BMK 12V 2A 4A 8A Smart Battery Charger Portable Trickle Battery Maintainer with 7 Stages Fast Charging IP64 Waterproof Trickle Charger for Car Boat Lawn Mower Marine Sealed Lead Acid Batteries

This is an easy to use, well made charger/maintainer with good visuals and good documentation. My use for this charger is to maintain the battery in my lawn and garden tractor and so far it has done an excellent job of keeping the battery fully charged and operational. At this time (because the situation has not presented itself) I cannot speak to the abilities of this unit in bringing the battery back up from a discharged condition where the battery is sufficiently discharged to the point of being unable to allow for starting the engine.This unit provides mounting holes so that it can be affixed to a convenient location either on the vehicle or to something near the vehicle. My application uses the latter. I appreciate that the unit is water proof but that is not a consideration for my application. The connection wiring is excellent but it would have been nice if the wires had been somewhat longer. Also, it would have been nice if the unit had included a wiring section that provided eyelet mounting to the battery connectors. The eyelet connector would have made it a simple task of connecting and disconnecting the charger unit via the harness connectors as opposed to always having to use the included battery clips. While both the length of the included cables and the eyelet connector can be resolved by purchasing them separately it would have been more convenient had they been included.Now that I have had a chance to work with this unit I plan on buying another for an additional application.Overall, I rate this unit as excellent.

This battery never worked for my friend. I gave it as a gift and now can’t return it due to the time span which I never realize. Be careful if you want to buy from this seller. Waste of money

Good product. Works well across many different capacity batteries. I use it for motorcycle and car batteries. It also works across the three major types of battery chemistries. Wet, AGM, and Gel.

Wired this charger into my motorhome, which gets intermittent use. It keeps the battery in Tip-Top shape so we're always ready to go on the next trip.

Works great!

Easy to use, purchased to charge my boat AGM batteries and Wet cell lawnmower batteries. So far does an excellent job and batteries have lasted longer. Would recommend this product.
