Title: Battery recommendation
Post by: StuCorpe on August 23, 2015, 08:47:19 AM
So the battery is dying in my 03 EV. My question, is it worth the extra dollars for the Odyssey PC680 or should I save about $40 and go with a more generic AGM battery? They all seem to have similar ratings for AH and CCA. Sizes are all close.  What would you do? :violent1:

I made the plunge and bought Odyssey for two Guzzis 3 years ago. they're working great. The extra space gave me room for a tool bag. I bought them locally, batteries plus is a mile from my house. Although I've had no warranty issues, it's good to know they are nearby.

At the other end of the spectrum, I bought an 18 a-h generic AGM for my Mille a year and a half ago, and it continues to be an excellent performer.  It was $33.50 delivered, from eBay.

Yep, I used to get 2 or 3 years out of the old lawnmower battery too. <shrug>

I got the Odyssey 545 and holder from Harpers for the T5.  It is just about half the width of my old lawn tractor battery.  So, now I have a small parts box that I stuck in the extra space.

How long to you plan on keeping the bike? My last two Odysseys lasted 10 and 12 years, and I just changed them just because.. :azn:  maybe a case of overkill.

A generic AGM in my other motorcycle went five years or so until I killed it by accidentally discharging it to zero a few times.

Another vote for the Odyssey.  Had one for ten years in my BMW and when I sold it last week the battery still held a charge and required no more than 30 seconds on the charger before going into maintenance mode.  Can't ask more than that.

I have a Odyssey on the V50 which was given me after it had been discharged twice on a BMW with a faulty Reg/Rec, it behaves faultlessly on the V50.

I have a Generic AGM on My VFR800 (interceptor) which just hasn't got the OOMPH it should.

Well after much contemplation I decided to go with a generic AGM battery with slightly higher ratings than the original Spark 600 AGM. Primary reason for this was cost (I am typical Guzzi fan-read cheap).  Battery cost $35 (including shipping) on EBay. I guess I'll find out if it lasts or not. Original went 12 years so if I can even get half that life span I will be happy.

I may have asked this before, but ....

What kind of batteries do you use in your airplanes?    Looks like you'd have to be pretty careful about those even if the ignition is a magneto, you've got gyros and such that need good voltage .... ?

I don't know but I would suspect that anything voltage critical on an airplane will have it's own internal regulator.. 
If I remember right from way back in the day designing helicopter electronics we would expect the supply voltage to be anything from 38Vdc to 55Vdc..

I don't have an airplane so no idea. But I would tend to be less of a cheapskate if I did. :grin:

More critical for aviation would be temperature tolerance and attitude tolerance (like sideways, upside down) and vibration tolerance, and atmos pressure tolerance..
