How long will a 100ah battery run a fridge?
1000 hoursTherefore a 100ah (amp hour) battery will last for 1000 hours.
A slightly different example is a 60 watt fridge running on a 12 volt power source uses 60 /12 = 5 amps, but only while the motor runs..
How low can you run AGM batteries?
You can accept shorter runtime. And even if you don’t discharge your battery at all, it won’t last forever. For most applications the best trade-off is to try to limit discharge to less than 50%.
Can I use a trickle charger on an AGM battery?
You can use your regular battery charger on AGM or gel cell batteries. False. These batteries like to be charged slow and low. Many AGM/gel cell battery chargers have microprocessors that collect information from the battery and adjust the current and voltage accordingly.
How low can I discharge a AGM deep cycle battery?
The leading advantages of AGM are a charge that is up to five times faster than the flooded version, and the ability to deep cycle. AGM offers a depth-of-discharge of 80 percent; the flooded, on the other hand, is specified at 50 percent DoD to attain the same cycle life.
Are AGM batteries worth the extra money?
Definitely worth the price. The biggest perk is they hold their charge. You can charge it in the fall, come spring it’s still 100% charged. I know mine has lasted quite a bit longer than my old lead batteries…that said, I never spent the money on lead then I now do on AGMS.
What voltage is too low for a 12 volt battery?
12.4 voltsWhen any 12-volt battery is discharged below 12.4 volts, sulfation begins to occur within the battery. Over time, this sulfation will diminish both the performance and lifespan of the battery. Regular use of a quality battery maintainer will keep batteries properly charged and extend their useful life.
Is 11.9 volts enough to start a car?
A flat battery can show 12 volts , but not be good enough to start a car . … 11.9v indicates the battery is completely discharged. Anything under 12.2v means the battery is in a state of discharge, and a healthy battery should show 12.6v in a static state. Yours needs to be replaced.
How long should a 12 volt battery hold its charge?
The actual resting voltage, or the voltage a battery will settle at 12-24 hours after being removed from the charger, is closer to 2.1 volts per cell, or about 6.4 volts for a 6v battery, and 12.7 volts for a 12v battery. These numbers assume 100% healthy cells, and may vary a bit lower for older batteries.
How do I know if my 12 volt battery is bad?
There are some sure ways you can tell if your battery is bad by simply taking a good look. There are a few things to inspect, such as: a broken terminal, bulge or bump in the case, crack or rupture of the case, excessive leaking, and discoloration. Broken or loose terminals are dangerous, and can cause a short circuit.
Will 10 volts start a car?
A: Car battery voltage will change depending on its condition. When the engine is off the battery open circuit voltage is 12.9 volts. … As the battery discharges the voltage will sag down to 10 volts or lower. If the battery stays above 11.8 volts it will generally still start the vehicle.
Is 12.2 volts enough to start a car?
12.2v is enough to start the car. It’s a 12v battery after all, it’s just voltage settling after being at ~14v when driving.
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.
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.
How do I know if my 12v battery is charged?
When the battery is not being charged and not delivering charge to a load, this is the rule of thumb. For a 12 volt, leadacid battery, the voltage measured between these two points should be between 11 and 13 volts. The closer the voltage is to 13 volts, the closer the battery is to being fully charged.
Is it better to charge a battery at 2 amps or 10 amps?
It is best to slow charge the battery. Slow charging rates vary depending on the battery’s type and capacity. However, when charging an automotive battery, 10 amps or less is considered a slow charge, while 20 amps or above is generally considered a fast charge.
How many years will a deep cycle battery 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 lowest voltage for a deep cycle battery?
10.5 voltsThe lowest limit is 10.5 volts (used in testing) and obviously unsatisfactory in practical use. Experienced RVers try to use no more than 20% to 50% of the energy available in a battery before recharging. That means they never let resting voltage get below 12.5.
How many volts should a deep cycle battery have?
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.
Is 12.7 volts enough to start a car?
The Minimum Voltage Range To Start a Car In general, while both the engine and the generator are in the working state, the voltage of the battery should be within 13.7 – 14.2V. … In the standard state, a fully charged battery should show a 12.6-12.7V.
Can you overcharge a deep cycle battery?
Overcharging Deep Cycle Batteries: As a result of too high a charge voltage excessive current will flow into the battery, after reaching full charge, causing decomposition of water in the electrolyte and premature aging. At high rates of overcharge a battery will progressively heat up.
