Let's talk batteries

Like the guy at the Deka battery store said, not just yet, :nea: but more than likely in the future, because of the weight factor,if nothing else. :good: At the present time A G M's are the best bet in his opinion, & mine so far, they don't have the bad tendency of BLOWING UP . :yes: Gave me good advice over 10+ years ago when he told me to spend the extra money, & buy the A G M battery. :whistling:

+1 on AGMs :good:

well as said by V ....moving the sense wire to battery cut the bike wiring out ...so far ive had no trouble at all with the battery what so ever being over charged....it seems many things could be done to lower charge voltage a bit .....like a ballast an ignition would use maybe ...but also eric bike been around awhile and ive heard no battery problems out of him at all ...there is plenty of good reason to pioneer something better than the norm in my experiences ....

No argument, :nea: the set up puts out WAY more current than is needed, to run everything. :doh:

Going by memory. I shouldn't do that. Saying numbers and not multiplying them. I shouldn't do that either. The 14.4v was the maximum charge rate. Resting rate should be 13.2- 13.7v.

This is from my battery maker :

Congratulations on your purchase of a Ballistic Performance Components EVO2 Battery! Your new battery comes charged and is ready to install. EVO2 batteries are very different in chemistry, construction, and behavior than a traditional lead-acid battery. Here are somethings to consider while using your EVO2 battery:
Maximum Voltage: 14.4 volts
Minimum Charged Voltage: 13.2 volts
Charged Resting Voltage: 13.2 volts – 13.7 volts.
Minimum Voltage: 9 volts
Standard Charge Rate Specifications: 2amps @ 13.2 volts until the battery reaches a maximum voltage of 14.4 volts

I'm pretty sure mine charges above 14.4 at speed. So a long trip and I might have trouble. I have another multimeter. A cheapie from Harbor Freightb, but tomorrow I'll check it with that.

All three of my 1200's, charge right at the upper limit,14.9 - 15.01. Anything over 15 is too much, :read: but .01 on a H. F. meter, isn't over enough to worry about, :nea: if so then they all need replaced. :headscratch:

The 2amps charge rate would be my main issue.

Any idea how many amps a Wing charges at?

There is no actual regulation in amperage to the battery, only the voltage. The battery will take what it can/needs in amperage to recharge. This is considering the use of a conventional battery.

An 1100 is 25 amps at 5000 rpms

+1 minus any load to run the systems being used. If the battery was heavily discharged it will take all available amps left from the charging circuit.

Read somewhere, most m/c battery's are rated at 18 volts, the Deka's A G M's are rated at 20v. Charge rate not to exceed 10% of voltage rating, or 1.8v, or 2.0v, battery tender is 1.25v, my Schumacher is 2.0v, the maximum for m/c battery's.

 

[joedrum]

where dose he get all this info :shock:

 

[Denver]

Read up on these A G M's back in 03 when i first found out about them. :read: Believe if you dig into this you will come up with same answer's, for A G M"S, & flooded battery's. :yes: Lithium is a different animal entirely, lighter, takes, & holds a charge, quicker,& longer than old type's, lots of things to like. :clapping:

18 and 20 volts is wrong unless you want to kill them.

I think I'm going to try and find a different regulator. Mine scares me a little it keeps at the upper 14's. When I shut it down it drops slowly to 14.2. Overnight still 14.1. Turn the ignition on with the headlight for 3 seconds and it drops to 13.2?? And stays there. Maybe I need to shut it down and leave the headlight on ten seconds to keep it below the scary voltage. I compared my multimeters and they are within a tenth. There are vids out there of them catching on fire from continuous overcharge. It's been two years plus, but I don't think I've ridden over two hours straight. Probably worrying about nothing, but if the regulator failed, what could happen?

 

[slabghost]

I've read they explode if over charged. I've seen the lead acid batteries explode during heavy charging too. My personal plan is to move the reg. sense wire to the battery like Joe did.

 

[ekvh]

YouTube has few vids, but they usually burst the cover/case and smoke a bunch before igniting. They don't really explode from what I've seen. It probably takes certain circumstances for that to happen. Chances are that ignition components would get taken out before a flame up. That's my gut talking, no science to back it up.

Dan, 1.8volts, & 2.0volts, to charge, at 10% of total battery voltage! 18 & 20 volts what the battery is rated at, how they figure this don't know.

The batteries are not rated at 18 and 20 volts.

This reference is from batteryuniversity.com.

The nominal voltage of lead acid is 2.00 volts per cell, however when measuring the open circuit voltage; the voltage of a charged battery should be 2.10V/cell. Keeping lead acid much below 2.10V/cell will cause the buildup of sulfation. While on float charge lead acid measures about 2.25V/cell; higher during normal charge.

Higher during normal charge doesn't mean 18 volts.

A 12 volt lead acid battery has 6 cells.
While on "float" charge, each cell is at 2.25 volts, multiply that by 6 cells in series= 13.5 volts.

18 & 20 amps are some kind of rating, on the battery's! :headscratch: Said before don't know exactly how it's figured, or where it came from. :nea: But 10%, is the maximum safe rate of charge. making 1.25, & 2.0, volts about right. :whistling: Maybe someone with more information as to nature the 18, & 20 volt readings will jump in, as that's all i can remember. :blush: That said, memory stores what it finds important, & drops the rest, right most the time, but not always. :smilie_happy:
