Replacement deep cycle batteries

[Mistroma]

Trojan do a 130AH deep cycle lead acid thats the same physical size as a normal 110AH. That works for me as the battery box is made for the 110AH size, so two of them give me an extra 40 odd AH's .

I considered the 12V Trojan batteries about 5 years ago but rapidly went off the idea when I checked price and performance. Trojan's own technical people confirmed that they only expected the 12V ones to have half the life of the 6V variety. They emailed some graphs and confirmed I wasn't misreading them.

Last time I checked I could get 4xT105s (450Ah@12V) for £520 (Batterymegastore) or £550 (Tayna).
I think the 12V 130Ah versions were about £570-£600 from Tayna.

The T105 battery is not only cheaper, it should last twice as long. It's worth pointing this out in case someone is tempted to buy a 12V Trojan on basis that they must be as good as the 6V T105s.

Of course size is the big problem. The benefits were so great that I re-built the battery box to take the T105s. Others may well decide that it wouldn't be worth the effort.

Another benefit to T-105s or other GC2 size batteries, they only weigh about 20 Kgs. In my younger days I used 4D size 12V (supposedly) deep cycle batteries. Not sure if I could lift one over the rail any longer.

T105 weighs 28kg

I thought that my T015s each weighed about 28kgs, not 20kgs. They aren't exactly lightweights.

I remember a friend asking if he'd be better off buying 2 x 230Ah batteries instead of 4 x 115Ah. I knew that his battery box wasn't the easiest to reach and told him to try lifting a 230Ah battery. Needless to say he went for 115Ah and understood why they were more popular than the larger size. The extra redundancy was a bonus as less of an issue if one battery fails.

My 3 Lifeline AGM house batteries are 8 years old but seem to still be working perfectly ..... which is a very good thing because they weigh more than 60kg each and are going to cost me around £700 each to replace. I've no idea how I'm going to manouvre the old ones out or get the new ones in when the time arrives. :ambivalence:

Don't you know that in American English, using alternate facts, "about 20 Kg" means 28 Kg in UK speak?

Agree, 28 Kgs (or 20 Kgs for that matter) is not exactly light weight. On the other hand a 4D, depending on brand and model weighs in at 48-55 Kgs. Think I'll stick with the 28 Kg version.
