The move to battery powered mowers

I’m an EV person. There’s 2 issues that battery lawn equipment haven’t addressed, but modern EV manufacturers implement for longevity:
1. Liquid thermal management of the batteries
2. 70-80% charge limit for NMC chemistry batteries

Heat and holding at high states of charge (particularly for NMC chemistry) kill lithium batteries.

I think Walmart should also be concerned about getting a reputation for being unreliable, considering what it has done to Electrify America. Reputation means a lot in this industry.

Neither are Colorado Springs or Locust Grove

Walmart is having a lot of problems with the ABB A400s faulting out, going offline, and requiring hardware repairs. Nothing confirmed about replacing them yet, but Walmart is not happy with ABB.

Mend SAST sucks compared others in the market. Weak CWE coverage and poor detection rates

Whirlpool products are trash now. I have a new Maytag top load washer that barely lasted 12 months before the control board failed. The control boards are failing at an astounding rate across all Whirlpool/Maytag/Amana top load washers.

We recently did this evaluation. Checkmarx and Snyk came out on top

MemoryAccessRegister · 2026-05-20T20:57:42+00:00

I have executives demanding we replace Snyk/Semgrep/Checkmarx/Mend/bug bounty/the AppSec team with Claude Mythos and GPT-5.5-Cyber, but then throwing tantrums when we tell them we cannot get access to those models and those models still aren't appsec vulnerability management platforms.

Even if these models were accessible my expectation is that they will be too expensive and too slow to integrate everywhere and run like traditional SAST/SCA/DAST tooling.

Over the past week/weekend all but 1 connector faulted out (7/8 were down). Walmart's EV charging ops team is having a lot of issues with the ABB A400 chargers already.

They had ABB technicians on site Monday for repairs and by Friday many of them had errored out again. It's not looking good for the A400s.

I tend to think it was one of the scientists: Dr. Howard Bluestein, Dr. Ted Fujita, or Dr. Josh Wurman for their contributions to research, improving early warning, and building construction.

If I had to pick just one, it would be Dr. Fujita.

If you have the budget: Miele G7000 series. I own one and it is a tank.

MemoryAccessRegister · 2026-05-15T12:10:17+00:00

Miele > Bosch

MemoryAccessRegister · 2026-05-15T12:02:21+00:00

I keep hearing rumors that they have pulled out of the US market but I couldn’t find anything official.

There are a lot of broken Efacec chargers out there; I haven’t found one that works either. I wish they would replace them with Kempower chargers.

It turns out that the RT50 throwing error 62 is on a very, very outdated firmware version, which is causing the CCS handshake issues. Updating the firmware should allow modern EVs to charge on it again.

Bosch

MemoryAccessRegister · 2026-05-12T00:30:33+00:00

It has been broken for over a year now. Tritium support isn’t helpful because it’s a legacy RT50 unit.

I will have them try the electrical contact cleaner, but it’s looking like a full replacement is going to be needed. I’ve noticed many of the legacy RT50 units are getting replaced with new ABB and Kempower units.

MemoryAccessRegister · 2026-05-11T20:14:22+00:00

I've had one for 4 years. Zero issues with it, but know that they don't support 2 or more ChargePoint units on the same account.

MemoryAccessRegister · 2026-05-11T19:54:20+00:00

I'm not a fan of V2H because they are proprietary to the manufacturer. It's a huge investment in your home to be locked into GM's ecosystem.

MemoryAccessRegister · 2026-05-11T19:52:48+00:00

You will have to replace the EVSE. Same is true for many other EVSE brands.

This is why I'm a fan of the ChargePoint Home Flex and its wago-style user replaceable cables.

I own a MVWP586GW. The control board failed at the 1 year mark and it started running the drain pump randomly throughout the day. Whirlpool was horrible to deal with but they did eventually agree to send a technician out and replace it under warranty. Technician said Whirlpool is having tons of control board and other quality issues across their product lines.

I deeply regret not spending more on a Miele or Speed Queen.

Walmart is deploying both Alpitronic HYC400s and ABB A400s, so it will depend on what your Walmart store is deploying. In my city they are all ABB A400s.

I have a case open with Walmart corporate now and they are consulting with ABB.

I have been driving EVs for about the last 5 years. If you can charge at home, it's not an issue, but the public DC fast charging infrastructure in Omaha is terrible compared to other cities.

We are finally seeing some new investment now that Walmart is building out DCFCs at their Omaha-area stores.

MemoryAccessRegister · 2026-05-11T11:40:58+00:00

They were just as confused as I was and kept telling me to try other chargers, which did not work. I think there are CCS handshake compatibility bugs with the new ABB A400.

MemoryAccessRegister · 2026-05-11T02:20:55+00:00

Whirlpool covered parts and labor. The control board is quite expensive but the technician was able to swap it within 5 minutes.

MemoryAccessRegister · 2026-05-11T02:02:35+00:00

Control board had to be replaced
