Winterized Battery Storage

[davie]

Hello
Is it better to use battery tender on a diesel pusher or leave the motorhome plugged in to shore power for winter storage? Best way to keep the batteries charged and healthy?


Thank You

You will get responses both ways and they both have + / -

I like and use BatteryMinder (TM) maintainers as they have a desulfation mode
+ No need to run your MH charger 24/7 while in storage
+ Available in different ratings - I use a 2A for chassis and adjustable 2,4,8A for my house bank of 8 - 6V GCs
+ No problem w/ GFCI
+ Many storage locations charge extra for plugging in and some will allow maintainers at no $ (My case)
- They are an additional part to buy

Many say just plug it in and use the onboard charger
+ You already have it no addn'l $
+ it is more than capable as long as it is a modern multi-stage charger
- Some MHs don't play well when plugged into GFCI outlets

Either can / will work - weigh the +/- and just decide which you prefer

I'm going to go with the Tender. I went and got them then decided to ask. The charger 24/7 makes sense.

Thanks
