How much water should be in a battery?

The water level should be about a ½ inch above the tops of the plates to be considered in normal range. When adding more water, make sure you use distilled water. Tap water contains minerals that can diminish the performance of the battery and can increase the rate at which they self-discharge.

What happens if battery is low on water?

Low water level means the electrolyte will be out of balance and the battery cells will become too acidic resulting in sulphation on the battery plates. The non-conductive lead sulphate crystals will hinder flow of current through the electrolyte.

Can you overcharge a deep cycle marine battery?

If they are overcharged voids can form in the gel which permanently reduces the battery capacity. For deep cycle applications however the Sealed Lead Acid type of battery can be a great deal more expensive than a comparable Flooded Lead Acid battery.

How long do deep cycle batteries last?

six yearsMost deep cycle batteries can last up to six years with proper care and charging (depending on the frequency of use). It’s up to you to make sure that your battery isn’t being damaged by your charging routine.

What can I use instead of distilled water?

4 Substitutes for Distilled WaterMineral Water. The first alternative to distilled water is mineral water. … Spring Water. Then, you’ll find spring water. … Deionized Water. Also known as demineralized water, this type of H2O has not a single ion of minerals. … Osmosis Purified Water.

What happens if you don’t use distilled water in a battery?

Use only distilled water when filling a car battery. Using anything other then distilled water will cause permanent failure of your battery. … Do not over fill the water level. This can cause the acid water mixture to leak.

What happens if a deep cycle battery goes flat?

If your battery shows a good voltage when it’s fully charged, but quickly drops voltage to 11V or less when using power, this usually means the battery has a faulty cell and needs replacement. … When a deep cycle battery is fully discharged (dead flat), it should reveal a reading of approximately 10.5V.
