Review on 🔋 VONIKO Alkaline 9V Batteries - 4 Pack - Long-Lasting with a 7-Year Shelf Life by James Newbill

I risked a 9v battery from this brand as I had never heard of it before but I am very happy with the purchase. Fast delivery. The packaging was perfectly clean, looked new and didn't look tampered with. The date stamp on each battery reads 10/2026, which pretty much matches the stated expiration date. each of the 4 batteries in the package. (See photo) <1mm higher than one of the famous brands 9v <0.5mm thicker. TINY. Suitable for all devices that I use with 9 V. Very happy with the purchase, highly recommended! TL; DRN Now they are slightly different in size than the standard 9v from one of the well known big brands. The case is slightly taller, but the contacts are shorter, which almost makes up for the difference. Also a little thicker. If your device is a VERY SPECIFIC, VERY VERY DIFFICULT SPACE for battery size, like a smoke alarm, I suggest measuring the outlet first. The measurements I took with a millimeter ruler are as follows: case height 45mm + contact height 2mm = total height 47mm x 25mm width x 16mm thickness. The famous brand measures 46mm H x 25mm W x 15.5mm thick. Very close. The obvious difference is only in the height of the case, but if you look at the contacts, the difference is less than a millimeter. Convert to inches online if needed.
