Battery quality?

[brightonkeys]

We usually stock the Renata brand but if we run low can we stock up on Rayovac without feeling we're doing the dirty on our dear customers? I guess what I'm asking is: how much do the different brands truly differ?

I feel most branded batteries ( except vinnic ) are good quality. Like you I stuck to renata, with the occasional box of seiko ( when renata is not available) or siny ( when condor supply them f.o.c.)

batteries are rated in mAh (milliamp Hour) based on a 377

 

Renata & Rayovac are rated at 28 mAh, Vinnic are a lowly 22 mAh Sony is rated at 29 mAh so are on paper the best 377's available.

 

The Seiko Seizaiken brand that cousins sell are a good buy, they rate at 28mAh the same as their Renata batteries but for a 377 are 4p (4.8p if you're not vat registered) per battery cheaper, but theoretically last the same length of time (these are what I've recently started fitting)
