A healthy 12-volt battery should maintain a voltage range from 9.6 - 10.5+ volts under the load for 30 seconds straight. We don't expect you to run the starter for 30 seconds for starting batteries, so if you see the voltage meter drop within the voltage range and it sounded like a good strong start, then you probably just had a discharged battery.
Part of maintaining a reliable Uninterruptible Power Supply (UPS) system is making sure the battery is healthy, updated, free of errors and fully functional. While batteries do degrade and age over time, checking up on battery health is part of prolonging their life span and keeping your Uninterruptible Power Supply running at its best levels.
During a physical inspection, make it a point to look out for rust, corrosion and any signs of damage to both the battery itself and the surrounding equipment. You should also check the general area in and around the UPS, to make sure you keep it clean and free from any debris (dust, dirt, rust etc) that could interfere with proper operation.
Testing a lithium-ion battery is a sure way to tell if it’s bad. You can test these metrics if you don’t notice any visible signs but suspect the lithium-ion battery has reduced capacity, a high self-discharge rate, or constantly low voltage. It involves measuring the battery’s performance and comparing it with the manufacturer’s specifications.
Excessive heat generated by a battery is an obvious sign of something wrong. Compare the actual temperature with the normal operating temperature and take action immediately if the temperature is higher than normal because excessive heat can be dangerous and a fire risk. Like overheating, swelling is another visible sign that something is wrong.
Now push the start button and watch what the voltage drops to. It doesn't matter if the bike starts or not, what you're looking for is a voltage reading. A healthy 12-volt battery should maintain a voltage range from 9.6 - 10.5+ volts under the load for 30 seconds straight.
