MTS2000 battery & charger questions

[Comms13]

I'm getting so much conflicting info online about which batteries work with which chargers. Anyone with knowledge of the following model numbers, any help would be appreciated.

I have:
Three NTN7144 batteries (used)
One WPNN4013 battery (new) - which says I cannot use with the NTN1174A charger.
Two NTN1174A chargers (used)

I put the 7144 batteries into the chargers I have for like 10hrs each and the charge indicator never shut off.

I have friends who both have the NTN7209A chargers so I have a feeling that my chargers are not the proper chargers. I'm ill be getting a 7209A charger soon, I just want to make sure it's safe to use with the two batteries I have.

This is probably confusing, but any help is appreciated.

NTN1174x chargers are slow rate chargers, For the 7144 battery, 16 to 18 hours charge time. The indicator does not ''shut off".

You can charge the NiCad WPNN4013 battery in the NTN1174 charger but it will take forever. 20+ hours.

Wow. Okay. So I really am better off getting the NTN7209A charger for both batteries huh?

So I have a NTN7209A charger now. I put three aftermarket 7144 batteries on that charger and it only rapid charged for about 5 mins before going green to a slow rate charge.....

All of those batteries were used and fairly old, but I don't know if it's them or a bad charger.

The WPNN4013 battery I have is also NiMH and is brand new. I'm afraid to put it in the 7209 charger! Lol

You want to use the NTN8831A charger. The 7209 charger is from the last century. The 8831 charger is good for all 3 chemistries, & charges Sabers, XTS3000/5000, as well as the MTS radios. I have picked them up for as low as $10 at hamfests.

Will it charge both batteries? The NTN7144 and the WPNN4013A? I'm getting really really confused with all of the Motorola battery and charger options.... It's annoying lol.

Tri Chem means it will charge them ALL.

Anyone else have experience using this charger?
