R1150R Eating Batteries

Post by TNOutback »

Just bought a new-to-me 2002 R1150R last week from the local dealer. Only had 2100 miles on it and was a local trade and the dealer had complete service records on it. Reviewing the records I thought it odd that the bike was on its third battery since last June. It was a bit slow to turn over, so I got it home and hooked it up to a battery tender to charge. In short, the bike is only good for one start. If I stop the bike and try to restart it, it will only give me the clicking noise and won't turn over.

The service records indicate that last year they checked for phantom loads and checked the alternator output, and everything was OK. Obviously everything is not OK. It should not be going through batteries like this, correct? Any thoughts?

If the bike is two weeks old, I would return it to the dealer and insist that they look into and repair the problem, unless they advised you that tyhe bike had some issues.

Three batteries in 9 months definitely points to and electrical problem and that doesn't compute with the dealer's position regarding their testing of the electrical systems as the bike would have been in the same condition when you bought it as it is now.

Irregardless of the battery quality, if it has been failing as you indicate there appears to be a draw on the battery (amps) above and beyond what's normal. With the key in the off position, the only draw on the battery is the clock and that should be less than 100 ma, if more there is a dead short somewhere.

They had to know about the issue when they sold the bike, at the very least they should execrcise due dilligence and repair the problem, if they become difficult move into a partial payment for their services, but stand firm.

Keep us informed of the outcome.

Take my advice and replace the original 2001 battery with a PC-680 before it starts leaking and damages the battery box like my `03 battery did. I am amazed the OEM battery lasted you this long.

I'd be checking the starter pinion as it slides forward and engages the flywheel. Mine got all cruddy but I was able to free it up with a squirt of liquid oil like WD40 or similar. You need to take the plastic cover off the starter and pull a couple of long bolts out but it's not hard. Should be a warranty thing if you bought from a dealer.
