2. Acid Storage Battery
The remote control grab uses a 38Ah lithium battery box with a voltage of 12V.
a. First Use
The battery is shipped fully charged and can be used directly by the customer. If the battery has been stored for a long period (more than one month), it should be recharged before use. To recharge: connect the charger to the battery box, then plug it into a 220V AC power source. After the charger indicator turns green, continue charging for an additional 3–4 hours. The battery is then ready for use.
b. Preventing Over-Discharge
Once the battery power is depleted, the power must be switched off. Forcing the remote control grab to operate using residual voltage will cause over-discharge, which shortens battery life.
c. Battery Charging
Failure to charge the battery promptly, undercharging, or overcharging can all damage the battery's lifespan. Therefore, do not store the battery for long periods in a discharged state. Always recharge promptly after discharge; the deeper the discharge, the more urgent the need for recharging. If the battery will not be used for more than one week, charge it beforehand. If it remains unused for over two months, it must be fully charged. Do not use the battery when it is insufficiently charged.
d. Charging Procedure
To charge, connect the battery to the charger and turn on the power source (ensure the input voltage matches the rating on the nameplate; otherwise, do not operate). The charger automatically detects the battery's current charge level and ambient temperature, adjusting the charging process accordingly. Once the battery is fully charged, the charging system automatically shuts off. The charger will not output current in case of reverse polarity connection, output short circuit, or open circuit, preventing damage due to operator error. No supervision is required during charging.
Note: After each use of the remote control grab, every battery pack must be charged. When not in use for extended periods, store the batteries in a dry, cool place. Battery charge gradually depletes during use or storage, eventually leading to full discharge, which significantly reduces battery life. To prevent this, a protection circuit is built in: when the battery voltage drops below a certain threshold, the power protection device cuts off the circuit, stopping power output. If the remote control grab suddenly stops working during operation, it may indicate a low battery and require recharging.
The grab experiences heavy impacts and vibrations during operation, which demand robust electrical connections-especially for the battery pack, which is frequently removed and reinstalled. Therefore, waterproof, flexible sealed connectors are used for all contact points, ensuring safety, reliability, and convenience.
