How to use

Install the VIPOW BAT0271 in equipment designed for 4V nominal battery modules, ensuring correct polarity and secure connections. Charge the battery using a compatible lead‑acid battery charger or charging circuit that matches the VRLA charging profile and recommended voltage limits for 4V cells. For standby applications, keep the battery on a float or standby charge per the equipment manufacturer’s guidance. For cyclic use, follow appropriate charge/discharge rates and avoid deep discharge beyond recommended depths to maximize service life.

Usage recommendations

Store and operate the battery within manufacturer‑recommended temperature ranges and avoid prolonged exposure to high temperatures. Regularly inspect terminals for secure connections and clean them if corrosion appears. Replace the battery when capacity falls below the level required for reliable operation in your system. Do not attempt to open or service the sealed battery; follow local regulations for proper disposal or recycling of lead‑acid batteries.
