Awesome charger in small compact form
I remember when battery chargers used to be the size of car batteries, so I was a little skeptical when I seen the size of this charger. It's about the size of a check book, or more precisely, the size of the box your refill checks come in. This charger is totally automatic. All you need to do is attached the positive and negative wires to your battery (after plugging the charger to a wall socket or extension cord) and the unit will do the rest. The first thing it does is analyze your battery to make sure that it is "good". If the battery is good, it goes right into charging the battery and it will display in percentage what state your battery was in. For example, both my car and motorcycle batteries were dead. I picked up the charger in the morning and attached it to the car battery around 11:30am. The indicator stated the battery was good and was at 97%. I checked the battery throughout the day and evening and around 11pm, I noticed it was now in "maintenance" mode (i.e. trickle charging). I went ahead and disconnected the charger from the car and placed it on the motorcycle battery. The motorcycle battery was also good and at 37%. By 6:30am, the charging was complete and was in maintenance/trickle mode, so I disconnected the charger and unplugged it from the extension cord. The instruction book doesn't state what the percentages mean, but I gather that the car battery at 97% meant that it was "almost" completely dead. The car wouldn't crank at all, but on the motorcycle, with 37%, it tried to turn over but ultimately the battery just didn't have a strong enough charge. The charger comes with 3 types of connectors, with quick release connectors. I just used the standard gator clips as shown in the picture as those are easier to connect to the battery terminals. I tell you, this was a great purchase. I have 3 cars and 1 motorcycle, so at times one of these vehicle will sit for quite some time and usually the battery will be dead. The car I spoke of earlier only sat for less than 2 weeks before the battery died. This was a brand new battery i got from Sears back in November, so I know it's not a bad battery. I must have some sort of accessory that is slowly draining the power. I'm not sure what it could be though. I have these aftermarket illuminated gauges for my dash board that needs to be manually turned off and I've left them on accidentally for 2 days and never had a dead batter. I know I didn't leave them on the last time it sat for two weeks so I need to check for something else, but at least I have this battery charger now. Only bad thing about this charger is that the cord is really short. After getting a just start to move my car, I had to park really close to the garage door so that cord (attached to the extension cord) would fit beyond the garage door. I mean, it wouldn't make much sense if someone came along and could unplug my charger from the cord, but at least with the connector beyond my closed garage door, it would make it more difficult to unplug.
