I am looking for reasonably priced leisure batteries to play around with a solar system and see what serves my needs best.
I have spotted Probat leisure batteries rated at 110ah
on ebay under £60. Anyone had any experience of this manufacturer and are they ok for the money. Obviously if I spend more I will get a better quality battery but are the Probat batteries a reasonable option?
Personally I would be looking at lithium ion cell battery rather than LA, as LA will be pretty much done in after 5 years, whereas Lithium ion should be good for 10 years or more.
Also the weight fact, LA is heavy, albeit cheap.
Quite a few firms now offering Lithium ion 12v batteries as replacement for LA leisure and car batteries.
I still find it funny that Tesla cars come with a bog standard LA 12v battery, yet the car has a lithium battery pack that is stuffed with some 4,500 lithium ion cells.
Although many owners change the 12v LA for the lithium ion equivalent, when it’s time to replace the LA battery.
Given that a 100Ah lithium ion batteries seem to start at about £700. I think I would be looking for a lead acid battery. Albeit from a named brand. For the record I am currently using Varta 90Ah LFB battery, o think it cost £105 from Tayna iirc.
For what it’s worth, in terms of quality for a given Ah rating it is the heaviest LA that is the one to go for.
I bought this very battery a few weeks ago but have yet to use it because the posts are a smaller diameter than the original battery posts so don't fit the quick release terminals. I'm now looking for some kind of adapters
Yes, while lithium ion are probably the way forward, I can't justify the cost at the moment.
My plan is to use two Probats at 110ah as a battery bank in the caravan, trickle charging off 2 x 50w solar panels. I plan to leave the current leisure battery, which is a Tayna at 110ah in the caravan as is and swap them around when needed. The ideal would be to get an inverter on the system as well but I may have to lose a bit of wardrobe space for that to happen. ( don't tell the wifey :-)
For the price of a couple of lithium batteries you could buy a EFB battery and a VeGA fuel cell
Personally I'd just buy a EFB battery from halfords etc, I have a standard wet battery for my solar system, but my next battery will be a EFB leisure battery.
Got an mppt charge controller on the panels and that has two usb outs for mobile phone chargers etc. and works a treat.
Also got 4 second hand car batteries on rotation varying from 65ah to 90ah and the panels will charge them up in 2 to 3 hours with no load on them and full sunlight.Using those batteries for all sorts including topping the pond up from the stream with a 12v pump and powering the strip of 12v led lights in the workshop. The strips that you see all over the back of cabs in lorries are just the thing for illuminating over workbenches in the garage/workshop and relatively cheap especially compared to 500w halogen spots!!!.

Inverters are not that efficient. Often people use them to convert DC to AC and back to DC which is even worse.
A DC-DC converter will be a better option.
Very true. The only AC 240v item we need to run is a laptop but it isn't really 240v it's 19v DC. We got a 12v to 16-24v convertor to fit.
