I have 32 golf cart batteries for my off-grid home and after having them for 2 years I saw that they where loosing strength but with the BLS wow they are back like new. I can do a lot more loads and they are taking the beating like if I had just bought them. Highly recommended. I was planning on getting lithium batteries but not anymore, these lead batteries will last longer with the BLS. once you install it you have to wait around 2 months to see the difference and you will for sure. Review: Battery maintenance - Easy to install, seems to be working well but only time will tell. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B006X1Y1BY | | Best Sellers Rank | #2,314,772 in Automotive ( See Top 100 in Automotive ) #3,238 in Battery Chargers | | Brand | BLS | | Connector Type Used on Cable | Ring Terminals | | Current Rating | 250 Milliamps | | Customer Reviews | 4.2 out of 5 stars 48 Reviews | | Input Voltage | 120 Volts (AC) | | Item Dimensions D x W x H | 2.5"D x 2"W x 2"H | | Manufacturer | Battery Solutions & Innovations, Inc. | | Mfr Part Number | BLS-48A | | Model Number | BLS-48A | | Output Voltage | 48 Volts (DC) | | Product Dimensions | 2.5"D x 2"W x 2"H | | Specification Met | energy | | UPC | 610074901112 | | Unit Count | 1.0 Count | ## Images ![Battery Life Saver BLS-48A 48v Battery System Desulfator Rejuvenator - Image 1](https://m.media-amazon.com/images/I/41Y9BtH0hTL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing!!!!! just saved me BIG $$$ *by J***A on December 29, 2020* I had heard that these things did not really work but the system works wonders!!

It took longer than they projected, but it really works. My cart went from being very slow, even after an over night charge, to one that jumps when I press the accelerator. Well worth the investment. I batteries are approx. 5 years old. --- ## 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.tn/products/7967416-battery-life-saver-bls-48a-48v-battery-system-desulfator-rejuvenator](https://www.desertcart.tn/products/7967416-battery-life-saver-bls-48a-48v-battery-system-desulfator-rejuvenator) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-23*
