Geez Louise, I was feeling my age (70 in January) today.
I replaced our RV’s two engine batteries (12V Interstate 31-MHD) and four house batteries (6V Lifeline GPL-4CT).
I thought it would be a 1-hour job. Two-and-one-half hours later I was done. Really done. All tolled I schlepped 768 pounds of lead (removing 384 pounds of old lead and then lifting in 384 pounds of new lead).
I tried to start our Newmar last week, and it wouldn’t turn over. A 12V battery should actually be over 12 volts . . .
However, my engine batteries weren’t even close. Then I remembered that they were probably over 10 years old . . .
Since I had to replace the engine batteries, I thought it was also time to replace the four, 7-year-old house batteries.
Heavy and expensive, but this should be the last time.
