Will this work-- or is it overkill?** A: I can recommend this battery charger. The reason is that performance and usability are very good. I think it is a good choice to use even if you buy a large car. **Q: Alternator test work on motorcycles too?** A: Yes ... make sure the battery is fully charged so you won't get a false result. Switch the MODE button to alternator >> start the engine and hold it at 2000 rpm >> if it is charging less than 13.3V it will light up (BAD) >> 13.3V-14.0V (FAIR) >> and above 14.0V (OK). **Q: What is the difference of this one from model 56-864? They seem identical** A: model #56-864 doesn't check your Alternator to see if it is charging u battery **Q: Is this unit also good for trickle charge?** A: The product description and other web references say it will work as a trickle charger. In fact the unit goes into a trickle charge mode after it cycles through the battery tests and reconditioning steps. I have used it as a trickle charger for days in a row on a car that gets little use. So far I am satisfied with the product. ## Frequently Bought Together - CTEK 4.3 Test & Charge, 12 Volt Fully Automatic Charger with Unique Battery and Alternator Testing, Ideal for Long Term Storage - CTEK (56-304) Comfort Connect Extension Cable, 8.2 Feet - CTEK Connect CIG Plug, Permanent Connection for Hard-to-Reach Batteries, Easy Connection to Your CTEK Battery Charger Using The Vehicle 12V Accessory Sockets, for Cars, Motorcycles & Other Vehicles --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/14650898-ctek-4-3-test-and-charge-12-volt-fully-automatic](https://www.desertcart.at/products/14650898-ctek-4-3-test-and-charge-12-volt-fully-automatic) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-21*
