The **Schumacher 6/2 Amp Dual-Rate Manual Battery Charger **is designed to charge 6-volt and 12-volt batteries. I've only tested this on a lawn mower battery, which is a 12-volt, so I cannot really speak about the 6-volt charging. It is pretty simple to use: 1. Unhook the battery and ensure that the charger is not plugged in. 2. Attach the black clip to the negative terminal of the battery. 3. Attach the red clip to the positive terminal of the battery. 4. Select the volt/amp. 5. Plug in the battery charger. 6. Check the gauge to see when the battery is charged. 7. When it is, unplug the charger. 8. Disconnect the clips. 9. Hook up the battery and you're good to go. **What I like about this manual battery charger:** - We have a kids' car that has a lawn mower battery (ok - it's probably not as safe as the original one but this is how it was when we got it). The kids love to ride that thing all over the yard and we have fun watching them! After a while the battery runs down, and this charger has worked well to re-charge the battery numerous times. - It's easy to use. - It was reasonably priced - I believe we got this one at Walmart. - It's a fairly small size, although the charging unit would be even more portable if it were smaller. **What I don't like about this manual battery charger:** - My husband tends to plug it in before hooking it up. It makes beautiful sparks and arcs if you allow the clips to touch when it's plugged up. - It takes a while to charge. I don't think there is ever instant gratification when you're trying to re-charge a battery unless you have two and switch them out. - Some batteries may actually be drained if you hook it up for too long - I'm not too sure of that, but it seems like one battery we had didn't really hold a charge after we forgot and left it hooked up overnight. I would recommend setting a timer for something like two hours and checking the charge. It would be helpful if the unit would automatically shut off and perhaps give a signal once the battery became fully charged. **My Viewpoint:** This **Schumacher 6/2 Amp Dual-Rate Manual Battery Charger **has been a good investment for us as we have recharged a lawn mower battery numerous times and the girls have really enjoyed driving their battery-powered car around. It's simple to use, but it would be important to keep children and possibly husbands away from this thing when it's plugged in.
