I have 4 x T105 trojan batteries in series giving me a 24 volt system
They are currently just sitting there in case of a power failure and then
the will generate 240 volts AC via my inverter.
I feed them from a 40 amp basic battery charger, you know just a transformer
and a rectifier.
I put them on charge once a week or so and charge them at around 29.5 volts
and once then have been on for say 12 hours the current drops down to under
one amp, at the moment .7 of an amp, leave them on longer and the current
drops futher. BTW outside temperature now (Night time here 5 AM) is 24 c or
75 f. In the day it will be around 30 c or 86 f.
I usually leave them on charge for about 24 hours at a time.
Now as I want the batteries to have the longest life possible, is there any
out there who have experienced keeping these batteries alive for a long
period, and do they have any advice.
No, I do not wish to spend a lot of money on an automatic charger. A 40 amp
automatic charger cost over $AUS 1500.00
So any advise on keeping these batteries healthy for a long time? They are
curently about a year old and never been cycled, as I do have other power
back up system.
Before charging they usually are around 25.2 volts, and they never go below
that as that is when I put them on charge.
