No disrespect, but BL-5J form factor Li-ion batteries cannot produce 245mAh. The higher capacity batteries of ca. 1500mAh achieved this by being slightly thicker. So, if your battery is good, it will be between 1300 and 1500mAh. Many batteries with inflated capacity claims oroved to be <1000mAh but some were ok. See the old and still interesting thread on the subject.
