SCHOOL BUS BATTERY MAINTENANCE


School Bus

School bus battery maintenance is similar to military fleet requirements, where a vehicle may sit for months, unmaintained or unstarted. Battery sulfation and internal discharge will occur, and frequently causes problems. We have used the patented pulse technology for years, and when properly selected and applied, it does what they say it will, without involving chemicals. There are battery charger/desulfator units, solar powered desulfators, multi-bank desulfator/maintainers, and desulfating-only units, as well as high end military units. Some involve removing the batteries for inside shop maintenance, and some permanently attach to the vehicle battery in the storage area. So check out our selection, or call with specific situation requirements or questions.

PulseTech Desulfation (Desulphation) Technology For Buses

There are basically two types of desulfation devices we carry that would be appropriate for school bus application, what we will call active and passive, for lack of better terminology. An active device has the desulfation electronics incorporated into a charging or charge maintenance device, like a battery charger or solar maintainer, or multiple bank charger. A passive device is the desulfation electronics unit which takes power from the battery pack and pulses it back with the desulfation waveform. This involves milliamp power amounts, and is usually negligible when considering battery discharge, unless months of inactivity are anticipated. How to apply these?

The PowerPulse units are passive devices, in 12 through 48 volts. The PP-12-L also works on 6 volt batteries. Higher voltage systems can be wired in groups of these voltages. These permanently attach to the battery or pack with ring terminals, attaching to the positive of the first battery and the negative of the last battery, where system voltage is present. When used on new batteries, they keep sulfation from forming, and allow the batteries to attain a 100% charge when they are charged. On older batteries that may have sat or have sulfation issues, they slowly break down the sulfation molecules to recombine chemically and allow increasing battery capacity, and generally extending the lifespan of a lead acid battery (not indefinitely). We like to use these on larger batteries that may require some time, or any situation where AC power isn't available to use a plug-in charger/desulfator.

There are a variety of AC chargers by PulseTech that incorporate the desulfation technology. The newer Xtreme models, one and two bank, are excellent for home or shop use, to charge and maintain 12 volt batteries, such as ATV, jetski, automotive, RV, marine, or sealed lead acid batteries such as backup system batteries, and wheelchair or scooter batteries. The longer they are left on in the maintenance mode, the more effective they are on cleaning up a battery. There is the XCR-20 battery recovery and maintenance charger, which is a 20 amp, universal input charger which analyzes, charges, and desulfates. These are expensive, but excellent units. The PRO-12 is an AC powered 12 output desulfator, that has very little charge value. This may charge small lead acid batteries up to about 5 amp hour, but really is best used in a shop or store environment where multiple lead acid batteries are stored, such as a school district bus fleet shop. It keeps them charged and desulfated, at peak power, ready to go. The SC-12 with its 12 outputs at 8 amps, which we recently added, is the ultimate desulfator/charger for sophisticated applications, where multiple batteries of possibly differing type and size need to be charged, or desulfated, or simply maintained.

For buses that will have the batteries left in them, unmaintained over the summer, for instance, there are solar powered units. There is a 2 watt SP-2 unit, and a 5 watt SP-5 Solarpulse. These have a high performance unbreakable solar panel to drive the desulfation electronics, with a wiring harness. These charge and maintain a battery, and keep them desulfated.
