[quote="threedee";p="3165426"Constant voltage charge (25c) Cycle use 7.2-7.5v Standby use 6.8-6.9v[/quote] Like it says, you need to apply a constant voltage of 7.2 to 7.5 volts (or the lower voltage range for "trickle" standby charging). It might be sensible to start with a lowish voltage e.g. 7v if the battery has been discharged for a long time.
Lead acid batteries give off fumes when they''re being charged, so it''s important to have good airflow. You also want to avoid any open flames or sparks near the battery while it''s charging.. Sealed lead acid batteries are designed to be maintenance-free, meaning that you don''t have to add water to them as you do with traditional lead acid batteries.
Lead acid batteries need to be charged in various stages and voltages. This can be difficult to do, so the best way to charge your battery is to use a smart charger that automates the multi-stage process. These smart chargers have microprocessors that monitor the battery and adjust the current and voltage as required for an optimal charge.
Charging a lead acid battery can seem like a complex process. It is a multi-stage process that requires making changes to the current and voltage. If you use a smart lead acid battery charger, however, the charging process is quite simple, as the smart charger uses a microprocessor that automates the entire process.
Chemical energy is converted into electrical energy which is delivered to load. The lead-acid battery can be recharged when it is fully discharged. For recharging, positive terminal of DC source is connected to positive terminal of the battery (anode) and negative terminal of DC source is connected to the negative terminal (cathode) of the battery.
A Sealed Lead Acid battery is a secondary cell battery that can be re-charged. It is charged by sending electrons through the battery to reverse the chemical reaction that creates the energy output. The electrons in an SLA battery are stored in the positive plate, which is made of lead dioxide (PbO2).
Charge your battery at least every 6 months when it's in storage. When stored at 20 °C (68 °F), your lead acid battery will lose about 3 percent of its capacity per month. If you store your battery for a long period without charging it, especially at temperatures higher than 20 °C (68 °F), it may experience a permanent loss of capacity.
Strings of lead acid batteries, up to 48 volts and higher, may be charged in series safely and efficiently. However, as the number of batteries in series increases, so does the possibility of slight differences in capacity.
