Featuring patented high-frequency pulse technology, it prevents sulfate buildup, avoids overcharging, and continuously monitors battery health with microsecond precision. Weatherproof and UL listed, it’s ideal for marine and automotive use, ensuring your batteries stay fully charged and ready whenever you need them. ## Description 12V batteries need a little TLC from time to time and if they are neglected or used infrequently they can die. Avoid that unpleasant fate by getting a BatteryMINDer. This cool tool maintains all sizes and types of 12V batteries, including sealed, marine and deep cycle, up to 4 at a time. It uses patented high-frequency circuitry to dissolve harmful sulfates, extending battery life and performance. It never overcharges and is weatherproof to withstand rain and marine environments. UL listed. ## Features - Full-time battery monitoring automatically tests battery every microsecond, supplying only the current needed to maintain battery at full charge - Maintain up to four 12 Volt standard, starting batteries (of similar type - in parallel). Amperage is divided evenly among connected batteries. (NOT recommended for deep cycle batteries) - Does not overcharge, regardless of time connected - High-frequency pulses safely remove sulphate from battery's plates that prevent the batteries from holding a full charge - Adding water references Wet typed batteries. If the water level isn't sufficiently maintained, charging the battery runs the risk of overheating and cooking the battery. The charger applies current to the battery and this can cause the water to boil and evaporate. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | BatteryMINDer | | Brand | BatteryMINDer | | Package Dimensions | 21.84 x 17.02 x 8.38 cm; 929.86 g | | Item model number | 12117 | | Manufacturer part number | 12117 | | Voltage | 12 Volts | | Item Weight | 930 g | ## Product Details - **Brand:** BatteryMINDer - **Item weight:** 930 g - **Output voltage:** 12 Volts - **Specification met:** UL - **Current rating:** 1.33 Amps ## Images ![BatteryMINDer Model 12117: 12 Volt 1.33 Amp (12V 1.33A) Charger/Maintainer/Desulfator - Image 1](https://m.media-amazon.com/images/I/71S0QOE0PLL.jpg) ![BatteryMINDer Model 12117: 12 Volt 1.33 Amp (12V 1.33A) Charger/Maintainer/Desulfator - Image 2](https://m.media-amazon.com/images/I/61fgZ79IMXL.jpg) ![BatteryMINDer Model 12117: 12 Volt 1.33 Amp (12V 1.33A) Charger/Maintainer/Desulfator - Image 3](https://m.media-amazon.com/images/I/61P1OUfSp7L.jpg) ![BatteryMINDer Model 12117: 12 Volt 1.33 Amp (12V 1.33A) Charger/Maintainer/Desulfator - Image 4](https://m.media-amazon.com/images/I/6101gqug+eL.jpg) ![BatteryMINDer Model 12117: 12 Volt 1.33 Amp (12V 1.33A) Charger/Maintainer/Desulfator - Image 5](https://m.media-amazon.com/images/I/618oet3x-dL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/51572948-batteryminder-model-12117-12-volt-1-33-amp-12v-1](https://www.desertcart.us/products/51572948-batteryminder-model-12117-12-volt-1-33-amp-12v-1) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-26*
