Better battery?

34 degrees this morning.
Went to start the beemer to move it and it barely cranked despite being on a trickle charger for the last 48 hours. Battery is a gel unit and I've noticed that they really lack cranking ability when below 40 degrees. On vacation on a 21 degree monrning we started it by pushing down hill.
I have checked the entire charging system and verified proper function so it's the gel teechnology that seems to be the issue.

On the other hand, the Suzuki C90T parked next to the lt fired up like it was 90 degrees outside. It has a traditional battery on board.

Are there any bettter batteries that will fit in the LT available space?
Help is appreciated !!

Re: Better battery?

Gel batteries suk big time. Last word on battery is Odyssey p680. It is a AGM and will last many moons. Superb cranking and charge holding. BTW- try "search" function and word "Battery". It works for many other questions too.

Re: Better battery?

I buy cheap battery's at Advance Auto. My LT's crank over just fine in single digit temps. & I don't use a trickle charger unless one of my LT's is going to sit for several weeks.

Re: Better battery?

AGM's are as good as it gets right now for a general-purpose, all-around battery. While all batteries deliver less power at low temperatures, gels are a lithe worse than most. They are also easily damaged by overcharging, where AGM's will tolerate higher charging voltages.

Because of their construction, AGM batteries are more resistant to separator failures (which are the main cause of early battery failure) as well as filament growth (which is a problem as the battery ages).

Lithium batteries may be a good choice for some applications. Their light weight makes them tempting, but they require a peculiar charging sequence (constant current for bulk charge, followed by constant voltage to top it off) and are really poor below 40 degrees. The charging issues are normally handled within the battery (I think, the open literature on this is not clear), while the battery can be warmed up on cold starts by running your headlights for a few minutes, but it is still something you don't have to deal with with an AGM.

If keeping weight low is a big concern, go lithium, otherwise, AGM seems the best choice.

Re: Better battery?

Ole Toad has been fitted with just about every battery that will meet specs for an LT - just received a WestCo AGM battery, on sale, from Beemerboneyard. Arrived 2 days before scheduled tracking menu - put it on a Battery Tender Plus and will swap when full up charging. Am replacing a UPS (sp ?) Panasonic that's about 4 years old. We do like the Odyssey PC680, butt they've run away with their pricing, so we'll see how the WestCo does - 12V 20Ah.

Dick,

My Westco ran strong for straight 5 years without a hick up. Good luck with yours.

Thanks, Les. I've come to like AGM batteries. Been pretty strict with Battery Tenders on 'em - I think they like that.

Re: Better battery?

Same as Saddleman. Get a cheap and cheerful battery from you local bike or lawnmower dealer and it'll do just as good. Mine cost 48 and is on year 4.

Re: Better battery?

Just curious if you have your battery on a trickle charger or a battery tender. That might make a difference if the battery is not up to a full charge on the LT. Even in Florida, if my LT did not have a full charge, there were hesitations on start up.

I've always used a battery tender, not a trickle charger and when I use it, had good results. Standard batteries lasted 3-4 years.

Re: Better battery?

As others have said, AGM is THE way to go. I have 20,000 miles and nearlty 3 years on my Panasonic AGM battery and it still starts like when it was new. I keep the bike on a Battery Tender Jr after every ride and until ridden again. The Panasonic replaced a 5 year old Westco that the previous owner had installed. I only replaced the Westco because I knew I would need to and found the Panasonic at a good price.

Re: Better battery?

Here is an interesting thread on another forum about going to a larger battery for the K1600. The information is very detailed.


http://www.k1600forum.com/forum/bmw-...ion-tests.html

I'm surprised that your gel battery, at 13.8 is having a problem, unless something is putting an unexpected load when you start it up. Is your headlight staying on when you crank it up?

Re: Better battery?

headlight goes out when starting. Radio and comms turn off during start.

I tried leaving the PIAA lights on for about 2 minutes this morning in hopes of heating the battery and that seemed to make a huge difference.

I think the gel is going out and an AGM is coing in, very soon.

Re: Better battery?

First choice PC680.

Second choice any VRLA (valve regulated lead acid = maintenance free)

Last choice any battery with a drain tube on it.

Re: Better battery?

August of 2004 is when I picked up my bike, it still has the original battery almost 9 years later, is there a better battery out there,? I doubt it.
