Index of reviewed batteries? Comments?

mAh if possible would make most sense as that is how everything is rated to begin with….Thanks for all you do!

wow, you really have all the data! That is amazing.

One use case I see is that people will most likely look up your battery reviews to purchase a new set for flashlights, bike lights, shop lights or other products. They probably want to know whether the batteries will fit into a specific light, charger or other product.
There might be three scenarios:

- one type of user DOES know which length will fit because they know how to measure. That customer would want the actual length and can then buy the battery via your link.

- the other type of user has a product and has no way of measuring the length or size. However, they do know what type they already have and use. So a size comparison to another, existing cell would be a great option (same/less/more).

another user has no idea what they need, so they would want to know what to buy in batteries based on a review they found online.

Let’s see what others have to say as well - again, thanks for all of your work.

I have the data from the info box in my reviews and all the logfiles. The table uses the logfiles for all the capacity values, because the info box did not include the high currents or capacity at a specific voltage.

Length is based on button top and protection, i.e. if you know you want a protected button top you already have defined the length (Mostly).
That is also the reason I did not include length, because I already have button top and protection columns.

If BT and protection give you the length then you can omit my idea of adding anything else. I was assuming that all BTs, protective circuits and/or other features are all different!

They are different, but not that much.

Thanks for your work HKJ
Will this replace or be complementary to your graphics?
Thanks!

It will be complementary, I plan on have links to the comparators at the top of the page and each battery name links directly to the reviews.

The idea is to use table for a initial selection of batteries, then go to the comparators and reviews for the final selection.

mAh looks this way:

I believe it looks more messy than Ah, the point makes it easier for the eye to see the first digit.

There is, of course, a solution for that:

This means the options are:

Ah
mAh
mAh with a space between A and mA, this will probably not work if copying data to a spread sheet

There is no sort function, if anybody knows how to get sorting with “TableFilter”, please say.

I never used TableFilter before, but if it’s the TableFilter I found in Google it doesn’t look too difficult:
TableFilter examples
Sort with default data types (you have to click the column in the table header to sort)
Sort with a button
Sort a custom column type

cclight · 2019-01-11T21:26:15.000Z

I prefer Ah as well, and real length. Relying on usual values for BT and protection is not enough for a tight fit. Differences need more work than real length.

I will need to look at this, it may help me a lot.

The real length is never far away, you can always go to the review with a single click and see my measurement. On a PC you just need to place the mouse over the battery name and my info box will be shown.

HKJ, thank you for your great work!

- real length in mm please

use mAh because there is less hassle with , and . as decimal separator.

(Despite IMHo mAh and 1000 is wrong. I would prefer Ah because mAh is marketing to get bigger numbers. Hey why not use nA to get even bigger numbers)

I disagree, it is not usefull when you have a lamp which takes only short cells.

I had a Utorch UT01 it takes only unprotected 14500, a typical protected 14500 is too long.

But there are a few protected which fit. eg. Xtar 14500 is only 0,3mm longer

nkon.nl

XTAR 14500 800mAh (geschützt) - 1A - 14500 & 16340 - Li-ion -...

.

Filtering about real length is verry appreciated.

I think we get similar problems with protected 21700 (tight tube, battery too long) I don’t have the impression manufacturers have already settled on tube dimensions.

I looked at sorting again (I had tried before) and found out what my problem was.

It looks slightly different now, but sorting works and I discovered that “!important” can be very useful in CSS.

I am still not sure about the length, with the raw length it is basically impossible to make good filters, except if people has to write mathematical expressions. The style I use where it is possible to select one or more predefined values would not work.
If you selection is down to a few batteries it is very fast to check the length, just move the mouse marker over the battery names. I use the same style of popup as on my other tables, this time with the info box.

Another add-on to tableFilter makes it possible to show/hide columns, I have played some with it and increased the number of columns. This means that a screen need to be 5000 to 6000 pixel wide to see all about 70 columns.

To avoid that I have made it easy to show/hide columns. It was a bit of work because I had to get rid of the plug-ins user interface and supply my own.

Only disadvantage with this is speed, initializing is a bit slow, but I tried it on a smaller computer and a tablet, on both it worked fast enough after loading/initializing.

And with this setup there is no problem including both length and x-length.

wow - thanks! Looks great.

spideroz · 2019-01-14T09:44:07.000Z

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.

hodor · 2019-01-15T01:37:24.000Z

Great addition to an already awesome resource

hodor · 2019-01-15T01:43:42.000Z

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.
