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

Well made product. I like the fact it will fix a very low battery. Screen is large enough anold man can read it. I have no problem with the clips. They are the size of most chargers. Great size overall and very easy to use.

I purchased this charger to replace my old charger that I had for 30 years. What a difference and upgrade to my tools for charging. Here are my observations. Pro: 1. [ Quick Charging] I love the 4-level adjustable current 2A/10A/25A/Auto setting. I can set the charger up to what I need whether I am charging a car battery, motorcycle battery, or tractor battery. 2. [ Fully-automatic Charging] The Auto setting is my favorite because I can setup and let it go. I would setup at the end of a night and let it go all night. It automatically shuts off and the battery is full charged. 3. [8-Stage Charging Program] The intelligent 8-stage charging works flawlessly in the auto setting. The best is the information it displays during the process. Works as stated. 4. [Engine Start & Winter Mode] I have used this mode twice. It provides 100Amps of charge. It helped my get my car started for work on a very cold morning. 5. [Overall performance] No complaints works as stated and meet my needs to dealing with all the batteries in the household. 6. [Price] Product is low price with high quality. Meets my expectations without breaking the bank. 7. [Durability] Case is well built and well mold to stand the dirt and grime of a typical garage. Cons: 1. [Case] A firm case would be nice for storage. Just using the box for storage. Could be an added item to improve the product. 2. [Screen] Screen is average quality for the product. Overall, I would rate this product as a 5 star. It meets my expectation of quaility, ease of use, value for the money and versatility. Excellent addition for normal household use.

This is a nice tool for what it’s designed for. It works well and is easy to use.

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.

Don't let the small size of this battery charger fool you. It's pretty powerful. It's actually smaller than a typical automotive battery. But it does the job. You choose the battery type and the power level that you want and hot start. It's a smart charger and will actually remember your settings. So you won't have to put in the settings you want every time you use it. I like the fact that it has several different functions including a winter mode where it puts out extra voltage that is needed to charge a cold battery. Which is the reason why I bought it. It has an engine start function as well which provides enough power to start your vehicle. Last winter, it got down to 2° degrees where I live which destroyed my battery last year. So I didn't want to go through that again. It charged the battery up very quickly and several other functions include a reconditioning mode as well as maintaining a battery in maintenance mode. It has a bright LCD screen that was so bright my camera wouldn't take a picture of the writing on the screen. Since I just recently purchased this unit, I can't tell about the durability of it but I will do that in an update at a later time but it's definitely worth the money that it will save you.

This is the second one I purchased. They have worked very well with lots of options.

I have had this charger for two years and it is my go to charger all the time. I do repairs on ATV's and SXS's. Almost every vehicle that comes in has battery problems. Recreation vehicles are used and then put away and then most of the time not touched until it's time to use them again. This charger has brought many of these batteries back to life that normally would need to be replaced. The recondition function does take quite a bit of time , but is well worth the results. The only down side is that the battery needs at least 3 volts for the charger to start working. If I have a battery under 3 volts, then I put an old manual charger on it for about 15 minutes. After that it will usually have enough voltage to let this charger start working. But that small inconvenience is worth what this charger can do. On a sad note, this charger recently blew up from my own fault. I was charging an ATV outside my shop while I was test riding another on my 22 acre property. Out of nowhere it started raining. I was to far away from the shop to get there quick enough to stop the charger from getting hit with the rain. I opened it up to dry it out and saw a burn mark on the plastic case where the water arced. I saw two burned resistors. I contacted Tower Top with the location of the burned resistors and asked them for the specs of the resistors so I could order replacements. They promptly answered back with just what I needed. Great Service from them! I have ordered the new resistors and hopefully that is all that was damaged and I can bring this unit back to life. In the mean time I have ordered the Pro Model which is above this model. It says it will work down to 1 volt in the battery. I am looking forward to the same great quality and service that I got out of the first charger. The only downside to this charger is the clamps. Sometimes the biting area is a little hard to make a connection in a confined area or on a smaller battery and the colored plastic clamp covers just clip onto the metal clamp and are not strong at all. They come off very easily. Just having the cable swing down while moving the unit and having them contact the floor, bench or anything can break off the tabs on the clamps plastic covers. This is the only area I can say needs improvement. But all the positives of this charger out weigh the weak plastic covers. I would highly recommend this charger. I will write a review of the Pro Model after I have some experience with it.

Received product well packaged,looks like a good product , read instructions and hooked it up to a battery that was partially charged with my 15 yr old Schumacher charger that failed mid charge with circuit board issues in which componets failed (capacitors, ic chips) melting the board beyond repair it was also an automatic charger that always worked flawlessly, this charger with its very poor instructions as well as operational lack of intuity leaves you wondering what it’s doing if any thing, when connected it displays a charge of battery reading (50%) yet it will not start to charge,if you read the instructions they say that this state of charge reading is inaccurate until its final float cycle that it won’t ingage?, so this is absolutely useless, it has a default setting of 2 amp charge on gel cell battery? Again worthless, if no manual selections are made the charger is supposed to read the battery and make the correct selections and start its charge ?on lead acid battery’s it selecting 2amp gel cell battery and won’t start the charge cycle, there is no information if the battery is fully charged or partially charged and nothing is running or lit to indicate anything is occurring, basically it’s been engineered by a moron like most items from china complete waste of effort and time returned for refund. Maybe it works? But not wasting my time to find out in 12 hrs it’s not? JUNK JUNK JUNK!

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!

Great battery charger. Works well.

Have recharged alot of batteries with this… even repaired some smaller batteries for 4 wheeler and snowmobile... havent been able to to repair any bad vehicle batteries

Arrived on time and right out of the box it was a no brainer to use just plugged it in and it went straight to work and charged my truck battery within few short hours. My truck has a parisitic current draw since recent body work and haven’t been able to locate it just yet so it can drain in a few days with out warning. Very pleased with the charger’s performance to top up other batteries in my toys as maintenance.

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...
