A way To Save Charging Time

Like I wrote earlier.... I asked Oyster, their guy didn't understand the boat. Was then referred to Fox's Marina which was zero help.

Both delivery captains hired five years ago in the UK couldn't figure it out.

Then hired an electrical engineer in Mallorca who turned out to be a complete boob. Then asked several other electrical engineers who basically saw that the system was 110v, then watched their eyes spin. I finally gave up after about the sixth or seventh guy.

Believe me I tried.

Next question: Is my voltmeter what I need to test the battery performance? If so, then how do I determine how many amps can be put into my apparently healthy house battery bank?

From your experience level there is only one thing you should buy right now and that is a Balmar Smart Gauge. Idiot proof and will give you the numbers you need. Not saying your an idiot but are electrically challenged at this point in your education.

Ken,

A hygrometer can tell if batteries are fully charged or not. A very accurate volt meter measuring right at the battery terminals can also measure charge after 24 hours with batteries disconnected. Go to the battery manufacturer web site and read what they say about specific gravity and voltage for determining charge percentage.

No amp-hour counting device can accurately measure charge level.

All lead acid batteries require several hours to charge to 100% no matter what size charger you have.

98% of what you read about batteries on the internet is wrong.

Is there any programing required? Will it tell me how many Ah are stored in my fully charged house battery bank without having to program it or determine or calculate a baseline total?

[Bleemus]

Lol. It will tell you accurate state of charge without programming or calibration. And the longer you use it the smarter it gets. Truly a wonderful piece of gear.

And it can be installed by a caveman!

Good, 'cause I just ordered one.

Thanks.

You obviously have internet access, why don't you get the instructions on how to program your battery monitor???????

I think a Smart Gauge is just another unneeded black box!

Here's the problem.... It's in German and no longer published in English.

I need something easy to use.

A voltmeter can help you in finding out a lot about your batteries, but just sticking one across the terminals will tell your very little. It really only becomes useful in diagnosing battery "performance" if you take multiple readings under various conditions (while charging, while discharging at various rates, after it has sat with no charge or discharge for many hours, etc, etc)

If so, then how do I determine how many amps can be put into my apparently healthy house battery bank?

Trojan recommend charging at a rate equivalent to 20% of battery Amp hour capacity, so 90 Amps would be a good number to work on. But of course, that will only be in bulk phase. Once you SOC goes up, you won't be able to put anywhere near that many Amps into the bank.

Bet you work at it you can find an English version, if not you should replace it as what good is it to have something like that on your boat

A hygrometer /haɪˈɡrɒmᵻtər/ is an instrument used for measuring the moisture content in the atmosphere. Humidity measurement instruments usually rely on measurements of some other quantity such as temperature, pressure, mass or a mechanical or electrical change in a substance as moisture is absorbed. By calibration and calculation, these measured quantities can lead to a measurement of humidity. Modern electronic devices use temperature of condensation (the dew point), or changes in electrical capacitance or resistance to measure humidity differences. The first crude hygrometer was invented by Leonardo da Vinci in 1480 and a more modern version was created by polymath Johann Heinrich Lambert in 1755.


HyDrometer:

https://en.wikipedia.org/wiki/Hydrometer
A hydrometer or areometer is an instrument that measures the specific gravity (relative density) of liquids—the ratio of the density of the liquid to the density of water.
A hydrometer is usually made of glass, and consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float upright. The liquid to test is poured into a tall container, often a graduated cylinder, and the hydrometer is gently lowered into the liquid until it floats freely. The point at which the surface of the liquid touches the stem of the hydrometer correlates to specific gravity. Hydrometers usually contain a scale inside the stem, so that the person using it can read specific gravity. A variety of scales exist for different contexts.
Hydrometers are calibrated for different uses, such as a lactometer for measuring the density (creaminess) of milk, a saccharometer for measuring the density of sugar in a liquid, or an alcoholometer for measuring higher levels of alcohol in spirits.
Principle Operation of the hydrometer is based on Archimedes' principle that a solid suspended in a fluid is buoyed by a force equal to the weight of the fluid displaced by the submerged part of the suspended solid. Thus, the lower the density of the substance, the farther the hydrometer sinks. Thus, it is based on the principle of floatation.

I typed in Dcc4000 manual and found an English one right off the bat, but I'm not doing the work for you in support of the greatest boat of all Oyster
