The BC1204 is a Four Stage Charger Stage 1: Desulfating the battery through 18V pulse. Charger enters this stage if it detects battery sulfation or severe discharge. Once battery is rejuvenated, charger moves to Bulk stage. Stage 2: Bulk charge using charger highest rated voltage and current for the type of battery in use until it reaches 80% capacity. Stage 3: Absorption, the output voltage is limited to 14.7V while current declines as the battery charges to its full capacity without overheating. Stage 4: Float.

This is a piece of garbage and I would give it zero stars if I could. ### ⭐⭐⭐⭐⭐ Small, Smart & Fast *by H***H on Reviewed in the United States 🇺🇸 on May 31, 2014* I've used a number of 12v chargers, but this is the best. I primarily use it to recharge a VMAX 35Ah AGM trolling motor and 8Ah AGM fish finder battery. I sometimes spend 10 hours or more on the water on a pontoon, so I needed the lightest batteries I could get away with, and maximizing their charge is essential. So far, this system has always got me back to the dock with power to spare.Four green and one red LED lights give info re discharge level at start of charge and real-time charge status (lights also flash if you reverse polarity). When done, it shifts to trickle charge, so battery is always at its peak. Also like that it is small and light compared to other chargers. Standard computer power cord (IEC) connector can be removed, and it easily stores tackle bag.Highly recommended. ### ⭐⭐⭐ A lick and a promise *by P***S on Reviewed in the United States 🇺🇸 on December 4, 2018* Plugged it in and it lit up like a Christmas tree. Not clear it was doing anything. Didn't seem to charge since battery was still in gasping mode later. Left connected all night. Battery was alive in morning. Assumed something wonderful happened since battery showed signs of invigoration--barely, but a good sign. I will keep it hooked up although running up my electric bill. Have a nagging feeling that I should buy a new battery. My return on this investment is questionable. But a lesson earned is a lesson gained. I'll keep it--maybe for electroconvulsive therapy. Perhaps I should enclose a pic with a clip on each of my ears. --- ## 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.pl/products/4179271-vmaxtanks-bc1204-12v-3-3-amp-4-stage-automatic-smart](https://www.desertcart.pl/products/4179271-vmaxtanks-bc1204-12v-3-3-amp-4-stage-automatic-smart) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-23*
