## Description

HTRC 3A Smart Car Battery Charger 6V 12V, Automatic Trickle Charger & Maintainer for Motorcycle, Boat, Lead-Acid(AGM/GEL/EFB) & LiFePO4 Lithium Batteries: desertcart.co.uk: Automotive

Review: Good output for small charger - Have used a few chargers over the years as I often have to charge numerous batteries in my workshop. This little cheap charger seems to do the job well. It has a decent output for the size. My last similarly sized charger output just 4amps which is slow when charging larger truck batteries with 180ah or more. I've used the charger on everything from motorcycle batteries to truck batteries and the various settings allow you to output accordingly to charge at the correct rate. Yes it's not the best charger out there but it is small, lightweight and cheap. The screen is clear and shows various information such as ambient temp, total amp hours, charging amps etc which is a nice feature.
Review: Charger small but effective - Bought this to charge a dead battery was easily connected and charged with no noise the lead was good altho obviously I had to use an extension leas anyway it was simple to use overall happy with it

## Features

- 🌟🌟【3A Smart Fast Charging & Automatic Maintenance】As a professional car battery charger 6V 12V, it delivers 3A high-power output for fast charging of car, motorcycle, boat, and lawn mower batteries. Fully charged, it auto-switches to trickle charger mode (trickle charger for car battery) to prevent overcharging and extend battery life—all-in-one charging and maintenance for daily convenience.
- 🔋🔋【Wide Compatibility for Multiple Batteries & Scenarios】Auto-identifies 6V/12V voltages, compatible with lead-acid (AGM/GEL/MF/EFB/SLA/VRLA/WET), lithium, and LiFePO4 batteries. This 6V 12V battery charger works perfectly as a motorcycle battery charger, car battery charger, or for boat/lawn mower batteries, meeting versatile home and outdoor needs.
- ⚡⚡【Pulse Repair to Revive Aged Lead-Acid Batteries】Built-in intelligent memory detects sulfation and acid stratification. The latest pulse repair technology restores battery activity and extends service life (only for lead-acid batteries). NOTE: Completely dead batteries cannot be activated—keep batteries moderately charged for better performance.
- 🛠️🛠️【Easy Operation & Versatile Connections】Short-press to select charging mode (no long pressing needed). Supports 12V forced charging for low-voltage batteries with clear steps. Equipped with 2 SAE connectors (motorcycle direct connection), ring terminals (long-term use), and fully wrapped clips, adapting to diverse scenarios.
- 🛡️🛡️【8 Safety Protections & 1-Year Warranty】Features 8 safety protections: over-voltage, over-temperature, short-circuit, over-charging, reverse connection, over-load, low-voltage, and over-discharge. Compact design with 275cm max cable reach for easy home & outdoor use. We offer a 1-year warranty—free replacement for any quality issues, ensuring worry-free purchase.
- ✅✅【12V Forced Charging Mode】If your 12V battery voltage is too low, the charger may misidentify it as 6V. Press and hold the button for 3s until 3 beeps, release, then hold again for 3s until 3 beeps — 12V Forced Charging Mode activates instantly.
