Prestolite Electric’s Leece-Neville IdlePro and IdlePro Extreme high-efficiency, high-output alternators extend battery life and improve electrical system and engine performance, according to the company.

The alternators deliver better output at low engine speeds to meet the electrical demands of modern commercial vehicles. The alternators produce more amperage at engine idle speed allowing for a performance improvement at low speeds. The IdlePro can put out 63% of its rated maximum output at engine idle speed while the IdlePro Extreme can produce a minimum of 90% of output at engine idle speed.

 Each IdlePro and IdlePro Extreme alternator includes Prestolite’s Isolated Ground Technology, which protects engines from potentially severe electrolytic damage caused by stray voltage.
