Mercury | Smart Lead Acid Battery Charger 2/6/12V 600mA | Compact Maintainer for Car, Motorcycle, Lawn Mower, Ride-On Toys, AGM, Gel, SLA, VRLA | Polarity Protection – Crocodile Clips, UK Plug

With a maximum output of around 600mA, this charger is perfect for extended use. Many years ago, I laid a car up for 5 years, & to keep the battery & engine in good condition I would start the car once per week. I would leave the lights on (with the engine off) for about 20-30 minutes to help discharge the battery, then attach a 500mA trickle-charger to gently build the charge up again. When I started to use this car, the battery lasted a further 9 years without any problem.I bought this very similar charger to repeat the process during this Lockdown period & I am repeating the method described above. Of course, these days we have to consider that modern cars have sophisticated electronics that sometimes are still working when the car isn't being used, so therefore I think this makes it more important to keep the battery in top condition.This charger works very well: it doesn't get hot, and it delivers a nice, gentle charge. I have mine on a timer, which I have set to give around 8 hours charge per day. The only minor grumble is that the leads could be just a little bit longer, maybe by another metre or so, but otherwise this is an excellent unit and very good value for money.

The media could not be loaded. Having lost the charger for my grandsons 12v electric car, I did a lot of searching for a replacement charger but was surprised at how expensive they were.So I decided to order this charger, now you can use it straight out of the box by switching the switch on the front o 12v and then removing the seat cover on your kids ride on, which is where the battery is normally stored and clipping the connectors from the charger to the positive and negative terminals of the battery.The charger has a useful indicator which is green when charging and turns off when the battery is charged.I replaced the clip on connectors on the charger with a 5.5mm x 2.1mm male connector (which are very cheap) so I could plug directly into the charging socket of the ride-on car. Obviously only do this is you are happy changing the connector but it makes life a lot easier.The 600ma charge rate, takes a few hours to charge the car but does a good job.Overall I can thoroughly recommend this charger and was so impressed I bought a second for a kids 12v ride on trike.

Good value for the price, trickle charges my classic car nicely, and cuts out when the battery is fully charged. Be aware it is a 0.6amp charging rate, so takes a while if the battery is low.Cables are a good length and the clips fit securely on the posts.I would have liked a read out of charge level, but for the price you can't have everything!

Very pleased thank you

First class

At first, I was very disappointed with this charger. The design has resulted in the text on the charger to be upside down when plugged in :-( not a good sign.But, its performance is good. The green LED indicates when charging and goes out when charged. I checked the charge voltage and current with a digital meter, all the parameters were correct for sealed lead acid batteries.The voltage selector switch is a bit flimsy though.Over all, for the price it’s a good charger.

Didn’t charge it’s good for 6v battery not for 12v battery.

Does what it should, quickly and effectively.
