Owner reviews for battery

I've had my Mach E for about four years and nearly 100k miles. I've never worried about the 80% charging and always charged to 100%. I can't tell a huge difference in the range after four years.

Currently have a MB EQS that’s fantastic for about 1/3 of what it cost new.

Also, most car manufacturers know that customers are generally bad at doing the "correct" thing, so they protect their batteries by design.

When you are charging to 100% you are actually closer to 95-97%, when you run your car to 0% it's actually 5-7%

All because it's easier to show you another number and build the protection into the system, than to change people's habits.

Well logically, at 50%, even if the light is pulling more than it should, at say 3A instead of 2.5A (which it won't be with a Convoy), then the light should run for an hour with maximum efficiency.

Nice hack. I have a Yuasa that will be 13 years old this year and still going.

The only issue we’ve had with it is recently a bunch of warning lights started popping up randomly but all at the same time. I assumed it was a wiring issue or something since none of the systems it said were disabled actually were. Dealership couldnt replicate it so it took a couple weeks of bringing it back and forth every time it happened before they were able to see anything on their end. Replaced the battery and it’s been fine since.

How's the Duracell Vs the oem? I have 6 battery to buy (2 per pack) for a similar ups (1300va from apc with same lcd).

Last December, the OEM battery died and I replaced it with a new Duralast battery from AutoZone. Fast forward to today, the car wouldn\u2019t start at all. Had to jump it just to get it running and drove straight to AutoZone to get it tested.\n\nBattery tested good. Starter tested good.\nBut the alternator failed, specifically the charging current test.

I bought a Yuasa battery from AutoPro, and they told me it comes with a 2-year warranty. After about one and a half years, the battery almost completely died. I had it tested and was told it was dead and needed replacement.

The battery is almost certainly dead.

Something else wrong with your car likely killed the battery and if that's the case buying a new battery will just result in the same problem pretty soon.
