Equalization on 525FLA batteries

Post by ramiryx » Thu Aug 17, 2017 12:29 pm

I bought 4 batteries 525FLA and connected in series for a 24V battery system.

In the battery datasheet it show the equalization voltage, but do not mention about the duration and/or the frequency of this procedure.

Please help

okay.will help you. Batteries designed for residential or light-commercial off-grid renewable energy power demands.It has a heavy-duty internal connectors and terminal post structures enable unmatched electrical efficiency and durability.Equalizing lead acid batteries is a process designed to de-sulphate the battery plates by carrying out a controlled overcharge.For more refer on web please.

Please help
Not sure about the duration for your model batteries however regarding the frequency, equalisation "charges" need to be done when the SGs (specific gravity readings) of your individual battery cells start to diverge from each other ( generally some lower than normal), this can generally be as a result of incomplete charging cycles and/or too short an absorb charge period.
So, check your SGs regularly and take note of each cells readings in a written log, when things start changing ie SGs of one or more cells remain low then you can look to do an equalisation charge.

Here's an excerpt from the Rolls battery manual describing the EQ process:

The duration will depend on how long it takes for all your batteries' electrolyte to reach 1.265g/cc specific gravity.
