Excessive word repetition or "keyword stuffing" can make your page less likely to rank for the overused words. If you are trying to rank for phrases containing "price", "voltage", or "rating", you product lists are going to make it harder.
As long as your page is appealing to users and doesn't seem stilted or spammy, the page as a whole is unlikely to get penalized from ranking for all search terms. You will still likely be able to rank for name of the product itself.
The best way to know if you look spammy is to ask people that are not associated with your site questions like:
- Does this page look high quality and professional?
- How would you react if you landed on this page after searching for X?
- Is there anything you see on this page that you don't think anybody would be interested in?
Using a word on lots of different pages will make it appear on the content keywords list in Google Webmaster Tools. I have several sites where using a word in a template caused a word to be at the top of this list, despite the word being tangentially related to the topic of the website at best. This has never caused any problems for any of these sites. We never ended up ranking for those keywords, nor did we notice any penalties in general.
