Review: Great little smart charging unit. - This my second Tower Top smart charger for my RV. I've been using the Tower Top to keep my batteries charged because the charging part on my inverter went out and we have been busy moving around until we get back to home base where a new inverter/charger is waiting. I connect to my batteries plug into one of the outlets at the RV park wherever we may be and let the unit do it's thing. It's auto sensing, which is great and charges my batteries great. I definitely recommend this little unit. Very easy to use. 👍
Review: no on off toggle switch - 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 desertcart 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.

## Features

- 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 deep-cycle and lithium (LiFeP04) batteries, as well as 6V and 12V lead-acid batteries, including STD, AGM, GEL, Wet, MF, EFB, and calcium 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.

**Q: Are the clamps large enough for full size top post batteries with fittings?**
A: Hi Lawnman73, the battery charger is equipped with full-wrapped pure copper battery clips with 1.38-inch (35mm) openings and firmer covers.
