I have a few years old non-deep-cycle automotive starting battery I've been using as my house battery in the 86 Westy. it's been acting a little flaky so I pulled it out for some testing and possible replacement. I've had some other issues/symptoms with my house battery side of the electrical system so I wanted to take a possibly failing battery out of the equation. I last drove the van about a week ago for about 2 hours with not much load on the house battery. I hooked up the battery to one of these: http://www.banggood.com/ZB2L3-Battery-Capacity-Tester-External-Load-Discharge-Type-Module-p-1058571.html For the load I used a tail light bulb with both filaments burning. This put 2.55Amps load on the battery according to the display on the above device. I set the device to stop discharging at 10.5V and it came out to about 13Ah of capacity. That sounds low to me and like the battery was either not very well charged or it's toast. I've now got it on a charger and will check it again after it's recharged. comments? is discharging it to 10.5V more damaging than any info I gain from testing it? Edward |
