tudor batteries

[cloud7]

we have tudor TG 1102 110ah batteries fitted , the battery connections cross over the top making it impossible to check if the tops come off for distilled water , anyone got these batteries? , is it possible they are a sealed unit? , yacht is a jeanneau and they came fitted from new, appreciate any views thks

I had then on my Jeanneau. It is a PITA but if you loosen the terminals, the two covers can be prised off to check the electrolyte. Hope this helps...

My batteries are under a steel deck, so I have to disconnect them to check the water levels. A PIA, but can't do much about it. I rationalise it by telling myself that at least the terminals are checked and re-greased regularly.

Can you re-route the cables to make them easier to get at?

i don't have enough play to re- route them , so its a standard jeanneau set up , which made me think they maybe maintenance free , but i can't find any manuals details on tudor 1102 professional 110 ah batteries. anyone know if they are maintenance few ? thks

It appears they are not sealed from their website.

thanks for posting could you give me the link to the site , i have not been able to find it..

Tudor is a brand under Exide. Your battery seems to be a standard truck battery based on antimony/calcium technology, so likely no need to top up very often. But probably possible to do.

I googled tudor 1102, got the exide site, checked there.

......and sorry also seem to be the cheapest of the range, only 90 cycles, which is of little use as a domestic battery. OK for engine start.

Tudor are the Exide cheap range. Whilst the 90 cycles is excessively pessimistic, they do have a shorter life than some other ranges, but if they are never allowed to drop below 12v resting should give more like 250 cycles.
The plate hardening material is almost certainly antimony, not calcium, as that material allows the manufacturer to produce thinner plates (cheaper, greater area for high CCA) and in common with all other flooded lead-acid batteries they need their electrolyte level checked regularly.

It is quite clear from the leaflet linked to that the TG range, aka "Professional", is based on antimony/calcium technology, probably meaning antimony in the positive plates and calcium in the negatives.
Calcium is used to reduce gassing and eletrolyte loss, so the need to top up frequently should be reduced compared to traditional antimony technology.
I agree the TG is a basic kind of battery and poorly suited for marine use, e g less spill proof than the more up market ranges. There is however also a TH range ("Economy").
BTW it is a bit misleading to claim Tudor is "cheap range". Might be so in the UK market, but as the leaflet shows various Exide ranges are sold under the Tudor brand.

I had the same batteries on my 2009 Jeanneau 42DS. I'm usually pretty good with flooded batteries and ones on previous boat lasted between 8-11 years. However, power usage on 42DS is much higher so I was only expecting 5 years.

I checked remaining capacity after 3 full seasons and found 65%, 79%, 60% of 110Ah. Batteries held this charge well but capacity was too low for my planned extended cruise.

I'd agree that these are more like lorry start batteries and not fit for deep cycling.

I fitted 4x Trojan T-105s and am happy with these (450Ah & ~£125 each). I'm hopeful that they will last a reasonable time. Lorry batteries weren't much cheaper so nothing much to lose.

Only problem was that battery box was 2mm too narrow and not deep enough (2mm again). I re-built the box to give another 25mm width and 50mm depth (allowed me to fit forced ventilation).
