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

I replaced an old battery charger with this unit. Wow this thing is smart and works well. Batteries have come a long way and a new battery charger makes good sense

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.

Very good quality.. Works as it should..

Easy to use The cables are a little short

Old battery charger wasn't working too good. This one was a great replacement

I bought this to replace another brand that failed right after the warranty ended. About 2 months after. While the two works the same way, I've had this one for a long time. I received this around Sept 2021. This charger has been used on some really dead batteries. Some I had to put jumper cables on just to get enough voltage for the charger to see it is connected. On a few occasions, it ran at the maximum current for several hours with the fan whirring away at full speed. It just kept charging until the battery was completely charged. When my other brand failed, I looked inside. It was cheap made. I haven't looked inside this one but to charge sometimes dual automotive batteries which requires running at the maximum current for several hours, plus still last well past the warranty, it has to be well made with some good components and a good design. I've only used the engine start feature a couple times. It did work. If it all possible tho, I'd recommend a proper charge. If in a hurry, it will start a modern car. May require two times for a good sized truck. Make sure you wait a bit between the two engine start runs. It can overheat the charger if ran to close together. Check the manual but mine wants a 90 second wait. If I needed another charger, I'd certainly buy another like this one. I'm very happy with the way this charges and the durability. It performs a safe charge and detects bad batteries very well.

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!

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...

Small and lightweight, works fine.
