12v trojan battery
Just after a bit of advice please , Im thinking about getting a 12v 105 amp trojan battery as my leisure battery is on it's last legs , can this be connected to the split charge relay or is it better to charge it every so often with my intelligent charger ? Apologies if this question has been asked before I do remember reading about this but can't seem to find the post
Thanks jeff

Either way is OK, but the intelligent charger will likely do a better job of charging it quicker.

intelligent charger every time
trojans are built differently to leisure batteries, it might do you well if you e-mailed trojan and asked.

I had a thought about this during a conversation at the recent Pikey meet (and it crosses into "Sterling Charger" territory too)
If one already has a reasonably heavy duty inverter (as many of us do) and connected it to the main battery, then arranged a nice heavy "cross over" switch (or relay) to isolate the leisure battery, then, when the engine is running, one side of that "switch" could connect to an intelligent charger (say 10 or more amps) and that would do a much better job of charging the leisure battery than the alternator ?

(I wonder if this should this be on a fresh topic )

Re: 12v trojan battery
Its not going to be used for anything heavy duty , the propex heater , stereo and occasionally a 12v TV, I was curious how long a 105 amp Trojan would last if it wasn't being charged through the split charge

Interesting idea - adding a good charger like that would definitely be cheaper than just using one of those breathtakingly expensive alternator-to-battery chargers. But would the benefit of the charger make up for the losses through the inverter? I have no idea what sort of numbers we'd be talking about.

100ah worth?
For me, in winter, thats three days with the eber on all the time. Four days if its just for the heater. Most of the time i dont have the heater on 100% of the time, but sometimes i do. It's a very hard question to answer.
I personally need a split charger - it depends how you use your van whether or not you need one.
Good luck,

Re: 12v trojan battery
trojan energy release is somewhat different to a standard "leisure" battery
personally I'd just charge it at home and see how long it lasts without any intelligence

We never did agree on this did we Kev
Physics proves that 105ah is 105ah.
That means you can theoretically draw an amp for 105 hours.
A Trojan battery just means your closer to the theoretical max. Unless they defy physics....

I agree, but the issue with batteries seems to be labeling. How come Powerline can make a battery that they claim to be 100ah, when the likes of Bosch, even with a slightly larger battery only claim 77ah?
After load testing 2 of the Powerline 100ah batteries recently it would seem they are no where near what they claim.

Re: 12v trojan battery
Nope it depends on the standard rating that is used, 20 hour, 8 hour rate etc. A 100 ah battery rated at 8 hour has a larger capacity than a 100 ah battery rated at 20 hour.ringo wrote:
