Motorola HNN4003 is the genuine Motorola IMPRES lithium battery for the GP328 & GP338. HNN4003 is 2500mAh in capacity and will allow 14-18 hours of operation between charges.
Note: This battery is the logical replacement for the HNN9013. However it should be noted that this battery is thicker so might not fit into some slimline carry cases.
