Battery

I'm sure it's been done to death....I've searched high and low....Haven't found a solid answer. Many long rides. Many straight down the interstate with heated gear. Not alot of short trips, but a few. Voltmeter installed. What do you long timer, high milers use and recommend. I need to buy, and I want to spend my money on the right product. Which battery?? Thanks much for any help.

I still use the flooded battery that came in my KLR 18 months and 18,000 miles ago. I usually buy Yuasa batteries for bikes, but if this "EverStart" brand battery won't die, I won't replace it.

I add distilled water regularly. The large syringes from used for fiberglass/epoxy are great for getting water into motorcycle batteries.

The KLR charges at such high voltages that I wouldn't put an AGM in there. I have a Deka AGM battery on another bike that charges at a lower voltage. The manufacturer recommends that the "float" charge is always lower than the voltage that my KLR runs when on longer trips. After starting the bike and running around town, the voltage will stay lower as the battery charges, but it will eventually charge at over 14.5.

Battery electrolyte will "boil off" at 14V or above. (Actually the water breaks into hydrogen and oxygen by electrolysis, but saying it that way is pedantic.) A flooded battery at least allows me to let it boil off and replace the water.

Other battery types are less forgiving of high voltages. Gelled, AGM, Lithium (of various types) all need lower voltages. And I look constantly. Some new lithium batteries come with circuitry to prevent overcharge and I would seriously consider one for the KLR.

My house runs on lead-acid batteries charged by solar that I installed myself 12 years ago and a wind turbine that I built myself a couple of years ago, including winding the coils and carving the blades. I'm serious about batteries.

After killing my led acid battery by not checking the fluid levels often enough I went with a Trugel sealed battery. It's been on the bike since May of 2011. No maintenance. Set it and forget it.

Here's some info

They are a bit more expensive than other batteries though. Mine set me back about $100

Thanks very much. There are so darn many choices in types and prices it's great to hear what's working and what to avoid!

What year bike? I swear by the Odysey 545 as it can be installed sideways etc. It fits easily but you will require to pull the neg battery cable out and reroute it. Simple job. The battery is bullitproof and the first one lasted me 5 years. It is a more expensive unit compared to the Wally World crap but you get what you pay for and seeing as we don't have a kickstart a good battery is crucial!

I've had this Deka in my bike for 4+ years still going strong. Direct OEM replacement, fast shipping too.

+1 on the Deka. I slapped one in my klr last spring, it even spins the old girl over quicker than the stocker ever did. Well sealed to, because the boneheads shipped it upside down and it never leaked

Re: Battery

Oh, I should say I didn't buy my battery from the same place Spec did, got mine from an outfit from Ontario, lol, my shipping was far from free!

The folks that use AGM in their KLR haven't said they use them for long spins. They may, but they haven't said.

The technical manual for Deka batteries is here: http://www.dekabatteries.com/assets/base/0139.pdf

The voltage chart at the bottom of page 11 is the one for AGM batteries.

The way I interpret that is that you'll be fine for around town, fine for stop-and-go, and fine at lower RPM on tracks.
