BU-403: Charging Lead Acid
The lead acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge currents and multi-stage

Battery Discharge Cut-off Control
This circuit prevents over-discharge of a lead-acid battery by opening a relay contact when the voltage drops to a predetermined voltage (lower voltage threshold). When the battery is recharged to a second predetermined higher voltage (upper voltage threshold), the relay contact automatically re-closes and power again flows to the load.

What is a shorted lead acid battery?
CALCULATED VS. ACTUAL SHORT CIRCUIT CURRENTS FOR VRLA BATTERIES “shorted” lead acid battery has the capability of delivering an extremely high current, 100 to 1000 times the typical discharge current used in most applications. Electrical systems using batteries must be properly protected to avoid potentially dangerous fault conditions.
Do lead-acid batteries need to be adjusted?
Many of the float charge and discharge voltages of lead-acid batteries in UPS power systems have been adjusted to their rated values at the factory, and the discharge current increases with the increase of the load. The load should be adjusted reasonably during use, such as control of the number of computers and other electronic equipment.
How to install a lead-acid battery?
When installing a lead-acid battery, insulation measures shall be taken for the tools which are being used. When connecting, connect the electrical appliances other than the battery first, ensure there is no short circuit, and finally connect the battery.
How does a lead-acid battery shed?
The shedding process occurs naturally as lead-acid batteries age. The lead dioxide material in the positive plates slowly disintegrates and flakes off. This material falls to the bottom of the battery case and begins to accumulate.
How does corrosion affect a lead-acid battery?
Corrosion is one of the most frequent problems that affect lead-acid batteries, particularly around the terminals and connections. Left untreated, corrosion can lead to poor conductivity, increased resistance, and ultimately, battery failure.
