Lithium for car amps** A: No. Lithium batterie$ need a $pecific charge controller. ($$$) **Q: does the blue light stay on** A: The blue light indicates that the primary battery is connected to the alternate battery and charging. This happens when (1) the vehicle's ignition is on and (2) the primary battery is being measured at 14V or higher. Also, after turning off the ignition there is a delay of less than a minute before the batteries are isolated. The blue light will remain on until completed **Q: i bought this three months ago. the battery continues to drain. always stays at 11.7 v. i dont know if thing is broken or what. what do i do?** A: I would not continue to let the batteries drain to 11.7 Volts. Never let you battery bank get lower then 11.9 Volts. I would replace your battery isolator. **Q: Can I use this with a 200 amp alternator or will it hurt the unit** A: This unto will work fine. Your alternator may be rated for 200 amps. That rating is right before is burns up. There are other loads in your car that will take power while it is running. There is no way your alternator will push 200 amps to your battery. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Battery adupter *by S***I on 23 January 2026* Good product and useful ### ⭐⭐⭐⭐⭐ ممتاز جدا جدا *by R***D on 15 May 2024* هذا المنظم تستطيع أن تقوم بتركيببه لوحدك حيث أنه ينظم الشاحن بين البطارية الرئيسية والبطارية الإضافية وله ميزات أخرى ### ⭐⭐⭐⭐⭐ ادهش اني هذا المنتج رائع جدا *by K***D on 21 November 2023* ممتاز ## Frequently Bought Together - WirthCo 1213.1241 20092 Battery Doctor 125 Amp/150 Amp Battery Isolator , Black - TKDMR 10pcs 1/0 AWG-3/8 Battery Lugs,Heavy Duty Wire Lugs,Ring Terminals,Battery Cable Ends,0 Guage terminals,Battery Terminal Connectors with 10pcs 3:1 Heat Shrink Tubing - Hamolar 3 Pack Car Audio 150 Amp Resettable Fuse Circuit Breaker Car Protect for Audio System Fuse 12-48V DC for Car Audio Amps Overload Protection Fuse --- ## 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/254791521-wirthco-20092-battery-doctor-125-amp-150-amp-battery-isolator](https://www.desertcart.tn/products/254791521-wirthco-20092-battery-doctor-125-amp-150-amp-battery-isolator) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-18*
