Not Bad!

I purchased 1 of these to replace my battery in a 1997 Suburban. With heater on hi, stoped at a light at night, my voltage still drops up to about 13 or lower but no problem with heater off. Suburban pools a lot of juice it has 3rd Heating and Air. Also have 2 cheap 2000 watt amps, cheep 10 fraud capacitor 4 8ohm Kenwood 12s wired good but have not done the Big 3 ground. I would say it's about the same as a red top. I left this stinger battery for 14 hours with the key turned back started right up the next morning. I've only had it about a month I think I got it for less than 300 and with adapter to make it from top post to side post included they worked okay but like all batteries make sure you don't strip terminals. I am a fan of the red top batteries I had one a few years ago and it worked great. I don't know why I went with something different but the Stinger works great too

Incredible

Such an awesome battery for a stock replacement. Stabilized my system voltage really well when bassing hard and made those low notes really come through. Running 2 nvx vcw154’s in a ported box. Sounds great
