Here is a summary of battery replacement for the 2014 N-BOX (N/DBA-JF1). Panasonic CAOS N-M65/A4 CAOS Blue Battery Blue Battery for Idling Stop Vehicles https://www.amazon.co.jp/gp/product/B... Battery Model Name https://panasonic.jp/car/battery/supp... The battery terminal of the genuine N-BOX is [L], but even if you accidentally purchase an R, the N-BOX has a generous cable length so that it will fit. However, since the [L] battery can be positioned so that the cable does not cross over the battery, K's deliberately purchases [L] batteries. Panasonic's car battery "N-M65/A3" has been upgraded to "N-M65/A4". The main differences are the following three points. 1. Idling stop life is about 1.5 times longer The A4 has an idling stop life of about 1.5 times longer than the A3. This is because the newly developed "Premium Charge Control" and "High Performance Separator" have been adopted to improve charging efficiency and durability. 2. Improved maintenance-free performance The A4 has improved maintenance-free performance compared to the A3. This is because the newly developed "Maintenance-Free Plus Technology" has been adopted to suppress the decrease in battery fluid and reduce charging frequency. 3. Improved charging performance The A4 has improved charging performance compared to the A3. This is because the newly developed "hybrid negative plate" has been adopted to shorten charging time and improve charging efficiency. Other A4 has also improved the following points compared to the A3. Engine starting performance Low temperature starting performance Safety Summary The A4 has improved idling stop life, maintenance-free performance, charging performance, engine starting performance, low temperature starting performance, safety, etc. compared to the A3.

The answer from Panasonic is as follows: ・blue battery caos M-65 (N-M65/A4) (actual reference value: 540 / tester setting value: 430) ← At the time of replacement, the charge status was 100%, and the actual measured value was 436CCA, so the SOH (state of health) was over 100% compared to the tester setting value of 430. ・blue battery caos Q-105 (N-Q105/A4) ← This was also mentioned to me. (actual reference value: 785 / tester setting value: 630) {Note} ◆ Actual reference value This CCA value is the actual value when the battery is new and fully charged. The average value was obtained by measuring multiple batteries based on the JIS standard. ◆ Tester setting value Since recent cars are often judged by the tester when the battery is not fully charged due to charging control, etc., we also provide the tester setting value. The tester setting value is a reasonable value derived assuming the diagnosis of our products based on the diagnosis with a tester that inputs the CCA value commercially available in accordance with the actual market situation.
