Dead OEM battery and now dead Odyssey

[Demongroover]

A car one? Just be very careful on how long you leave it connected But the question is, why does it have the problem and will cooking it with loads of amps permanently cure the problem? If not, send it back.

Indeed, hard to say definitely but I want to know 'why' this has happened as I don't want to be in the same position in six months time.

and discovered the battery was indead a rare faulty one!!

Not as rare as you'd believe.


The praise i read of odyssey batteries in in direct comparision of my actual experience.

Plus an optimate isn't any good on a discharged odyssey battery. It will not fully charge it. You need a high amp charger to "kick start" it.

Try reading the instructions that come with the battery

I dont think the issue here is about a discharged battery as you suggest
its seems there maybe a problem with it reading fit for propose on a multimeter or fully charged on various charger units! and then not providing its charge when necessary. If there is a fault with the battery maybe perhaps "kick starting" would be impossible anyway!! plus Ive never seen the part in the instruction manual stating facts and procedures How to charge a faulty battery!

As i suggest


I was replying to other peoples suggestions about using their optimate battery chargers on odyssey batteries.

Plus i see fecked odyssey batteries at leat every fortnight. Which i also alluded to in my post.

There, spelt out in a nice clear statement as the previous one obviously went straight over your head.

Ohh thanks for your help!

Relaxed about Optimates... They seem to work fine for me and always have... but so does the oil, the tyres, the panniers, the exhaust, the headers, the Autocom, the seat and, not least, the tax disk holder.... Maybe I am just lucky?

I do though have a leak in my bathroom and my garage door has been done in

Like wise ..... I've had no issues with my 06 GSA which is still on the original battery and gets left on an Optimate when not in use.

My bathroom is fine and my garage door is being replaced next week

Indeed, I thought that was the purpose of the Optimate / Oximiser battery chargers. They also state the can be used on GEL or AGM batteries.
If they can't recognise a flat battery and rejuvenate it, but show that it is fully charged then what is the average trusting punter to do?
Maybe I didn't need an Oddyssey in the first place, just a better charger for my BMW OE battery

I've had the Odyssey on the Optimate till fully charged and the battery functioned ok for a few days - turning the engine over with gusto. Its only after sitting for 3 or 4 days without starting that the battery fails. I'm finding it increasingly hard to believe that the battery is at fault and rather something draining current. Maybe the problem's always been there but I bought the bike in May last year and rode it every day, but with winter riding being infrequent it loses charge quickly.

Having said all that - I have owned two Aprilias which are renowned for electrical faults and both made it through winter without so much as a bettery discharge. Or perhaps BMW's are a seasonal breed

DO like the diagram below with a DECENT multimeter and what result do you get?

Be careful You need a Meter with an Amps setting

Switch on the ignition BUT Do not hit the starter button what is the reading (If you have a lights always on model just disconnect the dip bulb for 5 mins)

This set up will show you if you have a current draw on your bike

After 5 mins with the key in the off position it should drop to 0.02 (or very bloody close to) amps!

So what does it say?

Could you use a 12v light bulb in place of the multimeter? Might be cheaper than frying your nice expensive fluke

My odyssey doesn't like being left over the weekend if I do this the charging system isn't enough to get it back up to 100% and it goes flat even when riding a significant distance.

If I charge it again from mains and run it daily, it will keep 100% fine.

Erm, I guess that means at a certain point of charge it will no longer charge.

I guess it's fecked. Nearly.

Nope You are assuming that the batery is at fault! When there could be other reasons

In reality You need to check that something is not drawing continuous current for some reason and are you using an optimate on the odyssey?

school daze

volts jolts & amps cranks,i think thats what my physics teacher used to say (apart from wake up edwards) thats why 12volts alone cant guarentee your engine will spin over and start.

Odyssey battery dead again.
Been sat without Optimate for 1 week to see whther it would lose any charge.
12.2v on the voltmeter.
Must say, I'm not impressed with these Odyssey batteries.

A stab in the dark here, but it was probabally dead the first time it got fully discharged. You're just trying to flog a dead horse now.

Here's a decent site explaining why I think your battery is goosed - and it's nothing to do with Odyssey, BMW or anything other than the way batteries are made and what happens with you fully discharge a starter type battery.

Sorry to hear of your ongoing troubles D...but also thankful that someone shares my pain

I haven't refitted the battery yet as I've been away but hopefully in the next weekend or so (weather dependant) I will give it a go.

I'm still convinced that something is causing the drain that is running them flat. Either that or you and I received batteries from the same stock. I have informed Motoworks of my problems and they have made a comment in my account for a return if needed.

By all means let Nippy's know that someone else on the forum is having similar problems. Hopefully between the two of us we can find a solution. By then it'll be spring and warmer temperatures and the issues will have 'cured' themselves.

 

[Demongroover]

Just had reply from Nippy, they are arranging collection of the battery.

Here is the report from the suppliers - Knight Batteries:

" The PC535GS battery from Derby arrived yesterday.

It was showing 12.8V on open circuit, after a short charging period I started the test which was a 15Amp load, the battery held it for 18 minutes before the voltage collapsed and the test stopped. This equated to 42% capacity

I was then able to put the battery on a full re-charge programme for 6 hours.

The battery was re-tested using the same settings and the battery managed a slightly better result of 48% capacity.

The minimum pass rate is 60%

There is no indication of any manufacturing fault, the likely cause of this failure is sulphation due to the battery being left in a discharged condition for a period of some weeks, it has in effect lost over half of it's capacity for useful work.

This battery is only fit for scrap, it is not a warranty issue."

However we will get a brand new tested battery sent out to you today and hope that this resolves things.
Kind Regards
Norman
