NEWS BRIEFS The Good, Better and Best of Riders and their Relationship with Battery Chemistry Despite apparent production timeliness issues - even before the COVID-19 pandemic - Indian manufacturer Royal Enfield looks set to hammer another stake into the low price-point, low displacement market (if not exactly into the heart of Harley's Pan America ambitions) with the launch of a new $4,999 411 cc SOHC air-cooled single, switchable ABS equipped 'Himalayan' ADV model. The interim Business Head and President of Royal Enfield Americas says it is all about "the affordability, versatility and capability." Sources: AMD, IDN, FT, Reuters, PSB, MPN, B&B, BDN, MCN, AP, Bloomberg, MSNW, Electrek, electricmotorcycles.news, RideApart.com, Motor1.com On July 14, Missouri became the most recent U.S. State to repeal its compulsory helmet law, one that has been in force for 52 years. However, certain criteria need to be met in order to be able to ride without a lid. Riders have to be at least 26 years of age, with a full riding license and proof of health insurance. However, law enforcement officers are not permitted to pull a non-helmet wearing rider over to check if they meet those criteria. APB Corp, Tokyo (Hideaki Horie - the man behind development of the Nissan Leaf), has invented a new kind of battery that is said to be 90% cheaper to produce than standard lithium-ion batteries - and potentially much safer - by replacing the basic components of a standard Li-ion battery in order to speed up and simplify the manufacturing process. "Manufacturing the new batteries is significantly simplified by replacing the metal-lined electrodes and liquid electrolytes typically found within Li-ion units with a resin construction." KTM CARB filings appear to suggest that the 200 cc Duke will be headed for U.S. KTM dealerships soon. Okay, so it's not a 45 degree or even a 60 degree V-twin, indeed it isn't even a custom bike of any kind - just thought we'd mention it here, because KTM's North American dealers will be able to sell each one they get five times over! For the record - it is a four-stroke, single-cylinder rated at 25 hp and 14.38 lb-ft of torque, 308 pounds dry. As an entry level poster child, it is bound to prove to be a winner. A question often asked is why OptiMate has different battery chargers for lead-acid and lithium starter batteries if the two battery types work fine in the same vehicle, i.e. in a 12V vehicle charging system. Both 12V lead-acid and 12.8V lithium starter batteries work well within the 13V to 14.5V voltage zone required for a vehicle's ignition system to perform. That's why the stock lead-acid battery in a modern powersport vehicle can be replaced with a suitable LFP/LiFePO4 battery. In other words, for all intents and purposes, and without going into primary differences such as weight or cranking amps, for most riders a battery performs the same function - starting the engine, never mind the chemistry. If riders kept their batteries maintained every time they park their vehicle, not much else is needed other than an OptiMate 1 DUO, but we know that does not always happen! As soon as that battery is deadflat, you need a different type of charger to bring it back to life. Following deep discharge, lead-acid and lithium batteries require completely different reconditioning methods to successfully recover them from a vulnerable 'dead-flat' state - and "successfully" also means safely where LFP/LiFePO4 batteries are concerned. The four cells in a dead-flat battery will be in a critical state of health and need to be treated gently. High current or voltage will cause damage or even kill the battery. OptiMate lithium battery chargers automatically deliver controlled low current and low voltage to bring all cells safely back up to the normal voltage zone before ramping up charging. A sulphated AGM 12V lead-acid battery on the other hand will not accept charge at normal voltage (up to 14.5V). It needs a higher reconditioning voltage to overcome its reluctance to accept charge, and that's within the charge algorithm of both the OptiMate 3 and OptiMate 4 battery chargers - and it's a pretty smart algorithm too. If vehicle circuitry is sensed, it will not engage that high voltage SAVE mode. It's therefore best to recover that battery 'off vehicle'. The basic things to remember are that higher voltage kills lithium batteries, but a sulphated lead-acid battery needs higher than normal voltage to overcome its reluctance to accept charge - their responses are the opposite of each other. Secondly, at low voltage a lithium battery can only tolerate low current, but a discharged lead-acid battery can accept high current charge - again, the opposite of each other. So how come a charger such as the OptiMate 1 DUO works on both battery chemistries? Well, the DUO is a safe compromise. It does not deliver high voltage recovery, simple - and at low voltage it delivers only very low current. That said, it does still have plenty of 'smarts' - for example, its 24-7 maintenance program adjusts to the connected battery. For dealers it is important to sell the right OptiMate battery charger to their customers. Use the table seen here to navigate your way through the different customer habits that you have to allow for. The GOOD option is for the conscientious riders who never forget, i.e. always maintain the battery of their parked vehicle, with the BETTER or BEST options for those riders who may forget and need, on occasion, to save their battery or who simply prefer a battery charger with more features. www.tecmate.com www.optimate1.com 14 AMERICAN MOTORCYCLE DEALER - OCTOBER 2020 www.AMDchampionship.com
