What is the risk when the battery rebuilder extends a 1 year warranty - part, labor & service calls? A lot of new batteries have a 5 year warranty but the lower end priced batteries have a proration during that period - like a 3 yr fully & 2 proprated. Additionally, with every one I sold and installed I personally went over proper battery charging & maintence procedures plus charger care (cables, connectors) & features did actually explained what & when the equalizing charge is and when it should be used - my experience was that when you asked a customer what the Equalize button is & what it does 9 out of 10 did not know and I again thanked my competitors.
Just to give you an example in early 2006, I sold a used TM30 with a reconned battery to a small retail flooring company in the town I live in - I knew the owner, we coached dixie boys (like little league) baseball 15 years ago. Useage 1-2 hours per week. Less than a month ago I saw him & inquired how that truck was running & he said "mighty fine" no major issues. I never was embarrassed by selling a reconned battery in the "right" application and I enjoyed the commissions that came with happy users and so did our used truck manager.
I have seen "other" lift truck companys put a reconned battery in an operation where the trucks running time averages 4-5 hours/8hr shift* and they flunked again I thanked my competitor.
*That's heavy duty usage based on my experience - freight companies such as ABF & Roadway average 4.5 lift truck hours/8 hour shift at their break bulk terminals and food distribution companies like Kroger have similar results - I've dealt with all these companies in my career. Most lift truck operations average about 3 hr. per/8hour shift. End users/owners generally have no clue as to their average daily lift truck usage.
