Works as advertised. I just wish the battery selection was more intuitive.

Smart charger from ATian. Overall I'm happy with it, but there are a few quirks to watch out for. Firstly, it can't be used as a battery tender - which means you can't connect it to a battery in winter, for example, while waiting for a charger to keep the battery going. Once the battery is fully charged, the device will turn off completely. It only turns back on if you manually press the power button. This is completely sufficient for the usual needs of the charger. Just something to note. Next comes the choice between AGM and Gel batteries. Talk about confusion. Most batteries will state what chemistry they use - where it's AGM, Gel, Flooded Lead Acid (FLA), etc - but if they don't, it's pretty much a shot in the dark. The description says it can charge flooded lead-acid, deep-cycle, AGM, and gel batteries, but there's no setting for those types. I've done some research and it looks like a flooded lead-acid battery - a type of battery that you either add acid to or you can top up with distilled water - tends to use charging options similar to gel cells, so I'm guessing that you decide for this type for these types. batteries. The description also says you can change the battery type **while** the charger is charging. It is not true. Once you press ON, the buttons have no noticeable effect. However, I noticed that pressing buttons like [Current] or [Battery] doesn't change anything on the screen. If you turn off the device, you will see that the changes are reflected. So. the charger SEES that you have pressed the buttons. It's not known if it's actually waiting for the loop to complete to change settings or not. I would like to be able to change settings while the device is charging, but. and the description said there is an updated manual that you can download to make up for the attached broken English manual. I couldn't find this download anywhere, so I can't say if it's better or not. I charged several batteries with it and everything works as expected. And I love the fact that you can turn off the charger if the battery voltage is too far out of range. Most automatic chargers simply won't work if they don't "see" the battery. Because it doesn't have and doesn't need a high-current "start" mode, it's lightweight. All in all I would recommend this.

Pros
  • Cool product
Cons
  • Something different
