Why do car batteries have to be the same Ah?
If you had a massive stereo then you’d be fitting a battery with a higher AH rating to cope with the extra current draw. You’ll probably find it spins over and starts much quicker! Rep: ? I believe the first number is the number of Amps the battery will allow to be drawn from it.
When did I put the new battery in my solstice?
Well, I am also back at it….put the new battery in six weeks ago, everything ran fine and have had the car out on multiple occasions. In fact drove it on the 4th of July, went out yesterday morning and turned the key, click, no start, everything lights up, good power et….but no joy. Charged the battery and it read 12.9 volts, but no start.
Is it worth it to get a new battery?
Another (new) battery is expensive — and a lot of work to change. You can hook up an ammeter for virtually free (well OK, you may have to spend ten bucks for a meter at Harbor Freight). If there is no leakage — or you can prove the alternator is working — then get another battery. Click to expand…
Can a car battery last longer than an hour?
If that number is higher, it can obviously give more amps in the given hour, but if you lower the drain to 43 Amps, it will last longer than an hour. The maths can be a bit tricky, but it’s useful in every day life.
Is it better to buy a new battery or replace an old one?
Since you are thinking of buying a new battery, needing to expand capacity, and inevitably will have to increase charge capacity it is time to re-evaluate. You probably would be better off buying one new battery of greater capacity (or two 6 Volt units) than adding another of the same on to the existing. Thanks a lot for the detailed reply.

Can You parallel an old battery with a new one?
to make it clear, you can parallel a new battery with your old one, but as soon as you do the new battery will take on the same age and capacity characteristics of the old one. you can also parallel an identical older battery to your present old battery, but whichever is worse will be the standard for all.
How to keep an old lead acid battery around?
Westbranch’s suggestion of the A-B switch is the most practical way of keeping the old one around ’til there’s no more life in it, but you will have to remember to monitor both batteries and make sure each gets regular charging. If you forget and let ‘B’ sit on its own it will discharge, sulphate, and die.
