Recharged batteries want to sit down for twenty-four hours after which be retested to guarantee they’re holding the cost. There’s no level in reinstalling a useless or dying battery.

Many consider {that a} battery is junk as soon as it has been completely discharged, however that’s completely not true, argues Larry Rambeaux, gross sales software engineer at Purkeys Electrical.  

“Flooded-cell batteries might be recharged and examined,” he says. “In the event that they cross the exams, they’re good to return onto a truck.” 

Utilizing a longtime process, all batteries pulled from in-service vehicles might be examined. Then it may be decided if they are often returned to service, returned for guarantee, scrapped, or put aside for vehicles the fleet is promoting off. 

Rambeaux recommends designating an space as a “battery room” and limiting entry to that space aside from the technician on shift in command of batteries. In any other case, it’s too straightforward for a technician searching for a battery to take one from the unsuitable pile and put it again on a truck. When it fails a couple of weeks later, the plain response could be, “‘these recharges failed us once more, we have to stop doing this. All they’re doing is costing us cash.’ That wouldn’t occur if the sorting and charging program is finished correctly,” he says. 

Step 1: Triage 

Technician locations all eliminated batteries on Pallet 1 to be sorted by the assigned battery individual. Batteries are sorted by bodily situation, age, and producer. As soon as inspected, clear all terminals with a battery brush and set up correct lead adapters.  

All batteries that cross the preliminary inspection needs to be recharged. Broken batteries are put aside for scrap or guarantee.  

Step 2: Charging and testing   

As soon as charged, all batteries needs to be load examined and assigned to certainly one of three pallets: 

Pallet 2: Batteries that cross the load take a look at and are positioned on 24-hour maintain earlier than being load-tested once more.  Pallet 3: Batteries that fail the load take a look at and are below guarantee awaiting processing. Pallet 4: Batteries that fail the load take a look at and are usually not below guarantee. Designated as scrap. Step 3: Sorting and Matching 

Good used batteries (batteries that take a look at nicely after 24 hours) needs to be put collectively in matched units utilizing the next standards to return on a tractor. Type by: 

Age (needs to be inside 6 months) Producer CCA (needs to be inside 50 CCA) 

That 24-hour maintain earlier than retesting is essential. Rambeaux says about 10% of them could have some inner drawback, reminiscent of a low-grade quick that may trigger a lack of cost.  

“It you allow them to sit for twenty-four hours, these issues will present up,” he says. “These are the batteries that give recharge applications a nasty identify.” 

It’s additionally a chance to cull a number of the oddball batteries from the system, reminiscent of those you acquired on a highway service. Even when they take a look at good, they received’t have any guarantee. You received’t wish to put it again on an over-the-road truck, so Rambeaux suggests utilizing them for commerce vehicles, or perhaps yard or native vehicles.
