sealed Flooded Lead acid

[errolSA]

I tried to open up my other battery (DC31MF) but with no luck its top is like melted closed, and the top part has like cavities in so that each sell has a "water return" like a area where the water evaporation can condense and run back in to its cell.. So now I'm bit confused, are these maintenance free batteries any use for solar. But when I was reading this site it hit me, solar panels and charging batteries with solar is a complete wast of time.. Because a battery will never get to its full charge. When all my lights are on I use 4,3amps I never use all my lights at the same time. But it seems like my solar cant get my battery fully charged.. Battery volts can no drop to 12.5v(1a draw at night) when the controller turn off in the morning.. But then around 11 in the morning my battery is in float charge. Is my solar charging too fast at 10,9amps..

No these batteries are completely sealed (the once I have), I had one battery that failed so I tried to open it, there was no way but to cut it open.. When I got it open I found that one of the positive side the plates was a reddish rust colour, but I'm sure this battery was a normal starting battery an not a deep cycle maybe a type of Marine battery.. But lucky I got them for free so its no loss lol and I'm still in the learning stage..

There is no such thing as "sealed flooded lead acid batteries".
You may be thinking of "maintenance free" FLA batteries which have extra height of free electrolyte and cell caps which are very difficult to open but are NOT pressure seals.
The way they should be handled is just like any FLA battery except you have to pry the caps off to add electrolyte (which they will eventually need) or to use a hydrometer to measure specific gravity.

Hello everyone..
I have some questions to ask about Sealed Flooded Lead Acid batteries..
1.is there any change in the charging than the normal FLA batteries.?
2.are they also Valve regulated, if so what's the charging current they can take for lets say a 100ah battery..
3.if I change these sealed FLA batteries with the "max smoke" procedure won't it damage my battery plates and have excessive water loss that I cant replace..
