Battery internal resistance is different
A Guide to Understanding Battery Specifications
• Internal Resistance – The resistance within the battery, generally different for charging and discharging, also dependent on the battery state of charge. As internal resistance increases, the battery efficiency decreases and thermal stability is reduced as more of the charging energy is converted into heat. Battery Technical Specifications

Battery With Internal Resistance
Battery With Internal Resistance. When a battery fails, it is typically because it has built up enough internal resistance that it can no longer supply a useful amount of power to an external load. If you measure the voltage of a failed battery which is disconnected, you will usually find that it has a nearly normal voltage, so that a voltmeter is not a useful tool to …

One of the urgent requirements of a battery for digital applications is low internal resistance. Measured in milliohms, the internal resistance is the gatekeeper …
10.1 Electromotive Force
We see that the increased internal resistance has significantly decreased the terminal voltage, current, and power delivered to a load. Significance The internal resistance of a battery can increase for many reasons. For example, the internal resistance of a rechargeable battery increases as the number of times the battery is recharged increases.

Battery Internal Ohmic Measurements Explained
That is why different battery testers may produce different readings for the same battery. It also makes it difficult for battery manufacturers to specify an impedance or internal ohmic value for a battery, as they would need to list a number of values for the different testers on the market.
