It charges reliably and the trickle function is useful for maintaining batteries over time.A bit expensive compared to some alternatives, but the quality is what you would expect from Bosch. ### ⭐⭐⭐⭐⭐ Saved me a fortune on a new battery 😊 *by on Reviewed in the United Kingdom 6 May 2024* My Merc doesn’t get used much since working from home has been a thing for over four years now, I found my stop start was non existent (didn’t use it but good to know it works!) and kept getting messages of a low battery. Mechanic said battery was in good condition and to try this charger, so I did!Initially I thought my battery was completely broke, this trickle charged for about 3 days solid, but eventually got to 100%. Took my car out for a drive and the stop start worked straight away.The quality is this product is second to none and it’s IP65 waterproof too, so was easy to hook up my car and shut the hood and leave it to it.Saved me a big bill on a new battery, loads of feature to keep you safe, I’m not particularly mechanically minded but had no fear in using this charger. ### ⭐⭐⭐⭐⭐ Good buy *by on Reviewed in the United Kingdom 12 March 2026* Excellent charger, simple to use compact and good build would recommend. ## Frequently Bought Together - Bosch C30 Battery Charger, 3.8 Amps with Trickle Function - For 6V/12V Lead-acid, EFB, GEL, AGM and SLI Batteries, Comes with a UK Style Plug - Bosch Connection Cable for Battery Chargers - Battery Cable with Ring Lugs and 10 A Fuse - Original Quality Spare Part - M6 Eyelets, 52 Cm Cable - 0189999270 - JOREST 168 Pcs Car Fuse Assorted Kit, 114 Mini Blade + 54 Standard+ 1Pullers – 11 Specifications Mixed Auto Fuse: 2Amp 3A 5A 7.5A 10A 15A 20A 25A 30A 35A 40A --- ## 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.pl/products/568961917-c30-battery-charger-3-8-amps-with-trickle-function-6v](https://www.desertcart.pl/products/568961917-c30-battery-charger-3-8-amps-with-trickle-function-6v) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-08-31*
