Most Helpful Customer Reviews

The Optima 8037-127 D27F YellowTop Starting Battery I purchased is now safely installed and charged in my 2005 Toyota pickup. The order was delivered quickly and safely. A similar was installed in another vehicle and has served well for several years. Although this new order came with the with enough charge to start my truck, I put a 2 amp charger on it to bring it to full charge. Shen removing the charger, I noticed a little round red sticker on the battery top with 5/15 printed on it. Perhaps I am misinterpreting, but I think this battery is already a year and a half old. It may not effect the length of the warranty, but the factory battery in my 2005 Toyota is just now being replaced after 11 years. This new battery was clearly unused, but I am not certain about it's age? Perhaps the seller can fill me in?
This was the best battery I have found for the intended use. It combines a deep cycle with the power to start. Now made in Mexico and has gone downhill. Will not hold a charge even with no load on it. Consider carefully buying online as it is nearly impossible to return or get replaced under warranty. Optima is zero help.
