 Seems like a good long-term maintenance chargerOct 29, 2008
By Graham
I wanted a charger to keep my car battery charged (but not overcharged!) while I am absent on multi-week trips. So far the Duracell 2 Amp charger seems to be working well.
It is a three-stage charger. The specification says that depending on the current state of the battery, it will do a fast charge to around 80%, then a slower charge to almost full, then finally move to a lower voltage "floating" charge to keep the battery near 100% without overcharging.
I used a multimeter to watch the charging process. My battery was mostly full to start with, so the charger started charging at 14.1 volts (the slow charge mode) and then after a few hours moved to 12.7 volts (for the floating charge). These both seem appropriate voltages. In particular, the floating voltage of 12.7 volts should be safe for long-term battery maintenance.
After about two days on floating charge, my charger's red charging light finally went off. Over the next couple of weeks, when I checked the charger, the red charging light was mostly off but I occasionally noticed it on. It looks like the charger is moving between off and floating charge as needed for sustained maintenance.
I'll have to see how the charger holds up under long-term use, but so far everything looks good.
Update November 2010: I've been using this for two years now and I continue to be very happy with it. It's pleasant to come back from a four week absence to a fully charged car battery, with zero hassles!

I use this with my classic motorcycles and it's taken a beating. Gotten soaked and dried out. Fallen to the concrete floor on numerous occasions, and it's still running like a swiss watch.
All the connectors are great too.

Great Product!! DOES WHAT IT STATES!!Jan 18, 2009

This product is great!! It also has a low price.
I bought this for the cold winters here in Iowa. I have older cars they are 96, 92, 01. I just connect them through the lighter option connection and switch them every day.
My cars always start now. No problems at all.
This charger/maintainer is perfect for older cars that tend to lose their charges during cold sub zero cold nights.
Would highly recommend!!!

 Meh - OK, not sure why so many 5 starsMar 26, 2010
By Gadgetitis

I have several chargers already, but decided to pick one up for $10 during a holiday special. The D2A is a rebranded unit made by Xantrex Technologies ([...]) Nowhere on the box or in the manual does it mention being a microprocessor controlled unit (only on Amazon description). Also on the back of the box it mentions being a 3 stage charger, but actually it is only 2 stages (bulk/float). The float voltage seems high, compared to my Yuasa charger - I hope that doesn't damage the battery. This charger will cycle on and off every 5 min or so in float mode (probably ok). When it goes into float mode, the red LED does not shut completely off, but has a faint glow. Also, when connecting the leads to the battery, there is definite sparking sometimes, which means it is pumping current out on initial connection (A high quality microprocessor controlled charger will do a "soft start" with no sparking.
I just picked up a SEM-1562A (Aug 2010) and so far it works better than the D2A (better build quality, three LED status lights with more status modes including blinking LEDs). It has a soft start feature and does not spark on connecting to battery.
