Prius Hybrid Battery Report

[Ultimo]

Hello Peeps,

One of my friend is going to buy a used hybrid (2013) & got this hybrid battery report.  Actually we are clueless what it says. We are more than grateful if any one could shed some light on this.

TIA

Well, judging by the looks of the report this seems to be a Toyota hybrid and scan report by Toyota Lanka, isn't it?

This report has detailed out the individual battery cell voltages. The battery would be in good shape if all individual cell voltages are closely knit together, without much deviation. As per the report there seems to be slight variations among the cells with the maximum being 14.47V and the the minimum being 13.9V.

Has the battery being replaced previously or any work done on it? Since, this is a 7 year old battery you are talking about there can be certain deterioration on the cells causing them to hold a reduced amount of voltages over time.

Thanks for the reply.

Ya it is a toyota report.This is a report given us by the seller. Actually we dont know about its past,. Can we use this battery for good 3,4 years?

Well, no one can actually tell really since you don't know about the history of the battery. The thing with Toyota hybrids is that they don't give an Effective Usable Battery Capacity percentage wise as in Honda hybrids.

However, as I mentioned in the above comment; since, this is a 7 year old battery (may be some sort of repair or reconditioning had been performed by the previous owner(s), at some point of time which you are not aware of) you are talking about there can be certain deterioration on the cells causing them to hold a reduced amount of voltages over time. This would reduce the performance of the hybrid battery. This would happen to a new battery as well over time. I've seen battery cell voltages of high 16V in some Axio and Aqua hybrid scan reports.

Anyhow, a brand new hybrid battery at Toyota Lanka would cost around 400,000/= for a Prius. So, keep that in mind. If you don't plan on running high miles under your ownership tenure, it might not be worthwhile as you won't be able to offset the above battery replacement cost via fuel savings.

Battery block voltage not matters (whether its 14 V or 16 V because it depends on it's "State of Charge") but the voltage difference matters. Difference between max to min 14.38 V - 13.99 V = 0.39 V (~ 0.4) is bit higher (for a vehicle at parking position). Probably this may be it's original battery and nearing it's final stage. If no other issues, and you are intended to buying for heavy use, no harm buying the car keeping Rs. 400,000 margin for battery replacement.

thanks for the straight fwd answer

State of Charge 39% is max.possible level (ex:after fully charging) or the charge available at the time of this measurement?

It is the level of charge available at the time of scanning..

Hi @Dee Jay

if the SOC is 48% and battery is not replaced in 2015 aqua. Do we need to consider to change or not ?

Hi!

The SOC does not indicate the condition of the hybrid battery. It only indicates the charge level at the point of the scan.
