Hey there!
Maybe someone has some ideas....
i just bought a 25Ah car battery (was alot cheaper than a maintenance free SLA), and i needed a high capacity to run a 150w inverter for a couple a hours every second day or so, (if you a south african, you'll know why---LOADSHEDDING!)
This will be to run my filter system in my aquarium while the government tries to figure out a solution to this big mess!
Anyway, the specs i got from the bat supplier are as follows:
*Terminal voltage at full charge: 13.8V
*Check water (not maintenance free)
*it is a deep discharge battery (hybrid- whatever that means)
*should be charged at 15Amps! (with intelligent charger that costs more than 10 times the price of the battery!), which blasts the plates with 15A, and then somewhere along the process, drops down to finish off the charge.
Now i'm worried about the 15A part, and have no intention of getting a transformer the size of the battery!
I can get a swithcmode laptop charger as a power supply instead, and then build a regulator to maintain the 13.8V or so.
Can this battery be charged the same way as a SLA, with constant voltage, continuously (so its always charged, and ready to go).
can i set charge current at 0.1C (2.5Amps) and get a full charge?
Help me soon someone,
My poor fishies
