TWL6032: TWL6032 precharge stops unexpectedly

Part Number: TWL6032

Dear,

We are using TWL6032 + omap4460 for our product, and met some problem on battery charging.
Capacity of the battery we are using is 3600mAh.
While battery is over discharged, connecting charger to the device, precharge will start automatically by TWL6032.
The problem we are facing is sometimes precharge will stop after about 14 minutes before it's finished successfully(battery voltage reaches 3.35V).
For this issue, we checked TWL6032 data manual and found that there is a safty timer for precharge period.
Two options are offered about the safty timer, for the customer specific charger, which are 14 minutes and 29 minutes.
Seems like TWL6032 module we ordered selected 14 minutes, it's not appropriate for the battery we are using.
We would like to change the precharge timer to 29 minutes, but this value was programmed in OTP memory.
Could you please give your direction on how to handle this issue?

Many thanks
