I set up this 200Ah battery to power a 2500 Watt Sine Wave inverter to use as robust UPS system for all of the power sensitive computers and other electronic devices in my house. The problem I discovered was that the inverter's LCD display would eventually draw down the battery after 5 or 6 days to the point that the inverter would sense the voltage falling below 11.8Vdc and shut the unit off. If I didn't notice that, the unit would not be ready for a power outage and defeat the entire purpose. The Battery's BMS (Battery Monitoring System) circuit that is built in to the battery, keeps the charger turned off until it reaches somewhere below 11.8Vdc. So the charger never turns on by itself unless you cycle the power. I programmed this timer to run in the on state for 36 hours and then off for 5 seconds which will now restart the charger and brig the battery back up to 14.4Vdc where it is fully charged. When fully charged, the BMS circuit tells the charger to turn off, which it does. Works like a dream. No more caught off guard with a low or dead battery from the system sitting idle. The instructions were a little confusing, but just play with the buttons a little and it soon becomes easy to understand how it programs with no problem. One down side to warn you about which is not an issue for my application; It's advertised to have memory backup, which it does in that if you unplug it, it remembers your programming scenario. However, after power is restored, it starts the originally programmed time cycle all over again instead of continuing from the point of elapsed time before the power failure. In my application, it is beneficial that upon any power failure, I will want my charger to cycle and bring the battery back up immediately. Prior to finding and using this product, I would have gone to the trouble and expense to use two 12Vdc timer boards, one for the 36 hour time delay and the other for the 5 second cycle off combined with 120Vac plugs and receptacles to perform this task instead of this all in one self contained, safe and waterproof plug and play unit. The unit seems very well built and waterproof for outside use. I highly recommend this product! Hope this helps. Review: Precise seconds interval suited my needs - Works great. It was easy to program and confirm settings. Seems durable and high quality. It's been reliably switching off/on a grow light that is connected to another separate standard weekly timer. I have this Techbee repeat interval cycle timer set to remain on all day and quickly switch off/on for just two seconds shortly after my existing weekly timer switches on a plant grow light each day. That grow light has three different color modes designed to affect growth. My plant light modes can only be changed by depressing a foot switch on/off/on/off/on/off in sequence. I'm using this cycle timer to simulate a manual off/on toggle foot switch that switches through the plant light's three color modes. I now have my plant light automatically switch on, and once on, this repeat timer will automatically switch it off/on for two seconds so it advances to the next light mode in the off/on toggle sequence. With a short off/on 2 second setting, I can now manage my plant light automatically. It's very flexible and has precise programmable timing. I also like that it's water resistant as it sits right below my plant. ## Features - Customizable Continuous Intervals: the on and the off repetitive intervals can be as short as 1s, and as long as 999 hours (about 41.5days), more flexible for your different needs.Please note: this timer doesn't allow programming based on actual time. - 3 Cycle Modes: the on and off interval cycle you set can be set to run infinitely(24/7), or to run only during the day or only at night for different purposes. - 4 ON/OFF Modes: always ON/OFF mode allows you to manually override the timer; allows quick set to on from dawn to dusk, or on from dusk to dawn. - 2 Countdown Modes: The countdown from dusk/dawn allows your devices to start automatically at dusk/dawn every day, run for the set duration, and then stop completely. - Safe to Use and Widely Used: weatherproof design for safe use outdoor and indoor; widely used on all kinds of electric pumps, lights, fans, heaters and humidifiers. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09BZ8LQFB | | Best Sellers Rank | #18,923 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #25 in Plug-In Timers | | Brand | Techbee | | Brand Name | Techbee | | Color | Black | | Customer Reviews | 4.4 out of 5 stars 550 Reviews | | Item Dimensions D x W x H | 1.2"D x 4.8"W x 1.9"H | | Item Type Name | Cycle Timer | | Item Weight | 0.5 Pounds | | Manufacturer | Shen Zhen He Yi Ke Ji You Xian Gong Si | | Manufacturer Warranty Description | 1 year. | | Material | Plastic | | Material Type | Plastic | | Model Number | TC201 | | Number of settings | 13 | | Product Dimensions | 1.2"D x 4.8"W x 1.9"H | | Smart Home Compatibility | Not Smart Home Compatible | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Techbee - **Color:** Black - **Item Weight:** 8 ounces - **Material:** Plastic - **Product Dimensions:** 1.2"D x 4.8"W x 1.9"H ## Images ![Techbee 1 s to 999 h Short/Long On-Off Interval Repeat Cycle Timer Plug Outlet with Countdown and Light Sensor, Waterproof for Outdoor (15A 1HP) - Image 1](https://m.media-amazon.com/images/I/716mk-0TFQL.jpg) ![Techbee 1 s to 999 h Short/Long On-Off Interval Repeat Cycle Timer Plug Outlet with Countdown and Light Sensor, Waterproof for Outdoor (15A 1HP) - Image 2](https://m.media-amazon.com/images/I/81yrK47UecL.jpg) ![Techbee 1 s to 999 h Short/Long On-Off Interval Repeat Cycle Timer Plug Outlet with Countdown and Light Sensor, Waterproof for Outdoor (15A 1HP) - Image 3](https://m.media-amazon.com/images/I/81L51E2ptxL.jpg) ![Techbee 1 s to 999 h Short/Long On-Off Interval Repeat Cycle Timer Plug Outlet with Countdown and Light Sensor, Waterproof for Outdoor (15A 1HP) - Image 4](https://m.media-amazon.com/images/I/81nWAhsWfdL.jpg) ![Techbee 1 s to 999 h Short/Long On-Off Interval Repeat Cycle Timer Plug Outlet with Countdown and Light Sensor, Waterproof for Outdoor (15A 1HP) - Image 5](https://m.media-amazon.com/images/I/81jgsIA2-RL.jpg) ## Questions & Answers **Q: Why is the screen of the timer I received blank and unable to be set up?** A: This timer requires being plugged in for use and setup. It can be set up normally once it is powered on. **Q: Can I set the current time on this timer? And does it do daylight saving time?** A: No, you can’t set the current time or adjust for daylight saving time with this timer. It’s a cycle timer that works on short or long intervals. If you do need to set the current time, you can check out another model we have—T319. **Q: Does this timer retain programmed settings during a power outage?** A: Yes, even in the event of a power outage, the timer will retain its programmed settings. Please note that once power is restored, the timer will resume the program based on the state just before the outage. **Q: Is this timer waterproof?** A: Yes, it’s waterproof in structure and material. However, please make sure the nuts are snugly tightened onto the timer’s bolts for 100% waterproofing. For outdoor use, mount the timer vertically and position it at least 2 feet above the ground. **Q: Why isn’t it working as programmed?** A: The light sensor has a 12-minute delay to prevent interference from light sources like flashlights or car headlights. Also, if you use the light-sensing function indoors, please make sure to keep it away from light interference. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great, just as advertised. *by A***R on April 1, 2026* I needed a timer that could be programmed to cycle off a battery charger for a few seconds so that it would restart once every three days to keep a 200Ah LiFePO4 battery charged.
