[QUOTE="RossKean, post: 1452069, member: 19880"] Storing a battery on a concrete floor will not harm it in any way. The hard plastic case is non-conductive and will not discharge, absorb moisture or release acid. This may have applied to much older battery generations... It is, however, a good idea to keep the top of the battery clean (salts, dirt or acid residues) and protect the terminals from accidental contact with anything that might cause a short circuit. It is best to store the battery fully charged, especially if storage location gets very cold - freezing point for a fully charged battery is much lower than one that is discharged. Personally, I never use a battery tender and don't normally disconnect the battery from the bike although using a properly functioning tender or maintainer (not trickle charger) won't hurt anything. Unlike some battery chemistries, lead-acid and AGM batteries "like" to be kept fully charged. They also don't "like" to be deep-discharged or "cycled" although some types are designed to be more tolerant of cycling. A modern AGM battery [B]in good condition[/B] has a very low self-discharge rate (a few percent per month) and the FJR has a very low parasitic draw. To be safe, I will do a top-off charge maybe twice over a four month layoff using a one amp charger for a few hours. (Current OEM Yuasa battery in my 2011 is almost 12 years old and has around 100,000 miles on it...) [/QUOTE]
