Cavalier Battery

Yeah, everybody jumps on the Cavalier threads.

If your charger doesn't have a cut off, you could be over charging it.

If they use the sprayer very often, they're probably killing the battery with constant cycling.

Get one of these.

The only charger recommended for extended or a storage application is the 1.5 amp 12-volt charger specifically designed for long term, slow trickle charging/maintenance applications.

It is a deep cycle. The charger is off most of the time.

I don't think there is a good answer.

You're using a deep cycle car battery?

Don't put a deep cycle in your car.

How long between uses?

12. HOW CAN I REVIVE A SULFATED BATTERY?

Lead sulfation occurs when a lead sulfate compound is deposited on the lead electrodes of a storage battery; this is a problem if the lead sulfate compound cannot be converted back into charged material and is created when discharged batteries stand for a long time. When the state-of-charge drops below 80%, the plates become coated with a hard and dense layer of lead sulfate, which fill up the pores. The positive plates will be light brown and the negative plates will be dull off-white. Over time, the battery loses capacity and cannot be recharged.

12.1. Light Sulfation

Apply a constant current from one to two amps for 48 to 120 hours at 14.4 VDC, depending on the electrolyte temperature and capacity of the battery. Cycle (discharge to 50% and recharge) the battery a couple of times and test capacity. You might have to increase the voltage in order to break down the hard lead sulfate crystals. If the battery gets above 110° F (43.3° C) then stop charging and allow the battery to cool down before continuing.

12.2. Heavy Sulfation

Replace the electrolyte with distilled water, let stand for one hour, apply a constant current of four amps at 13.8 VDC until there is no additional rise in specific gravity. Remove the old electrolyte, wash the sediment out, replace with fresh electrolyte, and recharge. If the specific gravity exceeds 1.300, then remove the old electrolyte, wash the sediment out, and start over with distilled water. If the battery electrolyte rises above 110° F (43.3° C), then stop charging and allow the battery to cool down before continuing. Cycle (discharge to 50% and recharge) the battery a couple of times and test capacity. The sulfate crystals are more soluble in distilled water than in electrolyte. As they are dissolved, the sulfate is converted back into sulfuric acid and the specific gravity rises. These techniques will only work with some batteries.

Even responding to a "Cavalier' thread must sap your intelligence.

It isn't in my car. It's at work, on the charger.

It's your thread.

We have this sprayer at work that is powered by a big 12 V car battery.

Sounds like one of those guys you're always picking on came to your house and hit you in the head.

No information. What kind of battery, what kind of charger. I have no idea what the lights in the shop being off have to do with it......................yikes.

OMG! Why are you so difficult?

OK, it's a 12 V deep cycle boat battery.

The question is, is leaving a lead acid battery, any lead acid battery, on the charger all the time bad for the battery? If the charger is off most of the time.

It's mostly academic anyway.

Are you taking night classes?

Is this homework?

The question could be answered with a quick, simple test; put an ammeter in line with one of the charger leads with the charger off, and see if the charger presents any kind of load when it's not powered.

Wow, why didn't I think of that.

That's a good answer if ever I saw one.

I have just the meter for this.

How cavalier is this battery? It can't be too cavalier if it has some worries.

I think the problem is mental, it's discharging you mentally...but the battery will be fine...

What we have here is failure to communicate.

I will not tax my brain over this dilemma any more. The battery will remain on the charger.

Anyway, I have a Christmas tree to worry about. _{Figure that one out smarty!}

I'd get one of those 1.5 amp trickle chargers. It's always on, and only charges when the battery voltage drops below a certain point.

In storage, your battery will slowly discharge whether it's hooked up to your existing charger or not.

It would depend on the type of battery charger.

My generator battery charger (my genny system is a hodge podge of components I put together) has a DPDT relay incorporated into the circuit board (charger purchased from Auto Zone) that disconnects the 12V DC cables (to battery) from the rest of the charger circuit.

In any case, IMHO I think the battery discharge rate as a result of remaining connected for long periods would be negligible.

I am thinking the diodes in the charger circuitry would prevent discharge _{but there I go thinking again}

Happy Holidays!

I am pleased to report that LynDoor™ Labs has perfected SuperVelocity Electron Filtering. The SEF device captures all the electrons from any source (in this case, your battery charger) and compresses them. These compressed electrons can be used on demand. However, the SuperVelocity Electrons are unusable in this form due to orbital overlapping.

By discharging the SuperVelocity Electrons (via the Unobtanium nozzle array) through a number of feather cannonballs, the velocity is reduced sufficiently to be once again useful; the electron filtering is accomplished during this deceleration.

The beauty of the device (and the reason we are sending you a beta device) is, the LynDoor™ SuperVelocity Electron Filter acts as a check valve, ensuring the electron supply source (in this case, your battery charger) shall NEVER see those little rascals again. Thus, your concern over incidental electron discharge can be put to rest. As a bonus, the filtered electrons are perfectly suited for ornamental lights, such as you might find on a christmas tree.

For some reason, the device is not operational at night. Sadly, in the southern hemisphere there is another problem: it runs backwards... we are still working on that.

Finally, another sane answer.

I look forward to acquiring another cutting edge tool from the team of genii at LynDoor™ Industries where tomorrow's dreams are today's reality.

We currently have 250 strings of lights on our downtown trees. Will one SEF be sufficient to power all of them, and can I get a credit from the utility for the excess, unused power generated?

The LynDoor™ SEF boasts an efficiency of nearly 12%. This efficiency is accomplished through the utilization of a number of 'take-off' components (thus we can claim to be greening the environment). The components are a mixed bag of vacuum tubes from decommissioned Bulgarian Air Force radar sites, ice-cube relays from Argentine submarine hunter ships, some unknown but interesting parts from old Russian reconnissance satellites, and the PC boards from the LynDoor™ WattSucker G6. Each 1200 watt device produces about 2,400 BTU per hour, which is a splendid byproduct if you ask me.

You have not advised the power consumption of the strings of lights involved. I would hazard a guess that one SEF device per string of lights should about do it. As a principal, you will certainly be granted the quantity required at no expense, unless somehow our stockholders hear about this.

"... excess, unused power generated?" What is unused power?

LynDoor™ Industries, the voice of reason from the wilderness. Offering ridiculous solutions to easy problems for nearly one year.

Is this a test? If it is a cheap charger (just transformer and diode) it probably won't discharge the battery. If it is a high end charger with different sense and charge levels, it may discharge the battery.

If it were me I would have it connected to a turbo encabulator and free air compressor. Let the battery discharge to 50%. Then use the free air to power the turbo encabulator which in turn charges the battery.

As an alternative you can connect the battery to an HHO system, use the HH to power an HoD sprayer. The extra HHO can be used to power a fuel cell to provide power to the grid.

The latter is probably a better choice, if your company has a good grant writer, she/he can probably turn this into substantial green buckos.

Currently, we use ten of these on each rear wheel of our golf carts to charge the batteries while we're driving to the site.

The turbo encabulator is still protected by "intellectual" property rights. These property rights are currently owned by Peggy, who also does the commercials for a cell phone company on TV. Talk about a shrewd investor!!

Peggy

That's him. True visionary.............................

umm

I'm telling

you responded to an AP

It's getting close to Christmas.
