CTEK CT5 Powersport 12V Motorcycle Battery Charger & Maintainer (Lead Acid & Lithium)

Regular price $ 89.99

Motorcycles, ATVs, jet skis and snowmobiles often sit for weeks or a whole season at a time, and that's what kills powersport batteries. The CTEK CT5 Powersport is built specifically to charge and maintain those smaller batteries, with dedicated programs for both lead-acid and lithium (LiFePO4) batteries, so it covers your bike whether it runs a stock AGM battery or a lightweight lithium upgrade.

It's fully automatic and can stay connected to the battery indefinitely without overcharging or undercharging it. Built-in temperature sensing adjusts the charging voltage to the conditions in your garage, shed or trailer, and a reconditioning program helps restore stratified and deeply discharged lead-acid batteries.

Both alligator clamps and eyelet terminals are included, using CTEK's Comfort Connect quick-connect system. Leave the eyelet lead on your bike's battery and just plug the charger in when you park it.

Key Features

  • Three automatic programs: Normal for all 12V lead-acid batteries including AGM, Lithium for 12V LiFePO4 batteries, and Recond to restore stratified and deeply discharged lead-acid batteries.
  • Connect and forget: safe to leave connected for long-term storage; it maintains the battery without over or undercharging.
  • Built-in temperature sensing: charging voltage compensates automatically for ambient temperature.
  • Low start voltage: begins charging lead-acid batteries from 2.0V and lithium batteries from 5.0V.
  • AGM ready: handles demanding AGM batteries such as Optima.
  • Splash and dustproof: IP65 rated.
  • Safety built in: non-sparking, reverse polarity protected, short-circuit proof and designed to protect vehicle electronics.
  • Comfort Connect system: works with CTEK's eyelet, extension, cig plug and indicator leads (sold separately).
