Kevin;
I agree with Monte.
I've had two Autometer Battery Extenders Model 9202 since they first made them back in the 80's. The first one lasted over 20 years and then they sold me another one cheap which I still use, a lot.
They have an aluminum finned outer shell that does get hot if the battery is heavily depleted but after an over night charge the battery is usually fully charged.
This model 9202 is rated at 1 amp charge with 250 milliamp maintenance rate. A lot of us veterans have these stopped using a regular charger (except at the track) years ago.
