Lead-acid batteries for SLI (engine starting, lighting, ignition) uses have an average life of 3-4 years. The ITE Yeager Battery Research Institute (Japan) has developed a new chemical (organic polymer) which prevents sulfation of new batteries and recovers deteriorated batteries from sulfation. By using this new ITE Kozawa Activator (an organic polymer is the main chemical), the service life can be extended into 5-10 years and also the lead plate can be reduced by 25-50 %. This means the current SLI batteries can be made smaller and lighter.
