Quick Answer: What Is The Longest Lasting Deep Cycle Battery?

How do I know if my deep cycle battery is bad?

How to Know If a Deep Cycle Battery Is BadDo a visual inspection of the battery.

Charge the battery fully before testing.

Have a copy of the manufacturer’s specifications for the battery nearby, as you will need to refer to them as you test the battery.Take a hydrometer reading of all the cells in the battery.More items….

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.

What is the longest lasting trolling motor battery?

AGM BatteriesAGM Batteries are completely sealed, generally last longer on a charge and have a longer life-span. While a traditional deep cycle battery might last approximately two years, an AGM deep cycle battery will usually last between three to four years.

What amp should I charge my deep cycle battery?

It is better to charge a deep cycle battery at a higher charge rate like 6-amps, 10-amps or higher. However, check you battery specifications for the proper charge rate.

What should I look for when buying a deep cycle battery?

The most important consideration in buying a deep cycle battery is the Reserve Capacity (RC) or Ampere Hour (AH) rating that will meet or exceed your requirements. RC is the number of minutes a fully charged battery at 80 degrees F is discharged at 25 amps before the voltage falls below 10.5 volts.

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 is the best way to charge a deep cycle battery?

There are two main approaches to charging up a deep cycle battery. The first is to charge the battery while it’s on the boat already, in the fixed position. The second is to take the battery out of the boat and make use of a portable charging unit to top the battery up to full.

Is there a difference between deep cycle and marine battery?

A deep cycle marine battery, or trolling battery, has several design differences. One key is plates: It has fewer, thicker plates allowing the battery to provide continuous power output over long time periods. Deep cycle batteries can be entirely drained and recharged many times over, cranking batteries can’t.

What is the best type of deep cycle battery?

What is the best Deep Cycle Battery?1) Lifeline AGM. Lifeline batteries are the best of the best. … 2) Fullriver DC Series. Our close second recommendation goes to the Fullriver DC (Deep Cycle) Series. … 3) Optima Batteries. … 4) Ultimate Extreme VO AGM Batteries. … 5) Pure Energy AGM.

Is it bad to drain a deep cycle battery?

Automotive batteries will generally fail after 30-150 deep cycles if deep cycled, while they may last for thousands of cycles in normal starting use (2-5% discharge). Deep cycle batteries are designed to be discharged down as much as 80% time after time and have much thicker plates.

When should I charge my deep cycle battery?

Batteries should be fully charged after each use. “Use” is defined as 30 minutes or more of runtime. Before charging, make sure the charger is set to the appropriate program for deep cycle flooded/wet, AGM, or Gel batteries. Charging time will vary depending on battery size, charger output, and depth of discharge.

How many solar panels does it take to charge a 100ah battery?

If you refer to the calculation below, of ‘how many solar panels do I need’, we use the example of a 100Ah 12 volt battery. With 6 hours of sunlight that we estimate we get in the day, and by overrating the solar system by 20%, we estimate we will need 240 Watts total power.

How long will a deep cycle battery run a TV?

Well, the 12v tv I have in my caravan runs at 3 amps (36 watts). So on a 120 amp hour AGM (deep cycle) battery, using only 50% of that (the safe discharge limit for deep cycle lead acid batteries), it will run for about 20 hours.

Is it safe to charge a deep cycle battery indoors?

Not “safe” without extra care. Death unlikely but likely possible if you “just do it”. Discharge will not release ‘fumes’ in general use. Risk from “gassing” (Gargoyle knows) can be kept small but not zero when charging with a panel of that relative size.

Should you charge a new deep cycle battery?

New batteries should be given a full charge before use. New deep cycle batteries need to be cycled several times before reaching full capacity (50 – 125 cycles, depending on type). … Batteries should always be watered after charging unless plates are exposed before charging.

How long will a 100ah deep cycle battery last?

1000 hoursA very small user of power is a 1.2 watt LED light running on a 12 volt power source will use 1.2W / 12V = 0.1 amps. Therefore a 100ah (amp hour) battery will last for 1000 hours.

Can you overcharge a deep cycle battery?

Both overcharging and undercharging will have serious adverse effects on the lifespan of a deep cycle battery. In particular, you can seriously shorten the lifespan of a battery if it is used in a deep cycle application that it was not designed for.
