Listers,

 Because my nominal endurance load is about 8 amps, my original 6 amp load test was not representative of my needs. So, FWIW, I just ran a 9 amp endurance test on my replaced RG battery. The results of both the 6 amp and 9 amp tests are attached. After fully charging the battery, I added another automobile lamp in parallel with the earlier load to get approximately 9 amps. The starting open circuit voltage was 12.95 V. The initial curremt under load was 9.73 A. I discontinued the test after 85 minutes when the voltage wa 10.01 V and the current was 8.46 A.

 

 I have forwarded my original test comments for those who did not see my original post or to refresh others on the first test.

 

 Regards,

 

 Richard Dudley

Hi Richard,  

I have been looking at batteries to get an extended discharge cycle for an EFIC conversion and found that “Full River” batteries are well represented and publish full performance details. Their DC series are for long flat extended deep discharge with less cranking power. I have their HGL series general purpose sealed AGM battery which has good cranking as well as extended discharge. I chose an HGL 33-12 with a discharge of 3 hrs (at)9A for my application; weight 11KG and max discharge is 495A at 77deg F. It is an  overkill endurance but I need the cranking amps for the Jab 3300 and long leads and the weight is right for my CG..  

It cost AUD 95.00 (normally RRP AUD 130) purchased on line. Life is claimed 6 – 10 years depending on application. I think by comparison the Odyssey has a bigger CCA but less extended discharge performance. We are having warranty problems with Odyssey down here.  

According to the chart the Full River HGL 18-12 has a discharge life of approx. 2 hrs (at) 8A and weighs 6.3KG.  

Cheers  

Peter

Hi Peter,

 It appears that your 33-12 is about 2X in weight and about 2X in endurance comparaed to my $60USD 18AH 13lb battery and your 18-12 is about the same weight and similar AH. I am not sure of the service life of my battery. I have arbitrarily changed it in one year. It appears, though, that after one year of service it still has approximately the endurance claimed by the spec. sheet. I may do the test on my new battery at my next annual and then decide whether to replace it or not. Here in Florida where the temperature is usually above 60 deg F, these batteries crank smartly my O- 320 every time.

 Best regards,

 Richard

Richard I am in Queensland similar climate to Florida, the only place to be. ! Seems as if you could get quite a bit more service life from the battery, just test to confirm each year.

Peter,

 >From my results, I believe you are right. My annual is/was in February. I will do the test on my current (new) battery next year to confirm its endurance and avoid the cost if it looks as good as the one I replaced this year.

 Thanks for the comments.

 Richard
