Motorola xts impres charger

[firebell9137]

Hi does the NNTN7335B battery charge in the motorola v3.40 WPLN4114AR impres charger correctly? Im using the 2800mah version of this battery and it starts chirping low battery at 40% with a lot of capacity still left in it. Also gets to 2 bars at 80% ive intialized it twice so far using the charger mentioned above. Still does it. Standard low battery alert enabled, not early warning. Do i need a new battery or charger or both? Please let me know asap. Thanks. Battery is li-ion

Date code on battery?

213

Without reading it on an Impres battery data reader it's hard to know. The numbers you are posting are not exact. Also the battery with that date code could be as old as 2012 13th week of 12

213 would indeed indicate a battery from March 2012, which means the battery is a decade old at this point. Probably time for a new one.

Motorola switched to four digit date codes around mid 2012, so that date code would now be represented as 1213.

Also note that they normally give the batteries date codes that are a few months ahead of the actual date of manufacture that the IMPRES reader shows. So for example, one of my APX batteries has a date code of 2028 (28th week of 2020, or mid-July), whereas the manufactured date on the IMPRES chip is Feb 27th, 2020. That's nearly half a year's difference. All of my APX, XTS, and XPR batteries follow the same pattern, which means your battery was probably actually manufactured in late 2011.

Agreed. The date codes seem to be when the batteries get to market. They’re made a few months before that. The Impres battery reader shows the exact date they were actually made. It’s an amazing device, & I was lucky to pick one up brand new at the Orlando Ham Fest a few years ago for $35.

Ok thank u everyone. Ill get a new battery.

Oh yeah, to answer your question...the WPLN4114AR is a very capable charger, and while there is firmware newer than 3.4 (3.9 or 3.11 I forget), it mostly addressed issues with APX batteries, so it shouldn't apply to you.
