Defective KOP battery

[PeterR]

We got a battery in the KOP like everyone else. However, this year’s battery is already bad. The battery beak says so and whenever we use it we get brownouts in the first minute or two from just regular driving.

We have never discharged the battery more than 50% and the battery has less than 10 cycles on it as we have a lot of batteries and have not driven much. We also treat our batteries well and still have good batteries from 2012 on the comp bot.

Is there any way that we can get a replacement? Or is it too late?

I don’t think I can give any advice myself, but there does seem to be a trend with some new 2019 batteries drastically underperforming. If you haven’t already, I’d recommend looking at this related thread that was on here quite recently:

Battery Warning

Hey, this is a notice to everyone. I don’t know if it is all of the kit of parts(KOP) batteries or just ours. So I am part of Team 2619 The Charge, This past worlds we did a seminar in Detroit about our way of testing batteries and stuff like that. Then this year when we went to test our batteries we found that the KOP battery was worse than a 5-year-old battery. The battery was an SRS brand battery. We have not used any of this brand of batteries before. We also did compare it to a five-year-ol…

We were browning out with the kop battery, we have since disposed of it. They are no good. -2549

I don’t think FIRST will give replacements considering I haven’t heard of anyone with a good KOP battery this year. Hopefully they don’t get batteries from the same supplier next year.

Yep, our alliance partner had issues browning today. We ended up loading them some of our batteries (varying from 2017-2018). Stopped all issues, they were using all new ones.
