Our take on the Interstate Mega-Tron Plus Automotive Battery MTP-24

The Interstate Mega-Tron Plus MTP-24 is a Group Size 24 flooded lead-acid car battery rated at 750 cold cranking amps and 130 minutes of reserve capacity. It is Interstate's top flooded battery, built to match original equipment specs and aimed at cold-to-moderate climates where strong cranking matters. Against AGM rivals it is the simpler, lower-cost chemistry, but it gives up some deep-cycle tolerance and vibration resistance. The 30-month free replacement and six-year performance warranty is longer than many budget batteries offer.

Questions and answers

Is the MTP-24 an AGM battery?
No. It is a flooded lead-acid battery. If your car specifies AGM, such as many start-stop vehicles, choose an AGM instead.
What does Group Size 24 mean?
It is a physical size standard: about 10 1/4 inches long, 6 7/8 inches wide and 9 7/16 inches tall. Check that your car's battery tray and hold-down take that footprint.
How much reserve capacity does it have?
130 minutes. That is the time it can run a typical load if the alternator fails, which is competitive for a flooded Group 24 battery.
What is the warranty?
30 months of free replacement, followed by a six-year performance warranty. Keep your receipt, since replacement claims usually require proof of purchase.
Will it fit my car?
Only if your car calls for a Group 24 battery with top posts in the same layout. Match the group size and terminal position to the original battery before buying.
Is it good for cold climates?
Yes. 750 CCA is strong for a Group 24 flooded battery and suits cold to moderate climates. Extreme cold or high electrical loads may favor an AGM.
