I'd be interested to hear people's thoughts and experiences good bad or indifferent if they have fitted an Optima battery either the 12 or 6 volt  types. 

Iv'e read up a bit on them :readbook: and they sound very good but the proof is in the pudding as the saying goes or in this particular case the cold and hot starting, lack of off gassing and long term storage potential....... so what do people think are they the answer to CCA and that depressing hot start wheeze or just a funny looking dude stuck in the battery tray ??

I have an Optima battery on my old diesel Opel Kadett, it was fitted by previous owner, so no idea of its age,  I've owned the car for over 7 years,  so battery must be at least 10 years old,  the car lives outside, often left for weeks and the Optima still keeps its charge,  even in frosty winter conditions it always starts the diesel, ..also had an Optima on a Bedford TK 330 Diesel,  surprising for a small battery the Optima  always started it

Had one in the Jeep for last 7 years no regrets buying one, holds its charge great, no need for tickle charging, and turns her over really fast. Dave

There is also the Odyessey range. I have one those and abused it for several years, still goes.

Used one in a 109 Land Rover with a later 2.5 n/a fitted, always started even after being left for ages, also two in the wife Tdi powered 109 camper conversion one red top and a yellow top leisure battery, no dramas with any of them. I did put a pair in my early 24v 40 amp SWB FFR though and for some reason it didn't like them and one of them won't charge properly so gone back to lead acid in that one  but the 12v 109's are great with theirs.

A surprisingly small number replied to this thread,  whether this reflects a limited take up for these batteries or general apathy/state of the WP toilets diverting forum attention is not possible to define :) ,   putting that aside the general consensus from those who did reply is very positive so thanks for your input gentleman.

I found this on one review of Optima batteries:-

Overcharging or charging improperly can damage the battery.

Hi Pete , only just seen your post as I'm afraid I do not bother to visit the forum very often these days . I have had a couple of Optima batteries over a period of years . I put one on my WC54 after I got fed up with the standard having insufficient guts to get it started . I  now have a pair on my jeep after the originals died during the period of all my electrical problems , they have been there for a couple of years doing sterling service . I also had one of the larger ones which ended up in the Snow Trac when I sold that . They have all been good . If they stand around for ages they will loose charge eventually . I actually have a dead one in the garage which I bought to fit in my Triumph Vitesse . Due to various plans coming unstuck I've not got that back on the road again as I had promised myself I would . That battery has sat unused for quite some time , it's been abused for various jobs and left without being recharged , I've not looked after it properly and , unsurprisingly , it has expired but that's through my neglect rather than anything else . Yes they are a bit more expensive but I've come to believe that they are worth it .

You may be able to getthe dead one back by parralele charging. Stick a battery on charge then use jump leads to connect that to the dead one and charge both for half hour or so,. Gets enough charge back in the dead one to allow charging.

Brilliant for 6V.

We fitted one to a customer's F1 Ford with a flathead V8. It was the last throw of the dice before we converted it to 12V but it transformed things.  On one occasion I even wound it onto the trailer using the starter motor alone.

On the downside they don't look right in certain circumstances (EG a Jeep)

Thanks for the tip Tony , will give it a go when I'm back on my feet .

Regarding the look of the batteries , I know there ain't a lot of room to do it on a Jeep but on my Dodge I made up a ply box which fitted around the Optima to make it look , at a glance , like a rubber cased original . And it also helped to hold it in place it being so much smaller than an ordinary battery .

As a result of comments here, thank you all and other reports I have read elsewhere I have splashed out on  a 6 volt 50AH 800 amp CCA Red top Optima RTS 2.1 .

First impressions are very favorable staring from cold is much faster and starting from hot (around 200F after standing) is almost instantaneous which was not the case before.  I'll test run it for a few months and report back here on this thread on the overall performance.

It is however a funny looking dude sat in the battery tray so I'm going to have a go at fitting it inside a redundant Lincoln battery case that I have under the bench.  Others have done a similar thing with other cases so it should be possible.

There are several places in the US that sell dummy cases for classic cars just for this purpose but the shipping cost to the UK is prohibitive.  There is also a project ongoing again in the US to manufacture a reproduction Willard battery case ( factory fitted to Ford GPW and Willys MB) that will take the Optima this is still in the design phase at the moment however but could be worth keeping an eye on progress.

Pete
