IвЂ™ve seen quite a few pretty poorly done resealing jobs. There are advantages to having assembly done in a factory setting by a guy or gal that does nothing but assemble batteries all day long. The success of this вЂњfixвЂќ depended a lot on the technicianвЂ™s skill and the effort he put into the job. They were all recalled to be cleaned and sealed. The Gen1 batteries had a lot of problems with electrolyte leaking past the terminals. Did the recall have anything to do with battery failures? At first most of the batteries were covered under warranty, but it has been 12 years since the last 2003 was sold, so none are covered anymore. WeвЂ™re in Berkeley, so we have a lot of Gen1s still coming in and weвЂ™re still seeing at least one bad battery per month. That may seem like a lot, but itвЂ™s a drop in the bucket when compared with other types of expensive repairs. WeвЂ™ve seen a lot of Gen1 Prius battery failures IвЂ™d guess weвЂ™ve seen over 100 at this point. WeвЂ™re now seeing Honda cars coming back for their second battery replacement out of warranty.

To HondaвЂ™s credit, the bulk of them were covered under the standard or extended warranty. So far, weвЂ™ve seen many Insight and Gen1 Civic batteries fail. I still agree with most of what I said way back when, but it youвЂ™re just wondering how long a hybrid battery lasts, and arenвЂ™t interested in the technical details, click the link for a newer, less-technical article. The level of concern about battery packs is massively disproportionate to the actual rate of failure. Let me start this article by saying, battery problems are very low on the list of problems weвЂ™ve found on the hybrids we repair. These are questions that have concerned many of our customers who were either considering buying a hybrid, or had already purchased a hybrid. How much will a Prius battery cost to replace?

How can you tell when a Prius battery is beginning to fail?
