Battery condition scores explained

The Hybrid Battery HealthCheck will give you a battery condition score. Here's what they mean:

Poor condition

If your battery is in poor condition you may notice a range of symptoms such as the vehicle not holding a charge or provide consistent voltage output. Also the capacity of the battery overtime has significantly reduced and it suffers a high self-discharge rate, losing its charge quickly when not in use.

Be alert to the more frequent or constant use of the cooling fan as the battery turns almost all charge into heat. It is important to note that if a battery is showing these signs it's time to replace it.

It is critical you visit your local automotive professional or contact Infinitev.

Average condition

A battery in average condition is one that still holds a charge and provides consistent voltage output, but may not perform as well as a battery in good condition. It may have a slightly higher self-discharge rate and lose its charge more quickly when not in use. The capacity of the battery may have degraded, and it may not be able to hold as much of a charge as it did when new.

You may notice that the cooling fan is more active as the battery turns the extra charge into heat. Your battery may still be used but should be monitored more closely. Should symptoms or battery performance degrade visit your local automotive professional or contact Infinitev.

Good condition

A battery in good condition boasts a consistent voltage output and holds a charge well.

It shouldn't have a noticeable decrease in performance and capable to retain at least 80-90% of it's capacity after several cycles. The self-discharge rate should also be low, meaning that it should maintain its charge for a longer period of time when not in use.

Lastly, the cooling fan that manages battery heat from extra charge will rarely come on.

Should you notice a decrease in battery performance, please visit your local automotive professional or contact Infinitev.

A score of 60 or more means the battery is in *good condition. The battery boasts consistent voltage output and holds charge well. Good news :)

A score between 30 and 60 means the battery is in *average condition. Keep an eye out for a more active cooling fan, as extra charge (no longer held) is turned into heat.

A score below 30 means the battery is in *poor condition. The capacity of the battery has significantly reduced and thus suffers a high self-discharge rate. Visit a local specialist to get the car checked.

Hybrid Electric Vehicle Battery Replacement Anxiety, or HEVBRA in short, refers to the concern among hybrid owners about the performance and longevity of their batteries. This can be a significant source of stress for them.

Anyone looking to purchase a used vehicle will also want to know that there are no surprises under the hood (or back seat, more like).

We recommend you take your car to a licensed professional for a proper and safe diagnosis of the battery. If your regular mechanic cannot help you, we can connect you with one of our specialists near you.

Keep an eye on the battery. If you notice the fan becoming noisier than usual, or the battery draining/reaching full charge more quickly, it's probably time to get a professional to take a look at the car.

There are two things batteries don't like: heat and sitting idle for long periods of time.

You can help manage heat by ensuring the fan on the battery is cleaned regularly by your mechanic and by keeping the air intake clear from obstructions. Keep reading for more general servicing tips.

Regular exercise is also a good idea. Hybrid drive batteries self-discharge when they are not being used, which over time may impact the performance of the battery.

Extremely happy with the level of service from John and Joel. These guys have a deep, technical knowledge of Hybrids and batteries, and they took the time and care to answer our questions. Joel even showed us the real-time ECU data during a test drive with his laptop once the new battery was installed.

Very competitive on price and better warranty terms than Toyota. Highly recommended.

Late review but a massive thank you to John and his team for resurrecting my 2007 Prius. John knows batteries like Google! So knowledgeable and informative. Patient and accommodating. He managed to get me a refurbished battery pack considering he has such a long list of customers. No more triangle of death
