Batteries & Jump Boxes

An active online discussion group of Acura owners reporting problems maintaining charge on their batteries came to a consensus that an effective solution was the use of an Optima battery. I'd owned the car a year before I began noticing the 'slow cranking' and eventual inability to start problem; particularly if I listened to the radio without the engine running; killed the battery several times before I bought my Optimax. The new yellow-top shows a marked improvement in cranking power. The car starts up right away and hasn't given me any more problems. View more reviews...

Bought this for my daughter's car at college since she does not drive it regularly. The Bluetooth connection lets her check when she gets in the car if she needs to charge the battery to use it before a trip. Very useful. It does hold a charge for several months and the app guides you through the connection process. View more reviews...

It does exactly what it's supposed to do. I definitely recommend it. View more reviews...
