Models RG Tianye differ in power (from 4 to 20 A) and supported battery types. For example, RG Tianye T-1000 suitable for batteries with a capacity of up to 100 Ah, and RG Tianye T-2000 - up to 200 Ah. Please check compatibility with your battery before purchasing!
Preparing the battery for charging: step-by-step instructions
Before connecting RG Tianye, the battery must be properly prepared. This will minimize risks and improve charging efficiency.
⚠️ Attention: Never charge a frozen battery! If the battery has been in the cold, let it warm up to room temperature (at least 2–3 hours). Charging a cold battery may cause explosion or damage to the plates.
Preparation steps:
- Cleaning the terminals. Remove oxides from the battery contacts with sandpaper or a special brush. Oxides increase resistance and interfere with normal charging.
- Checking the electrolyte level. In serviced batteries, unscrew the caps and add distilled water if the level is below normal (the plates must be completely covered).
- Condition assessment. If the battery is swollen, cracked, or leaking, it cannot be charged and must be replaced.
- Choosing a location. Charge the battery in well ventilated area (garage, balcony). During the charging process, hydrogen is released, which is explosive in high concentrations.
☑️ Preparing to charge RG Tianye
If the battery is completely discharged (voltage below 10.5 V), some models RG Tianye may not recognize it. In this case, use the mode REPAIR or BOOST (if any).
Connecting the RG Tianye Charger: Step by Step Guide
Incorrect connection is one of the main reasons for failure of both the battery and the charger. Follow these instructions to avoid errors:
- Turn off the charger. Connect the terminals only when disconnected from the mains RG Tianye.
- Connect the clamps to the battery:
- 🔴 Red clip (“+”) - on positive terminal battery
- ⚫ Black clip (“–”) — on negative terminal.
⚠️ Attention: If the polarity is reversed, the protection will work, but repeated errors can damage the device.

The display will show the current battery voltage and charging current. In the first minutes the current can be high (up to 10 A), but then the device will automatically reduce it to a safe level.
If the charger does not turn on, check the fuse in the power cable (if applicable) or try a different outlet. Some models RG Tianye sensitive to power surges in the network.
RG Tianye operating modes: which one to choose for your battery?
Devices RG Tianye support several charging modes, each of which is designed for specific tasks. Selecting the wrong mode may result in incomplete charging or damage to the battery.
| Mode | Description | When to use |
|---|---|---|
AUTO |
Automatic current and voltage selection | For most lead acid batteries (recommended for beginners) |
MANUAL |
Manual current setting (e.g. 2 A, 5 A) |
For experienced users or specific batteries (for example, tractor batteries) |
REPAIR |
Pulse mode for the recovery of sulfated batteries | If the battery has not been used for a long time or does not hold a charge well |
BOOST |
Accelerated charging with increased current | Only for emergency cases (no more than once a month!) |
MAINTAIN |
Maintenance charging (compensates for self-discharge) | For long-term battery storage (for example, for the winter) |
For gel (GEL) and AGM batteries necessarily choose the appropriate mode! Charging mode WET will lead to overheating and battery failure.
What is desulfation mode (REPAIR)?
Desulfation is the process of removing lead sulfate from the battery plates, which is formed during deep discharges or prolonged inactivity. In mode REPAIR RG Tianye supplies current pulses of different frequencies to the battery, which helps restore up to 70–80% of lost capacity. However, this process can take up to 24 hours and is not recommended to be interrupted.
Common mistakes when using RG Tianye and how to avoid them
Even with an automatic charger, users often make mistakes that shorten the battery life or damage the device itself. Here are the most common of them:
- ⚡ Ignoring polarity. Connecting “+” to “–” and vice versa can burn the diode bridge in the charger. Always check the terminal markings!
- 🌡️ Charging in extreme temperatures. Optimal charging range:
+10°C…+25°C. In cold weather, the battery capacity drops, and in hot weather, the electrolyte can boil. - ⏳ Interrupting the process. If you turn off the device before the cycle is complete (especially in
REPAIR), the effect will be minimal. - 🔌 Using extension cords. Long or thin wires create a voltage drop, causing RG Tianye may not correctly detect battery status.
Critical error: connecting the charger to a battery that is not disconnected from the vehicle's on-board network. This can damage electronic control units (ECUs) due to power surges. Always remove the terminals from the battery before charging!
If the charger shows an error ERR or FAIL, immediately disconnect it from the network and check the polarity, condition of the terminals and battery voltage (must be at least 2 V).
Charger Maintenance and Storage
To RG Tianye served for a long time, follow simple care rules:
- 🧹 Clean the housing. Dust and dirt may get inside the device and cause a short circuit. Use a dry cloth or vacuum cleaner.
- 🔌 Store in a dry place. Humidity causes contact corrosion. Optimal storage temperature -
+5°C…+30°C. - ⚡ Check cables. Over time, the insulation can crack, exposing the wires. Replace damaged cables to avoid electric shock.
- 🔋 Discharge the device before long-term storage. If you don't plan to use RG Tianye more than a month, disconnect it from the network and discharge the built-in capacitor (just hold the power button for 10 seconds).
If the device stops turning on or shows incorrect values, the reason may be:
- Blown fuse (replace with one of similar rating).
- Damaged network cable (check with a multimeter).
- Oxidized terminal contacts (clean with sandpaper).
Warranty for RG Tianye Typically 1-2 years, but does not cover damage caused by misuse (such as shorted terminals).
Frequently asked questions (FAQ)
Is it possible to charge the battery without removing it from the car?
Technically possible, but highly not recommended. During charging, the terminal voltage may exceed 14.4 V, which is dangerous for the car’s electronics (especially modern models with sensitive control units). If you still have to charge on site, disconnect the negative terminal!
How long does it take to fully charge a battery?
The time depends on the battery capacity and charging current. For example, for a battery 60 Ah at current 6 A it will take about 10 hours. In mode AUTO RG Tianye automatically reduces current as it charges, so the process can take up to 12–15 hours. Gel batteries take longer to charge – up to 20 hours.
Why does my charger show "ERROR"?
Error ERROR or FAIL may mean:
- Incorrect connection polarity.
- Short circuit in the battery (check the voltage with a multimeter).
- Battery voltage is too low (less than
2 V- “resuscitation” with a specialized device is required). - Overheating RG Tianye (let it cool for 30 minutes).
Disconnect the device, check all connections and try again.
Can RG Tianye be used to charge lithium batteries?
No! RG Tianye Suitable for lead acid batteries only (WET, AGM, GEL). Lithium batteries require special chargers with voltage and current control. Trying to charge a Li-ion battery RG Tianye will lead to his fire or explosion!
How often should the battery be charged for maintenance?
If the car is used regularly, it is enough to maintain the charge using the on-board network. But if the car sits idle for more than 2 weeks (for example, in winter), connect RG Tianye in mode MAINTAIN once a month. This will prevent sulfation and extend the battery life by 2-3 years.
