YES, QUITE LIKELY
Different battery types and brands require different charging regimes to effectively charge.
Here are a few examples of the charging specifications for different batteries:
|Battery Brand, Type||Bulk Charge Voltage ||Float Charge Voltage||Equalise Voltage |
|ULTIMATE, AGM||14.4V||13.4V||DONT equalise|
|REMCO, AGM||14.7V||13.7V||DONT equalise|
|HOPPECKE, AGM/GEL||14.4V||13.5V||DONT equalise|
Whereas here are the battery charging setpoint options from the Prostar Morningstar solar regulator:
|Battery Setpoints for:||Bulk charge ||Float Charge ||Equalise Charge |
|Flooded Battery||14.4V||13.7V||14.9V / 15.1V|
|Sealed or AGM Battery||14.15V||13.7V||14.35V (1hr only)|
Different solar regulators can have very different settings so you need to be familiar with what settings are available in yours.
You have to chose one of them and it wont necessarily be the one you'd expect. For instance, with the Prostar solar regulator the FLOODED battery setting is the most appropriate setting for some AGM Batteries because the AGM setting has a bulk voltage which is just too low to properly charge it. The flooded setting has an equalisation stage but 14.9V is an acceptable voltage for some AGM battery brands.
Programmable Solar regulators are a good option
Its also worth noting that most equalisation voltages just aren't high enough to offer a really effective equalisation charge for a flooded battery. With flooded batteries (and a number of other batteries) we generally prefer to go for a solar regulator which is programmable or which has many more battery setting options to choose from, for instance, the Trimetric SC2030 or the Tristar Morningstar units which are fully programmable or some of the Xantrex C12 & C35 units which have around 10 battery setpoint options.
Mains Charger settings are even more important
The above just covers the solar regulator charge settings. Your mains charger will also have specific settings which you need to select from. The mains charger settings are even more important because the battery will be exposed to these voltages for longer periods of time. Solar is generally at a lower level (10-15Amps for most systems) and solar turns on and off as weather conditions vary. And because night interrupts charging, at most the solar will be charging for 10 hours per day (often less).
Mains chargers are generally 25+Amps and can be run for 24 hours per day, for days on end - the battery wont get a rest from the voltage so you need to ensure the setting is correct.
Know what charging voltages your battery requires and what your charger setpoints are
If you change your batteries and don't check/change the charge settings on your various charging sources you could risk damaging your new battery bank by overcharging it or weaken it by undercharging it.
Before replacing your batteries you should check that you have appropriate settings on your solar regulator and mains charger for the new batteries so you'll need to see a specification sheet including the recommended charging voltages of those batteries.
LEAVE IT TO THE EXPERTS and we'll do it all for you
Whenever we replace a battery bank we always ensure the batteries are suitable for the existing charging sources and that those charging sources are on the correct setting for the battery bank.
