(Ugh can an admin change the thread title for me, please)
I contacted Antigravity batteries regarding the different amp hour options (since Doug is out of the lightweight battery kit). I was trying to figure out what the difference between the three choices were. Here's a good chunk of info in case anyone is interested:
"It is due to a combination of factors, some of which you have already mentioned, but also trying to avoid cutting down on factory battery capacity too much. We simply can't guarantee that a 30Ah capacity will work in all street driving situations and conditions, with all accessories, especially if the vehicle isn't driven regularly, if used for short drives with many stops and starts, if used in heavy traffic with AC and other accessories running, etc. Whenever the battery is pushed to its limits, overheated, overcranked, discharged, whatever it may be, it WILL shut off and go into sleep mode, and you will lose all power. For example, you are stuck in traffic, it's a hot day and your AC is running, your stereo is on... The alternator works slower at idle and low RPM and it doesn't charge the battery as fast as when the car is moving, so with a small capacity you may run into a situation where the battery is getting discharged faster than it is getting recharged back to required level, triggering the over-discharge protection, and your car simply loses power. Most modern cars, especially those with large displacement engines. come with batteries that pack at least a 60 Ah capacity. A larger capacity is better for cold starts and those unpredictable situations as well.
Now, if you have measured your car's power draw during a typical drive, and you are confident that you can get away with a 30Ah battery with your driving habits, you are more than welcome to give it a try. We would appreciate your feedback in that case, so that we can better assist future customers. If it gives you problems, you can send it back and request a warranty upgrade to a 40 or 60 Ah. You would just have to cover the difference in price."
Has anyone tried the 30 amp hour battery and had issues?
