stolen 1990 klr (washington, dc)

[Michael Silverstein]

I'd like to be able to spend 8 hour days day working in the woods with my laptop and a battery/power source like this [http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_7962 _7962]. My laptop power supply says it puts out 4.5 amps (which I assume would be the upper limit drain, with a little bit thrown in for transformer loss) and the power source supplies 17 amps/hour, but I don't know how many hours it will handle a 4.5 amp drain and whether it will rapidly wear out from daily use/nightly recharge cycles. My goal is to commute on my KLR into the woods most days this Summer to do my work, but I'm not sure how to calculate how long the battery will supply the required juice.

Does the laptop not have its own battery that should last x hours ? Also would the laptop battery not just recharge off the jumppack while in use, then allow the jumppack to sit idle. Folks at work use these things alot for various thing on RV's when there is no battery installed, use them to run the slide outs out and in, run lights while inside if needed, and they seem to last a pretty long time inbetween charges. Could always use the supplied 12v charging cord and run your KLR to recharge the jumppack. Better yet buy the jumppack for home use and try it in the field. Watch Menards and the Home Depot type stores for sales, I got my unit around X-mas time at Menards for $24.99, I use mine at camp and camping to have 12v power for whatever I need it for, not to mention jump starting vehicles, always pack it when going to camp/camping.. never know when you might need it. Must be nice to have a job where you can sit in the woods for 8 hours doing your work. Where you work.. I need a job like that. There is a formula to figure out how long that pack will last, but will let a person that can quote it say it. Dooden A15 Green Ape --- In DSN_KLR650@yahoogroups.com, "Michael Silverstein" wrote:

""""""""""""""""""""""""""""""""""""""""" ????????????????????????????? ######################### Mike, Basically the way to figure out how long a battery will last on a full charge is to take the ampere rating (in this case 17ah) and divide it by the load (in this case 4.5amp). That would give you 17/4.5 = 3.7777777 hours till the battery is fully discharged. The battery in the pack you reference is AGM which means Absorbed Glass Matt. Just a newer technology than that found in the old lead acid batteries. These normally don't like to be fully discharged. My recommendation is to not rely on this to do what you have planned. I do like the idea mentioned by Dooden about just using the laptop battery. Maybe buy a second battery so you could use one and then the next. But I know some laptop batteries are pretty expensive, like in the hundreds of dollars. Hope this is helpful.

Mike, One other thing to bear in mind is that the laptop power supply will only go near that 4.5 amps as it is charging the internal battery. If the internal battery is charged already it will use considerably less or you could leave the internal battery at home and just run that way. We used to live off grid on solar power and I connected the older thinkpads direct to battery and ran at 12v DC, these days machines seem to want a higher voltage, so a small inverter type appliance is needed. have a look at the voltage specified on the internal battery, you may get lucky. -- Gavin Broadford Victoria Australia KLR650A18 DL650K6 Home of the DSN-KLR650 searchable archive at:- http://dsnklr650.gavinmac.com [Non-text portions of this message have been removed]

Thanks all. The piece of information I was missing was that amperes/hour is a measure of total energy available (N amps sustained over a period of one hour), which in retrospect is embarrasingly obvious. That's one more "duh" for me. My laptop battery right now is only good for about 15 minutes and even a new one will only last a couple of hours at best and they're not cheap. Removing the battery to reduce the load is a great idea. Thanks, Mike A18

I do agree, *but*: With 4 wheeled camping you usually just use a second battery that can be drawn from while isolated from the main. In this case you could strap a fully charged motorcycle battery on the bike and just use that without fear of hurting your main. This is really not all that different then the idea of getting a second laptop battery, but if you just happen to have an extra working moto batt (like I do) then this little "trick" should work fine. -- Doug Herr doug@...

...except that a "moto" starter battery is intended to provide brief periods of power and remain constantly charged. It is not a deep drain style battery that is expected to be completely (or partially) discharged and recharged on a repeated basis. Starter batteries will soon fail after several deep discharge cycles. Feel free to use up your spare battery since you have it, but when it comes time to replace it look for a marine/deep discharge style battery. -- Blake Sobiloff http://sobiloff.typepad.com/> San Jose, CA (USA)

List, I said NKLR, but it is for a KLR specific battery, shrug. I cut and pasted their words here. My Q'S are labeled "Q". smile. Guaranteed longer service life: The ODYSSEY battery, with an eight year design life and a three-to- eight year service life, saves you time and money because you do not have to replace your battery as often. It is also the ONLY battery that is capable of delivering a large number of deep cycles-up to 400 when fully discharged or up to 500 when discharged to 80%. Plus, the battery is specially designed for high vibration applications. Q. What is the difference between design and service life? Am I to think that it is 8 years from manufacture date? but only 3 from time placed in service? Q. What does it mean to us as an end user to have 400 deep cycles? Does it suggest you can run it down to 'zero' 400 times? Q.. Likewise, 500 times to 80%? How is this information useful in a motorcyle battery? In a trolling motor, yes, but in a KLR use? Q. How far down does a normal start take a battery, percent wise? Longer storage life: Unlike conventional batteries that need to be recharged every six to twelve weeks, the ODYSSEY battery will maintain up to 50% state of charge after 2 years if stored at room temperature (70F).At temperatures lower than 70F, storage times will be even longer. Deep cycle reserve power: With true 100% deep cycle capability, with 70% reserve power consumed, the remaining 30% state of charge still provides sufficient starting amps for solid confident starts. Only ODYSSEY can provide this unique level of performance. Superior cranking and fast recharge capability: The cranking power of ODYSSEY batteries is double to triple that of equally sized conventional batteries, even when the temperature is as low as -400F. Also, with standard motorcycle charging systems or simple constant voltage portable chargers, there is no limitation on the inrush current, so the user is assured of fast charge recovery. NOTE: No affiliation with Odessey, although I did see the movie 2001:S-O once a long time ago, HAL, HAL, can you hear me? or was it "Dave, what are you doing Dave?" and finally, Q. Anyone here use this, purported to be 'Just like the Marines' etc. revmaaatin.

Probably doing this in vain, but it doesn't hurt to spread the word. Stolen from NE side of Capitol Hill, Washington, DC on the night of March 19/morning of March 20. It's a 1990 model with the white plastics with the green and blue accents--the best-looking KLR *ever* in MNSHO I got compliments on it all the time. Picture here -- http://home.earthlink.net/~viffermaniac/90klr2.jpg DC tag # MT2820 VIN = JKAKLEA12LA016262 Pretty much stock except for the Givi top case, a Happy Trails bash plate, stainless front brake line and Acerbis hand-guards. Oh, and it had a Northern Virginia Community College parking sticker on the right-hand fork. Yes, it was fully insured, but given its age, I don't except a lot in terms of monetary compensation for my loss.
