Hello, I'm looking to switch out the battery in my car with preferably an Optima Yellow Top or other suitable battery but cannot find any information about this battery size and specs to point me in the right direction. Appreciate any help, thanks.
19A minimum..How about connecting two Brailles in parallel. With that enough space left...you'll get the same voltage flow, but a sure slam dunk on current output.Perhaps we need a sticky on the Electrical Forum for battery specs. The manual says a replacement battery has to have a minimum of 19 amp hour rating for adequate power drain capability during extended non-usage periods, or accessory use when the engine is off. I'm not sure what minimum cranking amps and cold cranking amp specs are for the stock battery. Perhpas somebody on this board knows how to test that?
Not helpful for the original posters specific needs mentioned above, but for others, I posted a separate thread in this forum on using a Braille B2015 lightweight (AGM) battery to save 15 lbs of weight. It's working fine, and I expect it to have double the life of the stock battery, which helps with the extra cost over a regular battery. My 2001 miata had a factory Panasonic AGM battery that lasted 9 years, which apparently is pretty common. As mentioned in that thread low cold cranking amps is the only potential concern for non sunbelt state locations.
I could use a Braille here in SoCal, but $199...and a gaping odd-like looking battery space (could be better if enough, for a 2nd Braille) that needs to be "filled" (insert connotation here, :lol. Ouch!$199 each, not cheap, but you're right, you'd end up with 40 amp hour capacity and decent cold start ability. LoL. The stock tray isn't quite big enough for two side by side though...
So I'm confused, how does an alternator mischarge a battery? I understand if the battery sits around a long time and needs a separate charge to happen could be screwed up, but otherwise if it has the same amphour capacity as a regular battery for the application then it never needs separate charging and should be fine right?I like AGMs in their proper application but IMHO a car starting battery isn't one of them, with one of the biggest problems being proper charge control that is utterly necessary if you want good service life.
