Rated 5 out of 5 by from No frills but worked fine This charger has 3 leds. On, charging and charged. It took 4 hours to charge small Peugeot 108 battery. Worked a treat. If you want more information regarding the charge status and batter levels you need to get a better machine. If you want to put on charge and leave until ready, this is great.

Rated 5 out of 5 by from Great little charger I was looking on line for a charger as my old charger finally died after many years of being worked. As l was a bit unsure of witch one to buy l got on the phone and asked for advice as l mainly use battery chargers for charging up my batteries for my fence lines on my farm. I was put onto this one, but l was also told l could ask about more info at my local store to make sure it was the right one. I got down to the store and also giving the same advice so l brought it. I am happy to say as an o.a.p l find it light to carry and it works very well. It has charged all my field batteries up ready for use and l am very happy with my purchase.
