BoschC80-Li Battery Charger - 15 Amps with Trickle Function - For 6V/12V Lead-acid, AGM, EFB, GEL, SLI and 12V Lithium (LiFePO4) 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.

Mode button not working, won’t even switch to charge mode. Very disappointed

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.

Amazing product. Bought now due to the cold winter eliments to help condition the car battery. Now I had bought an alternative brand a good while back but was never to sure about it.Saw this product pop up and though I'll give it a go. Pleasantly surprised. Starters the packaging is good as everything is in its place with the carry case provided.The charging process, the cables are long enough to get a good reach. The modes are easy to select through and the instruction booklet finally has clear instructions especially for agm batteries as to what modes are the best to use.Overall, very happy with the purchase and highly recommended.

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.
