Title: batteries plus again/im confused Post by thumperclone on 06/23/08 at 07:19:56 well my second batteries plus agm battery died after a week(first one lasted about the same)..luckily we had just pulled into durango and was able to find a suzi shop.. bad batch from B.P. ? i was playing my stereo(3 amp load) with the engine off for less than ten minutes..handle bar mounted volt meter shows charging at idle and above..the ls (mine)wont run with a dead battery..we jumped it off got running but couldnt get above 2k rpm w/o cutting out??new battery in, made it back to farmington and yesterday back home.. so i learned dont run the stereo with the engine off tho my math tells me i should be able to for an hour and still have enuff reserve for starting..i dont get it... |

Title: Re: batteries plus again/im confused Post by verslagen1 on 06/23/08 at 09:06:04 2k must be where the charging circuit cuts in. did you charge it or replace it? work ok after? |

Title: Re: batteries plus again/im confused Post by thumperclone on 06/23/08 at 11:34:37 replaced w/ what the suzi dealer had this is my second BP agm in a month will put on charger while home 4 lunch and will see after work .got a digi tech get two green lights on led volt meter a 1240 rpm so have set idle there any lower or higher rpms only one green light..vm range = 2 reds 8> 10 v,2 ambers 10 >12 v,2 green 13 >14v,one red over 15v bad batch from BP ???any ever heard such??? |

Title: Re: batteries plus again/im confused Post by verslagen1 on 06/23/08 at 11:49:27 Sure sh it happens but you're also the only one that it happens to with stereo accompaniment. ;D |

Title: Re: batteries plus again/im confused Post by thumperclone on 06/23/08 at 11:53:19 ;D thanks needed the humor!! ;) just got in from the garage put on the charger gauge shows fully charged..battery DEAD 3 volts..same as last week...deka agm is what i ended up with |

Title: Re: batteries plus again/im confused Post by verslagen1 on 06/23/08 at 12:04:46 I'ma big crank myself. ;D |

Title: Re: batteries plus again/im confused Post by demin on 06/23/08 at 14:37:49 Yep same battery.I'm not real crazy about mine in the '86 either.The one from Wally World in the '87 seems better,and for 25 bucks.The '86 with the turn signals flashing,and my brake lights on,my headlight flashes,too.Even if I'm at speed(higher rpm's)bad! |

Title: Re: batteries plus again/im confused Post by Bleemus on 06/23/08 at 14:45:19 I am no expert so take this for what it is worth. Listen to Verslagen and others before me. The home charging sounds like something a friend of mine had happen. Big amp draw from the charger and the battery was dead soon after. I asked him to start charging it again when I got there and he had reversed the polarity each time so basically the battery was toast. You seem smarter than that but worth mentioning. Red is positive, black is negative. ;) According to another friend who works at a dealership he has never in 20 years seen a battery arrive from a supplier bad so that would be a long shot. Might happen I suppose but I would look elsewhere for the cause. |

The bigcrank pair in the '95 and '02 seem to be solid - no flickers unless the idle is too low - no self discharge that I can tell |

Title: Re: batteries plus again/im confused Post by verslagen1 on 06/23/08 at 15:08:05 Mine's been in there since Dec. 10k miles turns over strong, not a hint of slowing the couple of hard starts I've had. Ride nearly every day. ;D |

Title: Re: batteries plus again/im confused Post by Reelthing on 06/23/08 at 15:13:26 might be worth a volt meter when those 86/87 bikes are running - I read something the agm are happier with a higher volt charge - see If I can find that article |

Title: Re: batteries plus again/im confused Post by thumperclone on 06/23/08 at 17:39:51 shes due for the 11k service any who so will do the generator no- load performance and ac generator continuity tests..would think charging output would be all thats necessary..14-15.5 vdc @ 5k rpm across the battery....my led handlebar mounted volt meter shows that much. guess bike work saturday and fishin sunday |

Title: Re: batteries plus again/im confused Post by T Mack 1 on 06/23/08 at 18:08:28 Hmmmmm ... would be nice if you could get both a voltmeter and an Ammeter..... |

Title: Re: batteries plus again/im confused Post by Max_Morley on 06/24/08 at 09:14:07 Here is an old FoMoCo rule of thumb and battery charging quick test. Using a DVOM (DigitalVoltOhmMeter) or at least DVM. Open circuit =no load = key off, battery voltage on a stabilized battery (off charger or vehicle operation) long enough to lose surface charge should be 12.6 V (6 cells x 2.1 V per cell) After 2 minutes in operation voltage needs to raise to 13.5 - 14.5 volts to push electrons into the battery to recharge it. Maybe slightly lower at first run but should stabilize there. GM says less than 12.4V OC (about 80% charged) and battery needs recharging before testing. If you have only 10.5 volts (or some multiple of the 2.1V bit) then one(or more) cell(s) is(are) bad. Once a battery has sat in a completely discharged state very long it is difficult to recharge it and it's cranking ability is damaged. In my experience about 2 tirmes dead flat and the battery is junk. Max |

Title: Re: batteries plus again/im confused Post by gj859 on 06/24/08 at 10:13:35 I caught a 4lb 12oz smallmouth on rainy lake, which is on the Mn. can. border about 4 years ago. I don't know which is more fun, riding my savage or catching smallmouth, so I do both every chance I get. |

Title: Re: batteries plus again/im confused Post by Max_Morley on 06/24/08 at 12:21:21 Ammeter goes in between the battery cable and battery post on either terminal with polarity respect. Be sure and measure the voltage at the post or as close to it as possible as the ammeter usually has a shunt in it and a couple 10ths V could be lost there at full rated output. Clamp on inductive work easier but is much more expensive. |

Title: Re: batteries plus again/im confused Post by Charon on 06/24/08 at 12:59:49 In automotive use the ammeter usually goes in series with everything EXCEPT THE STARTER. It might be a trick to find a place to do that. Starters usually pull enough current to damage the ammeter, though that might not be true on a motorcycle. Start by making sure the battery is fully charged. Be careful if you are using a "smart" charger, as it might see a dead battery as a defective battery and refuse to charge. Get a charger rated at two amps, and charge the battery overnight. Visual check: A two-amp charge into a fully charged battery should result in at least a few bubbles coming up through the acid. This only works in a standard battery, where you can see the acid. If you put a meter on the battery at the end of charge, you should see about 14.4 to 15 volts, depending on the charger. (Edit to add: A "smart" charger, such as a Battery Tender, may have gone into float charge mode, and show about 13.6 or so.) Then let it sit for half an hour, and measure the voltage with a digital meter. You want to see about 12.6 volts. As an alternate, put it in the bike and see if it will light the headlight. If it won't it's probably shot. Having charged the battery and put in in the bike, start the bike and watch that digital meter. It ought to drop a little during the start, then come back up. At idle the meter may show a little below, or a little above, the 12.6 volts. When you rev the engine (it doesn't have to scream) the voltage should start to rise, and after a few minutes should settle about 14 volts. You will see published numbers anywhere from about 13.8 to 15 volts. If you get from 14 to 14.4 you are probably OK. Under 13.6, little or no charge. Over 15, overcharge. The voltage regulator has to bring the system voltage up over the battery voltage in order to force current back into the battery, thus charging it. |

Title: Re: batteries plus again/im confused Post by drharveys on 06/24/08 at 13:04:51 AGM batteries, gel batteries and any other new technology batteries are very sensitive as to how they are charged. Push too many electrons through them too fast and they are toast! You can't use a regular automotive type charger with them, and in the smaller sizes used in bikes I'd still be suspicious of even a more sophisticated car charger. Best bet: Battery Tender Junior. Don't forget the Junior part. It's low powered enough not to cook an AGM battery, and has the right "float" to make the battery think it's being charged by a bike! |
