Heya!

After almost giving up I think I've finally found a Gel battery for the CS that shouldn't require any modifications (eg. Taking a hacksaw to the Battery container and underseat) :

http://cgi.ebay.co.uk/ws/eBayISAPI....m=190168434067&ssPageName=STRK:MEWA:IT&ih=009

As the advertisement is in German, I used Babel Fish to translate:
http://babelfish.altavista.com/

The dimensions are the same as my currently fitted battery except the height is 2mm higher. They quoted me UK postage of 21.80 EUR which brings the total price to about 70 quid. Pricey, but if it lasts twice as long as a regular battery, it doesn't seem too bad.

Can anybody see any probs before I go ahead and buy?

Problems?

Far from it, gel batts should be standard fit for 650's. Strikes me that for the same cranking power they seem to be one-third smaller than originals, so I assume you'll be getting almost double the previous cranking power from one fractionally larger than original. Critically, it seems you've found the one which doesn't need any mods to fit your bike, compared to other forum users. Apres-vous, la deluge.

Got a Hawker gel jobbie on my Funduro, one-third smaller than original but 150% power, space saving means a full set of spare bulbs in a little box on top of the battery. Bike lives outside, I hits the seat with a lump of wood to crack the ice in winter, still starts first time. Expensive but value for money, wouldn't hesitate to recommend one and if ever I bought a bike new, I'd want a deal on having one fitted by the dealer. He can put the lead one on the shelf.

No need for the Accumate trickle charger anymore, sold it to recoup some of the cost (these chargers just haven't got the goolies to shunt energy into 21st-century gel batts)

Confident now? MK

Do a search on the forum for Westec. I am a big convert to the Gel battery. The westec is slightly larger than OEM but fits without mods to the GS but from what I have heard the same applies to the Scarver.

if I remember correctly I found one on ebay for around £50 delivered

Well I went for the plunge and the battery has just arrived today!

The only problem is I've noticed something on the box. The ebay listing specifically says 12 V 12 AH, but on the box it says - min 14.1V / max 14.4V - Does anyone know if this battery would fry my bike? Would hate to send this back, would definitely be a pain in the arse returning it to Germany :think:

Help very appreciated!

Your regulator should be putting out about 14 volts to charge the battery. You should be fine if it was rate for motorcycles in the first place. U will be surprised by the cranking power though :-D

got my battery installed and it's fantastic! Great kranking power, I think the little engine had no idea what hit it first time I started it up :). Very happy :).

The problem I'm having now is that there's too much power :roll: . I used to be able to leave my fog lights on for some great extra spread for cornering at night and it never seemed to bother other drivers. Now my lights are brighter and I'm getting angry flashes from passers by! I'm just leaving the fog lights off for the time being but I really miss the extra wide spread :think: . I guess I have three choices:

- I could move my switch somewhere more accessible (currently under my clocks), so I can easily switch it on and off - two switches may be annoying to manage though.

- Rewire my switch so it feeds off the high beam cable instead of the parking light cable. Which is fine except for that my low beam is useless alone.

- The lamps take 12V H3 55W bulbs, would it be possible to get lower wattage bulbs? The fog lights really do tend to suck a lot of power and even with the Gel battery I can feel that cranking power is less after using them. Would be happy to lose a little bit of brightness if it used less power.

What do you guys think?

Cheers for the help!

Leave switches in situ.

Rewire to only activate frogs with main beam.

Replace main/dip bulb with Phillips Hi-Power.

This will give you a substantial boost to dip beam without causing a round of applause from oncomers, but when there's nothing in sight you can weld kerbstones from 50 metres.

Double-check your foggie alignments with bike loaded, horizontal is cool but if oncoming folk are flashing, you ain't dropping the fog beam quick enough with your present set-up. You may want the extra spread/watts during dip, but if you're being repeatedly flashed the total effect on your eyes is of a diminished capability.

I know what I mean, ain't sure if it reads what I meant. MK

Cheers guys!

I'll look at getting the foglights switched to high beam and lowering them. Hopefully lowering them will make a difference, they have a huge spread with no obvious hotspot though.

Thanks very muchly guys, as always a huge help :)

i think i must have missed something.

first up (and i'm just being ignorant here), what's a gel battery?

is it just the CS which has a bit of trouble getting one to fit?

and do they need specialist chargers?

my dakar is kept outside and so would benefit from a nice powerful bettery.

Rich,

We're benefiting from 21st century technology now. Lead acid is reliable, dependable and well understood due mainly to the length of time we've been using them, but they do need care and attention. Imagine the size of one on your mobile phone though.

Gel batteries are smaller, deliver more cranking power, but really need to be charged by the bikes on-board charging system, so we need a new thinking head on: keep the bike charging system in good condition, sell the battery charger and trickle charger. Gel batts won't fit your mobile, but knock-on effects across the battery industry from NASA/mobile evolution are there to be taken advantage of.

Overall, I doubt you save money - you can pay up to three times more for gel, so shop around, but you won't need £40 worth of trickle charger and, unless you're good with electronics, you'll need to do a fair few calculations to get the right charging rate for a bench charger. An on-spec bench charger ain't going to be on the shelf at Halfords.

Plus points - fit in any position or orientation (not sure about upside down), pro-rata 50 - 75% of same spec lead acid size, about 130 - 160% power output for the same size, zero maintenance (but some goo on the terminals doesn't hurt), engine starts out of fear.

Minus - they're dear.

If you are not dependent on your bike for, e.g. getting to work, then perhaps a lead-acid is more suitable, especially if it is garaged all the time. MK

After much debating over going for a gel battery I went ahead and purchased one.

The difference when cranking the bike is amazing! Well worth the money as my bike is stored outside and cold starts in the past have been an issue.
