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

Good, solid charger that feels well made and is very easy to use. 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.

Excellent charger, simple to use compact and good build would recommend.

Excellent. Did the job perfectly. The hook was useful to hang up the charger under the bonnet. Worked well on my dad's mobility scooter. Saved the batteries.

Having a 95ah car battery this doesnt charge as quick as I would have liked. I should have used the 10% rule and looked for one around 9 - 10 Amps but other than that its good quality. I know I probably should have done my research before buying but I thought for the money it would have some sort of internal switching process for a faster charge to a certain percentage

Usual Bosch quality and easy to use. I brought it for my daughter so she can keep her car battery charge in winter. She manages to use it with zero input from me. Would recommend

High quality materials. Very compact unit. Easy set-up. Charging time for completely discharged battery (1.6l Diesel with stop start) 50 % 1/2 hour (maybe enough to start in emergency - I didn't try) 75% 2 hour 100% 4 hour I have no comparison, so up to you to decide if this is good.

Complete the work perfectly

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.
