Actually, modern Li-ion 9V batteries have basically the same capacity as Alkaline versions (about 600mAh). I have been using the EBL 9V batteries for over two years with my PDVS2mini (who am I to argue with Ian?!). There are also Lithium primary (non-rechargeable) 9V batteries available, such as from Ultralife (1200mAh) and Energizer (800mAh). The Ultralife is a tiny bit larger than nominal, so some tight battery compartments can be an issue. |

Is it common to use 9V rechargeables in them? --- End quote --- Yes. NiMH 9V batteries are fairly useless unless you find the 7-cell variety--and even then they are only about 1/3 the capacity of an alkaline. The EBC 2-cell Li-ion 9V batteries are very good for meters and other devices that work down to 7.0V or lower, they will match or outperform alkalines. Most reasonably well designed devices will fit this description. Apparently the low voltage indicator comes on at about 7.0V on 9V-powered Brymen meters, so all good there. |
