Glow clip battery

Post  PV Pilot on Fri Oct 14, 2011 4:45 pm

I think someone on here posted this battery, but couldn't find the thread to give proper credit for the find.

http://www.portablepower.com/enersys_cyclon_0800-0004-p-233.html
I picked up one of these batterys and lemme tell ya. If you have a hard starter motor, try one of these. Rechargable sealed lead, continuous 500mah draw for 10 hrs, super duty battery. Had a project on the engine stand and for the last few days just could not get hardly a pop out of it. New d cells in the holder, cleaning contact points, motor teardown for problem check, (about 3 times), no fire whatsoever. Plugged in one of the Enersys cells and the VERY first rotation, it fired right off. Called and talked to the folks at Enersys about charge rates, and discharge rates just to be on the safe side.

2v 5 Amp hour sounds like a neat little power pack

How are you planning to recharge?....of all the boat loads of different chargers I have a can not think of one that will put out a low enough voltage

edit in they have some much larger 2v cells...real cool

Enersys says to charge them from 2.27v to a max of 2.45v. Right out of the package they read 2.19, which is more than sufficent. A reccommended charge rate of about .250mah. You can just go by the voltage readout for the volt setting. I took it a couple points above 2.27 then pulled it off. They are ready to go right out of the package, i just wanted to check it before i used it.

I use a Fma charger that auto adjust the charge rate up to what the user sets it at. I set mine at .250 mah, just because i had a idea that it wouldn't pull much of a charge. The Enersys guy said you can pound them up to a 4 amp charge, depending on the state of discharge.

That's a pretty resilient battery then IMO definately worth the money.

I use such a battery, but I had problems with many spark plugs because they were the 2 volt battery and spark plugs 1.5 volts took a vacation.
If using this fitting long cables at least 2 meters thick from the battery to the spark plugs.
This cable length'll give His difference in volts from 2 to 1.5 and has insurance does not spoil the spark plugs.
This happens when the battery is full charging of current and has power.

Yes because then some is lost as heat and it is safer to use I think younmeamt glow plug but English isn't your 1st laguage so it's fine lol.

Here, once again, I'm seeing confusion over the difference between amperage and voltage. Excessive voltage burns out glo's in short order. Amperage is a power source's ability to perform work like light glo's but will not destroy the glo.

1 1/2 volts may not "light" a glo unless the voltage has sufficent amperage as a car with 12 volts may not start a car unless it has sufficient amperage from the battery.

Until thiis is comprehended the mystery of voltage/ampererage will continue to confound.

Personally, I often measure these measure these factors with a Fluke Model 23 VOM which aslso measures electricl resistane and continuity.

I checked the ends of a Cox clip as well as the heavy duty clip with heavier gauge wire that Bernie offers and I was seeing about 1.75V. Used spade type of crimp connectors to make the connections. Those by themselves have significant reistance.

A regular D cell will light about 1/2 the coil length in the glow head, so there is already some resistance there. With this Enersys battery, it lights the whole length of the coil, it's not like looking at the sun when it is lit, but it is comparatively brighter. A weak d cell will light about 1/3 of the coil length, then, if you get a big wet load of fuel during starting it will snuff out that glow and just crackle as it tries to cook it off.

Ok. what I write is not testing but Ohm's law for those who know electronics.
I wrote in another post that my job is electronic engineer so I think I know more for.

He looked at the chart below to happen understandable.
R = resistance coil spark plugs.
P= power coil spark plugs.
These two items are standard with the manufacturer of the spark plug ok.

Ohm's Law shows the following this:
I = V / R
I = Coil current spark plugs.
V = volt battery(volt spark plugs)
R = resistance coil spark plugs.

The Ampere-law watts shows the following this:
P = VxI or P=RI^2
P = Power spark plugs
V = volt battery(volt spark plugs)
I^2 = Coil current spark plugs in square

Well Make the calculations with these laws and see that when we have more volts and thus more current to the coil of the spark plugs then the force of the coil of the spark plug is outside proper functioning and risk for power interruptions.

Ok I glow in the spark plugs be greater but may damage the interests of greater power than that specified by the manufacturer.
I hope you understand me Elijah.
Thanks all.
