Specific Gravity Chart

dagr51 · May 2009

The only specific gravity charts that I can find have a very broad range - 0%, 25%, 50%, 75% and 100% SOC. Does anyone know of a chart that is more specific - 80%, 85%, 90%, 95%, etc.? Will simple extrapolation suffice? Thanks!

Re: Specific Gravity Chart

You will not find much that is any closer unless the battery manufacturer happens to publish one, since the SG of a particular brand and type of battery can differ. And even there, the SG might differ depending on where it is sold - what temperature range.

Here's a chart with excellent numbers, if they are accurate, that is:

40% -- 1.175
50% -- 1.190
60% -- 1.202
70% -- 1.216
80% -- 1.230
90% -- 1.245
100 -- 1.265
