It replaces the old acid-fill 6N4-2A and its variants with an AGM that ships factory activated and charged, so it goes in the bike the day it arrives.\u003c\/p\u003e\n\u003cp\u003eThe battery this one replaces was a vented, acid-filled box that had to be topped off and that would spit acid onto a chain guard or a frame rail if it got tipped or overcharged. This one is sealed. The acid is locked into glass mat separators, there is no filler cap, and there is nothing to maintain beyond keeping a charge on it. On a forty-year-old bike with original paint under the battery box, that is worth more than the spec sheet makes it look.\u003c\/p\u003e\n\u003cp\u003eSix volts is what small-displacement bikes and trail machines from the 1960s and 70s ran, and the 6N4-2A is one of the sizes that turns up most often on them, along with 6 volt mopeds and some small engine equipment. At 2.80 by 2.80 by 3.80 inches it sits in the same rubber-strapped box the original came out of. People keeping old iron on the road around Painesville, Perry, and the Madison backroads come through the counter for this size every spring.\u003c\/p\u003e\n\u003ch2\u003eReplaces Yuasa 6N4-2A and These Part Numbers\u003c\/h2\u003e\n\u003cp\u003eDrop-in replacement for the following part numbers.

If your harness ends in ring terminals you will need a cable adaptor to land the connection cleanly. Motobatt makes a set of them, MP6NC3 through MP6NCD, and we can tell you which one matches your leads. Do not twist bare wire onto a lead and tape it over. A 6 volt system has no headroom for a bad connection.\u003c\/p\u003e\n\u003ch2\u003eKey Features of This 6 Volt Motorcycle Battery\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e6V, 4Ah at the 10-hour rate (4.2Ah at C20) in the standard 6N4-2A footprint\u003c\/li\u003e\n\u003cli\u003eSealed AGM: no acid to fill, no filler caps, no vent tube to route\u003c\/li\u003e\n\u003cli\u003eShips factory activated and charged, ready to install\u003c\/li\u003e\n\u003cli\u003e1.61 lbs and 2.80 x 2.80 x 3.80 in, so it fits the original battery box and strap\u003c\/li\u003e\n\u003cli\u003eGlass mat construction stands up to vibration better than a conventional flooded battery\u003c\/li\u003e\n\u003cli\u003eWire lead terminals, with Motobatt MP6NC-series cable adaptors available to match your harness\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003eMBT6N4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVoltage\u003c\/th\u003e\n\u003ctd\u003e6V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCapacity\u003c\/th\u003e\n\u003ctd\u003e4Ah (10hr rate), 4.2Ah (C20)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eChemistry\u003c\/th\u003e\n\u003ctd\u003eSealed AGM, maintenance free\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions (L x W x H)\u003c\/th\u003e\n\u003ctd\u003e2.80 x 2.80 x 3.80 in (71 x 71 x 96 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e1.61 lbs (0.73 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTerminals\u003c\/th\u003e\n\u003ctd\u003e2, wire leads\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCable Adaptors\u003c\/th\u003e\n\u003ctd\u003eMP6NC3, MP6NC4, MP6NC7, MP6NC8, MP6NC9, MP6NC10, MP6NC11, MP6NCD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eCharge it with a charger that has a 6 volt setting.
