Has anyone used one of the new crystal cell technology batteries? They are very small in sizes, can be mounted in any direction, do not have a liquid, don't need to be trickle charged during non-use, and the cost is reasonable. Oh, and they come with a full 5 year warranty from the company-not pro-rated: www.hotrodbatteries.com Just doing some research and thought I'd throw this question out.
I got an Odyssey, There seem to be a lot of people on here who have used them, the main thing with those, is if you run it all the way down into the ground, you need the proper charger to bring them back without damage. they are just fine charging from the cars electrical system.
I have used the Dynabatt batteries from Performance Distributors for years. They really work !!! I do put them on a trickle charger all winter but they hold up all summer long w/ o charging.
I use one in my 350 Chevy powered MG and it works great when space is an issue. The HotRod Battery is $185 plus shipping. I went to my local Interstate store and got a more powerful one for about $100. Fits in the factory tool box.
I don't know if it applies to these batteries or not but a maintenance free battery like my optima, if it's run down then recharging is almost impossible. I've heard that you can hook it up in series with another good battery and then put a charge on the system. The good battery fools the charger that there is enough voltage to bring the system back up to charge. Or at least this is how it's supposed to work in theory. I definitely dig the compactness of these hot rod batteries.
the optimas seem to have gone to **** since production went to mexico, on the odysseys and other dry cell type batteries like them, you can bring them back fine, but you need the correct type of charger, they are voltage sensitive, they can take all the current you can throw at them, but if the charging voltage goes too high, like a lot of chargers, they are damaged. they also take a certain number of amps,depending on the model to bring them back 100 percent. a trickle charger won't bring them back from dead.
Lostforawhile, Shouldn't an AMP meter tell ya' if the battery is going down? Why would it go dead if it's being charged through the alternator unless you're using it on a race car?
Dynabatt's are great if you need to save on space. However, don't plan on using anything else other than running the car with these things (like fan, radio, headlights, etc) if you have electronic ignition. Most EI's require 11.5 volts or better to run. The Dynabatt cannot keep up with electronic stuff and an Electronic Ignition at the same time. After 20 miles or so your car will begin to run like ****. I recently bought a car with a Dynabatt and had lots of problems with it. If you dont put a tricke charger on it or run the car oevery other day, then the voltage drops on the little battery. Once they go dead, then adios...you're out $$$ on the Dynabatt.
This is true. I had to once on mine when the brake light stuck on and ran the battery all of the way down. The Battery Tender would not charge it until I added another charged battery into the comnnecting for a while and then it would accept a charge.
I meant if you run them completely down by accident, the odyssey is supposed to be able to be run totally down to nothing and back 400 times without damage. The other AGM batteries are probably the same, remember they are small, but there's a heck of a lot of battery packed in that thing. The old flooded batteries are on the way out, one of the old things I'll be glad to see go, no more leaks,corrosion, outg***ing, explosions, and they don't die if you run them down a few times by accident.
if your charging system is working right, you shouldn't have a problem, the car is supposed to run on the alternator most of the time, you just need enough battery reserve to be able to get stopped safely if the alternator dies. the battery's reason for being there is to start the car and help prevent spikes in the voltage from the charging system . Ive got an Odyssey PC625, i picked it by specs, with an alternator failure, it should give me about 45 minutes reserve with the basics , if your charging system is functioning, you shouldn't have a problem with an electronic ignition, the charging system voltage should always be higher then battery voltage, except if you have a generator at idle of course, should be around 13.5 to 14 volts, if it's lower, your battery isn't going to stay charged, and you've got a problem
i've never had a problem with a dyna-batt. i run elect. ign. radio,heater,. after the engine is fired the alt. runs things.
exactly, if the voltage is down to 11 something, there's a charging problem. even if it drops while idling with a generator, the electronic ignition will still function, I think my MSD box will still work down to ten volts or so, you just lose the multi spark
My dynabatt has worked great all summer, I read on the dynabatt web site that the batt doesn't like heat and being run down. So far it has always started my high compression engine with no problems. You can buy them on the internet for around $90.
Here is what the pirate4x4 has to say about optima (there is a lot of good tech in there) http://www.pirate4x4.com/forum/showthread.php?t=913442&referrerid=151139
they will work but you need to use the correct type of charger or they will be damaged or not come back 100 percent, as long as you use the right one, they are great, most agm batteries if the voltage goes much above 14 volts they are ruined, current isn't important as long as there's enough to charge it 100 percent , trickle chargers won't do it, i know my oddysey pc625 requires 7 amps in a voltage control charger. a lot of the people who ***** about the oddyseys never read the instructions about deep dischaging and how to properly recharge, I've been building my electrical system in my car and using mine as a power source, and it's been great
Hey guys, how about back to the original question. Hotrodbatteries.com. Damn, that thing is small and their add says the 5-1/8" long x3-1/4' wide and 6-1/2" high is supposed to start a 375 horse motor. I could completely hide one of those in the trunk of my project. Have any other people had experience with them?
Mine is an Odysee of the same deminsions, probably the same battery. Starts mine with no trouble and it is not s stock motor.
