The charger is fully automatic with reverse polarity, overcharge and short circuit protection.

When in maintenance mode, the battery is constantly monitored. If the battery voltage falls below 12.8-Volts ±0.2-Volts, the bulk charge mode will restart to charge the battery at a constant 750mA until fully charged, then the charger automatically switches back to maintenance mode, which repeats indefinitely allowing the charger to stay connected worry free. The charger/maintainer comes with a five-year manufacturer's warranty. Review: BIKEMASTER BATTER MAINTAINER/CHARGER - To use a line from a recent movie, "So far, so good." After years of storing my motorcycle (in my garage, at least) during the winters (here in Nebraska where it can get below zero degrees Fahrenheit) and having the battery run down and then needing to be charged before I could start the bike and ride it, I finally bought this maintainer/charger. It hooked up to the battery easily and I could mount the charger pretty easily to a shelf fairly close to the bike. The charger indicates (by red light or green light) when it's charging or when it's charged. I've started the bike a few times since then in about 20 degree weather and it's fired right up. So, I haven't owned the charger for very long, but so far, so good. Based on my short experience with the charger, it works well and is not expensive. Review: Small, convenient trickle charger - Small, convenient trickle charger. You can travel with this which is great. ## Features - The BikeMaster Charger/Maintainer 750MA is perfect for keeping all of your 12 volt lead acid batteries in top condition, including: Conventional Acid Batteries (Wet), Factory Activated Maintenance-Free Batteries (FA), Absorbed Glass Mat Maintenance-Free Batteries (AGM) and Gel Batteries (Gel Electrolyte). ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B011J16WK0 | | Amperage | 750 Milliamps | | Best Sellers Rank | #1,348,885 in Automotive ( See Top 100 in Automotive ) #2,231 in Battery Chargers | | Brand | BikeMaster | | Built-In Media | Tool | | Color | Black | | Current Rating | 750 Milliamps | | Customer Reviews | 4.4 out of 5 stars 170 Reviews | | Global Trade Identification Number | 00887337251370 | | Input Voltage | 12 Volts | | Item Type Name | 750mA Battery Charger/Maintainer | | Item Weight | 9.6 ounces | | Manufacturer | BikeMaster | | Mfr Part Number | TE4-0237 | | Model Number | TE4-0237 | | Number of Ports | 1 | | Output Voltage | 12 Volts | | UPC | 887337251370 | | Unit Count | 1.00 Count | | Warranty Description | 1 Year | ## Product Details - **Brand:** BikeMaster - **Color:** Black - **Item Weight:** 0.6 Pounds - **Output Voltage:** 12 Volts - **Input Voltage:** 12 Volts ## Images ![BikeMaster Battery Charger/Maintainer - Image 1](https://m.media-amazon.com/images/I/810wtwm44-L.jpg) ## Questions & Answers **Q: Can I leave it connected all winter?** A: My battery charger/maintainer is always connected to my motorcycle from about September through about May. It may or not be connected when the weather is consistently 60 degrees or warmer, since the bike starts without the battery needing to be charged when it's warm. Cold or really cold weather really seems to take a tool on motorcycle batteries. I will also say that it's very easy to use the charger, meaning that mounting it on a surface is easy and connecting the leads to the battery itself is easy. **Q: Will this work to charge a batter that is completely dead? I've hooked it up to the batter in my motorcycle, but the light is not coming on.** A: It appears the battery may need replacement if no light comes on when you connect it to the charger. **Q: What size fuse is needed for this charger?** A: I'm not sure I understand the question. I just hooked the charger up to my bike without worrying about the fuses on the bike. **Q: I just received this and can't seem to get it working. The charging light will not turn on. Any ideas on if it is a dud or is it something I'm doing?** A: I’ve had this happen a few times and ended up exchanging the battery maintainer. It WAS NOT because the battery was dead. I tested them on several batteries before returning. ## Customer Reviews ### ⭐⭐⭐⭐⭐ BIKEMASTER BATTER MAINTAINER/CHARGER *by B***S on December 21, 2021* To use a line from a recent movie, "So far, so good."
