# What should 8v battery read?

## What should 8v battery read?

Healthy batteries will indicate about 50 to 52 volts on the voltmeter. Most battery packs hold around 48 volts. Keep in mind that the high number doesn’t mean that the batteries are instantly good.

## What should be specific gravity of battery?

from 1.280 to 1.300
The specific gravity of the electrolyte in a fully charged cell should be from 1.280 to 1.300. If it varies more than 10 points above or below these values, adjust it by drawing off some of the electrolyte with a hydrometer and adding water to lower the gravity, or 1.400 acid to raise the gravity.

What to do if specific gravity of battery is low?

When the specific gravity of the battery gest low, the best remedy is to increase the concentration of its electrolyte. Increasing the specific gravity of the battery will also increase the potency of its electrolyte for better performance.

How many volts should a fully charged 48 volt golf cart have?

The target voltage for a 48 volt charger for AGM or some flooded batteries is 2.4 to 2.45 volts per cell, which is 57.6 to 58.8 volts.

### When should you check specific gravity of a battery?

The most accurate and direct way to test the state of charge of a battery cell is to determine the specific gravity of the battery electrolyte. The higher the specific gravity of the electrolyte the higher the state of charge….Temperature Correction.

Charged Specific Gravity
50% 1.180-1.200
25% 1.155-1.165
0% 1.110-1.130

### What is the specific gravity of a 6 volt battery?

12 volt – 6 volt Battery Maintenance & Charging Guide

State of Charge Specific Gravity Voltage
6V
100% 1.265 6.3
75% 1.225 6.2
50% 1.190 6.1

How long do 8 volt golf cart batteries last?

between five and ten years
When you take care of your golf cart’s battery, you can expect it to last anywhere between five and ten years.

How accurate is a battery hydrometer?

Freas hydrometers are guaranteed to remain accurate throughout the entire life of the instrument. The ‘basic’ Freas No. 1 battery hydrometer measures specific gravity from 1.250–1.275 graduated in 0.002 degree.

#### What is the full charge of 48V battery?

48V LiFePO4 Battery Voltage Chart 48V is more popular for larger solar systems. They rarely make sense for small-scale projects. They are fully charged at 58.4 volts and fully discharged at 40 volts. They are made by connecting 16 3.2V LiFePO4 cells in series.

Can I charge 8v battery with 12v charger?

As for a 12v charger on an 8v battery I can say that it sometimes can work to spot charge part way, but if you use a DUMB 12v battery charger you may repeat what I did blowing a lead off the charger. Even at 2amp usually you will drastically short out a 12v dumb charger and potentially damage the charger.

Will a 6 volt generator charge a 8 volt battery?

Depends on what it goes in. If the machine has an actual voltage regulator, it needs to be adjusted to charge an 8 volt battery. A 6 volt battery needs 7.4 volts to charge, an 8 volt battery needs the generator to put out about 9.5 volts to charge.

## What should a fully charged 6 volt battery read?

A 6V battery is actually fully charged when it reads slightly over 6V on a multimeter. A 6 volt charger is typically designed to produce about 7 volts so that it can attain a full charge.

## Can you overcharge batteries in a golf cart?

Overcharging your golf cart batteries may damage them. It is best to use an automatic charger that turns itself off when a battery is fully charged. Some older models lack this important feature. If you must use a manual charger, don’t forget to turn it off.

How long do Trojan 8 volt batteries last?

According to the team at Golf Carts Plus, the short answer is 7 – 9 years. However, to achieve that you need to carry out the routine maintenance and watering of your battery.

How much variance is acceptable in battery cell readings with a hydrometer?

A fully charged battery with well mixed electrolyte should show hydrometer reading on all cells to be within 25 points of each other. If a discrepancy greater than this persists after an equalizing (extended) charge, the battery should be checked by an experienced battery technician.

### What is the specific gravity of a battery?

The specific gravity decreases during the discharging of a battery to a value near that of pure water and it increases during a recharge. The battery is considered fully charged when specific gravity reaches it’s highest possible value.

### Are there any 8 volt deep cycle batteries?

8 Volt Deep Cycle Batteries | U.S. Battery Mfg. Co. U.S. Battery’s 8 volt deep cycle batteries are trusted around the world. We offer a full line of 8 volt flooded lead acid and AGM batteries.

What is the specific gravity of an electrolyte?

One of the key parameters of battery operation is the specific gravity of the electrolyte. Specific gravity is the ratio of the weight of a solution to the weight of an equal volume of water at a specified temperature. Specific gravity is used as an indicator of the state of charge of a cell or battery.

How do you calculate specific gravity from voltage?

Specific gravity = cell open-circuit voltage – 0.845 Cell open circuit voltage = specific gravity + 0.845. The above equations permit electrical monitoring of approximate specific gravity on an occasional basis. As mentioned earlier, specific gravity measurements cannot be taken on sealed lead-acid batteries.
