I have a HP pavilion dv5215us. My original reg capacity batt still works fine. I ordered an aftermarket hi-cap and 2 in a row do the following:

1. HP Battery Check: every 2 minutes, (red) replace flashes and sometimes pwr % drops.....then comes back to normal charging (green).

2. On battery pwr, laptop slows down and or freezes every 10 minutes or so.....after a minute it comes back alive. Sometimes on batt pwr the batt indicator by the clock drops and then comes right back up. If I plug in ac during the slow down, it speeds right back up. Works perfectly on ac and orig batt.

3. Is there anything i can do or are they both bad, or just incompatible? Previously I had a hi-cap aftermarket batt from a diff mfg and it was fine.
