Moin Moin, it is traditionally the time in the year in which one deals with the topic of starter battery. Mostly because the old one has given up the spirit. I got a Li-Ion battery from Shido last year and meanwhile also covered a few kilometers with the good piece. Conclusion: conspicuously inconspicuous. But what you notice directly: the XSR 900 starts better than with the old one. Where she has previously allowed herself a starter turn more, the good one starts right now. Vortei le: -Higher starter current -kaum Self-discharge – weighs only 30% of the old battery -charging status indicator Disadvantages: -less battery capacity -under -10°C no longer to be used Who wants to read it more about because of how/why/why, here is the detailed report.
