Battery Tips

EV fleet workshops are busy places. And, of course, the work usually comes in waves and rushes, most often just as your technicians are relaxing and looking forward to a weekend off. Typical. So, what if you could predict those battery problems earlier? That’s where a comprehensive battery maintenance schedule comes in. And the more

Battery imbalance can be a vehicle’s silent killer. It’s a natural process that quietly works away until one of the 12-volt batteries in your 24-volt system gives up before its time, often taking the other one down with it. Battery balancing is the key to stopping it. Here at Rotronics, we’ve made batteries our business.

The odds are that the two 12-volt batteries in your 24-volt system came in pairs. A technician probably installed both on the same day. They’re likely the same brand, and they should be exactly the same spec. But by now, they’re very rarely in the same condition as each other. Here’s what you’re almost certain

The battery packs in your EVs are made up of hundreds (and in some cases thousands) of individual cells connected in series. The more cells connected, and the higher the voltage of each cell, the higher the overall pack voltage, which powers the vehicle. However, keeping all those individual cells balanced – meaning each cell

Electric vehicles (EVs) store chemical energy in their battery packs, which is then converted to electrical power to drive the wheels. These battery packs are complex assemblies of hundreds of individual cells working together. When all these cells are balanced (that is, they all have the same state of charge and state of health), your

Batteries don’t usually fail all of a sudden. They wear out slowly, often without warning, until one day the engine won’t start. Every fleet has dealt with the unexpected non-starter on a tight schedule. But what if you could predict battery lifespan more accurately, get replacements lined up in advance and significantly cut downtime? How

Vehicle battery problems often aren’t just about low charge. Most of the time, something inside the battery is wearing out or failing. That’s why knowing how battery testing works helps you spot problems faster, especially when you already know your vehicles and how they’re used. This guide explains the main types of battery testing, what each one

A truck engine in your fleet doesn’t start. The driver’s already behind schedule. There’s pressure to find the fault, fix it fast and get back on the road. And it’s not even the first tea break on Monday. As you know, the battery is more often than not the problem. But before you jumpstart it

You know the drill. Your parcel delivery driver gets stuck outside a countryside farm. Your bus has to let all its passengers off. Your ambulance won’t start. The consequences are immediate and severe, and it all comes down to a dead battery. But here’s the kicker: most battery failures are preventable. In fact, the right

As a fleet manager, there’s something strangely unsettling yet completely normal about that unmistakable sound of a car struggling to start. When that sound happens, the battery is usually the first thing you think of. But before it gets to that point, there are usually a few telltale signs that a battery is heading for
