4G Real-time Temperature Recorder for Water Baths in Lead-Acid Battery Formation
In lead-acid battery manufacturing, formation is a critical process that directly determines the electrochemical performance and cycle life of the finished batteries. During formation, batteries generate intense heat and must be kept within a strict optimal temperature range to ensure high quality. To achieve this, water baths serve as the core equipment for temperature control in the formation process. The water baths operate under weak acidic conditions (0.1%–0.5% concentration) across a temperature range from 10°C to 70°C. It removes the heat generated by batteries through continuously circulating cooling water. COEUS-4G is introduced as a 4G real-time temperature recorder for water baths in lead-acid battery formation, to ensure precise temperature monitoring of water baths and successful battery formation.

Designed for demanding industrial applications, COEUS-4G real-time temperature recorder is ideally suited for water baths monitoring in battery formation:

Multi-channel monitoring: Equipped with two optional external probes covering a range of -30°C to 70°C, this 4G recorder fully meets the 10°C–70°C requirement of the water baths. The main unit can be easily installed in the plant to monitor indoor ambient temperature, featuring s a backlit LCD screen for clear readability even in low-light conditions.
4G Network Transmission: The built-in 4G network eliminates complex wiring and adapts to any plant layout. With configurable logging intervals (1min to 24h), all temperature data from the entire formation cycle is automatically uploaded to cloud and accessible via both Mobile APP (iOS/Android) and Cloud Platform (PC Web).
Multi-channel Alarms: If temperature runs out of range, the system will immediately trigger both local audible and visual alarm and remote SMS, email and APP push alerts, helping prevent thermal runaway accidents, guarantee battery formation quality and meet process traceability requirements.
Professional Reporting: All data uploaded is automatically analyzed. To quickly get the data you need, filter the daily, weekly or monthly data, or export PDF/CSV reports of each independent sensor with periodic extreme values (hourly, daily, weekly, monthly).
Dual Power Supply: Type-C wired power plus a built-in rechargeable battery ensures continuous operation even during unexpected plant power outages or circuit failures.
From real-time data traceability to alerts, Freshliance’s COEUS-4G real-time temperature recorder delivers a highly reliable, easy-to-deploy temperature monitoring solution for lead-acid battery formation water baths. It helps manufacturers strengthen quality control and gain a competitive edge in a demanding market.
