7Ah, 8Ah, 9Ah
The 12V 7Ah Battery Story
The 7Ah, 8Ah, 9Ah are a sealed valve-regulated lead acid battery (VRLA for short) and one of the most popular sizes used in UPS Backup, Alarm and Electric Scooter applications. Many of these devices came with a Yuasa NP7-12 battery. Depending on the application it will either have F1 (0.187" wide) terminals or F2 (0.250" wide) terminals. Over the years as technology has improved the 12V 7Ah battery has been upgraded to the 12V 7.2Ah battery, 12V 7.5Ah battery, 12V 8Ah battery and now a 12V 9Ah. They are all the same physical size and of the same voltage. The only difference is that the 9Ah will last nearly 30% longer between charges compared to the original 12V 7Ah amp batteries. No harm will come to your system from increasing amperage.
