Is there now a Fools' Day every three months?
I refuse to believe this.

I refuse to believe this.
That was 14.42 V with a failed Pb battery (internal short in one cell, apparently).
I dunno how this voltage regulator works, it being controlled (I think) by the bike's Motronic CPU (ECU). I just went out and started the bike and got a 13.81 V reading above 2500 engine rpm, with the new LiFePO4 battery installed, which, I believe, is insufficient to charge it. This was with a cold alternator (less than a minute after starting up) in a vehicle I know not to charge well until the electronics are warm.
I plan to do some more testing tomorrow morning, especially on the rest voltage (13.2 V with ignition, fuel pump and headlight working).
Meanwhile, I bought an IMax charger for it just in case....
Scorpion.
I checked the alternator output with a known-accurate digital VOM. 14.42 V max with a fully-charged LiFePO4 at 13.2 V.
We'll see. For the price, if it will get me through this season, it was worth it, considering the weight saving.
Uh, I forgot to thank you for the information; I found it very useful.
Thank you!
It says right on the ad you linked that they recommend the use of a ctek lithium charger
Their "tech" said otherwise. I'm sure they would like to sell you a charger that costs more than the battery it charges!
You're right about alternators' voltage regulation, but only partially so. My motorcycle -- not car -- puts out 14.4 V max at ~2500 engine rpm and is rated to produce 50 amps. 50 amps would be too much current for a lead-acid, so we'll see how this battery fares in service.
LiFePO4 batteries are not useful for cars or trucks (or snow machines, for that matter) because they do not work for crap when temperatures fall below 0 C. Cold makes their voltage drop below useful and may permanently damage them, especially over time, according their tech.
Since I never ride my bike when it's that cold, I'll take the battery indoors to keep it toasty till spring. That's the plan, anyway.
I bought it here. http://www.batterystuff.com/ba... I live very near Grants Pass, so I picked it up. The pickup price was $139. The internet price with "free" shipping is ten dollars higher.
It may have a charge controller. I talked to the folks there at length about charging. The bottom line is more than 14Volts and less than 15.0000!! with high amperage. Up to 60 amps was mentioned. Charging time is said to be about six minutes with the right charger. I was told for this battery size, a 6-amp charger for a car is OK as long as it does not exceed 14.9999 volts.
The battery is made in ROC. The importer/distributor is an individual who lives in Grants Pass, OR.
Caveat emptor.
My cycle needed a new battery. Major brand lead-acid replacements were ~$120, off brands less. But I found a lithium-iron with three times the cranking capacity and the same case size for $140. It also carried a three-year replacement guarantee, instead of a lead-acid's typical 6-month one, as cycles' vibration and lack of winter use kill L-As in a year, typically, And, a great benefit to cycles, it weighed ten pounds less, making a reduction in the total weight of the bike by ~2 per cent.
So far (two weeks) I have no complaints.
The will to live is very strong, stronger than rationalism. A panicked drowning person will try to climb on the shoulders of a would-be rescuer, not caring that this will kill both of them. RIP Java AND Yahoo!

Some years back, I used a small, local ISP. I once got an email from them including an attachment (.exe). Being on a linux box, I opened it, to find it was malware (and the message was SPAM -- someone had cracked their servers).
Do not use an ISP's email and don't even correspond with them. Pay them for their bits and be done with them.
If corporations are people as the US Supreme Court and former candidate for President Mitt Romney have said, then they are obviously people who can ignore laws and customs they don't like. If a human person were to use facial recognition on a widespread scale to follow the public movements of and to gain personal information about another individual, they would run afoul of several anti-stalking measures, at least.
Not so for our corporate ubermenschen

It was good for keeping up with changes for the various projects scattered around the web, but it's not a substitute for SourceForge.
Yep. I had to go to RPMfind.net or to tucows to get the source or SRPMs.
HELP!!!! I'm being held prisoner in /usr/games/lib!
