I have an older TENS unit and need a battery. Std. battery is a BL-4C 720mah 3.7vdc LI-ion rechargeable. The batt leads are soldered into the unit's board. It is a very small battery. I cannot find a direct replacement.
I can find larger batteries with leads (will require a custom external mounting), but all have larger mah ratings. How much larger can I go before I burn up the hardware or my test subject?
