Their batteries will only last upto around 12 hours only (provided that you don't run at full speed) and afterwards they already need to use the noisy diesel engines to recharge them. In that process, they also need to snorkel for fresh air (although some newer diesel-electric subs have developed more advanced air circulation systems that will allow longer snorkel time intervals).

In this case, if a CBG suspects that a diesel-electric sub is operating in the area they can just deploy further from shore to limit the sub's effectiveness.

The Los Angeles class of the USN is one of the best ASW (anti-submarine warfare) / CBG-escort submarines around. If that is not enough, the USN also has ASW aircrafts that can be deployed (Orion or Viking???). A new ASW aircraft is also in the works.
And one other thing is that diesels are quite slow running on their electric engines, also requires a lot of maintenance. Marami neto is russia and china i think romeo class ata. The akula 2 is also a formidable attack sub kaso talagang advance lang ang LA and improve LA class 688 subs. I guess dedecommision na rin yung mga LA class nakalimutan ko lang kung ano class. sayang yung seawolf class designed as a boomer (missile sub) kaya lang tapos na cold war so not much use for boomers right now. Pero matindi talaga yung sonar rig nya and also yung propulsion system ultra quiet.

Talagang biggest threat ng CBG is from enemy subs kaya matindi ASW screen nyan. Usually FFG with chopper support ( Seahawk with LAMPS system and dipping sonar) kung medyo malapit sa shore with viking and orion support pa tapos outer picket nya usually yung mga LA class. Kung sa surface kasi you need to go through F14's and F18's on CAP, tapos dun sa mga air defense curtain provided by aegis cruisers and DDG's, pag lumapit pa mga 5 inch guns, pag nakalusot pa sa CIWS naman ng carrier. whew

Pero takot pa rin sila sa 1 or 2 person na nababalutan ng TNT ang katawan na nakasakay sa rubber dingy tapos magpapasabog sa sarili pag malapit na sa barko
