24/7 Pre & After Sales Support

Efficient, Energy-Saving, and Fast Charging: The TowerTop Trickle Charger offers 4 adjustable current settings (2A/15A/25A/AUTO) to meet your diverse needs. With a max charging current of 25A, you can fully charge a 100Ah battery in under 3.5 hours. Achieving an 85% charging efficiency (industry average 75%), this charger is more efficient, increasing charging speed by 1640% compared to 2Amp chargers. Not only is it energy-saving, but it also saves you a significant amount of waiting time
Fully Automatic Charging: The charger automatically recognizes charging. If you forget to press the start button, it will start charging after 30 seconds. Once fully charged, it switches to pulse repair mode and turns off the screen to save energy, maintaining the battery at a safe voltage level for long-term storage. When the battery voltage drops too low, the charger automatically restores full output power and switches back to pulse maintenance mode after reaching full charge
All-in-One Compatible Design: Designed for 6V and 12V sealed lead-acid batteries in cars, boats, RVs, power sports, and deep-cycle batteries, including 12V calcium and lithium (LiFeP04) batteries, as well as 6V and 12V lead-acid batteries, including STD, AGM, GEL, Wet, MF, EFB, and deep-cycle batteries. The charger also has a memory function to remember the last settings, ensuring uninterrupted charging even during long-term use without worrying about power outages
HD LCD Screen and 8-Stage Intelligent Charging: With true 8-stage smart charging (desulfurization, soft start, bulk charge, absorption, analysis, repair, float, and pulse maintenance), it optimizes battery life and repairs batteries without overcharging or damaging them. The HD LCD screen allows you to view the charging stage and parameters at any time, keeping you informed of the charging status.
Battery Repair: Independent desulfurization and repair buttons allow you to manually desulfurize and repair your battery to restore lost battery performance, helping to revive old/idle batteries and extend battery life. If your battery cannot be charged, you can try the "repair" mode to fix it. Note: It cannot repair completely drained batteries.
Engine Start & Winter Mode: Engine start delivers 100A current helps activating your car battery to start your vehicle in 100 seconds. Winter Mode, +0.2v on the basis of the original charging voltage, better boosts your battery activity and charges more thoroughly in low-temperature situations.
Multi Safety Protection & ETL Certification: The charger provides multiple protections to ensure safe use, including spark-proof, reverse polarity, overcharge/discharge, overvoltage, overcurrent, overload, overheating, current backflow, short circuit, etc. The upgraded cooling system improves performance. ETL certification makes it safe to use.

Title: Big upgrade on the old-time battery chargee
Review: This is a big improvement on the charger I bought some 20 years ago. It's actually a charger while the old one just kept your boat batteries charged over the winter. It has many added features, which is great. What's not so great is the instruction manual. It tells you what the various functions are but does not give you any understanding of why you would use that function and in what sequence relative to charging the battery. I searched YouTube and others for a demonstration of the charger but there are no actual applications, mostly unboxing. The manual is pretty much for the true auto mechanic.

Title: no on off toggle switch
Review: I purchased this mid October 2023. Review is almost one year of use, now end of August 2024. I use this to trickle charge the battery on a 25+ year old vehicle that loses electricity sitting in the driveway, because I hardly ever drive it. I use this device to make sure it is topped off every couple of weeks. If I drove my car daily, or at least once per week, I would not need the trickle charger. Before I purchased this conditioner, I had left my car unattended for a couple of months. Saw it on Amazon and thought I'd give it a try before having to buy a brand new battery for my old car. This device at first indicated that my car battery was unable to charge as a 12 volt car battery. Luckily this battery charger was able to step down and charge it as if it was a motorcycle battery. I thought I'd try that and get some juice into, before opting to buy a replacement battery. After a day of recharging from the lowest setting, I was able to recondition the old car battery back to life, restart the car, and be able to drive more than 100 miles on the recharged battery. Now I use it often to make sure my unused car keeps it's charge when I'm not driving it. I just wish that the unit had a physical on off toggle switch. Instead the on off of the device is by plugging it into the outlet. It's recommended to be used directly into a wall outlet and not into a strip surge protector. I use a heavy duty 10 gauge extension cable and a GFCI adapter that has an on off physical switch on the GFCI outlet for extra protection. The other thing that you have to be careful with this charger is using it when the weather is bad. Make sure you do not use this when it is raining. This trickle charger is a slow charger, which I like. It may take awhile for it to charge up the battery, maybe a few hours, depending on how depleted your vehicle battery is. I tend to not wait for the charger to reach full capacity of the battery. I charge it to 3/4 of fullness to make the battery last longer. YMMV. Overall, this battery conditioner has been a life saver.

Title: Far more than just another battery charger!
Review: I had a completely dead, high dollar battery in my Vette. This unit brought it back to life and repaired it. I had it tested with a handheld meter and the results were bad battery, replace. So, I ordered this based on the features it offered, and it worked like a charm. Next, I hooked it up to the battery in the truck and let it do its thing and wallah. Truck now starts quick just like it did the day I bought it. I read some reviews that said it would not work if battery was dead. At first, I had the same problem, but I moved the clamps from the small side post terminals where the cables screw in and attached them to the large posts on top. She came to life, and automatically detected it was an AGM and went to work. I highly recommend this unit and very happy with my purchase.

Review: I have a brand new H8 AGM that went low at -40. My 30+ year old charger just didn't work for it.This restored the battery to full charge in short order once I figured out how to swap it from 6 to 12 volts. Funny how after reading the manual things are not as clear outside in the dark with a flashlight at -20 trying to get it working.The plastic construction seems a bit fragile and might not stand up to rough treatment.My real concern is the manual says the working temperature is from 0 to 40 DegC. Well, I will probably never need it above 0 DegC. I used it at -20 and it worked fine, but the plastic construction might not like to be stored in the cold. I will store it inside in a warm atmosphere instead of the garage.Would be nice if the ad mentioned the temperature range and if it just should be stored in a warm place so it is warm when you start it or if it should never be used below freezing... that is a consideration for most of us.

Review: This is a really great Smart Battery Charger. I wanted an electronic copy of the manual (in addition to the manual that came in the box) and after sending a quick email to TowerTop, their Customer Service team responded by sending me the pdf version of the manual within hours of my email.
