Question: Do I Need A Special Charger For Deep Cycle Battery?

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 should a fully charged 12v deep cycle battery read?

Voltage on a fully charged battery will read 2.12 to 2.15 volts per cell, or 12.7 volts for a 12 volt battery. At 50% the reading will be 2.03 VPC (Volts Per Cell), and at 0% will be 1.75 VPC or less. Specific gravity will be about 1.265 for a fully charged cell, and 1.13 or less for a totally discharged cell.

Can I use a trickle charger on a Optima battery?

Can you trickle-charge an OPTIMA battery? … Yes, and you can use any charger on an OPTIMA battery as long as the voltage is regulated properly. If your charger will remain on indefinitely, the voltage should be at 13.8 volts maximum with a one-amp maximum current.

Are Optima Batteries worth it?

How long should you charge a deep cycle battery?

The time it takes to properly charge a battery depends on its current discharge value and your charger’s amperage specification. A charger with 15 amps, for instance, will take about two hours to fully charge a battery at a 25-percent discharge value.

How many solar panels does it take to charge a deep cycle battery?

Charging your battery at 12 volts and 20 amps will take five hours to charge a 100 amp hour battery. By multiplying 20 amps by 12 volts, 240 watts is how big of a panel you would need, so we’d recommend using a 300w solar panel or 3 100 watt solar panels.

What amp should I charge my deep cycle battery?

Considering you have a healthy battery and the battery is completely discharged: For round numbers takes a 150 amp deep cycle battery. Charge it at 10 amps, you will need to charge that battery for up to 15 hours to fully charge as it puts up to 10 amps in each hour.

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.

How long will a deep cycle battery stay charged?

For example, if you have an 80-ampere-hour rated battery, then a load of four amps would discharge the battery in approximately 20 hours (or 16 hours down to the 20% level). New batteries can take up to 50 charge/discharge cycles before they reach their rated capacity.
