ELIIY Power Announces Adoption of HY93 Lithium-Ion
Starter Battery in Honda’s Mass-Produced Motorcycles forthe first time
ELIIY Power Co., Ltd. (Head Office: Shinagawa-ku, Tokyo, Japan; President: Hiroichi Yoshida) today
announced that its HY93 lithium-ion motorcycle starter battery has been adopted for the「CBR1000RR Fireblade SP/SP2」sport bike to be released by Honda Motor Co., Ltd. (Head Office:Minato-ku, Tokyo, Japan; President: Takahiro Hachigo). This will be the first time Honda uses alithium ion battery as the starter battery for a mass-produced motorcycle.
Co-developed with Honda, HY93 is a lithium-ion motorcycle starter battery that is interchangeablewith a lead-acid battery. The HY93 is based on the core technologies that ELIIY Power has built up in
the field of stationary batteries to offer world-leading safety*1, long cycle life and wide operating
temperature range. It meets all the requirements of a starter battery in terms of safety, excellent
startability and long cycle life.
*1 First to acquire certification of the safety standards (Abuse Test Manual for Lithium-ion cells v. 2:2011) published by TUV
Rheinland Japan Ltd., a global third-party testing and certifying body.

◆Details of Features
1．Interchangeable with lead-acid battery, maintenance free and can be left unused for along period of time *2
In the past, lead-acid batteries have been used as motorcycle starter batteries. However, thedrawback to lead-acid batteries is that they go flat if unused for a long period of time, requiring
users to charge batteries regularly during winter or prolonged storage. Lead-acid batteries also
have a short life and need to be replaced every few years. Lithium-ion batteries, on the other hand,
have the advantage of being more compact and lightweight than lead-acid batteries, and having low
self-discharge and a long cycle life. However, the downside is that when used as starter batteries,
lithium-ion batteries are inferior to lead-acid batteries in terms of safety, engine starting
performance at low temperatures and the deterioration was also a problem when charging at lowtemperatures. ELIIY Power solved these issues with its own technologies and developed a starter
battery that could start an engine in the wide temperature range from cold ( -10℃) to hot (65℃).
Even in an environment at -10℃, HY93 demonstrates powerful engine starting performance.
*2 There is no guarantee that the HY93 is maintenance free under all conditions since it relies on the dark current flowing throughthe vehicle when the engine is stopped.

2．High level of safety recognized by Honda and TÜV Rheinland Japan Ltd., a global
third-party testing and certifying bodyA starter battery is a product that may come into direct contact with users’ hands and a high levelof safety is, therefore, required. The HY93 battery cleared Honda’s strict quality standards and alsoacquired safety certification*3 from TÜV Rheinland Japan Ltd., a global third-party testing andcertifying body. The HY93 battery has a BMU (Battery Management Unit) built in the battery pack toenhance safety not only in terms of the battery but also in terms of system control. It also has a PPS(Polyphenylene sulfide) resin external coating, offering excellent durability and environment
resistance.

ELIIY Power has realized high safety of large-lithium-ion batteries and played a leading role in theenergy storage market, developing long cycle life and wide operating temperature range. Thissafety and technology was recognized, and two years ago ELIIY Power began co-development ofstarter batteries with Honda. In 2015, ELIIY Power concluded a technical sponsor agreement withHonda Racing Corporation and conducted repeated testing under harsh conditions in actual
motocross events. This motorcycle starter battery will further develop in terms of size andperformance as the HY Series, and ELIIY Power plans to enter the aftermarket for those whowould like to replace their lead-acid battery with lithium-ion one in the near future.
