Battery Tender 4 Amp, 6V or 12V Selectable Battery Charger, New

Ive been using Battery Tender products sonce the 90s. Recently bought a Porsche and connected one of my older BTs only to find it never indicated a fully charged battery. After reading, I learned today's new batteries are of a different type, which this model handles. It 100% solved the problem. I connect it with a quick-connect lead that's permanently connected to the terminals. Works like a charm

Bought this to maintain my personal truck battery because I only drive it on the weekend and I was having a problem with a parasitic draw. I have since fixed that but still use it because why not? I bought a pig tail from Amazon to hardwire this up to my battery from the bumper. So I took the alligator clips off and the cable plugs right into the cable I wired straight to the battery terminals. I have a video but this app only allows

Lives up to my previous experience with the Battery Tender brand: but works with either 6 or 12 volt batteries and both charges and maintains them. This is relatively new, but if it maintains battery health for years st a time with infrequently used auto batteries as prior units it will be an ideal solution to battery maintenance in infrequently used batteries.

very convenient because not only is it a maintainer but a charger. i keep it on my corvette during the winter. battery is always ready to fire up after months of sitting

The battery tender keeps my battery charged while I am not using the car. On cold mornings it is nice to have that full charge when starting the car. I am so happy that I puirchased this item.

Easy to understand instructions. Unit has a long enough cord thankfully. Do wish that the clamps were slightly bigger to attach easier to battery terminals. Otherwise great unit I recommend.

Easy hook up with optional attachments. Easy to read, well designed with a hook to hang it or mount to a flat surface Indicating lights are easy to read

It works great and charges both of my 6-volt batteries. For large batteries like that, make sure to unplug and plug back in when it stops, by default, if your battery takes longer than 24 hours. It has a built-in stop after a long period.

The Battery Tender 4 Amp charger was connected to a 12V, lead acid battery in a car that was not driven for 2-1/2 months. After the charger was disconnected, the car started with no problem.

I don't know, since I never received the item I ordered, instead I received cat food and still had to pay to return, the wrong item. I decided to cancel the order and get it from Amazon and received it in a day.
