TowerTop 2/10/25 Amp 12V Smart Car Battery Charger, Fully Automatic Battery Maintainer with Engine Start, Auto Desulfator, Battery Repair, Winter Mode, for AGM, STD, Gel, Deep Cycle Batteries

This is a life saver, my car hasnt been able to start after this cold bite my state has been dealing with. I bought this and after the first engine start jump with this guy it started right up. By far the best investment I've done for my vehicle.

Great little charger I use it to start my lawnmower and anything else. I love that it already knows what battery is in for the money.

This unit works perfect for my needs. I wanted not only a charger but also a maintainer and is simple to setup and use. It came with battery clamps for charging, a pigtail for battery maintaining and a 12 volt socket if you want to use it as a power supply.

like: work as intended I am satisfied with using this device but not sure if my time was limited how handy this particular device dislike: the plastic on the red clip feel out as I open the box will not charge a totally dead battery not sure how long will this last note: doing repair on cars may cause some manufacturer warranty to be voided also weather condition was cold and snowing. could had been a 5 star but I had issue with this device stated in dislike. the clamps were too big to connect to the battery terminals (this is my major issue) My battery was a duralast gold 75-DLG, I had no idea what type this is so I set this device to "standard". 1. battery was dead and this device does not acknowledge that the clamps were connected so I connected a 12v 3a power source and let it charge for a couple of hours. 2. after disconnected everything and connect this device. the "charge" did not work so I pressed the recondition, left at that point for 3 hours. 3. turn the power off and on. pressed the "charge" button. the indicator said "60%". left it overnight. 4. I came back in the morning and check the device condition, it was off. my MMV indicated a charge of almost 13v. car started with no issue. Added note: the red clamp will not clip on positive terminal. The black will sometimes slip off the battery black terminal. update - may 4, 2021: yesterday the car battery I have been using this item had a voltage level of 11.0 v. Recharge did not work, tried it several times. I tried "recondition", it seems to work on the battery. This morning this item finished and the voltage measured at 12.7v. The battery I have been work would max out at 12.9v. The 0.2v difference is a drain from the car alarm. Also I bought "uxcell 10pcs 100A Red Black Battery Insulated Test Clips Alligator Clamps Clip for Car" to replace the alligator clip because it would not clamp around the positive side. It was not the best but work. A light bump on the clip would dislodge it.

This smart charger offers reconditioning of neglected batteries and even continuous battery health for those winter storage days. I have multiple pieces of equipment and replace batteries every spring. It will service multiple battery styles including Gel. This charger works of AC or DC and comes in really handy in the field when there is no electricity available. User friendly and simple control panel. I couldn't be more satisfied.

This charger is just what I needed. Has everything for maintaining battery life at all times. Very lightweight compared to many other chargers I have had.

Easy to use, works perfectly

Yes, I like this charger - I've been using it since July. However, I had not taken the time to write a review. Now that I have experienced their customer support - well let me tell you about that. Like I said I've been using it since July. Not just once or twice. I have several vehicles, 3 riding mowers, 2 French hens - oops - I have a lot of stuff that uses 12v batteries. About a week ago, I plugged in the charger and nothing. No screen, no hum, no response at all. After determining what ever was wrong was beyond me I contacted customer support. Two emails later and I am sitting here today with a brand new charger, shipped next day air. And between my initial contact and today I have received several unsolicited follow-up emails, they were just checking back to make sure things were happening as planned and that I was happy. Yep, I'm happy. Great charger, outstanding customer support

Great device! Saved 4 of our vehicles' batteries from needing immediate replacement. There are two large batteries in my '93 diesel pickup. They cost about $300 each these days, so I'm trying everything I can to not fork out over $600. Essentially, this is to charge them up and experiment whether I have a parasitic drain or whether my battery just doesn't hold a charge. Worth spending $100 to diagnose rather than $600 and maybe still have the same problem. It is not a jump starter however, so I did purchase an Amplyn jump starter for a 10 l diesel (even though mine is 6.3 l) for around $100 and also purchased a multimeter for about $20 and now I feel like a professional mechanic, lol. I am far from that, but if I can take basic issues into my own hands and not pay $90 an hour then that's a win!

Delivery was very quick and the item is as described.

Excellent battery charger in all respects, versatile with multiple amp settings, well designed and made....I would recommend this model for anyone who needs a quality battery charger for multiple vehicles...

I found this to be a reasonably priced charger to top up my large L16 solar batteries from my off grid cabin over the winter months. I pull them out every winter and top off the charge over the course of the winter. As they are 6v, i put two together and works great. I have tried the battery recondition without success but the batteries I tried on were far gone so not sure anything could have helped.

does charge the battery very wellandtell you if battery is no good
