Bosch C10 Battery Charger, 3.5 Amps with Trickle Function - For 12V Lead-acid, AGM, GEL, EFB and SLI Batteries, Comes with a UK Style Plug

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.

Easy to use and very quick charging.

👌

It is the best charger I've ever owned. It is a good size—not too big—and can do a lot of settings automatically, which I find handy. I definitely can recommend it.

Bought this, left it on for hours. Did nothing. More money doesnt mean better product! Confusing instructions, confusing interface. No clue whats even going on.

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 hour100% 4 hourI have no comparison, so up to you to decide if this is good.

Has proven invaluable to revive and charge hybrid battery low from lack of use in winter. Would prefer an LED level indicator rather than different coloured LED further confused by step throgh ability (and more LED) to cope for different battery types I've never heard of- could confuse as instructions somewhat brief.

Cheaper chargers available but this Bosch ones well made and does everything it needs to.
