I ordered these batteries to have extras to swap out quickly when needed. I ordered the charger too. Always ready now.
I ordered this battery to replace a 6 year old that wasn't hold a charge as long as it used to. For the money and piece of mind that this is a good battery, why not get the mfg. version? And it is 700mah more than the one in it. Fits and works perfectly!
Very good and very happy 👍👍👍
