So far so good, but I will say there were two batteries on the rack, one was made in June 2106 and one (which I bought) was made in August 2018. Since I purchased the battery in Jan 2019, the 2016 may not have still have had a charge. Fortunately, I noticed the mfr date and purchased the most recently manufactured battery. I think Home Depot should remove the older battery on the off chance that someone may buy it to replace a dead battery only to find out that the "new" battery will not start the vehicle.

Same price and better value than Interstate battery with 13% more cold crank amps and is considerably heavier thus more power. Time will tell how good it is.

      51R Battery Do not buy this brand
      I have bought this battery back on October 31 2014 and use it for moderate use, Parked the car for a month and after that the battery died, recharged overnight and seemed to turn and start the vehicle and i thought that the problem is solved, but the next morning the battery could not crank the engine and was giving me the sound (you know "TRRRR-TRRRR") so i measured the voltage with multi meter and it shown 10.45 volt, so i will take it back because the battery is only 7 month and 10 days for warranty replacement.

      Feel the difference already.
      I bought this battery to replace the 4 year old OEM battery in my 2011 Honda CRV. It has made a difference already in the idle because the electrical system was carrying the load of a weakened battery. I was pleased with the $12 core, because the OEM battery isn't dead it is just weak, but maybe it can light a few 12 volt lanterns during power outages.
