Hi,
Do you know a technique to safely attach wires to NMH batteries
("C" cells) without soldering the wires to the battery which may harm the
batteries integrity? Note: I have several new "C" NMH batteries.

I know about battery holders, but there isn't enough space for a
multi-cell battery holder in the project I am working on.

Thank You in advance, John

Solder your wires to contact pads. Coat the positive and negative terminals
with some sort of protective anti-galvanic grease. Use electrical tape to
adhere pads by wrapping the battery lengthwise. Make a C shaped lengthwise
cover made of sheet metal for the battery. Then use a couple of tie wraps
to squeeze the C shaped cover tightly onto the contacts.
