[4-Pack] 12V 750mA Trickle Charger for Car Battery, Automatic Smart Battery Maintainer & Float Charger for Motorcycle, Boat, Lawn Mower, Marine SLA AGM Gel Lead Acid Batteries

Work as described. Very easy to use. Nice design and good cord length. Decent price for 4 chargers.

I love these chargers! But I love tools, so there's that. Used them all last winter. They work fantastic!

Loved these so much I bought another pack to addd to all my equipment, never worry about a dead battery again and really inexpensive

These are great for use on cars etc. Don't drive much so keeps my battery charged from lack of driving. Watch for sales as price goes up and down. I've ordered these a few times. Only downside is the clip ends can come loose or come off if you pull them too hard. They can be re-soldered if you have the means.

I have 16 or these now and they keep the batteries up to charge over the winter. They work great.

I purchased this to use for my motorcyle, razor and 4 wheeler over the winter. The price is great for the product you get. My motorcycle came with a covered connection for a trickle charger and this came with everything needed to make the connection. My 4 wheeler and razor did not come with one wired in to the battery but these trickle chargers do! I was able to make the connection right to the battery and run the adapter right beside the seat so I dont even have to take the seat off to attach the charger. Again, everything I needed to this came with the chargers! I've been using them for 2 months now and they have kept perfectly.

Great for many batteries

These are great little cheap 12v lead acid battery chargers. I use them for charging sealed lead acid batteries like you find in uninterruptable power supplies (1290's and such).They work great as long as the battery is disconnected from the load, bringing them up kindly to full charge and then "floating" or "maintaining" them at charge indefinitely.What doesn't work is if your battery is still connected to any sort of load. My guess is that the 750ma rate is just too slow to keep up with even tiny loads, so any load on the battery constantly pushes the charger back into "charge" mode.So if you want to charge a battery that is still connected to a load, you might look for a stronger charger. These are great for charging batteries "offline".Don't get me wrong, you CAN charge a battery even when it has a small load, but you'll probably see that it is always "charging" and never getting to "maintenance" mode, which may or may not be great for the battery. I'm not sure.

Especial para los vehículos que no usamos a diario así cuando ocupamos usarlos no tenemos problema de descarga de batería
