Nice, thank you for that, very useful!
Your review/test are awesome thanks for that too, having the ability to search your database for specific criteria is really cool. 
Great addition to an already awesome resource 
Also, sizing is good. Perhaps something to consider would be a rating system for batteries, similar to what you have for chargers? This would need to be applied to each battery for it to appear in the index so may not be feasible for existing reviews.
