Battery Tender Plus 12V 1.25 AMP Car & Motorcycle Battery Charger and Maintainer, Float Charge for Automotive, and ATVs - Smarter Than a Trickle Charger

Highly recommend the Battery Tender Plus 12V charger and maintainer. I currently have two of them and will probably end up buying a third—they’ve been that reliable. They do a great job of keeping batteries charged and maintaining battery health, especially for vehicles or equipment that sit for periods of time. It’s really helped extend the life of my batteries and saved me money in the long run. They’re simple to use, dependable, and just work exactly as they should. If you’re looking for a solid battery maintainer, this is a great choice.

Absolutely awesome product, used on my 2026 Harley Street Glide. I've never owned anything so easy. Plug in and forget about the rest.

I was not driving my car far enough distances for the alternator to recharge the battery. I purchased this and at first thought it was not enough amperage to recharge my battery as I had left it on charge for 12 - 20 hours and the battery was still not fully charged. However, the battery was just really low as it did end up charging it all the way to full. And now when I plug it in, the next morning the battery is back to full. Very happy with this!

I was impressed with the packaging, the easy-to-understand instructions, the quality and simplicity, but then I thought it wasn't working properly and feared it would over-charge my new battery (due to some 1☆ reviews I read). My situation: we have a spare vehicle we only use once a month and then only drive short distances. After killing a 2 yr old battery, we got a new battery and our mechanic suggested a battery tender for this vehicle so I bought this. We had a new battery in the car. I hooked this up to the battery and it showed a red light for over 5 hours (meaning it's in charging mode). After the battery is at 80%, it's supposed to flash green, but after 5 hours it was still. So I unhooked it and hooked up our regular battery charger and it showed the battery was fully charged. I hooked the battery tender back up and it still showed solid red (charging) for another hour. Fearing it might fry my new battery, I disconnected. I decided to try it on my other car. I hooked up reg battery charger to other car and it was about 75% charged so I hooked up the battery tender and it showed solid red (charging) like it should and I went to bed. In the morning it was flashing green and then went to solid green indicating fully charged. So at this point, it's operating exactly as it should. So I hooked it back up to the first car. Back to solid red, but about an hour later, flashing green and then solid green now. So I'm not sure why it stayed red for so long on my new battery (that showed fully charged on my battery charger) but it seems to be working great now. Will update my review if anything changes as I plan to keep this connected full time until such time the vehicle is needed and repeat.

Very well built. This will save my battery while not in use for a month

Purchased this battery charger for my H/D and worked perfect. I now use it for my Duramax diesel truck periodically to keep the battery at full charge after too many short trips. Moved to Texas and with the heat and winter cold I use it at least 2 times monthly to top off my batteries and keeping them charged to proper voltage. This charger has been through a lot moving but always worked. Very sturdy metal case. 4 stars because it is getting old in design but so am I. 15 yrs old still working!

Great product; easy to use!!

Quality product and fast delivery. Item is exactly as advertised. Works great 👍

This thing does what its supposed to do. I bought it to tend the battery of my '78 Corvette while I stored it for the winter and it did just that. super easy to set up with a "set it and forget it" type of functionality. my battery was flat when I plugged it in and within 24hrs or so it was fully charged and remained charged for months when I was ready to reinstall it into the car. 5-stars!

I bought this one from AMAZON.AE. However the charger is not proper for use in UAE because of the difference of working voltage. This charger works only on ~110 volts. However in UAE, the voltage is about ~220V. The charger i bought was damaged when being plugged into the outlet.

This charger is perfect for all batteries on vehicles and easy to fit. The only point I would like to make is that on the description it does not mention that it is 120v. I had to buy a voltage dropper which was not an issue apart from the fact that had I been aware I could have ordered that at the same time

Buen producto

Product is 120V only, with a US-style mains connector. This has been deliberately mis-sold into the UK market via amazon.co.uk (the clue is in the name!). Stop listing this product in unsuitable markets, otherwise you're unnecessarily increasing your carbon footprint and wasting everybody's time and money.
