light weight engine battery

My bank ....

Is a Heavy Duty Diesel Starter of 100 A/Hr as my main start battery ...... B on the switch.

Second used mainly for Domestic use is a 120 A/Hr truck battery ......

Both are 'crankers' ...... I do not advocate using small car battery's - but I can honestly say that I have used them on my Alacrity and Snapdragon 23 years before - due to lack of space. I tried Leisure battery's and they were ok ..... but I didn't get any more length of life out of them than the others .... cost me about a tenner more though !!

My Domestic is charged regularly from the engine while motoring out - once the starter battery has had a good dose put back and I try to plug in when I get on pontoons. While the boat is laying alongside her normal berth - there is a trickle charge solar-panel bought in a car shop that keeps the domestic battery topped up. Yes I do occasionally use the 120 A/hr job to start the engine .... believing that the load may be good for it, but then I think its wrong !! But hasn't done it any harm.

The set has survived for near 5 years now and I therefore feel I can claim that I have had my money's worth.

Cost of each battery : 100 A/hr Diesel HD - 45 quid from local Tyre / Battery Centre ..... 120 A/Hr Truck - 60 quid from specialist Truck centre .......

Oh by the way ..... don't forget that trucks use often 2 x 12V banks ... with the heater / refrig units being fired from one etc. etc. The battery's are not different types . but generally identical.

Finally - I don't argue with the 'correct' battery information about designs for certain jobs etc. - far from it - but in all the years I have found that in my case and many others I know it is not strictly necessary as the batterys rarely are discharged enough to make that difference.

Sorry but I shall carry on thank-you !!

Re: My bank ....

Hi Nigel

You sound a little lit up there. I did say "If by cranking batteries you are talking about batteries designed for use on service vehicles with heavy electrical loads then I have some sympathy with your claim." For anyone with light and casual electrical loads I have no problem with that.

But I have to say that in cycled service, use of good deep cycle batteries will win every time and they will cost more than 10 pounds more each than a cranking battery. Also, an average cruising vessel will not get by with the 120 Ahr of battery capacity that you state whatever kind it is.
