4. Operation of sealed lead acid batteries

4.1 Preparation prior to operation
Batteries should always be fully charged prior to use, especially when use it
for the first time right after purchasing or after long period storage. Batteries
after long period storage will lose some capacity due to self-discharge, and
need recharge to restore its full performance.
Do not put sealed lead acid batteries in airtight containers, or install the
batteries in a room without ventilation. Gas generated by over charging
reactions in the battery may explode if ignited by sparks from machinery or
switches.
Tightly screw the connector with the terminal of the batteries.
Do not lay a metallic object on top of a battery.
Insert insulation that is acid and heat resistant between the batteries and any
metallic housing.
Do not charge the battery with upside down position, it may cause acid
leakage.
Batteries must be stored or used in the temperature range of:
Charging:
Discharging: -15°C ~ +50°C
Temperatures above or below these ranges could result in damage or deformity
of the battery.
4.2
Charging methods for standby use batteries
The purpose of charging standby use batteries is to compensate
self-discharge. The constant voltage charging method is commonly applied.
Standby batteries are continuously overcharged at a voltage only slightly
above their open circuit voltage, called float voltage. The low float voltage
